영문 초록

Purpose: To investigate the long-term results of transscleral fixation of posterior chamber intraocular lens (IOL) for unstable posterior capsular supporting structure. Methods: We performed a retrospective review of 67 patients (67 eyes) with unstable posterior capsular supporting structure who underwent transscleral fixation at Soonchunhyang University Bucheon Hospital from March 2005 to January 2013. Transscleral fixation without scleral flap was performed by a single surgeon. We analyzed the causes of transscleral fixation and compared postoperative best-corrected visual acuity (BCVA) and spherical diopter. Results: Among the 67 eyes of 67 patients, the causes of transscleral fixation included IOL subluxation (33 cases, 49.2%), IOL dislocation (11 cases, 16.4%), intraoperative posterior capsule rupture (8 cases, 11.9%), aphakia associated with previous intraocular surgery (7 cases, 10.4%), crystalline lens disorder with zonular dialysis (4 cases, 5.9%) and IOL opacity (4 cases, 5.9%). The mean BCVA before surgery was 1.26 ± 0.94 (log MAR) and the visual acuity improved to 0.59 ± 0.71, 0.60 ± 0.69, 0.58 ± 0.70, 0.55 ± 0.70, 0.60 ± 0.58 and 0.66 ± 0.70 (1 week, 1 month, 3 months, 1 year, 3 years and 5 years, respectively, after the surgery; p < 0.05). Conclusions: Posterior chamber IOL transscleral fixation in unstable posterior capsular supporting structure is effective for increasing visual acuity and spherical diopter. Specifically, the most improvement was observed at one month after surgery. Transscleral fixation is an adequate surgical procedure for fast improvement of visual acuity with long-term effects.
