Dr. Steven Suh interviews Dr. Kenneth Beckman about a debilitating, corneal thinning condition called keratoconus.
The incidence is approximately 1 in 2,000 individuals.
The major risk factors include atopic disease, Down’s Syndrome, some family history, floppy eyelid syndrome, and chronic eye rubbing.
- Initially patients may be asymptomatic
- Blurred or distorted vision from increasing nearsightedness and/or astigmatism
- Increased sensitivity to bright light and glare, which can cause problems with night driving
- A need for frequent changes in eyeglass prescriptions
- Sudden worsening or clouding of vision
Keratoconus can be diagnosed in the late teenage years and can worsen as time goes on.
Corneal topography is the main tool for diagnosis.
- Early: glasses, soft contact lenses, gas-permeable contacts, then specialty contacts called scleral lenses
- Later stages: traditional treatment has been corneal transplantation
- May have long recovery time in terms of improved vision
- Need numerous post-operative visits
- Will need a lifetime of steroid eye drops to help avoid rejection of the corneal graft
- Minor trauma can be dangerous to a post-corneal transplant eye
- May need another transplant in the future
- A relatively new, in-office procedure that can slow down the progression of the thinning and warping
- Cross-linking involves treating the cornea with eye drops containing riboflavin, a B-vitamin. After the cornea has been saturated with the riboflavin, the cornea is then treated with ultraviolet light.
- Procedure time is about one hour
- Eye drops are used for only a few weeks
- Goal is to catch keratoconus early to hopefully prevent, or at least delay, the need for a corneal transplant in the future
Cross-linking can also treat pellucid marginal degeneration and corneal thinning (or ectasia) after LASIK.
Here is the abstract for Dr. Beckman’s cross-linking article.
