Study Overview
Brief Summary
Intracorneal rings are indicated in patients whose central cornea does not present opacity and whose visual acuity is not satisfied despite correction with lenses or linked to an intolerance to lenses.
Surgeries such as crosslinking and intracorneal rings placement are alternatives to corneal transplantation with the expected effects: stabilization of the disease for corneal collagen crosslinking and visual rehabilitation by the placement of intracorneal rings.
The main objective of this study is to evaluate visual benefit1 year after placement of intracorneal rings using laser in keratoconus
