Abstract
Background: Macular oedema, including cystoid macular oedema, is one of the primary causes of unfavourable visual outcomes after cataract surgery.
Objectives: To determine the frequency of macular oedema after uncomplicated phacoemulsification.
Methodology: It was a descriptive case series study. The study was conducted at the Department of Ophthalmology, Services Hospital, Lahore. A total of 111 patients, aged 40-60 years, of both genders undergoing uncomplicated phacoemulsification, were selected. Operative time was noted. After surgery, patients were shifted to post-surgical wards and were discharged from there. All patients were followed up in the OPD for 12 weeks. After 12 weeks, patients were examined again for central macular thickness on OCT, and if the thickness rose by>30% from baseline, then macular oedema was labelled.
Results: The age range in this study was from 40 to 60 years, with a mean age of 51.53 ± 4.34 years. The majority of the patients, i.e. 66 (49.46%), were between 51 to 60 years of age. Out of these 111 patients, 51 (45.95%) were male and 60 (54.05%) were female, with a male-to-female ratio of 1:1.2. Mean pre-therapy CMT was 211.40 ± 10.98 µm, and post-therapy was 237.48 ± 9.79 µm. Frequency of macular oedema after uncomplicated phacoemulsification was seen in 20 (18.02%) patients.
Conclusion: This study concluded that the frequency of macular oedema after uncomplicated phacoemulsification is quite high.
