Brief summary

The primary purpose of the study is comparision of surgically induced astigmatism of conventional coaxial phacoemulsification and microincision coaxial phacoemulsification. Hypothesis of study is that surgically induced astigmatism is less using microincision cataract surgery in comparision with conventional coaxial phacoemulsification

Interventions

Microincision coaxial phacoemulsification: cataract surgery using phacoemulsification through 2.2 millimeters incision performed by Alcon Legacy machine.This procedure is done intra operatively
