Keratoconus
Progressive thinning and bulging of the cornea that distorts vision. Berg-Feinfield offers the full care continuum — from early topographic monitoring through cross-linking and transplantation for advanced disease.

Berg-Feinfield's cornea program is led by Dr. Bonnie Sklar — fellowship-trained at Duke University Eye Center — offering the full spectrum of corneal diagnosis, medical management, and surgical care across five Los Angeles area locations.
What Is the Cornea?
The cornea is the clear, dome-shaped front surface of the eye — the window through which light enters. It performs roughly two-thirds of the eye's total focusing power, bending incoming light so it lands precisely on the retina at the back of the eye.
Despite being only about half a millimeter thick, the cornea is a precisely organized structure made up of five distinct layers — each with a specific function. When any layer is damaged, diseased, or fails, vision suffers in ways that glasses or contact lenses often cannot fully correct.
The five layers are the epithelium (outer surface), Bowman's layer, the stroma (the thickest layer, about 90% of corneal thickness), Descemet's membrane, and the endothelium (inner pump cells). Because many conditions affect specific layers, modern transplant surgery can now replace only the diseased layer rather than the entire cornea.
Explore Corneal ConditionsCorneal Conditions We Treat
From early keratoconus monitoring to advanced corneal disease, Berg-Feinfield's cornea program covers every stage — all under the care of a fellowship-trained specialist.
Fuchs' Endothelial Dystrophy
A hereditary condition that gradually destroys the cells your cornea needs to stay clear. Managed with drops in early stages; treated with DMEK surgery — the least invasive transplant option — when advanced.
Learn more →Pterygium — Surfer's Eye
A non-cancerous growth of tissue that extends from the white of the eye onto the cornea. Common in sun-intensive environments like Los Angeles. Removed with conjunctival autograft surgery when growth or vision is affected.
Learn more →Corneal Ulcer & Infectious Keratitis
A vision-threatening infection of the cornea requiring same-day evaluation. Can be caused by bacteria, viruses, fungi, or Acanthamoeba. Contact lens wearers are at highest risk — call us immediately if you have symptoms.
Learn more →Corneal Treatments
Advanced, layer-specific care — from the newest cross-linking therapy for keratoconus to the full range of modern corneal transplantation.
Epioxa Epi-On Corneal Cross-Linking
The first FDA-approved epi-on cross-linking (CXL) therapy for keratoconus, approved in 2025. No epithelium removal, no open wound, and significantly faster recovery than standard CXL. Berg-Feinfield is the first practice in Los Angeles to offer Epioxa.
Learn more →Corneal Transplant — DMEK, DSEK & PKP
Dr. Sklar performs the full range of modern corneal transplantation — from minimally invasive DMEK for Fuchs' dystrophy to full-thickness PKP for advanced keratoconus and corneal scarring.

Corneal disease covers a wide range of conditions — from progressive thinning (keratoconus) and cell-layer failure (Fuchs' dystrophy) to surface growths (pterygium) and infections (corneal ulcers). A fellowship-trained cornea specialist has the diagnostic tools and surgical training to manage the full spectrum.
Epioxa is the first FDA-approved epi-on cross-linking (CXL) therapy for keratoconus. Because it does not require removal of the epithelium, there is no open wound and recovery is significantly faster than standard CXL. Berg-Feinfield is the first practice in Los Angeles to offer Epioxa.
Because many corneal conditions affect specific layers, modern transplant surgery can often replace only the diseased layer rather than the entire cornea. Dr. Sklar performs the full range — from minimally invasive DMEK for Fuchs' dystrophy to full-thickness PKP for advanced keratoconus and corneal scarring.
Yes. A corneal ulcer or infectious keratitis is a vision-threatening infection that requires same-day evaluation. It can be caused by bacteria, viruses, fungi, or Acanthamoeba, and contact lens wearers are at highest risk. If you have a painful red eye, a white spot on your cornea, or sudden vision change, call us immediately at 866-2-SEE-FAR.
