Abstract

Objective: To compare the outcome of Small-incision cataract surgery and Phacoemulsification in term of visual acuity and post operative astigmatism Methods: A retrospective study carried out on 100 eyes of 100 patients from January 2017 to June 2017 at tertiary care hospital. All patients with senile cataract (up to grade IV) operated with SICS or Phacoemulsification were included. Records on all examinations including visual acuity, refraction, biometry, slit lamp biomicroscopy and fundoscopy from the period before surgery up to 6 weeks post-operatively were obtained. Result: The present study reports clinical outcomes of Small-incision cataract surgery and Phacoemulsification up to 6 weeks. Out of 50 patients 34 (68%) patients in the phacoemulsification group and 31 (62.%) of 50 patients in the small-incision group had uncorrected visual acuity better than or equal to 6/18 at 1 week. 41(82%) patients of the phacoemulsification group and 35 (70.%) patients of the small-incision group were better than or equal to 6/18 at the 6-week follow-up for presenting visual activity. Visual acuity improved to 6/18 with best correction in 49 patients (98 %) and 48 (96%) patients respectively. The mode of astigmatism was 0.5 diopters (D) for the phacoemulsification group and 1.5 D for the small-incision group, and the average astigmatism was 1.0 D and 1.3 D, respectively. Conclusions: Both the phacoemulsification and the small-incision techniques are safe and effective for visual rehabilitation of cataract patients, although phacoemulsification gives better uncorrected visual acuity and faster recovery

Highlights

Cataract is the main cause of avoidable blindness all over the world.[1]
Out of 50 patients 34 (68%) patients in the phacoemulsification group and 31 (62.%) of 50 patients in the small-incision group had uncorrected visual acuity better than or equal to 6/18 at 1 week. 41(82%) patients of the phacoemulsification group and 35 (70.%) patients of the small-incision group were better than or equal to 6/18 at the 6-week follow-up for presenting visual activity
The mean age was 60.8 years and 62.7 years for the phacoemulsification and small-incision groups, respectively. 34 of 50 (68%) of the phacoemulsification group and 31 of 50 (62%) of the small-incision group had uncorrected vision 6/18 or better at the 1-week follow-up (Table 1). 41 of 50 (82%) patients in the phacoemulsification group and 35 of 50 (70%) patients in the small-incision group had visual acuity 6/18 without any correction at the 6-week follow-up

Summary

Introduction

Cataract is the main cause of avoidable blindness all over the world.[1]. There are an estimated 9 to 12 million cases of blindness in India, half of which can be attributed to cataract.[2]. 2.8-mm incision, has become popular in the past decade as the method of choice for cataract surgery, superseding conventional extracapsular cataract extraction (ECCE), which involves removing the lens nucleus through a large incision. It is the technique of choice in the Western world and in many centers in developing countries like India. Both techniques use posterior chamber intraocular lens implantation.
