Study Overview
Brief Summary
SURGICALLY INDUCED ASTIGMATISM (SIA) IN TEMPORAL AND ON-AXIS CLEAR CORNEAL INCISION IN PATIENTS UNDERGOING PHACOEMULSIFICATION – RANDOMIZED CONTROLLED TRIAL
Primary objectives: To compare the Surgically Induced Astigmatism (SIA) between Temporal Clear Corneal Incision (TCCI) and On-Axis Clear Corneal Incision (OCCI) in patients undergoing phacoemulsification
Secondary objectives:
1. To compare the coupling ratio between temporal clear corneal (TCCI) and On-Axis Clear Corneal Incision (OCCI) in patients undergoing phacoemulsification
2. To compare the Visual outcome between temporal clear corneal (TCCI) and On-Axis Clear Corneal Incision (OCCI) in patients undergoing phacoemulsification
Description of study groups (for comparative/analytical studies only):
In this study, the participants will be divided into 2 groups
GROUP A – patients undergoing phacoemulsification with Temporal Clear Corneal Incision
GROUP B - On axis Clear corneal incision. Pre and post op keratometry values, astigmatism, coupling ratio, visual acuity will be compared between the two groups.
