A study on the safety and efficacy of posterior chamber phakic intraocular lens (refractive implantable lens) in high myopia

Abstract

Background: Myopia is the most common refractive error worldwide causing visual impairment in children and adults. The prevalence of high myopia varies with age and ethnicity. High myopia has been found to be visually debilitating and affects day-to-day activities of the individual. Aim: This study aimed to analyze the efficacy and visual outcomes of posterior chamber phakic intraocular lens-refractive implantable lens (RIL) in high-myopia patients. Methods: This prospective study was conducted in a tertiary care center during February 2017–February 2018. Results: This study included 50 eyes of 34 patients, which showed 82% of eyes had uncorrected visual acuity equal or better than preoperative best-corrected visual acuity and 52% eyes had visual acuity of 6/6. No incidence of cataract was observed in this study. Conclusion: Refractive results after RIL implantation are found to be safe and satisfactory and has favorable visual outcome.
