The efficacy of Toric IOL in comparison to LRI in correcting pre-existing astigmatism in phacoemulsification
Journal Title: Medpulse International Journal of Ophthalmology - Year 2018, Vol 8, Issue 1
Abstract
Background: With advances in cataract procedures and IOL technology, minimizing postoperative astigmatismis becoming increasingly important. Cataract surgery has become a “true refractive surgery” because of the meticulous calculation of IOL power and correction of the pre-existing astigmatism. Hence considering the need of the hour present study was designed to find the most accurate method to correct the preexisting astigmatism. Material and Method: It was a Prospective interventional study in which the patients were divided into two group. In Group 1 Implantation of Toric IOL was done after cataract surgery in 20 eyes. In Group 2 Spherical IOL implantation combined with limbal relaxing incision was done in 20 eyes. Results: The correction of pre-existing astigmatism is more effectively achieved by the use of Toric IOL. The use of a Toric IOL reduces the complexity of the surgical procedure eliminating the need for additional incision. The results of LRI are affected by multiple factors including age, preop K, peripheral pachymetry, and inter-patient variability in corneal healing. Treating lower amounts of astigmatism, results are similar in both LRI and Toric IOL groups however in eyes with greater astigmatism, the Toric IOL was more accurate and more predictable. Conclusion: Both LRIs and the Toric IOL represent effective methods for correcting low to moderate amounts of corneal astigmatism.Considering the results of this study, implantation of Toric IOL is possibly the better option.
