Efficacy of Radial Keratotomy in the Optical Rehabilitation of Mild to Moderate Keratoconus Cases
Completed
- Conditions
- Radial Keratotomy in Keratoconus Cases
- Interventions
- Procedure: radial keratotomy
- Registration Number
- NCT01879631
- Lead Sponsor
- Nisa Hastanesi
- Brief Summary
Keratoconus is a progressive ectatic disorder that steepens the cornea resulting in a conical shape. Radial Keratotomy can provide an optical rehabilitation by its flattening effect. It can also halt the progression of disease owing to fibrotic activation in perpendicular corneal incisions.
