Comparison of complications of intrascleral fixation according to the extent of vitrectomy

BMC Ophthalmol. 2024 Apr 9;24(1):154. doi: 10.1186/s12886-024-03430-9.

Abstract

Background: Intraocular lens (IOL) fixation is performed after intraoperative anterior or total vitrectomy. This study aimed to compare the intraoperative and postoperative complications of these two techniques.

Methods: This retrospective study included 235 eyes that underwent intrascleral fixation surgery at our hospital between July 2014 and January 2021. The eyes were classified into the anterior vitrectomy group (A-vit group; 134 eyes) and the pars plana vitrectomy group (PPV group; 101 eyes). The age, preoperative and postoperative best-corrected visual acuity, observation period, preoperative and postoperative intraocular pressure, and the incidence of intraoperative and postoperative complications were assessed.

Results: Intrascleral fixation was performed more frequently in the PPV group, and a significant difference was observed between the eyes with a history of vitrectomy and eyes with scleral buckles (p = 0.00041). In terms of the incidence of postoperative complications following intrascleral fixation, the incidence of low intraocular pressure postoperative was higher in the PPV group than that in the A-vit group, and a significant difference was observed between the two groups (p = 0.01).

Conclusions: The visual outcome and complications following intrascleral fixation did not differ according to the extent of vitreous excision.
