Myopic Laser Vision Correction means using laser surgery to fix myopia, also called nearsightedness. Myopia is when your eye can see things that are close clearly, but things far away look blurry. This happens because the eye is too long or the front surface (cornea) is too curved, so light focuses in front of the retina instead of on it. Laser vision correction reshapes the cornea so light lands correctly on the retina, giving clearer distance vision without glasses or contacts. Cleveland ClinicMayo ClinicAAONational Eye Institute
Myopic laser vision correction is a group of eye procedures that use precise lasers to reshape the cornea (the clear front surface of the eye) to reduce or eliminate nearsightedness (myopia), so distant objects appear clearer without glasses or contacts. The laser removes microscopic amounts of corneal tissue, changing its curvature so light focuses properly on the retina. This permanent modification improves vision by correcting the refractive error caused by an eyeball that is too long or a cornea that is too steep. The most common techniques are LASIK, PRK (and its variants), and SMILE. These procedures are alternatives to glasses or contact lenses when the prescription is stable and the patient is properly screened. Mayo Clinic Verywell Health NCBI
Every word here is simple: myopia = nearsightedness; laser = focused light that removes tiny bits of tissue; vision correction = making eyesight better; cornea = the clear front window of the eye; retina = the light-sensing layer in the back of the eye. The goal is to reduce or eliminate the need for glasses by changing how the eye bends light. NCBI
Types of Myopic Laser Vision Correction
There are several main types. Each uses a laser but in slightly different ways:
LASIK (Laser-Assisted In Situ Keratomileusis): A thin flap is made on the cornea, lifted, and then a laser reshapes the inside part. The flap is put back and heals quickly. Recovery is fast and most people see well within a day or two. InSight Vision CenterMayo ClinicAssil Gaur Eye Institute
PRK (Photorefractive Keratectomy): The very top layer of the cornea is removed (no flap), and the laser reshapes the surface directly. Healing is slower than LASIK, and vision improves over days to weeks, but it is equally effective for correcting myopia. Assil Gaur Eye Institute
SMILE (Small Incision Lenticule Extraction): A laser creates a tiny lens-shaped piece (lenticule) inside the cornea. That piece is removed through a small cut, reshaping the cornea from within. There is no large flap, and healing is generally stable with less nerve disturbance. SMILE is mainly for nearsightedness (myopia) with or without mild astigmatism. Mayo Clinic
LASEK / Epi-LASIK: These are variations where the very surface layer is loosened and moved aside (instead of removed completely like PRK), then the laser reshapes the cornea and the layer is replaced. Recovery sits between PRK and LASIK in speed and discomfort. (Often grouped with surface ablation techniques.) Assil Gaur Eye Institute
Wavefront-guided / Custom Ablation: This is not a separate surgery but a way the laser treatment is tailored. A detailed map of the eye’s imperfections is made (wavefront aberrometry), and the laser uses that map to correct not just basic nearsightedness but subtle optical distortions to try to improve quality of vision. NCBI
Other alternatives (for context): Although not strictly “laser” reshaping, some people with high myopia may consider implantable lenses (like ICL) or refractive lens exchange; these are mentioned sometimes alongside laser options but work by adding or replacing optical elements rather than reshaping the cornea. NCBI
Each type has trade-offs in comfort, healing time, and suitability depending on corneal thickness, lifestyle, and the exact degree of myopia. Proper testing before surgery decides which type fits best. EyeWikiAAO Journal
Causes / Risk Factors of Myopia
Myopia usually comes from a mix of inherited traits and things in a person’s life or environment. Here are 20 causes or strong risk factors, each explained simply:
Family history / Genetics: If one or both parents are myopic, a child is much more likely to become myopic. The risk increases if both parents have myopia. PMCPMC
Early onset of myopia: Children who develop nearsightedness at a younger age tend to progress farther. Early starting is itself a marker of higher risk. IOVS
High educational pressure: Spending long hours studying, especially in intensive school systems, is linked to more myopia. This is likely through prolonged near work. PMCIOVS
Excessive near work: Reading, writing, or working close up for long periods without breaks increases risk. Looking at small print or focusing closely strains and is associated with myopia development. PMCBioMed Central
Prolonged screen time / digital device use: Time on phones, tablets, or computers at close distances adds to near work load and is correlated with myopia, especially in children. BioMed Central
Limited time outdoors: Less exposure to natural daylight is one of the strongest modifiable risk factors; playing outside slows myopia onset. Sunlight may trigger chemical signals in the eye that protect against elongation. BioMed CentralIOVS
Urban living: Children in cities get less outdoor time, more near work, and environmental differences that together raise myopia rates compared to rural areas. IOVS
Ethnicity: Certain ethnic groups (e.g., East Asian populations) have higher prevalence of myopia, influenced by both genetics and lifestyle patterns. IOVS
Higher socioeconomic status: This is tied to more schooling and indoor activities, indirectly raising myopia risk through lifestyle. PMCIOVS
Short working distance: Holding books or devices very close increases the focusing demand and is linked to higher myopia risk. PMC
Accommodative lag: If the eye has trouble accurately focusing for near tasks, this mismatch may drive the eye to grow longer, worsening myopia. PMC
Use of corrective lenses that do not control peripheral defocus: Traditional glasses can leave the peripheral image focused behind the retina, which may promote eye elongation in some theories (basis for modern myopia control optics). IOVS
Low light environments: Studying or reading in dim lighting might contribute indirectly by encouraging close, prolonged near work and reducing outdoor light exposure. BioMed Central
High cognitive/academic engagement: Correlations exist between high IQ or intense academic involvement and myopia, likely via more near-focused tasks. PMC
Parental myopia severity: Not just presence but how severe parents’ myopia is can influence a child’s risk and progression. PMCPMC
Genetic variants identified in genome studies: More than hundreds of gene locations have been linked to myopia and its progression, making some individuals genetically prone beyond family history alone. PMC
Myopia progression due to lack of intervention: If early myopia is left unchecked (no control strategies like outdoor time or low-dose atropine), it tends to worsen over time. IOVS
Lifestyle shifts (e.g., more indoor life, less active play): Modern life with less active outdoor play contributes to growing myopia prevalence. BioMed Central
Premature birth / low birth weight: Some evidence links early birth or lower birth weight to altered eye growth patterns, raising risk of refractive errors including myopia. IOVS
Interaction of genes and environment: The effect of activities like near work is stronger or weaker depending on a person’s genetic background; the two work together. PMCIOVS
Symptoms of Myopia (Nearsightedness)
These are the common signs a person might have myopia, explained in simple language:
Blurry vision for far objects: Distant things like road signs, whiteboards, or TV appear fuzzy. Mayo ClinicAAO
Squinting to see better: Narrowing the eyes temporarily helps focus and sharpen distant vision. Mayo ClinicAAO
Eyestrain or tired eyes: When trying to see clearly far away, the eyes get tired and uncomfortable. Mayo ClinicAAO
Headaches: Often from squinting or struggling to focus, especially after reading or trying to see distant objects. Mayo ClinicAAO
Need to sit close to screens or boards: Children may sit near the TV or in the front row at school to see clearly. Verywell Health
Difficulty seeing while driving, especially at night: Distant lights can appear glarey or fuzzy. AAO
Frequent blinking or eye rubbing: Trying to clear vision or relieve discomfort from straining. Verywell Health
Poor performance in school due to not seeing the board: If a child can’t see distance, they may seem inattentive or perform worse. Mayo Clinic
Eye fatigue after visual tasks: Eyes feel heavy or sore after trying to look at distant objects. Mayo Clinic
Difficulty reading road signs while moving: Signs blur as the person drives by. AAO
Need for more light to see distant things: Brightening the environment helps, because the eyes work harder in dim light. BioMed Central
Reduced contrast sensitivity: Far objects may blend into backgrounds, making them harder to distinguish (common in uncorrected refractive error). NCBI
Delayed recognition of faces or objects far away: It takes longer to identify people or signs at a distance. Mayo Clinic
Avoiding outdoor activities that require good distance vision: Children may choose not to play sports or look distant because they cannot see clearly. AAO
Frequent changes in prescription needed: Rapid shift in how the eye focuses, noted by needing stronger glasses often, especially in growing children. IOVS
Diagnostic Tests for Myopia and Suitability for Laser Vision Correction
Before doing laser correction, doctors perform a set of tests to confirm myopia, measure eye shape, and decide if the eye is safe to treat. These are broken into categories:
Physical Exam
Visual Acuity Testing – Measures how well someone sees at distance and near using charts (e.g., “read the letters on the wall”). This confirms blurred far vision typical of myopia. EyeWikiAAO Journal
Refraction (Objective and Subjective) – Uses machines and trial lenses to determine the exact prescription needed to correct vision. Subjective refinement (patient feedback) ensures accuracy. EyeWikiAAO Journal
Cover Test / Ocular Alignment Check – Checks whether both eyes work together properly. Misalignment can affect perceived vision and suitability for surgery. AAO Journal
Slit-Lamp Examination – A lighted microscope is used to look closely at front parts of the eye (cornea, lens, conjunctiva) to rule out disease or scarring that could interfere with surgery. EyeWikiAAO Journal
Pupillary Reaction and Size Measurement – Tests how pupils respond to light and measures their size, since large pupils can affect visual quality after surgery, especially in low light. AAO Journal
Manual / Functional Tests
Keratometry – Measures the curve of the front of the cornea. This helps determine how much the eye is bending light and is essential for planning the laser reshaping. PMC
Corneal Topography – Creates a detailed map of the cornea’s shape to detect irregularities (like early keratoconus) that could make laser surgery unsafe. PMC
Pachymetry – Measures corneal thickness. Thin corneas may not be safe for some laser procedures because too much tissue removal could weaken the eye. EyeWikiPMC
Tear Film Assessment (e.g., Schirmer’s Test, Tear Break-Up Time) – Checks for dry eye. Poor tear film can cause discomfort after surgery and affect vision quality. EyeWikiAAO Journal
Intraocular Pressure Measurement (Tonometry) – Ensures normal eye pressure; high pressure may indicate glaucoma, which needs management before any elective surgery. AAO Journal
Lab / Pathological Tests
Blood Glucose or HbA1c – If a patient has diabetes or poor blood sugar control, healing can be affected and vision can fluctuate; checking helps ensure stable, safe outcomes. AAO Journal
Conjunctival Swab / Infection Screening – If there are signs of redness or discharge, cultures can rule out infection before the eye is touched by lasers. EyeWiki
Pregnancy Test (for women of childbearing age) – Pregnancy can change the eye’s refraction temporarily due to hormonal shifts; surgery is usually delayed until vision stabilizes. AAO Journal
Electrodiagnostic Tests
Visual Evoked Potentials (VEP) – Measures how the brain responds to visual signals. It can help rule out optic nerve problems if vision issues are unclear or atypical. NCBI
Electroretinography (ERG) – Tests the electrical function of the retina, especially in high myopia where retinal health must be known before surgery. NCBI
Imaging Tests
Wavefront Aberrometry – Measures tiny imperfections in how the eye focuses light. This map allows “custom” laser treatments to improve quality of vision, not just clearance of blur. NCBI
Optical Coherence Tomography (OCT) – Takes cross-sectional pictures of the retina and optic nerve to ensure no hidden disease that could affect vision or healing. NCBI
Fundus Photography – Pictures of the back of the eye to document retinal health and track any changes over time, especially important in high myopia. AAO Journal
Scheimpflug Imaging / Pentacam – Advanced imaging of the cornea’s front and back surfaces and depth, giving a 3D view to pick up early weakness or abnormal curvature. PMC
Axial Length Measurement (Optical Biometry / A-scan) – Measures the length of the eye; longer eyes have more myopia and higher risk of complications. It helps confirm the degree of myopia and plan surgery. AAO Journal
Non-Pharmacological Treatments
Preoperative Screening and Optimization: Careful evaluation (topography, pachymetry, tear film assessment) identifies unsuitable corneas (e.g., keratoconus) and treats surface problems before surgery to reduce complications and improve outcomes. Wikipedia
Eyelid Hygiene and Meibomian Gland Care: Cleaning eyelid margins and expressing meibomian glands before and after surgery improves tear film quality, helping prevent or reduce postoperative dry eye by normalizing lipid layer function. PMC
Warm Compresses: Applying warm compresses improves meibomian gland secretion, stabilizing the tear film and reducing evaporative dry eye symptoms that can worsen after laser surgery. PMCScienceDirect
Bladeless Flap Creation (Technique Choice): For LASIK, using femtosecond lasers to create the corneal flap (instead of microkeratomes) can reduce mechanical trauma and enhance precision, indirectly improving healing and reducing certain risks. ScienceDirect
Avoiding Eye Rubbing: Rubbing the eyes can displace the corneal flap or cause microstriae, leading to vision distortion or need for retreatment. Patients are taught to resist rubbing, especially in early healing. lucentvision2020.com
Protective Eyewear/Postoperative Shields: Wearing eye shields, especially while sleeping in the immediate postoperative days, prevents accidental trauma or pressure on healing tissue that could dislocate flaps or disrupt epithelial healing. Cornea & Laser Eye Institute
Humidifier Use and Environmental Control: Maintaining moderate ambient humidity reduces tear evaporation, supporting corneal surface stability and alleviating dry eye symptoms as the corneal nerves recover. PMC
Blink Training and Digital Screen Breaks: Conscious blinking and limiting prolonged screen exposure prevent tear film break-up and reduce strain, helping the ocular surface recover more comfortably after surgery.
Patient Education and Compliance Coaching: Teaching patients what to expect, how to use drops, and warning symptoms improves adherence and early reporting of complications, which is crucial for safe recovery. Cornea & Laser Eye Institute
Cold Compresses for Immediate Discomfort: While warm compresses help gland function, gentle cold compresses in the first hours can reduce mild inflammation and discomfort, making early recovery more tolerable. (Common postoperative advice from clinical practice guidelines; inference from general inflammation management.)
Optimizing Systemic Health (Hydration and Blood Sugar Control): Good hydration keeps mucous membranes moist; controlling diabetes and systemic inflammation supports wound healing and reduces infection risk. Cornea & Laser Eye Institute
UV Protection with Sunglasses: Postoperative corneal tissue is more susceptible to UV-related oxidative stress; wearing UV-blocking sunglasses protects healing cells and reduces inflammation. (Standard refractive surgery aftercare guidelines; inference from ocular surface protection principles.)
Smoking Cessation Before and After Surgery: Smoking impairs microvascular healing and increases oxidative stress, potentially delaying epithelial recovery and increasing inflammation. (General wound healing principles; high clinical consensus.)
Sleep Hygiene: Adequate sleep helps systemic repair processes and reduces rubbing risk from eye itching; it also reduces ocular surface dryness through longer eye closure. (General recovery recommendation; inference.)
Avoiding Contact Lens Use Preoperatively: Discontinuing contact lenses ahead of surgery allows the cornea to return to its natural shape, improving measurement accuracy and surgical planning. Verywell Health
Tear Film Optimization with Non-Medicated Lubrication: Frequent preservative-free artificial tears (as a mechanical support) prepare the surface by keeping epithelium hydrated, reducing early postoperative discomfort. PMC
Ocular Surface Demarcation and Mapping: Using advanced imaging to understand corneal irregularities ensures personalized ablation profiles and avoids treating unstable or abnormal areas. Wikipedia
Cold Avoidance of Irritants (Makeup, Dust): Staying away from makeup, smoke, and dust in early recovery reduces foreign-body irritation and infection risk. Precision Vision London
Follow-up Scheduling and Early Detection Protocols: Structured postoperative visits catch problems like flap displacement, infection, or epithelial defects early before they worsen. EyeWikiChicago Cornea Consultants
Visual Expectation Management (Staged Enhancements): Planning for potential minor enhancements and explaining that vision may fluctuate initially reduces anxiety and unnecessary self-interventions. Cornea & Laser Eye Institute
Drug Treatments (Postoperative and Complication Management)
Topical Antibiotics (e.g., Moxifloxacin, Gatifloxacin): These are given immediately after surgery—typically one drop 4 times daily for 5–7 days—to prevent bacterial infection of the corneal interface or surface. The mechanism is inhibition of bacterial DNA gyrase/topoisomerase, stopping replication. Side effects can include mild irritation, rare allergic reactions, and ocular surface toxicity with prolonged use. PMC
Topical Corticosteroids (e.g., Prednisolone Acetate, Loteprednol): Used for 1–2 weeks starting frequently (every 2–4 hours) then tapered to reduce inflammation, haze (especially after surface procedures), and promote smoother healing. They work by blocking inflammatory cytokine pathways. Side effects include increased intraocular pressure (glaucoma risk), cataract formation with long-term use, and increased susceptibility to infection if misused. AAOPMC
Topical Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) (e.g., Ketorolac, Bromfenac): These reduce postoperative pain and inflammation by inhibiting prostaglandin synthesis. They are usually applied 1–2 times daily for several days. Rare complications include corneal melt in susceptible individuals and surface irritation. PMC
Lubricating Eye Drops (Preservative-Free Artificial Tears): Though not “drugs” in the disease-modifying sense, frequent use supports healing, reduces discomfort, and mitigates transient dry eye by replacing and stabilizing the tear film. These are often used hourly initially. PMC
Topical Cyclosporine A (e.g., 0.05%): For patients with persistent or neurotrophic epitheliopathy–related dry eye, cyclosporine reduces ocular surface inflammation and improves tear production by modulating T-cell activity. It is typically used twice daily for months. Side effects include burning on instillation. Healio Journals
Combined Antibiotic–Steroid Formulations (e.g., Moxifloxacin + Dexamethasone): These provide simultaneous prophylaxis and inflammation control, simplifying regimens. They are used early post-op; the combination is safe and effective when dosed per ophthalmologist instructions (often 4 times daily initially). PMC
Oral Analgesics (e.g., Acetaminophen or NSAIDs): Used for mild to moderate discomfort immediately after surgery. They work systemically to inhibit pain mediators (NSAIDs) or centrally modulate pain perception (acetaminophen). Use should account for contraindications (e.g., kidney disease for NSAIDs). (Standard postoperative care—common clinical practice.)
Topical Antiglaucoma Monitoring if Steroid Responder: In patients who develop elevated intraocular pressure from steroids, agents like timolol or brimonidine may be temporarily prescribed to control pressure until steroid tapering reduces the spike. AAO
Antibiotic Prophylaxis for Delayed Infection (Culture-Guided if Suspected): If signs of infection emerge later, more targeted antibiotics (e.g., fortified vancomycin or fluoroquinolone) might be used after culture. Early detection is key to prevent vision loss. EyeWikiChicago Cornea Consultants
Adjunctive Tear-Promoting Agents (e.g., Sodium Hyaluronate drops): Some advanced lubricants contain hyaluronic acid to increase residence time and foster epithelial healing in early postoperative dry eye. These are used multiple times daily. PMC
Dietary Molecular Supplements
Lutein (10 mg/day) and Zeaxanthin (2 mg/day): These carotenoids accumulate in the macula and act as antioxidants and blue-light filters. They reduce oxidative stress in retinal tissues, support overall ocular health, and may help stabilize vision recovery over time. PMCPMC
Omega-3 Fatty Acids (EPA/DHA, 1000–2000 mg combined daily): These reduce ocular surface inflammation, support meibomian gland function, and help prevent or lessen dry eye symptoms by modulating inflammatory eicosanoids. riverheightseyecare.comSaddleback Eye Center
Vitamin C (500 mg twice daily): Important cofactor for collagen synthesis, vitamin C supports corneal tissue repair and acts as an antioxidant to reduce oxidative damage during healing. Natural sources like citrus are preferred, but supplements can ensure adequate levels. clearviewinstitute.com
Zinc (25–40 mg elemental daily, with copper if long-term): Zinc is essential for wound healing and high retinal enzymatic activity; it also supports immune function to reduce postoperative infection risk. This is part of formulations like AREDS for eye health. Prevention
Vitamin A (as beta-carotene or retinol, appropriate daily allowance): Supports epithelial surface integrity and mucin production, helping maintain a healthy tear film. While not effective for myopia control, it aids overall ocular surface recovery. AOA
Vitamin E (400 IU or dietary equivalent): A lipid-soluble antioxidant that protects cell membranes from oxidative injury during healing; often paired with other antioxidants for synergistic effect. Vogue
Bilberry Extract (standardized anthocyanins, e.g., 80 mg twice daily): Thought to have antioxidant and microcirculatory support effects, potentially helping with eye comfort, though strong clinical evidence is limited—used as supportive eye health supplement. (Common supplement use; moderate evidence.)
Astaxanthin (4–8 mg/day): A potent antioxidant that may reduce ocular inflammation and support cell membrane stability in ocular tissues after surgical stress. Emerging evidence suggests benefit in oxidative ocular conditions. (Inference from antioxidant properties; growing literature.)
N-Acetylcysteine (600 mg once or twice daily): Precursor to glutathione, supports cellular antioxidant defenses and may aid ocular surface healing by reducing oxidative stress. Used cautiously based on systemic tolerance. (Mechanistic inference from antioxidant pathways.)
Hydration with Electrolyte Support (adequate water plus moderate sodium/potassium balance): Proper hydration supports tear film production and helps maintain mucous membrane health, indirectly aiding postoperative comfort and surface healing. (General physiologic principle.)
Regenerative / “Hard Immunity” / Stem Cell–Related Therapies
Cenegermin (Recombinant Human Nerve Growth Factor, rhNGF, 20 µg/mL, one drop six times daily for eight weeks): Approved for neurotrophic keratitis, this topical growth factor promotes corneal nerve regeneration and epithelial healing by stimulating sensory nerve survival and function, helping restore trophic support to the corneal surface. PMCMDPI
Autologous Serum Eye Drops (typically 20–50% dilution, 4–6 times daily): Made from the patient’s own blood, these drops supply growth factors (EGF, vitamin A, fibronectin) and anti-inflammatory components to accelerate epithelial healing and provide lubrication. They are used in persistent epithelial defects and post-surgical surface healing. PubMedResearchGateIris
Platelet-Rich Plasma (PRP) Eye Drops: Derived from the patient’s plasma, PRP contains concentrated growth factors that can enhance epithelial recovery and modulate inflammation after surface injury; studies show benefit in ocular surface healing though limited effect on nerve sensitivity recovery. Healio Journals
Blood-Derived (Other Serum-Based) Eye Drops (e.g., Plasma Rich in Growth Factors or Specialized Serum Formulations): These support healing in severe ocular surface disease by delivering endogenous cytokines and factors that restore integrity of epithelium, often used when standard therapy fails. ScienceDirect
Amniotic Membrane (as Biological Scaffold, often in persistent defects): Though a procedural implant rather than a pill, it provides anti-inflammatory cytokines, promotes epithelial migration, and reduces fibrosis, which can be used in refractory surface healing or to prevent ulceration. PMCEvolve Medical Education
Limbal Stem Cell Support / Transplantation (for severe surface failure): In extreme cases of surface breakdown not healing with conventional therapy, limbal epithelial stem cell transplants restore the regenerative cell population of the corneal surface, rebuilding a healthy epithelium. (Used in advanced ocular surface disease; inferred extension of regenerative strategies.) PMC

Frequently Asked Questions (FAQs)
What is the difference between LASIK, PRK, and SMILE?
LASIK creates a flap and reshapes the inner cornea, PRK reshapes the surface without a flap, and SMILE removes a lenticule through a small incision; all correct myopia but differ in recovery speed and suitability. Mayo ClinicNCBINethradhama Eye HospitalAm I a good candidate for myopic laser vision correction?
You need stable vision (no recent prescription changes), sufficient corneal thickness, healthy ocular surface, and no contraindicating diseases like keratoconus or uncontrolled autoimmune conditions. Screening tests like topography and pachymetry determine candidacy. WikipediaHow long is recovery after surgery?
LASIK patients often see significantly better vision within 1–3 days; PRK and surface procedures take longer (weeks) as the epithelium heals. SMILE recovery is similar to LASIK but may have slightly different nerve healing patterns. Kraff Eye InstituteWill I feel pain after the procedure?
Discomfort is usually mild with LASIK; PRK can cause more soreness for several days. Pain is managed with lubricants and sometimes oral analgesics. Kraff Eye InstituteWhat are the most common side effects?
Dry eye, glare, halos, or temporary vision fluctuations are common early. Most resolve within months; persistent issues need follow-up.Can the correction wear off?
Most corrections are long-lasting, but age-related changes (like presbyopia or cataracts) can affect vision later. Some patients may need enhancements. Verywell HealthIs the surgery safe?
With proper screening and modern techniques, safety is high, though rare complications (infection, ectasia, flap issues) still occur—prevention and early treatment are key. EyeWikiPMCWhat if I develop dry eye after surgery?
Treatment includes lubricating drops, eyelid hygiene, thermal therapies, and in persistent cases, prescription agents like cyclosporine or regenerative drops such as autologous serum. PMCHealio JournalsCan I wear contacts before or after surgery?
Contacts must be stopped before surgery to get accurate measurements; after surgery, you generally don’t need them, but some may use them temporarily during healing or for fine adjustments. Verywell HealthWhat are warning signs after surgery?
Severe pain, sudden vision loss, redness with discharge, or flap movement sensations require immediate medical evaluation. EyeWikiVisual Aids CentreCan nutrition help my recovery?
Yes. Vitamins C, A, zinc, omega-3s, lutein/zeaxanthin, and adequate protein support tissue healing, reduce inflammation, and stabilize the ocular surface. clearviewinstitute.comSaddleback Eye CenterPMCWhat should I avoid after surgery?
Avoid eye rubbing, swimming pools or hot tubs initially (infection risk), dusty environments, and heavy makeup. Also limit activities that risk eye trauma. Cornea & Laser Eye Institutelucentvision2020.comCan I get an enhancement if I’m under- or over-corrected?
Yes. If the residual refractive error is significant and the cornea remains healthy, a controlled enhancement can fine-tune vision. Cornea & Laser Eye InstituteIs laser vision correction permanent?
The corneal reshaping is permanent, but natural aging changes (like presbyopia or cataracts) may still require glasses later. Verywell HealthHow do regenerative therapies like autologous serum help?
They supply natural growth factors and nutrients for faster epithelial healing and better surface stability, especially in cases of non-healing defects or severe dry eye. PubMedResearchGateScienceDirect
