Outcomes of 23- and 25-gauge transconjunctival sutureless vitrectomies for dislocated intraocular lenses

摘要

Abstract Purpose To compare the outcome of 23-gauge as compared with 25-gauge transconjunctival sutureless vitrectomy (TSV) in the management of dislocated intraocular lenses (IOLs). Design Retrospective, non-consecutive, comparative, interventional case series. Participants Patients with dislocated intraocular lens who underwent sutureless PPV using either 23-gauge or 25-gauge instruments. Methods The patients who presented with a dislocated IOL, underwent TSV with repositioning of the intraocular lens, either in the sulcus or scleral-fixated sutured/glued. Results Of the total 61 eyes, 33 (54.09%) underwent 23-gauge TSV and 28 (45.90%) underwent 25-gauge TSV. The mean logMAR BCVA at baseline and 6 months after surgery was 0.8 and 0.46 in the 23-gauge group, and 0.82 and 0.47 in the 25-gauge group. There was no significant difference in logMAR BCVA values between the two groups at any time point of time during the follow-up. The mean postoperative IOP on postoperative day 1 was 14.76 ± 5.4 in 23-gauge group and 17.57 ± 7.9 in the 25-gauge group (p = 0.10). Retinal break was noticed intraoperatively in two cases in 23-gauge group and in three cases in 25-gauge group (p = 0.509). Postoperative complications included IOL decentration in one case of 23-gauge vitrectomy and two cases in 25-gauge group (p = 0.5), cystoid macular edema in four patients in 23-gauge group and six cases of 25-gauge group (p = 0.3) and retinal detachment in one case in each group (p = 0.9). Conclusions 25-gauge appears to be as safe and as effective as 23-gauge TSV in the management of dislocated intraocular lenses.
