Old belief: Males are predominantly affected by this disease. - Most modern studies with wide bases do not support this. Keratoconus affects both genders in a comparable manner.
Old belief : There is no known precipitating factor for keratoconus. - EYE RUBBING is thought to be a precipitating factor in about half the patients diagnosed with Keratoconus.
Old belief: Allergies are more commonly seen in this group of patients. This stands validated in several newer studies across the world including our own.

ICL for Keratoconus
Implantable contact lens (Staar Surgical, Switzerland) is another tool that is being used to help patients of keratoconus with large refractive errors.
This has shown itself to be a useful method in helping patients with advanced keratoconus and high myopia with cylindrical errors (usually in excess of -10 Diopters with upto -6Diopters cylinder)
It helps this class of patients improve the uncorrected visual acuity and allows use fo glasses for the small residual errors.
However, it may not take away all the visual deficits. As we now understand, it can not take care of the higher order aberrations and thus the quality of vision still remains less than ideal. However, it a great step from not being able to do anything at all.

Corneal Cross Linking for keratoconus
My research work on Corneal cross linking in Keratoconus has been published in the Indian Journal of Ophthlamology. It is available for free access at the following link:
