KERATOCONUS
Keratoconus is a degenerative disease that causes the cornea, the transparent layer of the eye, to become sharp, irregular and thin, and causes patients to gradually progress to myopia and astigmatism. Although the disease usually begins in adolescence, it becomes known in the 20s. It progresses between the ages of 20 and 40 and enters a stationary period after the age of 40. The shape of the cornea changes and vision level deteriorates. The quality of life of patients in this group decreases, and the quality of vision may be severely affected. Those with a family history of Keratoconus, especially individuals with a continuous increase in astigmatism and myopia, individuals with keratometric values close to 47.00 D in the Autorefractoceratometer measurement and an increase compared to previous findings, should be examined for keratoconus.
Keratoconus causes;
Although the cause of keratoconus disease is not fully known, genetic factors (predisposing to it) and mechanical traumas play the most important role in its development. Rubbing the eye increases intraocular pressure and may cause the disease to progress.
What are the symptoms of the disease?
Constant allergy or itching in the eye (mild eye irritation)
Inability to see clearly despite glasses
Increased sensitivity to light
Continuously progressive myopia and astigmatism
Eye glare
Two problems are essential in keratoconus.
1. Decrease in vision:To increase vision, HYBRID contact lenses are first tried. These HYBRID lenses; These are lenses in which the central part that does not contact the eye is hard, and the peripheral part that contacts the eye is soft. A good vision rehabilitation can be achieved with these HYBRID contact lenses. If the patient does not use contact lenses, Ring-Ring treatment can be applied. Intraocular toric lenses may be preferred in suitable patients.
2. Progressive disease:Stabilizing corneal progression - CCL (Corneal Cross Linking) treatment is applied to stop the progression. This treatment does not improve vision but only stops the progression of the disease.
