Previous studies have demonstrated that macular thickening occurs shortly after cataract surgery by phacoemulcification. We investigated the change in macular thickness over time following uncomplicated phacoemulsification.
30 nonconsecutive patients with best-corrected visual acuity of 20/30 or better after uneventful phacoemulcification were included. Excluded were patients with diabetes, myopia, macular pathology, glaucoma and uveitis. Macular thickness in the operated eye and non-operated fellow eye was measured with the optical coherence tomography (OCT) 1 and 6 months postoperatively.
The mean (+/- SE) foveal thickness in the operated eyes at 1 month postoperatively was 203.5+/-11 micron and decreased to 187.1+/- 9 micron at 6 month (p< 0.023). The mean (+/- SE) macular volume of the operated eyes at 1 month was 7.1+/-0.15 mm3 and it decreased to 6.9+/-0.13 mm3 at 6 month ( p< 0.002). There were no similar changes in the non-operated eyes.
OCT measurements demonstrated that the subclinical macular thickening present at 1 months after phacoemulsification decreased spontaneously at 6 months following surgery.
