Intrascleral intraocular lens implantation in transconjunctival era: An updated review of technique and complications

Abstract

This systemic review focuses on the most recent trend in intrascleral intraocular lens (IOL) implantation in transconjunctival era, while also exploring the surgical issues associated with this method in diverse circumstances. Essentially, complicated cataract surgery, trauma, and/or genetic disorders may be accompanied by impairment of zonular and/or capsular support, for which several secondary IOL implantation options exist, including anterior chamber, iris-fixated, and scleral-fixated IOLs. Since the 1980s, when intrascleral IOL fixation made its debut, surgical techniques for implanting scleral-fixated IOLs have undergone multiple changes. Indeed, the efficacy of different surgical methods varies considerably and is greatly determined by the patient’s prior ocular conditions as well as the surgeon’s skill. Despite advances in surgical methods, studies are constrained by their retrospective nature, small sample sizes, and, most importantly, brief follow-up periods. Furthermore, the range of different procedures available, aside from transconjuctival intrasclear IOL fixation methods, suggests that the optimal approach to secondary IOL implantation in the absence of zonular or capsular support has yet to be determined. © © 2024 The author(s)
