Postoperative Astigmatism

Objective: Globally a significant proportion of treatable blindness is caused by cataract, especially in India and southeast Asia. Treatment of cataract is surgical correction with intraocular lens implantation. The main drawback of surgical correction is induction of postoperative astigmatism in patients. The aim of this study was to compare the degree of astigmatism in manual small incision cataract surgery and phacoemulsification 3 mo postoperatively Methods: The study was a retrospective case study on postoperative corneal astigmatism after cataract surgery. It was conducted in a tertiary care hospital in Thandalam, Tamil Nadu. A total of 100 patients were selected and divided into two groups, group A (=50) underwent phacoemulsification and group B (=50) underwent manual small incision cataract surgery. Preoperative astigmatic status of the patients was noted from patient records. Both groups were evaluated 3 mo postoperatively using automated keratometry. The data collected was analyzed using Microsoft Excel Independent T test, p<0.05 was considered statistically significant. Power of the study was 80% with an alpha error of 5%. Results: Mean postoperative astigmatism at 3 mo was 0.91±0.255D and 0.34±0.110D due to manual small incision cataract surgery and phacoemulsification, respectively. Conclusion: Postoperative astigmatism was greater in manual small incision cataract surgery than phacoemulsification. Improvement in preoperative astigmatism was seen in patients who underwent superotemporal incision phacoemulsification

Introduction: Proper preoperative biometry in cataract surgery provides expected postoperative uncorrected visual outcome. Astigmatism is one of the major problems to achieve best postoperative unaided visual acuity. Aims: To determine the distribution of biometric parameter and unaided visual outcome in the cataract patients operated at Nepalgunj medical college, Banke, Nepal. Methods: The patients who underwent cataract surgery between January 2019 and December 2020 at Nepalgunj medical college were studied. Patient’s demographic parameter, keratometric value, anterior chamber depth, lens thickness and axial length data, type of surgery, preoperative and post-operative visual acuity and other clinical details were collected and analyzed. Results: This study enrolled 261 eyes of 261 patients who had undergone cataract surgery. The mean age of patients was 60.8 ± 14.62 years. The mean corneal astigmatism was 1.30±1.43 D. Corneal astigmatism was higher than 1.00 D in almost 40% of cases. With-therule astigmatism was the most common type (46.4%) of astigmatism observed in this study. The mean average keratometry was 44.83±2.05 D. The mean preoperative LogMAR VA of 1.52±0.83 improved to 0.48 ± 0.48 postoperatively without statistically significant differences between manual small incision cataract surgery and phacoemulsification technique (p=0.496). Conclusion: The biometric data helps to improve surgical procedure and select most appropriate intraocular lens to attain maximal postoperative uncorrected visual acuity following cataract surgery. This study found superior convention incision is better for cataract surgery with equivalent visual outcome following manual small incision cataract surgery and phacoemulsification.

Purpose. To assess safety and efficacy of temporal manual small incision cataract surgery (SICS) in context to visual outcome, astigmatism, and complications. Methods. This involved sclerocorneal tunnel, capsulotomy and hydrodissection. The incision was made with number 11 disposable surgical blade (costing Indian Rs. 2.50, $0.05). Nucleus extraction was done by phaco-sandwich method with the help of vectis and dialer. Posterior chamber intraocular lens implantation was done according to biometric findings. A record of intraoperative and postoperative complications was made. The final postoperative assessment of astigmatism was done with spectacle correction on the 45th day as per the refraction findings. Results. Two thousand eyes were operated by temporal, manual small incision sutureless technique. Uncorrected visual acuity was ≥6/18 in 1636 (81.7%) patients on the first postoperative day, in 1652 (82.6%) patients at 2 weeks, and in 1732 (88.6%) patients at 6 weeks. Best-corrected visual acuity (BCVA) ≥6/18 was achieved in 1868 (93.4%) patients at 6 weeks, with 46 (2.3%) having BCVA <6/60, 24 (1.2%) of whom had preexisting retinal pathology. At 6 weeks, 1876 (93.8%) eyes had with-the-rule and 134 (6.2%) against-the-rule astigmatism (mean 0.7±1.25 D). Iris prolapse was noted in 3 (0.15%), wound leak in 3 (0.15%), and transient corneal edema in 136 (6.8%) eyes. Average surgery time was 6 minutes. Conclusions. Temporal SICS with number 11 disposable surgical blade and nucleus delivery by phaco-sandwich method gave excellent outcome with minimal astigmatism and low complication rate at economic cost.
