Objective: To compare the frequency of CME, diagnosed on Optical Coherence Tomography, 6 weeks after cataract extraction, in patients after ECCE versus phacoemulsification. Materials and Methods: This study was carried out at Lahore General Hospital, Lahore in 6 months. It was a randomized controlled trial and sampling technique was non-probability purpose sampling. Patients fulfilling the inclusion criteria were included. A total of 200 cases were selected and were divided randomly by lottery method into 2 Groups. Group A included those who had to undergo ECCE and B included those who had to undergo phacoemulsification. The diagnosis of CME was established on Optical Coherence Tomography.The collected data was analysed statistically by using SPSS version 16. Both groups were compared for CME by using chi-square test. P-value <0.05 was considered as statistically significant. Results: In group A, minimum Central Point Thickness (CPT) was 120nm and maximum was 647nm with mean CPT of 215.68+-131.997nm, while in group B, minimum Central Point Thickness (CPT) was 121nm and maximum was 503nm with mean CPT of 172.31+-81.158nm. In group A, Cystoid Macular Edema (CME) was diagnosed in 23 (23%) cases, while in group B, Cystoid Macular Edema (CME) was diagnosed in 9 (9%) cases. Conclusion: Frequency of CME (diagnosed on OCT) at 6th post-operative week is more in post ECCE patients than in post phacoemulsification patients.
