Optical coherence tomography of macular thickness after cataract surgery

PURPOSE: To evaluate macular thickness changes after uneventful cataract surgery using optical coherence tomography (OCT) and compare the findings with those of flare and cell measurements of the anterior chamber. SETTING: Clinique Sourdille, Nantes, France. METHODS: In this retrospective study, 41 eyes having uneventful cataract surgery with a clear corneal small incision and intracapsular fixation of a foldable intraocular lens were evaluated by OCT and laser flare and cell measurements preoperatively and 1, 8 to 12, and 30 to 60 days postoperatively. RESULTS: Some postoperative increase in macular thickness was noted in 11 eyes. This was not related to a higher postoperative flare. Visual consequences were proportional to the macular elevation. CONCLUSION: Clinical and subclinical thickness changes, without breakdown of the blood-aqueous barrier, can be detected after cataract surgery. Most of these changes resolve spontaneously, but their mid- and long-term significance is unknown.
