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. To exteriorize a larger segment of haptic for tucking, we describe a novel technique that involves creation of scleral groove at the posterior limbus and exteriorization of haptic through a small peripheral iridectomy through the posterior limbus. This provides a larger segment of haptic to tuck into the groove that might prevent slippage and decentration of IOL in eyes with megalocornea.

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.

Our systematic review and meta-analysis elucidates the postoperative complication rates associated with 3 major surgical approaches, including the scleral tunnel, glued, and flanged techniques, for sutureless intrascleral intraocular lens (IOL) fixation. An online search was performed for articles published in PubMed and EMBASE between January 1, 1975, and January 7, 2023. Original studies reporting postoperative complications of sutureless intrascleral IOL fixation were included.

Methods: This prospective, longitudinal, single-site, single-surgeon study's setting was the Department for Ophthalmology and Optometry, Medical University of Vienna, Austria. Patients who received IOL implantation via the four-flanged technique were followed up to 3 months after the operation.

Background: This study aimed to report and recall a simple method to remove the lens capsule ab externo when performing intrascleral fixation of an intracapsular intraocular lens (IOL) dislocation with reuse of the IOL.
Case Presentation: A 43-year-old Japanese male patient underwent pars plana vitrectomy, phacoemulsification, and IOL fixation for rhegmatogenous retinal detachment in the right eye 10 years prior. A 3-piece IOL was intraocularly fixed during the initial procedure.
