Outcome of pre-existing corneal astigmatism by incision at steep axis in a tertiary care hospital

Purpose: to measure post-surgical astigmatic correction through phacoemulsification at steep axis. type of study: quasi-experimental sampling technique: non-randomized consecutive sampling materials and methods: this quasi-experimental study was performed on 460 eyes of 350 patients of cataract reporting at eye department,combined military hospital (cmh),lahore from oct 2010 to dec 2011 who had pre-existing corneal astigmatism. they were managed by phacoemulsification with corneal incision at steep axis to extract cataract and correct astigmatism. results: induced refractive change caused by corneal incision at steep axis showed an overall improvement in pre-operative astigmatism with minimum level of significance conclusion: corneal incision at steep axis is an effective technique to reduce pre-operative astigmatism.
