Cystoid Macular Edema After Uncomplicated Phacoemulsification

To highlight the occurrence of cystoid macular edema (CME) after uneventful phacoemulsification and to emphasize the role of early detection using optical coherence tomography (OCT) for optimal visual recovery.

A tertiary ophthalmology center, Department of Cataract and Refractive Surgery, where patients undergo standard phacoemulsification with posterior chamber intraocular lens implantation.

A 67-year-old female with senile cataract in the right eye underwent uncomplicated phacoemulsification. Medical history included well-controlled type 2 diabetes. Preoperative BCVA was 20/50. Surgery was uneventful.

Two weeks postoperatively, the patient reported blurred vision and mild photophobia. BCVA decreased to 20/80. Anterior segment examination was unremarkable; the posterior segment showed mild macular thickening. OCT confirmed CME with central retinal thickness of 380 µm. No diabetic retinopathy was detected.

The patient was treated with a combination of topical NSAIDs and corticosteroids. Follow-up at 4 and 8 weeks showed progressive reduction in macular thickness to 270 µm and BCVA improved to 20/40. Complete resolution was achieved by week 12 with full symptom recovery.

Conclusion

CME can occur even after uncomplicated phacoemulsification, particularly in patients with systemic risk factors such as diabetes. Early detection with OCT allows prompt treatment and favorable visual outcomes.

Take-Home Message : Routine postoperative OCT monitoring is essential to detect CME early, enabling timely intervention and maximizing visual recovery after cataract surgery.
