COMPARISON OF POST OP ASTIGMATISM AFTER SUTURELESS CATARACT EXTRACTION SURGERY WITH INCISION OF 3.5MM VERSES 6MM USING SURGICAL DATA

Background: Less instrumental expenses and disposability of small and big incision cataract surgery is beneficial. At point it appears a better and suitable treatment for advanced and mature cataract. Superiority declaration of surgically induced astigmatism (SIA) has therefore become a public health problem, and SIA analysis therefore important as its other procedures are. Such kind of studies like present is limited in Pakistan; therefore, we designed this study with the aim to compare the post op SIA with suture less 3.5mm (Phacoemulcification) & 6 mm incision surgery that is SICS (Small Incision Cataract Surgery). Methods: Study design: Randomized Controlled Trial. Setting: LRBT free eye care hospital Chiniot center. Duration: 6 months' duration. Procedure: Post-Operative cataract patients were assessed for the astigmatism and surgical efficacy and related adverse events after suture less cataract extraction by means of, a) with incision size 6 mm or more (SICS) b) with incision size 3.5 mm or more (Phaco). The exclusion criteria include all patients with renal failure, past surgical history and heart disease and all other eye diseases whereas all the patients of both genders above 18 years of age with suture less cataract extraction surgery were included. Results: The records of total 140 patients were retrieved via hospital record system. The mean age of the patients was 54 + 8.9 with range 18-60. 25 (31.3%) of the patient were in the age category of 36 to 45. The visual activity was quantified as zero when it was <1/60 to PL+, as 1 when it is less than 3/60 to 1/60, As 2 when it is less than 6/60 to 3/60, as 3 when it is Less than 6/18 to 6/60 and 4 when it is 6/6 to 6/18. With repeated visits post operatively the uncorrected visual acuity has increased and the maximum of the increase was observed in group 2 patients with 3.5 mm incision. Conclusion: We may conclude that SIA is less likely to be occurring in the suture less 3.5mm surgery. However, 6mm SICS is more cost effective. Key words: Cataract, surgically induced astigmatism (SIA), suture less surgery SICS (Small incision Cataract Surgery), Phaco (Phacoemulsification)
