Abstract
A hospital based study was conducted on 100 eyes at a tertiary care centre, that underwent clear corneal phacoemulcification with temporal incision and implantation of intraocular lens implantation. 50 eyes had rigid and 50 had foldable intraocular lens implantation irrespective of the type of astigmatism. The length of incision in patients with foldable was 2.8mm and was extended to 5.5mm in patients with rigid intraocular lens. Keratometric and Surgically induced astigmatism was assessed on day 1, 7 and 42. We found that there was no statistically significant difference in visual outcome and surgically induced astigmatism in two groups on day 1, 7 and 42. There was no significant difference in Keratometric Astigmatism in two groups on day1 and 7. The Keratometric Astigmatism was significantly different in two groups on day 42 (P value-0.007), the patients with rigid intraocular lens implant had significantly more astigmatism on day 42 than those with foldable intraocular lens implant. Pre-operatively majority of the patients had against the rule type of astigmatism. It was observed that there was a shift from against the rule type to with the rule type of astigmatism in both the groups. The shift in the type of astigmatism was found to be more in patients with rigid intraocular lens implantation than those with foldable intraocular lens implantation (4%). We found that rigid intraocular lens implants which are cost effective can be beneficial in low socioeconomic set up with no potential disadvantages and side effects.
