Radial Keratotomy in Keratoconus Cases

Keywords

radial keratotomy; keratoconus; optical rehabilitation

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.
