Intraocular Lens Fixation Technique Without Corneal Incision in Minimally Invasive Vitrectomized Eyes

Introduction To introduce a modified technique for primary/secondary intraocular lens (IOL) fixation without corneal incision in vitrectomized eyes. Methods Consecutive case series who had undergone previous or concomitant pars plana vitrectomy (PPV) to have primary/secondary IOL fixation were prospectively included. A self-sealing scleral incision was made underneath the superior scleral flap, through which the IOL was inserted into the anterior chamber. The suture tied with the IOL passed through the sclera to fix the IOL in the ciliary sulcus. Patients were followed up for at least 3 months. Main outcomes were best corrected visual acuity (BCVA), intraocular pressure (IOP), surgically induced astigmatism (SIA), and intraoperative and postoperative complications. Results A total of 31 patients were included in the study. The mean follow-up time was 5.35 +/- 4.14 months. The BCVA (log MAR unit) improved from 0.97 +/- 0.58 preoperative to 0.42 +/- 0.36 postoperative (P < 0.001). Mean IOP remained unchanged (preoperative IOP 14.03 +/- 2.90 mmHg, postoperative IOP 13.26 +/- 3.46 mmHg, P = 0.130). The mean SIA was 0.91 +/- 0.76 diopters. No obvious intraoperative and postoperative complications were observed. Conclusion This method has favorable postoperative visual recovery and IOP control. This modified method could be taken into account as an option by surgeons in vitreoretinal surgery.
