Radial Keratotomy in Keratoconus Cases
Efficacy of Radial Keratotomy in the Optical Rehabilitation of Mild to Moderate Keratoconus Cases
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.
