Objectives This study aimed to identify the etiology and the direction of dislocation of the natural crystalline lens or intraocular lens (IOL) in IOL intrascleral fixation surgery and to determine the change in intraocular pressure (IOP) after surgery. Methods We retrospectively investigated the diagnosis, direction of lens and IOL dislocation, and IOP before and after surgery (preoperatively and one day, one week, and one month postoperatively) in 236 eyes from 228 patients who underwent IOL intrascleral fixation at Chiba University Hospital between February 2015 and September 2020. Results IOL intrascleral fixation was performed in 48 (20.

Over the past two decades, both suture and sutureless techniques for scleral fixation of intraocular lenses have seen significant advancement, driven by improvements in methodologies and instrumentation. Despite numerous reports demonstrating the effectiveness, safety, and superiority of these techniques, each approach carries with it its own drawbacks, including an elevated risk of certain postoperative complications. This article delves into various surgical techniques for scleral fixation of posterior chamber intraocular lenses, discussing their procedural nuances, benefits, drawbacks, postoperative complications, and outcomes.

Intrascleral haptic fixation of intraocular lens (IOL) is an extremely useful technique to provide visual rehabilitation in eyes with inadequate capsular support. It requires exteriorization of haptics along with tucking of haptics in the scleral groove preferably and conventionally in the horizontal meridian. In eyes with large corneal diameter, there is difficulty in tucking enough length of the haptics into the intrascleral groove, carrying the risk of slippage of haptics and decentration of IOL.

Background: To evaluate intrascleral plug stability and correct centring of the IOL in three different surgical techniques using intraoperative anterior segment OCT.
Methods: This retrospective scientific study was conducted by reviewing patient records from the Ophthalmology Unit at the Civico Hospital of Palermo, covering the period between 2021 and 2022. Three distinct groups of patients, each consisting of 7 eyes from 7 individual patients, were included in this study.

Purpose Of Review: To describe recent evidence regarding surgical techniques for secondary scleral fixation of intraocular lenses (IOLs), with attention to information most relevant to the surgical practice of vitreoretinal surgeons.
Recent Findings: Recent studies have reported favorable outcomes in patients treated with scleral fixation of IOLs using Gore-Tex suture and flanged intrascleral haptic fixation (ISHF). ISHF can be achieved using trocar-cannulas or double needle-based techniques.
