Abstract: (6862 Views)
Post cataract operation visual acuity affected by the astigmatism which it is influenced by several factors including the suture material. This study compares 8-0 vicryl (V) and 10-0 Nylon (N) suture material for induced astigmatism and its decay in time in cataract operation. This is retrospective study of consequetive case series that underwent cataract extraction and intraocular lens implantation by one surgeon with scleral flap incision and horizontal suturing. Exclusion criteria included history of pre and postop ocular surgery topical or systemic steroid use, diabetes and less than 40 years old age. From the file of the patient age, sex, visual acuity and Keratometry of pre-op and one week, one month, 3 months and 6 months post op datas kind of sature and computer transferred to a computure. According to the type and number of suture material patients divided into V. and N. groups, and according to induced astigmatism divided into No, with the rule (WTR) AND AGAINST THE RULE (ATR) astigmatism and underwent statistical analysis by X2 tests. From 345 eyes that has complete 6-70 (Mean 18±3.2) month fallowup, 162 has been sutured by V and 183 by N. Age range was 41 to 85 (Mean 62.56±4.2) years and 47% were male. At one week post op 89.5% of V and 91.2% of N group had WTRA and no ATRA. At one month post op 38.2% of V and 33.8% of N had WTRA while 35.8% of V and 36.6% of N developed ATRA. After 3 months 3.7% of V and 4.9% of N had WTRA while 81.4% of V and 83.5% of N had ATRA. After 6 months and on final, visit 2.4% of V and 3.2% of N had WTRA and 80.8% of V and 83.6% of N group were ATRA. For each period of time there was no significant statistical differences between V and N (P>0.05) but there was statistically significant differences between preop and one week, one week and one month, one month and 3 months (P<0.05) but not between 3 months and 6 months astigmatism. There is no differences in induced astigmatism and it decay in cataract extration by scleral flap incisionn and horizontal suturing between V. and N.
