Changes in higher-order aberrations after vitrectomy for vitreomacular interface diseases.

Abstract

To evaluate ocular wavefront aberrations after vitrectomy in patients with vitreomacular interface diseases. Thirty eyes of 30 patients with vitreomacular interface diseases were included in this prospective study. A Sirius topographer (SCHWIND eye-tech-solutions, Germany) was used to measure corneal aberrations and a Hartmann Shack aberrometer (IRX-3; Imagine Eyes, Orsay, France) to measure ocular aberrations. Data were recorded at baseline and 3months after vitrectomy. Eight patients were excluded due to the formation of cataract during the post-operation follow-up period. Data of 22 eyes (13 eyes with epiretinal membrane, two eyes with epiretinal membrane with vitreomacular traction, one eye with vitreomacular traction, and six eyes with macular hole) were analyzed for the study. The corneal aberrations such as coma, trefoil, spherical aberration, and root mean square of total higher-order aberrations did not significantly change after vitrectomy. The preoperative ocular aberrations such as coma 0.33 (0.14-0.47) µm, trefoil 0.28 (0.15-0.44) µm, root mean square of higher-order aberrations 0.51 (0.45-0.68) µm, root mean square of total aberrations 1.38 (1.16-2.60) µm were significantly reduced to 0.21 (0.14-0.29) µm, 0.20 (0.14-0.30) µm, 0.36 (0.21-0.52) µm, 0.15 (1.13-1.41) µm, respectively, after vitrectomy. The ocular higher-order aberrations were significantly reduced after vitreomacular surgery for vitreomacular interface diseases.
