STUDY ON VISUAL OUTCOME FOLLOWING TORIC IOL IMPLANTATION IN CATARACT PATIENTS WITH ASTIGMATISM

BACKGROUND \nThe aim of this study was to determine the efficacy of toric IOL placement in astigmatic patients with immature cataract. \nMATERIALS AND METHODS \nThis prospective study included 20 eyes of 20 patients with a visually significant cataract and corneal astigmatism ≥1.00 D. All \npatients underwent phacoemulsification and implantation of SP TORIC IOL. The unaided visual acuity and best corrected visual \nacuity were evaluated. Toric IOL axis and alignment was measured with slit lamp examination. The IOL manufacturer’s webbased toric calculator was used to determine the required cylinder power and axis for the IOL that was going to be implanted. \nRESULTS \nPost-operative examination was conducted at day 1, day 3, after 1st week, and 1 month later. The average cylinder in IOL \nplane is 3.04D±0.66SD. and average cylinder in corneal plane is 2.14D±0.38. The average pre op LOG MAR was 0.8±0.2SD. \nOne month postoperatively, the average Log MAR is 0.2±0.21SD. And the difference LOG MAR is 0.61±0.31SD. Inference: A \nsignificant improvement was noted after surgery in Log MAR values. Among 20 patients, 18 (90%) patients had improved visual \nacuity, 2 (10%) patients didn’t show any visual improvement due to misalignment of IOL axis. There were no significant \nintraoperative complications among the study population. \nCONCLUSION \nImplantation of SPTORIC IOL is an effective and safe method to correct corneal astigmatism during cataract surgery.
