Abstract
Background: Myopia or near sightedness is a very common refractive error seen among children and adults. It is an eye disorder where the light focuses in front of the retina, causing distant objects to be blurred while the near objects appear normal. High myopia can be visually debilitating and affect one’s day to day activities.
Aim: To analyse the efficacy and visual outcome of using posterior chamber phakic intraocular lens- refractive implantable lens (RIL) for high myopic patients.
Methods: A prospective study was conducted in a tertiary care centre. The study included 50 eyes of 34 patients. The preoperative best corrected visual acuity was compared with their post operative uncorrected visual acuity along with the IOP changes, endothelial cell loss and associated complications. The whole database was recorded and statistically analysed.
Results: Out of the 50 eyes that were taken for the study,94% of the eyes had uncorrected visual acuity equal to better than preoperative best corrected visual acuity and 34 %of the eyes had a visual acuity of 6/6. The intraocular pressure was less than 20 mmHg postoperatively in all patients. No incidence of cataract was observed in this study.
Conclusion: It is found that the visual outcome was favourable and satisfactory after RIL implantation.
