Sutureless Intrascleral Posterior Chamber Intraocular Lens Fixation: Analysis of Clinical Outcomes and Postoperative Complications

摘要

Purpose . To report a technique for performing sutureless intrascleral fixation of a posterior chamber intraocular lens (PC-IOL) and analyzing the clinical outcomes and postoperative complications. Study Design . 68 eyes of 66 patients who received the technique were studied retrospectively. Methods . The best-corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), IOL tilt and decentration, corneal topography ( K 1 and K 2), and postoperative complications were determined at 3 months. Results . The mean preoperative BCVA was 1.63?±?1.24 logMAR units, and the mean postoperative BCVA was 0.74?±?0.59 logMAR units at 3 months ( ). The mean preoperative IOP was 21.9?±?12.6?mmHg, and the mean postoperative IOP was 16.9?±?4.5?mmHg at 3 months ( ?=?0.001). The mean preoperative corneal topography (K1 and K2) was K 1?=?42.14?±?1.91 and K 2?=?43.54?±?1.51; the mean postoperative corneal topography ( K 1 and K 2) was K 1?=?43.03?±?2.18 and K 2?=?43.40?±?1.71 at 3 months ( ?=?0.678 and 0.468, respectively). The mean preoperative spherical equivalent was +11.00?±?13.19 diopters ( D ), and the mean postoperative spherical equivalent was +0.06?±?0.86 D ( ). The mean IOL tilt was 2.4?±?1.7°, and the mean decentration was 0.35?±?0.21?mm. The mean ACD was 4.31?±?0.29?mm. Conclusions . The 27-gauge sutureless intrascleral PC-IOL implantation technique minimizes intraoperative injury, simplifies procedure, and provides good PC-IOL fixation with few postoperative complications.
