Abstract: To investigate the changes in endothelial cell count [ECC] at 15 days and 2 month in eyes undergoing femtosecond laser assisted cataract surgery [FLACS]. METHODS:-Hundred [100] patients had one eye operated by femtosecond laser assisted cataract surgery [FLACS] [catalase precision laser system]. Endothelial count, hexagonality, central thickness was measured by using non-contact specular microscopy and pachymetry. preoperatively, 15 days and 2 months postoperatively. Results: Preoperatively endothelial cell count was 2500 or less in 35 eyes [35%],2501to 3000 in 52 eyes [52%] ,3001to 3500 in 10 eyes [10%],3501 to 4000 in 3 eyes [3%].15days post operatively endothelial cell count was 2000 or less in 5 eyes [5%],2001 to 2500 in 60 eyes [60%],2501 to 3000 in 34 eyes [34%], 3001 to 3500 in 1 eye [1%].2 month operatively endothelial cell count was 2000 or less in 5 eyes [5%], 2001 to 2500 in 61 eyes [61%],2501 to 3000 in 34 eyes [34%]. Conclusion: Femtosecond laser assisted cataract surgery [FLACS] appears to be as safe for corneal endothelial cells postoperatively.

1. INTRODUCTION An estimation of 670 million peoples, are visually impaired- 41 million people are blind and 268 million have low vision. Cataract are the most common ocular disease and leading cause of low vision and blindness all around world, accounts for 52% of the global burden of blindness, representing more than 20 million people in world. The cataract is responsible for blur vision. {11} Cataract can be defined as loss of transparency of the human crystalline lens in the eye. In which the refractive index of the lens significantly changes over distance and near approximating the wavelength of the light. The human crystalline lens consists of three structures: capsule, cortex and nucleus. In which the fetal nucleus is the most centrally located portion and new fiber is led down over time it turns into a hard-central nucleus {18}. The new fibers join each other form a Y-shaped suture line anteriorly and posteriorly. This central portion of the lens over time matures and hardens to form nuclear cataract which are treated with cataract surgeries. In most developing countries, blindness is associated with nutrition, economic and social implications. This is directly affecting on the populations, people who reside in underserved areas. An estimated 85-90% of people who are affected with cataract disease reside in developing countries. In current situation many infrastructure and technology are available to cure for the visually impaired persons. Moreover, So
