Journal Title: Journal of Krishna Institute of Medical Sciences University - Year 2014, Vol 3, Issue 2
Abstract
Background:With accurate estimation of power of intraocular lens (IOL), uncomplicated cataract surgery and uneventful post operative period, the implant is capable of providing a visual acuity of 6/6 and a normal field of vision. However, post operative results are not always according to the expectations. This study is an attempt to find out causes of subnormal vision post uneventful cataract surgery with posterior chamber intraocular lens by various surgical techniques in Krishna Institute of Medical Sciences, Karad, Maharashtra, India. [i]Aims and Objectives: [/i]Study the incidence of subnormal vision in patients who have undergone uneventful cataract surgery with posterior chamber IOL implant and relation between the type of surgery and IOL used and its effect on the subnormal vision post operatively, in Krishna Hospital, in a period of 18 months. [i]Material and Methods: [/i]183 patients among 1230 who underwent uneventful cataract surgery were diagnosed to have sub-normal vision in our study, over the period of 18 months. All pseudophakic patients, who have undergone uneventful cataract surgery, with normal pre-operative assessment were included in the study. Diabetic and hypertensive patients without any maculopathy were also included. Patients with intra operative complications, traumatic cataract, complicated cataract and pre existing pathology were excluded. Result: Prevalence of sub-normal vision in our study was approximately 14.18%. Among all the causes of sub-normal vision, incidence of posterior capsular opacification (PCO) was maximum with 80.87%. Incidence of PCO is least in foldable IOLs as compare to square edge and non square edge.
