Abstract
Objective: To determine the frequency of post cataract cystoid macular edema (CME) in three different types of cataract surgical procedures.
Methodology: This was a cross sectional study. Total 222 patients having
age related cataract were enrolled. Pre-operative optical coherence tomography (OCT) was performed to measure central macular thickness. Patients
were then randomly allocated to three groups on the basis of type of surgical
procedure; group A underwent phacoemulsification, group B, manual small
incision cataract surgery (MSICS) and group C, extra capsular cataract surgery
(ECCE). Post-operative OCT was done 06 weeks after surgery and the macular
thickness was compared to pre-operative values for diagnosis of CME. The
CME was then compared among the three groups.
Results: Male were 115 and female were 107. Mean age of the patients was
53.38 + 7.44 years, (41 to 70 years). A total of 27 (12.16%) patients had CME
following cataract surgery, 04 (5.12%) in group A , 06 (7.79%) in group B, 17
(25.37%) patients in group C had CME after surgery. Chi-square test was utilized for comparison of CME among the groups.
Conclusion: The frequency of CME following cataract surgery was low.
Phacoemulsification and MSICS gave almost similar, lower rates results while
ECCE was found to have higher rates of CME.
