Lipid Keratopathy

Lipid keratopathy means fat (lipid) gets deposited inside the clear front window of the eye, called the cornea. The cornea is normally crystal-clear and has no blood vessels. In lipid keratopathy, cholesterol and other fats leak into the corneal tissue, usually from new, abnormal blood vessels that have grown into the cornea after irritation or injury. These lipids then collect in the corneal layers and can look whitish, yellow-white, or shimmering. Over time, the deposits can scatter light, reduce clarity, and blur vision.

Lipid keratopathy is a condition where fatty material (lipids) builds up inside the cornea—the clear front window of your eye. These pale yellow-white deposits scatter light and can cause blur, glare, halos, and sometimes double vision in one eye. Most cases happen after new, abnormal blood vessels grow into the cornea (a process called corneal neovascularization). Those vessels act like tiny “leaky pipes,” letting cholesterol and other fats seep into the corneal layers next to them. Less often, lipid can form without prior disease (called primary lipid keratopathy), but that is rare. In primary cases, blood cholesterol is usually normal; in secondary cases, it follows inflammation, infection, injury, or long-standing surface disease that invited vessels to grow. PMCEyeWiki

Simple idea:

• “Lipid” = fats like cholesterol and triglycerides.

• “Keratopathy” = disease of the cornea.

• Put together: fatty deposits in the cornea that shouldn’t be there.

The cornea is a transparent, curved tissue. It stays clear because:

• It has orderly collagen fibers that let light pass through.

• It lacks blood vessels, so there is no red blood or fat floating through it.

• It gets oxygen from the air and nutrients from the tears and the fluid inside the eye.

When the cornea is irritated or starved of oxygen, the body may send new blood vessels into it (called corneal neovascularization) to “help” heal. These new vessels are leaky. Fat particles (lipoproteins) can seep out and settle in the corneal layers. The body’s clean-up cells (macrophages) swallow the fat and turn into foam cells, and cholesterol crystals can form. This cycle—vessels → leak → fat → more inflammation—can keep going unless the trigger is treated.

Types of lipid keratopathy

1. Secondary lipid keratopathy (most common)

   • What it is: Lipid deposits happen after the cornea grows new blood vessels because of a problem (infection, inflammation, injury, contact-lens hypoxia, etc.).

   • Key sign: Lipid often lies next to the abnormal vessels.

2. Primary lipid keratopathy (rare)

   • What it is: Lipid collects in the cornea without obvious corneal blood vessels.

   • Why it happens: Sometimes linked to body-wide lipid disorders (abnormal cholesterol/triglycerides) or rare inherited conditions.

   • Key point: Doctors must rule out other corneal diseases that also show crystals or lipids.

3. By location

   • Peripheral: At the edge of the cornea; often linked to inflammation at the margin (for example, blepharitis-related problems).

   • Central/Paracentral: Near the visual axis; more likely to affect vision.

4. By activity

   • Active: Ongoing inflammation and new vessels with fresh lipid appearing.

   • Inactive/Stable: Lipid remains as a scar after inflammation has calmed and vessels are quiet.

5. By appearance

   • Non-crystalline: Hazy, yellow-white clouding.

   • Crystalline: Sparkling, reflective points if cholesterol crystals are present.

Common causes

The theme is the same: anything that makes new, abnormal corneal blood vessels or chronic inflammation can set the stage for lipid to leak in.

1. Long-term contact-lens overwear (especially low-oxygen lenses)

   • How it causes lipid: Lack of oxygen (hypoxia) → new vessels grow → fat leaks from these vessels.

2. Herpes simplex keratitis (HSV)

   • Viral corneal infection can cause scars and vessels; later, lipid collects near those vessels.

3. Herpes zoster ophthalmicus (shingles involving the eye)

   • Triggers inflammation and scarring; vessels may grow into the cornea → lipid deposition.

4. Interstitial keratitis (including syphilitic)

   • Deep corneal inflammation creates new vessels and lipid can settle along them.

5. Trachoma (chronic chlamydial eye disease)

   • Long-standing surface scarring and vascularization → lipid in affected zones.

6. Bacterial keratitis (ulcers)

   • Infection + ulcer leads to repair with new vessels; later lipid can appear.

7. Fungal keratitis

   • Often deep, chronic; vessels form during healing → lipid leakage.

8. Acanthamoeba keratitis

   • Severe, painful corneal infection; vessels may later develop → lipid deposits.

9. Mooren’s ulcer

   • Autoimmune-type peripheral ulcer with prominent vessels; lipid often builds around the damaged rim.

10. Peripheral ulcerative keratitis (PUK) from rheumatoid arthritis or vasculitis

    • Immune attack on edge of cornea; vessels + inflammation encourage lipid deposition.

11. Terrien’s marginal degeneration

    • Thinning at the corneal edge with superficial vessels; lipid may appear near the thinning.

12. Keratoconus with acute hydrops (and chronic irritation)

    • Structural weakening and healing can invite vessels in some cases → lipid later.

13. Chemical or thermal burns

    • Severe surface damage → healing with abnormal vessels → lipid.

14. Penetrating or blunt corneal trauma

    • Deep injury makes the cornea call in vessels for repair; fat leaks into the repair sites.

15. Post-surgical changes (e.g., after pterygium removal, PKP/PRK/LASIK in inflamed eyes)

    • Surgery in a cornea that later gets inflamed or vascularized can lead to lipid deposits.

16. Limbal stem cell deficiency (LSCD)

    • The stem-cell barrier at the edge fails; surface becomes unstable, invites vessels, then lipid.

17. Ocular rosacea/blepharitis (chronic eyelid margin disease)

    • Oil gland dysfunction and inflammation fuel surface irritation and sometimes vessels, with lipid later.

18. Exposure keratopathy (poor eyelid closure, lagophthalmos)

    • Drying and irritation from incomplete blink → inflammation, vessels, lipid.

19. Neurotrophic keratopathy (reduced corneal sensation)

    • Poor healing because the cornea doesn’t “feel” damage; vessels can grow; lipid may follow.

20. Systemic lipid disorders (e.g., severe hypercholesterolemia, rare enzyme defects)

    • High blood lipids or unusual lipoproteins can encourage corneal lipid, sometimes even when vessels are not obvious (primary lipid keratopathy). Doctors also consider other corneal dystrophies that have cholesterol (for example, Schnyder corneal dystrophy) in the differential diagnosis.

Symptoms

1. Blurred or hazy vision – light can’t pass cleanly through lipid-laden areas.

2. Glare and halos – especially from oncoming headlights at night.

3. Light sensitivity (photophobia) – inflamed corneas dislike bright light.

4. Ghost images or double vision in one eye – irregular astigmatism from uneven corneal surface.

5. Reduced contrast – whites and grays look more “washed out.”

6. A visible white or yellow spot – often near new red vessels at the corneal edge.

7. Redness – from ongoing surface inflammation.

8. Soreness or pain – ranges from gritty or burning to sharp if there is ulceration.

9. Foreign-body sensation – feels like sand due to a rough surface.

10. Tearing or watery eye – reflex response to irritation.

11. Dryness – poor tear quality makes symptoms worse.

12. Reduced contact-lens comfort – lenses feel uncomfortable or intolerable.

13. Frequent “flare-ups” – episodes where the eye gets redder and more light-sensitive.

14. Slow visual recovery after blinking – because the tear film is unstable.

15. No symptoms at first – early lipid can be silent and found only during an eye exam.

Diagnostic tests

A) Physical exam

1. Visual acuity testing

   • What it is: Reading the eye chart.

   • Why it matters: Measures how much vision is affected by corneal haze, scarring, or irregular surface.

2. Pupil examination

   • What it is: Doctor checks pupil size and reactions to light.

   • Why it matters: Confirms that reduced vision is corneal (front of the eye) and not from nerve or retina.

3. External eye inspection (lids and conjunctiva)

   • What it is: Careful look at the eyelids, lashes, oil glands, and the white of the eye.

   • Why it matters: Finds blepharitis/rosacea, which can drive corneal inflammation and vessel growth.

4. Penlight corneal inspection

   • What it is: A quick hand-held light exam of the cornea.

   • Why it matters: Screens for obvious haze, yellow-white lipid, and new red vessels crossing the limbus.

B) Manual clinical tests

5. Slit-lamp biomicroscopy

   • What it is: The core microscope exam of the eye’s front.

   • Why it matters: Shows where lipid is, how deep, and how close it is to abnormal vessels. The doctor looks for foam cells, crystalline sparkle, and any active inflammation.

6. Fluorescein staining of the cornea

   • What it is: A safe dye placed on the eye surface and viewed under blue light.

   • Why it matters: Highlights surface defects, ulcers, and tear film problems that drive vessel growth and lipid.

7. Corneal sensitivity testing (Cochet-Bonnet esthesiometer)

   • What it is: A fine nylon filament touches the cornea to see how well it can feel.

   • Why it matters: Low sensation suggests neurotrophic keratopathy, a risk for persistent defects and vessels.

8. Schirmer tear test

   • What it is: A paper strip under the lower lid measures tear production.

   • Why it matters: Dry eye worsens inflammation and can prolong healing, raising the chance of vessels and lipid.

9. Tear break-up time (TBUT)

   • What it is: After dye, the doctor times how quickly the tear film breaks up.

   • Why it matters: Unstable tears irritate the cornea and can sustain inflammation.

10. Goldmann applanation tonometry (eye pressure)

    • What it is: A gentle measurement of intraocular pressure (IOP).

    • Why it matters: Inflammation and steroid treatment (sometimes needed for the cornea) can raise IOP, so monitoring is important.

C) Laboratory and pathological tests

11. Corneal scraping for Gram stain and bacterial culture

    • What it is: A tiny sample from an active ulcer is examined and cultured.

    • Why it matters: Identifies bacterial infection that must be eradicated to stop vessels and lipid from progressing.

12. KOH prep and fungal culture

    • What it is: A quick microscope prep and special culture to detect fungi.

    • Why it matters: Fungal keratitis is often deep and chronic—a known trigger for vessel growth and later lipid.

13. PCR testing (HSV/VZV/Acanthamoeba) on corneal samples when indicated

    • What it is: DNA testing for specific germs.

    • Why it matters: Accurate diagnosis of viral or amoebic infection guides targeted therapy, reducing inflammation and future lipid.

14. Fasting serum lipid profile (cholesterol, LDL, HDL, triglycerides; often apolipoproteins)

    • What it is: A blood test for fat levels.

    • Why it matters: Finds systemic lipid disorders that can feed corneal lipid, especially when vessels are present or primary lipid keratopathy is suspected.

15. Syphilis serology (e.g., RPR/VDRL with confirmatory treponemal test)

    • What it is: Blood tests for syphilis, a cause of interstitial keratitis.

    • Why it matters: Treating the root cause (e.g., syphilis) helps stop active inflammation and future lipid deposition.

D) Electrodiagnostic tests

16. Visual evoked potential (VEP)

    • What it is: Measures electrical responses from the visual cortex to a visual pattern.

    • Why it matters: If vision is worse than the cornea alone explains, VEP checks whether the optic nerve/brain pathway is also involved.

17. Electrooculography (EOG)

    • What it is: Records electrical changes across the eye with light/dark cycles.

    • Why it matters: Not routine for lipid keratopathy; occasionally used to exclude retinal pigment epithelium problems when the diagnosis is unclear.

E) Imaging tests

18. Anterior-segment optical coherence tomography (AS-OCT)

    • What it is: A non-contact scan that maps the cornea in micron detail.

    • Why it matters: Shows how deep the lipid sits, the thickness of the cornea, and scarring—useful for planning and for before-and-after comparisons.

19. Corneal angiography (fluorescein or indocyanine green) or anterior-segment OCT-angiography

    • What it is: Imaging that maps corneal blood vessels.

    • Why it matters: Identifies leaking, active vessels that are feeding the lipid—key for deciding on anti-vascular treatments.

20. In vivo confocal microscopy

    • What it is: A microscope that images cells inside the living cornea.

    • Why it matters: Can show lipid-laden cells (foam cells), crystals, nerve damage, and microbes—all of which guide treatment.

Non-pharmacological treatments

Important: The single most important strategy is to treat the cause and shut down the abnormal corneal vessels so new lipid stops leaking in. Vision then stabilizes, and some deposits fade slowly. PMC

1. Aggressive lubrication with preservative-free tears – keeps the surface calm, lowers friction and inflammation triggers; use frequently during the day.

2. Lid hygiene + warm compresses – treats blepharitis/meibomian disease (a common driver of surface inflammation); purpose is to reduce vessel-stimulating cytokines from the lids.

3. Stop contact lens over-wear – resting the cornea reduces hypoxia-driven vessel growth; later consider refitting with high-oxygen materials only if medically safe. EyeWiki

4. Scleral lens for vision – vaults over the deposit with a fluid reservoir, improving optics without rubbing the cornea; purpose is visual rehab while disease control proceeds.

5. UV-blocking eyewear – lowers UV-mediated inflammation that can sustain neovascularization.

6. Treat dry eye contributors – plugs or moisture chamber glasses when indicated; calmer surface → fewer pro-angiogenic signals.

7. Control systemic risk factors – e.g., manage rosacea, autoimmune disease, or lipid disorders when present; less upstream inflammation = fewer vessels.

8. Avoid eye rubbing – micro-trauma perpetuates inflammation and vascular cues.

9. Cold compress during flares – symptomatic relief of hyperemia/irritation.

10. Nutritional pattern (heart-healthy, anti-inflammatory) – supports vascular health; not a cure for LK but good for overall ocular/systemic health (details below).

11. Targeted feeder-vessel laser photocoagulation (argon/yellow/diode) – office procedure to seal pathological vessels; often combined with anti-VEGF or steroids. JournalAgent

12. Fine-needle diathermy (FND) – a micro-cautery technique to coagulate individual corneal vessels; effective adjunct before grafts and for stubborn neovascularization. PubMedIOVS

13. Angiography-guided vessel occlusion – dye or OCT-A mapping improves precision of FND/laser targeting. AAO Journal

14. Photodynamic therapy (PDT) with verteporfin – light-activated drug closes abnormal vessels with selective photothrombosis; useful for diffuse, deep, or laser-resistant networks. PubMedAjo

15. Radiofrequency diathermy – a slit-lamp procedure using a heated micro-tip to close vessels feeding the lipid plaque; promising in small case series. The Open Ophthalmology JournalPubMed

16. Mitomycin intravascular chemo-embolization (MICE) – emerging technique injecting mitomycin-C into feeder vessels; early reports suggest it can stop flow (specialist centers only). EyeWiki

17. Protective eye shields in risky settings – prevents micro-trauma and drying (e.g., CPAP airflow, high-wind activities).

18. Short-term bandage soft lens (only if your doctor advises) – comfort during epithelial healing; used cautiously because lenses themselves can worsen hypoxia if overused.

19. Vision rehabilitation – tinted lenses/filters reduce glare; low-vision aids help reading if deposits are central.

20. Watchful waiting after vessel shutdown – once leakage stops, some lipid gradually clears; patience avoids unnecessary surgery.

Drug treatments

Doses are typical starting points for adults; your cornea specialist will tailor them to your case.

1. Topical corticosteroids (e.g., prednisolone acetate 1% q.i.d. then taper; or loteprednol for a safer profile). Purpose: calm inflammation that drives vessel growth. Mechanism: suppresses cytokines/VEGF up-stream. Side effects: pressure rise, cataract risk with prolonged use.

2. Anti-VEGF therapy (bevacizumab) — topical 1% drops, subconjunctival, or intra/stromal injections used off-label to reduce corneal neovascularization; results vary, and repeated dosing may be needed. Side effects: epithelial toxicity (topical), irritation, rare infection with injections. Evidence is growing but mixed in high-risk graft settings. PMCAdvances

3. Oral doxycycline 50 mg twice daily (short courses) — Purpose: MMP inhibition and anti-inflammatory effect on ocular surface. Mechanism: reduces matrix breakdown and vessel stimuli. Side effects: photosensitivity, GI upset; avoid in pregnancy.

4. Topical cyclosporine 0.05–0.1% b.i.d. — Purpose: steroid-sparing control of chronic surface inflammation. Mechanism: calcineurin inhibition reduces T-cell activity. Side effects: burning on instillation.

5. Topical tacrolimus 0.03–0.1% (compounded) — similar purpose/mechanism to cyclosporine; helpful in immune-mediated keratitis; monitor for irritation.

6. Antiviral therapy for herpetic disease (e.g., valacyclovir 500 mg t.i.d. for active disease, then 500 mg daily prophylaxis months if recurrent). Purpose: prevent reactivations that rekindle vessels. Side effects: headache, GI upset; dose-adjust in renal disease.

7. Antibacterials (fluoroquinolone drops) for active bacterial keratitis until healed (stops the trigger).

8. Antifungals (e.g., natamycin 5% drops) for filamentous fungal keratitis where indicated.

9. Penicillin G (IV) for syphilitic interstitial keratitis, per infectious-disease guidelines, to eliminate the driver disease.

10. Systemic statins if true systemic dyslipidemia is present — Purpose: treat body-wide lipid abnormalities; Note: most lipid keratopathy is local and not caused by high blood cholesterol, so statins are used for cardiovascular indications, not as primary LK therapy. EyeWiki

---

Dietary / molecular and supportive supplements

These do not dissolve corneal lipid by themselves; they support ocular surface and general vascular health. Use within safe daily limits and discuss with your physician, especially if you take anticoagulants or have chronic disease. EyeWiki

1. Omega-3 fatty acids (fish oil) — 1–2 g/day EPA+DHA supports meibomian oil quality and surface calm.

2. Flaxseed oil (ALA) — 1–2 g/day if fish oil is not tolerated; similar anti-inflammatory intent.

3. Vitamin D — replete if deficient (commonly 800–2000 IU/day) to modulate immunity.

4. Vitamin A — stick to RDA (700–900 mcg RAE/day); supports epithelial health; avoid excess.

5. Vitamin C — 500–1000 mg/day aids collagen cross-linking and wound healing.

6. Vitamin E — 100–200 IU/day antioxidant support; avoid high doses with anticoagulants.

7. Zinc (10–20 mg/day) with copper 1–2 mg/day if supplementing longer term; cofactor roles in healing.

8. Curcumin — anti-inflammatory polyphenol; consider 500–1000 mg/day standardized extract; evidence in corneal NV is preclinical.

9. Green-tea extract (EGCG) — antioxidant/anti-angiogenic signals in lab models; typical 200–400 mg/day.

10. Resveratrol — 100–250 mg/day; lab data suggest anti-angiogenic pathways; human corneal data limited.

11. Quercetin — 250–500 mg/day; anti-inflammatory; clinical data on LK lacking.

12. Hyaluronic acid ophthalmic drops — 0.15–0.3% for comfort and epithelial support (OTC).

13. Carboxymethylcellulose/glycerin tears — frequent use reduces frictional inflammation.

14. L-carnitine — 500–1000 mg/day; general mitochondrial support; ocular data limited.

15. Probiotic-rich foods (yogurt/kefir) — gut-immune balance; indirect support only.

Regenerative / stem-cell–adjacent” therapies

These help the ocular surface heal and quiet inflammation; they don’t directly dissolve lipid but may reduce the triggers that keep vessels active.

1. Topical cyclosporine 0.05–0.1% b.i.d. — Function: immunomodulation of T-cell–driven surface inflammation; Mechanism: calcineurin blockade; Note: useful when steroid-sparing is desired.

2. Topical tacrolimus 0.03–0.1% — Function: stronger calcineurin inhibition than cyclosporine in some cases; Mechanism: dampens immune signals sustaining pannus.

3. Lifitegrast 5% b.i.d. — Function: reduces inflammatory cell adhesion (LFA-1/ICAM-1 blockade) in chronic ocular surface inflammation.

4. Autologous serum tears (20–50%) q.i.d. — Function: growth factors and vitamins support epithelial healing; Mechanism: mimics natural tear nutrients; prepared from your own blood.

5. Platelet-rich plasma eye drops — Function: high platelet growth factors aid chronic epithelial defects; Mechanism: regenerative trophic support.

6. Cenegermin (rhNGF 0.002%) q6h for 8 weeks (for neurotrophic keratitis) — Function: heals denervated cornea; Mechanism: nerve growth factor promotes epithelial recovery; indirectly reduces stimulus for vessels.

Surgical options

1. Laser photocoagulation of feeder vessels – argon/yellow/diode lasers seal visible vessels to stop lipid leakage; often combined with anti-VEGF or steroids to reduce recurrence. JournalAgent

2. Fine-needle diathermy (FND) – a microcautery pin applied under slit-lamp guidance to coagulate individual pathologic vessels. Helpful before corneal grafting and in stubborn cases. PubMedLippincott Journals

3. Photodynamic therapy (PDT, verteporfin) – drug is infused or applied, then activated by a specific light to selectively shut down corneal vessels, especially deeper plexuses not amenable to laser. PubMedAjo

4. Lamellar keratoplasty (e.g., DALK/ALTK) – partial-thickness corneal transplant to replace scarred/lipid-laden stroma while keeping your own endothelium; preferred when feasible because rejection risk is lower than full-thickness.

5. Penetrating keratoplasty (full-thickness graft) – reserved for dense, central scarring or failed lamellar surgery. Important: surgeons try to clear/close vessels first, because active vascularization raises graft rejection risk. Anti-VEGF can be considered as an adjunct, though large trials show mixed significance. PMC

Prevention tips

1. Treat any keratitis quickly (viral, bacterial, fungal).

2. Do not over-wear contact lenses; never sleep in lenses unless they’re approved and your doctor says it’s safe. EyeWiki

3. Keep lids healthy: warm compress + lid hygiene if you have blepharitis/rosacea.

4. Wear UV-blocking sunglasses outdoors.

5. Avoid eye rubbing.

6. Use preservative-free tears if you have dryness.

7. Protect your eyes at work/sports (shields/goggles).

8. Control systemic risks (lipids when abnormal, autoimmune disease, diabetes).

9. Quit smoking (angiogenesis and healing are worse with tobacco).

10. Keep follow-ups after any corneal infection, injury, or surgery.

---

When to see a doctor urgently

• New eye pain, light sensitivity, or rapidly worsening redness.

• Sudden drop in vision, halos around lights, or large new glare.

• A new pale spot on the cornea or visible “red lines” growing into it.

• Any eye infection symptoms while wearing contact lenses.

• Before and after corneal surgery (to catch vessels early).

What to eat and what to avoid”

Note: Most lipid keratopathy is local and vessel-related, not from high cholesterol in the blood. Even so, a heart-healthy, anti-inflammatory pattern supports overall vascular health and the ocular surface. EyeWiki

Emphasize:

1. Oily fish (salmon/sardine) 2–3×/week for omega-3s.

2. Extra-virgin olive oil as main fat.

3. Colorful vegetables and leafy greens daily.

4. Citrus/berries (vitamin C) most days.

5. Nuts/seeds in small handfuls.

6. Whole grains over refined grains.

7. Fermented dairy/yogurt for probiotics.

8. Adequate hydration.

9. Spices with anti-inflammatory profiles (turmeric/ginger) in cooking.

10. If a clinician finds high blood lipids, follow a Mediterranean-style plan and medical therapy.

Limit/avoid: industrial trans fats, ultra-processed snacks, frequent deep-fried foods, excessive added sugars, and heavy alcohol—these worsen systemic inflammation and vascular health.

FAQs

1) Is lipid keratopathy dangerous?
It threatens clarity, not the structural strength of the eye. The main risk is vision decline from scattering and irregular astigmatism.

2) Will it go away on its own?
If feeder vessels are closed and inflammation is quiet, some lipid can fade slowly over months to years. Dense plaques may persist and sometimes need lamellar or full-thickness transplant.

3) Is it the same as corneal arcus?
No. Arcus is a ring at the very edge of the cornea and usually harmless; lipid keratopathy is focal/patchy inside the cornea and most often sits next to abnormal vessels. PMC

4) Do I need to check my cholesterol?
Often yes as a screen, but remember primary LK usually has normal lipids. Treat systemic dyslipidemia if present for cardiovascular health. EyeWiki

5) Can eye drops dissolve the fat?
No drop literally dissolves lipid. The strategy is to stop the leak (treat vessels and the cause) and let the eye clear slowly.

6) Are anti-VEGF drops or injections safe?
They are used off-label for corneal vessels. Many clinicians report benefit; trials in high-risk grafts show trends but mixed statistical significance. Your surgeon will weigh risks/benefits. PMCAdvances

7) What about lasers?
Laser photocoagulation can precisely close vessels; success improves when angiography guides the target. Recurrences can happen; combination therapy helps. JournalAgentAAO Journal

8) What is fine-needle diathermy?
A micro-cautery pin coagulates individual vessels under topical anesthesia. It’s effective and inexpensive in experienced hands. IOVS

9) Photodynamic therapy sounds intense—when is it used?
PDT is handy for deeper, diffuse networks that laser can’t reach well. It selectively shuts those vessels using a light-activated drug. PubMed

10) Could lipid keratopathy return after a corneal transplant?
Yes—if vessels persist or recur, lipid and scarring can come back, which is why doctors aim to silence vessels first. PMC

11) Can I keep wearing contact lenses?
Often you’ll pause during treatment. Later, some patients do well with scleral lenses for optics, but safety depends on your cornea and vessel status.

12) Are nutritional supplements required?
No—they’re optional supports. Focus first on closing vessels, controlling inflammation, and addressing the cause.

13) Is it contagious?
No. The lipid itself isn’t an infection. But some triggers (like herpetic keratitis) need proper antiviral care.

14) How do doctors decide between lamellar and full-thickness grafts?
Based on depth/location of opacity, endothelial health, and risk of rejection. Keeping your own endothelium (lamellar) is preferred when feasible.

15) What kind of follow-up do I need?
Early on, visits are frequent to track vessels (often with photos or AS-OCTA). Once stable, follow-ups space out. MDPI
