A recent study has revealed that the treatment of keratoconus, a condition that threatens vision, can worsen even after treatment.
About Keratoconus:
It is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped.
This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision.
Keratoconus often starts when people are in their late teens to early 20s.
The vision symptoms slowly get worse over a period of about 10 to 20 years.
It often affects both eyes and can lead to very different vision between the two eyes.
Symptoms can differ in each eye, and they can change over time.
Treatment and Prevention:
There is no known prevention for keratoconus.
Early stages can be treated with glasses, but with progression of the disease into late childhood and early adulthood, corneal transplantation may be needed to restore sight.
Corneal collagen cross-linking is a procedure designed to stop the progression of keratoconus or slow it down.
