Keratoconus Treatment in Patansaongi
Keratoconus (KC) is the condition in which the cornea becomes thin and slowly bulges outwards to form a cone shape. This cone shaped cornea also has an irregular surface which leads to blurred vision. It usually affects both the eyes.
Its typical presentation in in early 20 years of age. It runs in family. Due to change in the shape of cornea, patients present with frequent change in glasses. Usually they have irregular astigmatism. Even the best corrected visual acuity is not 100 % in most of the cases. In later stages, cornea may get swollen up or scarred leading loss of vision.
- Exact pathogenesis of KCN is unknown.
- Risk factors include a history of eye allergies, rigid contact lens wear and vigorous rubbing of the eyes.
- KCN is seen in connective tissue disorders, Down’s syndrome, Mitral Valve prolapse (a disease of the heart valves) and Atopic Dermatitis (a skin disease).
1. Blurred vision (distortions, glares, haloes, ghost images, diplopia {double vision})
2. Intolerance to bright light
3. Headache after eyestrain
4. Pain in late stage
Once it is observed that KCN is progressive with the help of sequential topography reports, to stop progression of KCN, C3R is done. Full form of C3R is Corneal Collagen Cross linking with Riboflavin. It strengthen the bonds between collagen in cornea. This procedure stops progression of KCN in most of the cases.
For visual rehabilitation after C3R , patient can be advised
- Glasses: It can correct blurred vision in the initial stages.
- Rigid Gas Permeable Contact Lenses: These are hard contact lenses which are specially designed for KCN.
- Scleral Contact lenses: It forms vault over cornea and its periphery is in touch with sclera. Piggybank CL & hybrid CL can be used to improve vision.
Don’t rub your eyes. If itching is intolerable, visit your ophthalmologist.
If there is frequent change in your glass number or there is blurred vision even after wearing glasses, please visit your ophthalmologist.
