Abstract

Aim: To evaluate post operative visual outcome and complications of retro-pupillary iris fixated Intracoular lens (IOL) in aphakia.
Materials and Methods: This is a prospective interventional case study conducted at our tertiary eye care centre from March 2018 to February 2019 All monocular aphakias secondary to any cause with no capsular support, good iris diaphragm support and BCVA of better than 6/60 were included. Patients who required combined procedures like trabeculectomy and retinal procedure were excluded. Patients with poor endothelial count/ corneal decompensation, any posterior segment pathologies, pre existing glaucoma and any form of uveitis were also excluded from the study. Pre operative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome was to assess the post operative visual acuity and secondary outcome was to analyse post operative complications at various intervals up to 6 months after surgery.
Results: Our study comprised of thirty eyes of 30 aphakic patients. RPIFIOL was inserted as primary intraocular lens in 18 patients (%) and secondary intraocular lens in 12 patients(%). Baseline best corrected visual acuity was 0.831±0.66 logMAR. Four patients had light perception at baseline. The mean best corrected visual acuity was 0.77±0.35 logMAR at month 1, 0.64±0.36logmAR at month 3 and 0.53±0.33logmAR at month 6 respectively. Mean intraocular pressure at baseline was 16mmHg. Mean intraocular pressure at month 1, 3 and 6 were 17mmHg, 16mmHg, and 16mmHg. Among the complications, twelve eyes (40%) had significant ovalisation of pupil at post operative month 1 which persisted at month 6, two eyes(6.66%) had transient ocular hypertension (OHT), and none of the eyes progressed to glaucoma. Choroidal detachment was noted in 2 eyes (6.66%), CME in 3 eyes (9.99%), 1 eye (3.33%) had retinal detachment and 2 eyes (6.66%) had one haptic disenclavation. Among the complications, ovalisation of pupil was the most common observed one.
Conclusion: Retro-pupillary Iris fixated IOL is an effective, safe and simple procedure for management of aphakia in eyes with no posterior capsular support.
