To examine the internal optical aberration in pseudophakic eyes with silicone oil tamponade and to investigate the changes of aberration after silicone oil removal
Seven eyes in 7 patients, who had received phacovitrectomy and silicone oil tamponde, were included in this study. Internal aberration was measured with KR-1W wavefront analyser(Topcon, Tokyo, Japan). Aberrometry was repeated 1 month after silicone oil removal operation, and was compared with preoperative internal aberration.
After silicone oil removal, myopic shift of -4.23 D was observed in ocular total aberration. Ocular total high order aberration (HOA) was significantly high preoperatively (0.211-1.739 at 4mm), but decreased postoperatively (0.049-0.505). Primary cause of HOA in silicone oil filled eye was Coma-like aberration (0.112-1.624 preoperatively, 0.031-0.178 postoperatively).
Silicone oil tamponade induces hyperopic spherical aberration and coma-like aberration, which were decreased significantly postoperatively. Silicone oil-induced ocular coma can cause decrease of best-corrected visual acuity and quality of vision.
