ABSTRACT
INTRODUCTION: In cases of inadequate capsular support for intraocular lens (IOL) implantation, iris-claw IOL is a practical option. Iris-claw IOL can be implanted anteriorly or retropupillary. In this study, we compare the outcome of implantation of iris-claw IOL between anterior and retropupillary locations. METHODS: We retrospectively examined the characteristics and outcomes of patients who underwent iris-claw "Artisan®" intraocular lens implantation (IOL) during the period of January 2014 to July 2020. The study population included all patients who underwent iris-claw IOL implantation, whether as a primary or secondary implantation, regardless of the causative indication. The study population was categorized by location of implantation and indication. The outcome was compared by visual acuity and postoperative complications. RESULTS: In this study, 171 eyes of 151 patients were included. Iris-claw IOL was implanted anteriorly in 110 (64.3%) eyes. The most common indication for iris-claw IOL was complicated cataract surgery, followed by ectopia lentis and by trauma. Patients with retropupillary position achieved better visual outcome whatever the causative indication. Anterior iris-claw IOL patients had more high intraocular pressure readings and macular edema. CONCLUSIONS: This study revealed that retropupillary iris-claw IOL may achieve better visual outcome without significant postoperative complications. Further prospective studies and trials on larger sample sizes are needed.
