Abstract
Introduction: Posterior polar cataract is a rare form of congenital cataract with incidence ranging from 3 to 5 in 10001-2. It is bilateral in 65–80% of the cases with no gender predilection3. Posterior polar cataract presents a special challenge to the surgeon because of its predisposition to posterior capsular dehiscence and possible nucleus drop during surgery. The present study aims to evaluate the surgical outcome of phacoemulsification and manual small incision cataract surgery in patients with posterior polar cataract. Material and Methods: This prospective study included 119 eyes of 118 patients with posterior polar cataract, who underwent surgery at Sagarmatha Choudhary Eye Hospital, Lahan, Nepal, between March 2013 to March 2014. All patients underwent complete ophthalmologic examination including vision, slit-lamp Biomicroscopy, IOP measurement and posterior segment examination. Patients with complicated cataract, glaucoma, corneal opacity/ degeneration, retinal pathology were excluded from the study. Patients were scheduled for cataract surgery either with phacoemulsification or manual SICS with fish hook technique. Informed consent was obtained after explaining the type of surgery and possibility of posterior capsular rupture, a relatively long operative time, secondary posterior segment intervention, and a delayed visual recovery. Results: 119 eyes of 118 patients were included in the study. There were 63 males (53.39%) and 55 females (46.61%). The mean age was 53.24 (range 17-80) years. Among 118 patients 24 patients had other eye operated previously, 2 patients had lost their one eye due to trauma and in remaining 92 patients, 71 patients had bilateral posterior polar cataract (77.17%). Phacoemulsification was performed in 48 eyes and SICS in 71 eyes. The most common intraoperative complication was posterior capsule rupture, seen in 22 eyes (18.49%). Of these, 7 eyes(14.58%) had undergone phacoemulsification, 15(21.13%) had manual SICS. 103
