Sutured scleral fixation of existing subluxated/dislocated acrylic one-piece intraocular lenses

To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses (IOLs). This study retrospectively enrolled a consecutive series of patients who underwent a surgery of sutured existing subluxated or dislocated IOLs from October 2018 to June 2020. All patients underwent comprehensive preoperative and postoperative ophthalmologic examination, and data were collected including age, sex, surgical indications, best-corrected visual acuity, refractive error, intraocular pressure. Presence of intraoperative and postoperative surgical complications was documented. A total of 20 consecutive cases were enrolled for analysis with mean final follow-up period 9.8±5.3mo. Visual acuity improved from a mean of 0.35 (0.46±0.32 logMAR) preoperatively to 0.61 (0.21±0.18 logMAR) at the 3-month follow-up ( =0.002). The mean amount of preoperative keratometric astigmatism and total postoperative refractive astigmatism was -1.24±0.80 diopters (D) and -1.42±0.97 D, respectively. There was no statistically significant difference between preoperative and postoperative astigmatism ( =0.156). The mean IOL-induced astigmatism was -0.23±0.53 D. The mean spherical equivalent at the 3-month follow-up was -0.1±0.94 D. No major complications were noted during the follow-up period. Surgical techniques using sutured scleral fixation of existing subluxated or dislocated acrylic one-piece IOLs result in favorable visual and refractive outcomes without major complications.
