To evaluate the safety and clinical outcome of toric Implantable collamer lenses (ICL) in patients of stable keratoconus.

Prospective, non randomized, non comparative, interventional study of ICL implantation in 17 eyes of 11 patients with keratoconus was carried out from January 2012 to December 2013 .Progressive keratoconus was first stabilized with collagen cross linkage. Minimum interval of 3months and maximum to one year was kept between the stabilization procedure and ICL implantation. Data was collected pre op, at 3 months post CXL and at 6 month follow up visit after ICL implantation. Toric ICL was placed and alignment was done by using Ray tracing technology.

Patients were in the age group of 19 – 42 years with majority (41.46%) in the age group of 24 – 28 years. Preop refractive error varied from spherical equivalent of -1.62D to -25D, with mean spherical equivalent of – 9.75D. Post surgery V/A showed 1 line improvement in 8 eyes, 2 line improvement in 5 eyes, 3 line and 4 line improvement in 2 eyes each. V/A was status quo in 14 eyes and 2 (2.99%) eyes showed deterioration of V/A. 1 eye had secondary glaucoma.

Implantation of ICL following stabilization of keratoconus with C3R is a safe and effective option. Hence ICL is a much awaited definitive and rewarding form of treatment in patients with keratoconus.
