A Prospective Study of Dry Eye in Patients after Manual Small Incision Cataract Surgery

Background: This study aims to assess dry eye indices following cataract surgery. Materials and Methods: A single center descriptive and comparative study was performed. A total of 100 eyes of 100 cases fulfilling the inclusion criteria from 1st June 2017 to 30th May 2018 were enrolled. Out of 100 eyes, 50 eyes each went through manual small incision cataract surgery (MSICS) and phacoemulsification respectively. For objective analysis : schirmer 1 test(ST-I), tear breakup Time(TBUT) along with lissamine Green Surface Staining(LGSS) was performed on pre-operative day, 1st, 4th and 12th week respectively. Ocular Surface Disease Index (OSDI) was done for subjective analysis on pre-operative day and at 12th week. Results: The mean age of the patient was 53.66 ± 7.839 years with 34 (68%) being female in a small incision cataract surgery group. In the phacoemulsification group, mean age was 54.72 ± 7.985 years and 32 (64%) were female. On analyzing the objective dry eye indices: ST-I,TBUT and LGSS at 12thweek was 18.80 ± 7.393 mm, 11.30 ± 5.456 seconds and 1.62 ± 1.193 in Small incision cataract surgery group and 27.10 ± 6.326 mm, 16.60 ± 4.699 seconds and 0.38 ± 0.602 in Phacoemulsification group respectively which was statistically significant. (p< 0.001). Conclusion: Regardless of the type of cataract surgery, dry eye disease is unavoidable affecting both tear quality and quantity postoperatively. In our study, phacoemulsification had lesser effect in dry eye indices than small incision cataract surgery.

Introduction: Cataract is the main cause of bilateral blindness in Nepal. Surgery is the accepted treatment option for cataract with Small incision Cataract Surgery (SICS) and Phacoemusification being the common procedures being performed with comparable results. Corneal astigmatism has been a byproduct of cataract surgery since the first limbal incision was made with improved techniques. Self-sealing scleral pocket incisions are stable and provides early healing, faster visual restoration and more importantly superior astigmatism control. A variety of scleral incisions are being used in manual SICS, with the aim of keeping the post-operative astigmatism to a minimum. Despite having many techniques of scleral incision, there have been only few studies which compares surgical induced astigmatism (SIA) between them Objective: To determine surgical induced astigmatism following frown, chevron and straight incision forms in suture-less small incision cataract surgery(SICS). Methodology: A prospective study was done on a total of 120 patients aged 40years and above with senile cataract. The patients were randomly divided into three groups where each group received specific incision- Straight, Frown and Chevron. SICS with intraocular lens (IOL) implantation was performed. The patients were compared on 2 weeks and 6 weeks post operatively for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and keratometric reading. Surgical induced astigmatism (SIA) was calculated using the SIA calculator version 2.0. The study was analysed using SPSS version 20.0. Results: At 6 weeks UCVA of 6/18-6/6 was attained by 63.41%, 78.94% and 84.61% of patients in group straight, frown and chevron. However about 97% of patients attained BCVA of 6/18-6/6 in all three groups. Mean SIA was least in Chevron group (0.30 D ± 0.16) and was most in the straight group (1.22 D ±0.36) which was statistically significant. Conclusion: Chevron incision induces the least astigmatism compared to frown and straight incision.
