Keratoconus is a condition where the cornea develops an irregular shape instead of its normal round one. The cornea is the clear frontal tissue in our eyes where contact lenses rest when we wear them.
This irregular shape of the cornea causes irregular amounts of astigmatism and distorted vision that is difficult to correct with glasses. Very commonly patients find their glasses prescription is not helping or need more frequent prescription changes.
Keratoconus tends to be a progressive condition that may lead to corneal transplant eventually if the cornea is damaged, but the prognosis may vary for each individual patient.
Rigid gas permeable contact lenses provide better vision for the patient than glasses and end up being the habitual method for vision improvement or correction.
Corneal cross linking is a therapy that uses UV light to strengthen the cornea and aims to halt the progression of keratoconus.
It is very important that keratoconus patients take proper care of their lenses and manage other conditions like ocular allergies which may aggravate their condition.
