Aphakic macular oedema: a two-year follow-up study.

A 2-year follow-up study was carried out on patients known to have developed aphakic macular oedema 6 weeks postoperatively, and the results were compared with those in a control group who had not developed oedema. Four eyes (12%) still had macular oedema, the visual acuities ranging between 6/5 and 6/9. There was no significant difference in visual acuities at 2 years between the 2 groups of patients. Visual acuity had significantly improved between 6 weeks and 2 years in the eyes that had macular oedema at 6 weeks after extraction. Factors causing persistence of aphakic macular oedema are discussed.
