Introduction: Keratoconus is a developmental anomaly of cornea. Non inflammatory thinning and cone shaped protrusion of cornea causes significant visual disturbance and discomfort. Objectives: This study was done with prime objective of choosing appropriate contact lens from available two options (RGP lens and Rose K lens) for various grades of keratoconus. Materials and Methods: In present study 21 eyes of 14 patients were selected; who presented in our hospital with various grades of keratoconus. Time period of study is twelve months. Result: In present study 3 eyes of mild keratoconus, 11 eyes of moderate keratoconus, 6 eyes of advanced keratoconus and 1 of severe keratoconus were included. Conclusion: Overall visual acuity and comfort is more with Rose K lens in comparison with RGP lens especially in advanced and severe cases
