Correction of Aphakia using Scleral-Fixated Intraocular Lenses

Abstract

Inadequate support for installation of intraocular lenses (IOLs) in the capsular bag can occur as a consequence of complex cataract surgery, metabolic or hereditary disorders such Marfan's syndrome or pseudoexfoliation, or ocular trauma. When the capsular support is insufficient, patients may have surgical options such as iris or sclera fixation, alternate placement in the anterior chamber (ACIOLs), or both. Both of these methods' surgical techniques have come a long way in the recent few decades, leading to better eye and vision results. In the absence of iris or capsular support, the surgeon has two options: either affix the intraocular lens (IOL) to the sclera or leave the patient aphakic. Both sutures and tunneling the IOL haptics into the sclera without sutures are methods for fixing IOLs to the sclera. The following is a synopsis of the literature on scleral-fixated IOL implantation, including its specific risks, surgical approaches, outcomes, and pre-operative concerns.
