To review the safety of the implantable phakic contact lens (IPCL V1, Caregroup Sight Solutions, India) for correction of myopia and myopic astigmatism.Retrospective interventional case series including 134 eyes which underwent IPCL implantation for correction of myopia and myopic astigmatism at a tertiary eye care hospital in South India. Intraoperative and postoperative complications were analyzed. The following parameters were analyzed at preoperative and 1, 6 and 12 month postoperative visits: visual acuity (in logMAR) and manifest refraction, slit lamp bio microscopy, dilated fundus examination, IOP and endothelial cell density measurement.No intraoperative complications were noted. Cataract was the most common postoperative complication, wherein three eyes (2.2%) underwent observation for visually insignificant anterior subcapsular cataract and one eye (0.7%) required surgical intervention. Four eyes developed transient increased IOP due to steroid response (3 eyes) and pupillary block glaucoma (1 eye). The endothelial cell loss noted over a 1-year follow-up was 2.01%±4.12% (P=0.71). One eye developed hypopyon on the third postoperative day, which resolved subsequently with an unaided vision of 20/20. No vision threatening complications were noted. The mean follow-up in the cohort was 25.66±16.45 months.The IPCL is a safe and effective treatment modality for correction of myopia and myopic astigmatism.
