Metabolic Keratopathy

Metabolic keratopathy means your cornea (the clear front window of the eye) is getting sick because abnormal substances build up inside it, or because the cornea’s normal chemistry is disturbed. Those substances can be calcium, fats (lipids), copper, crystals, or even certain medicines that collect in the corneal layers. Over time, these deposits make the cornea lose its clear, glass-like look, so light can’t pass through cleanly, and vision becomes hazy or painful.

Doctors use “metabolic” here to point at body chemistry problems (inherited or acquired), blood chemistry changes (like high calcium or fats), or drug-related changes that show up in the cornea. Classic examples include calcium bands on the cornea (band keratopathy), fat deposits linked to abnormal lipid handling (lipid keratopathy), whorl-shaped lines from certain drugs or Fabry disease (cornea verticillata), and copper rings in Wilson disease. EyeWiki+1PMCNCBI

• The cornea is the clear dome at the very front of the eye.

• It has layers: a thin skin (epithelium), a tough shield (Bowman’s layer), the thick middle (stroma), a thin membrane (Descemet’s), and an inner lining (endothelium).

• It has no blood vessels, so anything that reaches it diffuses in through tears, the fluid in the front of the eye, or grows in via abnormal blood vessels. That is why chemistry problems in the body or drug molecules can leave visible deposits in the cornea.

Types of metabolic keratopathy

Each “type” below is explained in plain English with a quick real-world example.

1. Calcium deposition (“band keratopathy”)
   A gray-white horizontal band of calcium forms across the cornea, usually where the eyelids don’t cover the eye (the inter-palpebral zone). It can be linked to high calcium or phosphate in the blood, kidney disease, or chronic? eye infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation?. The surface can feel rough and scratchy. EyeWikiCleveland Clinic

2. Lipid deposition (“lipid keratopathy”)
   Fat (lipid) material collects in the corneal stroma (the thick middle), often after new, abnormal blood vessels have grown into the cornea. These vessels leak fats into the clear tissue, turning it cloudy or yellow-white and reducing vision. Primary (inherited) forms are rare; secondary forms (after infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation? or vessels) are much more common. PMCEyeWiki

3. Whorl lines (“cornea verticillata” / “vortex keratopathy”)
   Fine, whorl-shaped lines in the corneal surface layers. They can appear in Fabry disease (an inherited storage disorder) or after certain medicines (e.g., amiodarone, chloroquine/hydroxychloroquine, indomethacin, phenothiazines). They usually don’t hurt vision and may fade if the drug is stopped. NCBIEyeWikiPMC

4. Copper ring (Kayser–Fleischer ring in Wilson disease)
   A golden–green ring at the corneal edge from copper deposited in Descemet’s membrane due to a copper-handling disorder. It is a key sign of Wilson disease and needs systemic? evaluation and treatment. NCBI

5. Cystine crystals (cystinosis)
   Sparkling, needle-like crystals in all corneal layers due to cystine buildup from a rare lysosomal storage disease. Light hurts (photophobia) and vision blurs without treatment. EyeWikiCystinosis Research Network

6. Tyrosine-related surface injury (tyrosinemia type II / Richner–Hanhart)
   Painful pseudodendritic (branch-like) keratitis, redness, tearing, and sometimes scarring in infants/children with very high tyrosine levels. Treating the underlying amino-acid problem helps the eye heal. Wadsworth Center

7. Glycosaminoglycan storage (mucopolysaccharidoses, e.g., MPS I and VI)
   Cloudy corneas from widespread storage of GAGs in the stroma. Severity varies by subtype and may require corneal transplant when vision is badly affected. PMC+1

8. Cholesterol?-related clouding (LCAT deficiency, “fish-eye disease”)
   Diffuse, dot-like cholesterol? opacities develop over years due to abnormal HDL metabolism (LCAT enzyme problem). Vision can slowly decline. MedlinePlus+1

9. Oxalate crystals (primary hyperoxaluria / systemic? oxalosis)
   Calcium oxalate crystals can lodge in the cornea (and other eye tissues) when the body makes too much oxalate. This is rare but sight-threatening without systemic? treatment. PubMed

10. Urate crystals (gout)
    Very uncommon, but uric acid crystals can deposit in the cornea and cause irritation or even an ulcer? at the edge of the cornea. Managing hyperuricemia helps. PubMed

11. Drug-induced deposits beyond whorl lines
    A wide range of medicines can leave visible corneal deposits (by causing a cellular “lipidosis”), including amiodarone, antimalarials, tamoxifen, chlorpromazine, clofazimine, and others. Patterns vary by layer (surface/stroma/endothelium), dose, and duration. PMC

12. Diabetic keratopathy (nerve and surface healing problems)
    insulin? is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">Diabetes? can reduce corneal sensation, slow healing, and increase risk of erosions and ulcers. This is a metabolic effect on the cornea’s nerves and epithelium. PMC

13. Vitamin A deficiency (xerophthalmia / keratomalacia)
    Severe Vitamin A lack makes the corneal surface dry and fragile, leading to ulcers, softening (keratomalacia), and scarring if not treated quickly. World Health OrganizationNCBI

14. Paraproteinemic (monoclonal protein–related) crystalline keratopathy
    In MGUS or multiple myeloma, abnormal immunoglobulin light chains can crystallize in the cornea. Sometimes the eye signs are the first clue to an underlying blood disorder. NCBI

15. Schnyder corneal dystrophy (autosomal dominant lipid disorder)
    A genetic problem in UBIAD1 causes cholesterol?/phospholipid buildup in the cornea, sometimes with visible crystals, central haze, and reduced vision. EyeWiki

16. Secondary lipid keratopathy after corneal neovascularization
    Any condition that makes new vessels grow into the cornea (chronic? infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation?, infections, trauma, contact lens overuse) can later cause lipid deposition around those vessels. PMC

17. End-stage kidney disease and mineral imbalance
    People with ESRD can have band keratopathy more often, likely from calcium/phosphate imbalance and local tear chemistry changes on the ocular surface. PMC

18. Hyperparathyroidism / hypercalcemia
    High calcium states encourage calcium–phosphate precipitation in the cornea, producing calcific bands. Treating the metabolic cause helps prevent recurrence. EyeWiki

19. Phosphate-containing eyedrops on a damaged surface
    Some phosphate-buffered drops can promote calcium–phosphate deposition in vulnerable corneas (e.g., after ulcers or surgery), speeding band keratopathy. EyeWikiJAMA Network

20. Bietti crystalline dystrophy (rare)
    Primarily a retinal disease with lipid crystals, but limbal corneal crystals are described in some patients. EyeWiki

Common symptoms

1. Blurry vision (things look foggy or smeared).

2. Glare from bright lights (car headlights feel dazzling).

3. Halos or rainbow rings around lights.

4. Eye pain? or soreness, especially with surface defects.

5. Light sensitivity (photophobia).

6. Redness of the white of the eye.

7. Tearing or watery eyes.

8. Gritty/foreign-body feeling (like sand in the eye).

9. Dryness or burning.

10. Recurrent erosions (repeated surface scratches on waking).

11. Slow healing after minor abrasions (common in insulin? is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">diabetes?).

12. Decreased corneal feeling (numb surface; you may notice less pain? than expected).

13. Visible spots or rings (e.g., a gray band, a copper ring, or sparkling crystals).

14. Reduced contrast (colors and details seem dull).

15. Contact lens intolerance (lenses become uncomfortable).

Note: symptoms can be mild at first; some drug- or copper-related changes may cause little to no early visual trouble even though the signs are present.

Diagnostic tests

A) Physical exam

1. History & medication review
   The doctor asks about systemic? diseases (kidney, liver, lipid disorders, insulin? is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।" data-rx-term="diabetes" data-rx-definition="Diabetes is a condition where blood sugar stays too high because insulin is low or not working well. সহজ বাংলা: রক্তে চিনি বেশি থাকার রোগ।">diabetes?), diet, vitamins, and medications (e.g., amiodarone, chloroquine, tamoxifen) that can leave corneal deposits. This step often gives the first big clue. PMC

2. Visual acuity and pinhole test
   Reading the chart with and without a pinhole shows how much the cornea’s clarity affects vision (pinhole can bypass blur from surface irregularity).

3. External inspection under bright/oblique light
   The clinician looks for obvious bands, rings, or sparkles, and skin signs that hint at systemic? diseases (e.g., angiokeratomas in Fabry, palmar lesions in tyrosinemia II). NCBIWadsworth Center

4. Slit-lamp biomicroscopy
   A special microscope with a thin light beam lets the examiner localize deposits by layer (surface vs stroma vs Descemet’s). For example, a Kayser–Fleischer ring sits in Descemet’s membrane; cornea verticillata is superficial. NCBI

B) Manual/bedside ocular surface tests

5. Fluorescein dye staining
   A yellow dye highlights surface defects, erosions, or pseudodendritic patterns seen in tyrosinemia II (helps distinguish from herpes). Wadsworth Center

6. Schirmer test
   A small paper strip measures baseline tear production. Poor tears worsen surface damage in many metabolic conditions.

7. Tear break-up time (TBUT)
   A little dye plus a blue light shows how fast tears break into dry spots. Rapid break-up means unstable tear film, which aggravates pain? and glare.

8. Corneal esthesiometry (sensation test)
   A thin nylon filament touches the cornea to see how well you feel it. Reduced feeling suggests diabetic corneal numbness?, tingling, or weakness?. সহজ বাংলা: স্নায়ুর ক্ষতি/সমস্যা।" data-rx-term="neuropathy" data-rx-definition="Neuropathy means nerve damage or irritation causing pain, numbness, tingling, or weakness. সহজ বাংলা: স্নায়ুর ক্ষতি/সমস্যা।">neuropathy? or neurotrophic keratopathy. PMC

C) Laboratory & pathological tests

9. Mineral panel: serum calcium, phosphate, ± parathyroid hormone (PTH)
   High calcium/phosphate favors calcific band keratopathy. PTH helps sort the cause (e.g., hyperparathyroidism). EyeWiki

10. Kidney function: creatinine, eGFR
    Kidney failure (ESRD) shifts calcium/phosphate balance and raises band keratopathy risk. PMC

11. Lipid profile (total cholesterol, LDL, HDL, triglycerides)
    High lipids can accompany lipid keratopathy and certain genetic lipid disorders. PMC

12. Copper studies (serum ceruloplasmin + 24-hour urinary copper)
    Abnormal results support Wilson disease when a Kayser–Fleischer ring is seen. NCBI

13. Leukocyte cystine or corneal crystal analysis
    Elevated cystine in white blood cells confirms cystinosis; crystals can also be typed if tissue is sampled. EyeWiki

14. Plasma amino acids (tyrosine level)
    Very high tyrosine supports tyrosinemia type II in a patient with pseudodendritic keratitis. MDEdge

15. Urinary glycosaminoglycans (GAGs) ± enzyme/genetic panel
    Elevated GAGs suggest an MPS subtype when corneal clouding is present. PMC

16. LCAT activity and HDL cholesterol
    Low LCAT activity with very low HDL fits LCAT deficiency (“fish-eye disease”) when the cornea is diffusely cloudy. MedlinePlus

D) Electrodiagnostic tests

17. Electroretinography (ERG)
    Measures retinal function. Some metabolic diseases affect both cornea and retina; ERG helps explain vision loss that’s not purely corneal.

18. Visual evoked potentials (VEP)
    Checks the optic pathway when patients report vision loss out of proportion to corneal findings (helpful in systemic storage diseases).

These electrical tests aren’t needed for everyone, but they’re useful when metabolic diseases affect multiple eye structures.

E) Imaging of the front of the eye

19. Anterior segment OCT (AS-OCT)
    A cross-section scan showing the layer and depth of deposits (e.g., calcium band thickness, lipid location). This helps plan treatment.

20. Specular microscopy or in-vivo confocal microscopy
    Specular images the endothelium (the inner cell layer); confocal shows cell-level detail of crystals or lipids (e.g., urate or oxalate crystals, immunoglobulin deposits). These tools document and track change over time. Lippincott Journals

Non-pharmacological treatments

1. Preservative-free lubricating drops frequently
   Purpose: Keep the corneal surface smooth and comfortable.
   Mechanism: Adds a wet, protective layer to reduce friction and dilute irritating tear chemicals.

2. Nighttime lubricating gel/ointment
   Purpose: Prevent morning pain and blur from overnight drying or swelling.
   Mechanism: Thick layer slows evaporation and cushions the epithelium while you sleep.

3. Warm compresses + lid hygiene
   Purpose: Stabilize the oily part of tears (meibum) so tears last longer.
   Mechanism: Heat melts thickened oil; gentle cleaning removes crusts/biofilm that inflame the surface.

4. Moisture-chamber glasses / humidifier
   Purpose: Cut evaporation and wind exposure.
   Mechanism: Traps humidity around the eyes, keeping the corneal surface hydrated.

5. Scleral lenses / PROSE treatment
   Purpose: Optically smooths vision and bathes the cornea in a saline reservoir all day.
   Mechanism: A vaulting lens rests on the white of the eye (sclera), creating a constant fluid bath that protects and re-hydrates the cornea, often improving pain and function in severe ocular surface disease. PMC+1EyeWiki

6. Bandage soft contact lens (short-term)
   Purpose: Reduce pain during erosions or after procedures.
   Mechanism: Covers exposed nerve endings and shields healing epithelium.

7. Punctal plugs
   Purpose: Keep natural tears on the eye longer.
   Mechanism: Tiny plugs reduce drainage through tear ducts, raising tear volume.

8. UV-blocking sunglasses / hats
   Purpose: Lower light sensitivity and surface inflammation.
   Mechanism: Reduces UV and glare that can aggravate symptoms.

9. Treat the systemic driver (e.g., balance calcium, uric acid, copper; optimize blood sugar)
   Purpose: Stop new deposits and promote clearing.
   Mechanism: Corrects the chemistry that is feeding deposits like calcium, urate, or copper. PMCFrontiers

10. Stop or swap the offending medicine (if drug-related verticillata)
    Purpose: Prevent further whorl-like deposits.
    Mechanism: Removing the source allows gradual clearing as corneal cells renew. AAO Journal

11. Dietary therapy for specific disorders
    Purpose: For example, a low-tyrosine/low-phenylalanine diet in tyrosinemia type II can stop painful keratitis.
    Mechanism: Reduces toxic metabolites reaching the cornea. JRheum

15. Platelet-rich plasma (PRP) eye drops (specialist)
    Purpose: Speed up corneal epithelial healing in stubborn defects.
    Mechanism: Concentrated platelets release growth factors that drive repair. PMC+1

16. N-acetylcysteine (compounded) as a non-drug strategy to dissolve mucus
    Purpose: If thick mucous filaments are sticking to the cornea.
    Mechanism: Breaks disulfide bonds in mucins so filaments release and symptoms ease. EyeWiki

17. Hypertonic saline (5% drops / ointment)
    Purpose: Reduce superficial corneal swelling and morning blur.
    Mechanism: Draws excess water out of the cornea by osmosis. EyeWiki

18. Short “screen breaks” + blink training
    Purpose: Reduce evaporation and strain.
    Mechanism: Regular complete blinks refresh and spread tears.

19. Protective eyewear at work/sport
    Purpose: Prevent minor injuries that worsen the surface and trigger deposits.
    Mechanism: Physical barrier; fewer abrasions means fewer erosions.

20. Regular follow-up with an eye specialist
    Purpose: Track deposits, pressure, healing, and adjust care.
    Mechanism: Early tweaks prevent scarring and preserve sight.

Dietary / molecular and other supportive supplements

Talk to your doctor first, especially if pregnant, on blood thinners, or with kidney/liver disease.

1. Omega-3 fatty acids (EPA/DHA) — 1–2 g/day combined: calms surface inflammation; stabilizes the oily tear layer by altering meibum composition.

2. Vitamin A (within safe limits only) — supports goblet cells and epithelial growth; excess can harm—do not self-dose.

3. Vitamin D (if deficient) — helps immune balance; deficiency links to dry eye; dose per level.

4. Vitamin C (500–1000 mg/day) — co-factor for collagen; antioxidant support for healing.

5. L-carnitine (1–2 g/day) — cellular energy carrier; may reduce fatigue from systemic disease affecting ocular surface.

6. CoQ10 (100–200 mg/day) — mitochondrial support; antioxidant protection of corneal cells.

7. N-acetylcysteine oral (600 mg 1–2×/day) — antioxidant precursor to glutathione; supports tear quality (and topical NAC dissolves mucus). Review of Optometry

8. Zinc — only if your doctor prescribes for Wilson disease; do not self-start. disorders.eyes.arizona.edu

9. Copper restriction (dietary pattern, not a pill) — part of Wilson care under supervision. Frontiers

10. Low-purine pattern (cherries, hydration, less beer/organ meats) — supports uric-acid lowering therapy in gout. ScienceDirect

Regenerative / “hard immunity” / stem-cell-oriented therapies

1. Cenegermin (Oxervate®) — see above; biologic growth factor that repairs corneal nerve function and promotes long-lasting epithelial stability. OXERVATE® (cenegermin-bkbj)BioMed Central

2. Autologous serum tears (20–50%) — patient-derived biologic rich in EGF, vitamin A, TGF-β; used several times daily for months in severe disease; supports epithelial regrowth when standard therapy fails. AAO Journal

3. Platelet-rich plasma (PRP) eye drops — higher growth-factor levels than serum; often QID–hourly during active healing; helps persistent epithelial defects. PMCNature

4. Amniotic membrane (cryopreserved or dehydrated) as a biologic graft — placed in-office or OR to deliver growth factors and anti-scarring matrix; accelerates epithelial closure. (Surgical placement described below.)

5. Holoclar® (ex-vivo expanded autologous limbal epithelial cells, EU-approved) — a cell-based therapy for limbal stem cell deficiency; a sheet of your own lab-grown corneal cells is implanted to rebuild a healthy surface. (Specialized centers; EU availability.) European Medicines Agency (EMA)+1

6. Matrix-regenerating agents (RGTA®, e.g., Cacicol — EU/limited markets) — heparan-sulfate mimetic that protects growth factors in the wound bed; early studies and case series show faster pain relief and healing in difficult ulcers; not FDA-approved. PubMed

Surgical procedures

1. EDTA chelation (often with superficial keratectomy)
   What: The surgeon soaks the calcium band with an EDTA solution, gently loosens it, and lifts the calcium off; the epithelium is then allowed to regrow.
   Why: Smooths the surface and reduces glare/pain from calcific band keratopathy. PMC

2. Phototherapeutic keratectomy (PTK)
   What: An excimer laser polishes the superficial cornea, removing deposits/irregularities with micrometer precision.
   Why: Clears surface haze/bands and regularizes the cornea when EDTA or scraping is not enough or deposits recur. PMC

3. Superficial keratectomy (manual)
   What: Careful surgical scraping of superficial deposits or nodules.
   Why: Quick, effective in the office/OR for selected cases; success rates are high when done for the right indications. Frontiers

4. Amniotic membrane transplantation
   What: A biologic graft is placed on the cornea (often like a “contact lens” bandage).
   Why: Speeds healing, reduces inflammation/scarring in persistent defects.

5. Keratoplasty / Limbal stem cell transplant (e.g., SLET, CLET/Holoclar where available)
   What: Tissue (or lab-expanded stem cells) rebuilds the corneal surface or replaces scarred layers.
   Why: For advanced scarring or stem-cell loss that will not respond to other measures. European Medicines Agency (EMA)

Prevention tips

1. Keep systemic disease controlled (calcium, copper, uric acid, glucose).

2. Use preservative-free lubricants if you need frequent drops.

3. Blink fully and rest eyes during screen time (20-20-20 rule).

4. Hydrate and keep indoor humidity reasonable.

5. Sunglasses outdoors; avoid UV and wind.

6. Don’t sleep in contacts; follow strict hygiene.

7. Review medications with your doctor if verticillata appears.

8. Follow metabolic diet plans only with specialist guidance.

9. Treat eyelid disease (blepharitis/meibomian issues) early.

10. Keep regular eye checks, even if you feel okay.

When to see a doctor urgently

• Sudden pain, light sensitivity, or vision drop,

• A feeling of a cut or scratch that doesn’t settle in 24–48 hours,

• Halos, haze, or a new ring/band on the cornea,

• Non-healing surface after a week of careful care,

• Children with eye pain or light avoidance (tyrosinemia II can present this way),

• Systemic flare (e.g., worsening Wilson, gout) with new eye symptoms. JRheum

What to eat and what to avoid

• Eat more: water; vegetables and fruits (especially leafy greens, citrus for vitamin C); omega-3 sources (fatty fish, walnuts, flax); lean proteins; whole grains; and foods your metabolic specialist recommends for your specific disorder.

• Avoid or limit: excess alcohol (raises uric acid/dehydrates tears); very salty foods (can worsen dryness); ultra-processed snacks (promote inflammation); organ meats/anchovies/sardines (gout), high-copper foods (Wilson disease) only under specialist supervision; and maintain any low-tyrosine/phenylalanine plan if you have tyrosinemia type II.

FAQs

1) Is metabolic keratopathy an infection?
No. It’s chemistry-driven (metabolic), not a germ. Antibiotics are only used if there’s a surface break at risk of infection.

2) Can these deposits go away?
Often yes, slowly—if the cause is controlled (e.g., copper lowered in Wilson) and the surface is protected. Some need EDTA or PTK for a clean surface. PMC+1

3) Will I go blind?
Permanent vision loss is uncommon with timely care. The goal is to treat the cause, smooth the surface, and prevent scarring.

4) Why are mornings worse?
Overnight, eyelids are closed, evaporation drops, and the cornea can swell. Hypertonic saline at night or on waking often helps. EyeWiki

5) Are “whorl lines” from Fabry dangerous?
They signal a lysosomal storage issue; they rarely harm vision by themselves but point to a systemic disease that needs treatment (enzyme therapy). MDPI

6) Do I have to stop my heart medicine if it causes verticillata?
Never stop on your own. Your cardiologist may adjust therapy if the corneal changes are symptomatic. AAO Journal

7) Do serum or PRP drops really help?
In stubborn surface disease, studies show improved healing and symptoms in many patients, especially when standard drops fail. AAO JournalNature

8) What if my surface won’t heal?
Your doctor may use a bandage lens, amniotic membrane, cenegermin, or adjust systemic disease control. AAO Journal

9) Will EDTA or PTK fix it forever?
They clear what’s there, but recurrence can happen if the chemistry stays abnormal—hence the focus on systemic control plus surface protection. PMCLippincott Journals

10) Are scleral lenses safe?
When fitted and cared for properly, they’re very helpful and generally safe; follow cleaning and follow-up schedules closely. PMC

11) Can kids get metabolic keratopathy?
Yes—cystinosis and tyrosinemia II often present in childhood; early metabolic care prevents pain and scarring. PMCJRheum

12) Will diet alone cure me?
Diet supports treatment but rarely replaces it. Some conditions (like tyrosinemia II or Wilson disease) require strict medical plans and prescriptions. JRheumdisorders.eyes.arizona.edu

13) How long until I feel better?
Surface comfort can improve within days to weeks with lubrication and protection; deposit clearing may take weeks to months or require a procedure.

14) Is this contagious?
No.

15) How often should I follow up?
