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

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 ( P < 0.05). The mean preoperative IOP was 21.9 ± 12.6 mmHg, and the mean postoperative IOP was 16.9 ± 4.5 mmHg at 3 months ( P  = 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 ( P  = 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 ( P < 0.005). 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.
