AIM: To study the outcome of Collagen Cross Linking therapy in keratoconus patients, in a Tertiary eye care centre in North East India
OBJECTIVE:
PRIMARY OBJECTIVE : To access the functional and morphological outcome in terms of visual acuity, refraction, topographic changes after corneal collagen cross-linking in progressive advanced keratoconus patients.
SECONDARY OBJECTIVE: To accesses the changes of endothelial cell count and contrast sensitivity before and after the procedure.
DESIGN: Hospital based prospective, interventional, case controlled study nonrandomized.
PARTICIPANTS: Sixty eyes of thirty patients undergoing C3R procedure between April 2015 and March 2016 that is for a period of 1 year.
