Abstract

Aim of the study: Study of comparison of postoperative astigmatism in small incision cataract surgery depending on size and shape of incision
Materials and Methods: A prospective study of 50 eyes of 50 patients who underwent manual SICS under local anaesthesia between December 2020 and May 2021 conducted by single surgeon and followed up on post op day 1 day 7 and 6 weeks. Patients selected were having grade 1 to 2 nuclear sclerosis the size and shape of incision was decided depending upon the grade of cataract. On follow ups thorough ocular examination was done especially looking for corrected visual acuity and correction needed for that. Keratometry was done in each follow up visits. At the end surgically induced astigmatism (SIA) was calculated.
Results: Surgically Induced Astigmatism (SIA) calculated by SIA calculator SIA was 0.5 - 1 D in 38 patients with frown incision of 4 to 5mm,1.0 - 1.5 D in 10 patients with frown incision size of 5 to 6mm 2D in patients with straight incision size of 6mm and more In all cases.
Conclusion: The less average SIA was noted in group with smaller incision of about 4 to 5mm. Frown superior incision has got added advantage of early wound stabilization than straight incision. It is possible to reduce the amount of post-operative astigmatism significantly by choosing the incision shape and size.
