STUDY ON VISUAL OUTCOME FOLLOWING TORIC IOL IMPLANTATION IN CATARACT PATIENTS WITH ASTIGMATISM
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2017, Vol 4, Issue 16
Abstract
BACKGROUND The aim of this study was to determine the efficacy of toric IOL placement in astigmatic patients with immature cataract. MATERIALS AND METHODS This prospective study included 20 eyes of 20 patients with a visually significant cataract and corneal astigmatism ≥1.00 D. All patients underwent phacoemulsification and implantation of SP TORIC IOL. The unaided visual acuity and best corrected visual acuity 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. RESULTS Post-operative examination was conducted at day 1, day 3, after 1st week, and 1 month later. The average cylinder in IOL plane 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. One month postoperatively, the average Log MAR is 0.2±0.21SD. And the difference LOG MAR is 0.61±0.31SD. Inference: A significant improvement was noted after surgery in Log MAR values. Among 20 patients, 18 (90%) patients had improved visual acuity, 2 (10%) patients didn’t show any visual improvement due to misalignment of IOL axis. There were no significant intraoperative complications among the study population. CONCLUSION Implantation of SPTORIC IOL is an effective and safe method to correct corneal astigmatism during cataract surgery.
