Abstract
Background:Surgically induced astigmatism (SIA) is astigmatism that is created by incisions in cataract surgery; change in both the power and to a lesser degree, orientation of the principal meridians following a corneal incision. Prese nt study was aimed to study change in vision and astigmatic refractive error postoperativelyin patientsundergoing clear corneal phacoemulsificationsurgerywithfoldableintraocularlens.Material And Methods:Present study was hospital based, prospective, observational study, conducted in patients posted for phacoemulsification cataract surgery with foldable IOL with clear cornea and regular astigmatism on keratometry, with preoperative astigmatism more than or equal to 0.5D on keratometry, willing to participate in study.Result:In present study,44 eyes of 44 patients were considered for study. Mean age of the patient is 56.98 ± 5.98 years. There were 29 males and 15 females. Right eye surgery was done in 18 eyes and left eye surgery was done in 26 eyes. Refractive acceptance preoperatively was 0.50 D to 2.0 D. Mean IOL power was 22.7 ± 0.801. Preoperatively mainly eyes had best visual activity between 6/24 to 6/18 while visual activity range from 6/60 to 6/12. Improved vision postoperatively day 90th where vision was 6/6 unaided in 24 eyes out of44 eyes and 6/9 in 14 eyes respectively. Majority of patients had Preop Keratometric Difference (K1-K2) of 1.5 D, all required LRI Incisions length of 4 cloc k hours (60°). On postoperative 90th day, improved dioptric difference by automated keratometry ascompared to preoperative values. LRI was slightly more effective in patients above 50 years as compared to in patients below 50 years.Conclusion:In patientsundergoing clearcornealphacoemulsification surgery with foldable intra-ocular lens, postoperatively improved vision and reduced astigmatic refractive error is noted.
