Abstract:
Purpose:We investigated the changes in ocular higher-order aberrations (HOAs) between sutured scleral fixation and modified Yamane sutureless scleral fixation.
Methods:We retrospectively reviewed 20 patients (20 eyes) who underwent sutured scleral fixation and 22 patients (22 eyes) who underwent modified Yamane sutureless scleral fixation. The best corrected visual acuity (BCVA) and HOAs were measured preoperatively, and at 3 months postoperatively, and the two groups were compared.
Results:BCVA was significantly improved in both sutured scleral fixation and modified Yamane sutureless scleral fixation (p = 0.038, 0.015, respectively). The internal optic HOAs decreased significantly after scleral fixation both in both groups (p = 0.012, 0.033, respectively). Postoperative internal optic HOAs were significantly higher in modified Yamane sutureless scleral fixation group than in sutured scleral fixation group. (p = 0.034) Postoperative third-order aberrations, coma-like aberrations were significantly higher in modified Yamane sutureless scleral fixation group than in sutured scleral fixation group. (p = 0.032, 0.038, respectively)
Conclusions:Sutured scleral fixation showed more effectively decreased internal optics HOAs. IOL tilt and decentrations correlated with internal HOAs and thus should be avoided particularly in modified Yamane sutureless scleral fixation.
