Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* 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.
