Summary

To compare visual and refractive measurements of intrastromal corneal ring segments versus toric phakic posterior intra-ocular lenses implantation in keratoconus

Detailed description

* The study is a prospective comparative interventional case series. It will be conducted in Minia university hospital and Roaa Laser Vision Correction Center. * Fourty eyes will be evenly allocated into two groups: Group (A): 20 eyes will undergo corneal collagen cross linking (epithelium off) 1 month after Femtosecond laser assisted intrastromal corneal keraring segments. Group (B): 20 eyes will undergo toric phakic posterior IOL implantation 1 year after corneal collagen cross linking (epithelium off). • An informed written consent to be involved in the study will be obtained from each patient.

Conditions
