Abstract: Title: "A Prospective Observational Study To Assess The Efficacy Of Image Guided System - Verion As a Predictor Of Post Operative Refractive Outcome In Cataract Surgery" Methods: A Hospital based, prospective observational study on patients who presented with diminution vision due to cataract with sample size of 100 eyes carried out from December 2019 to May 2021 at Rotary Eye Institute, Navsari. After complete history taking , complete ophthalmic examination was done, blood Investigations were done. IOL was implanted according to Verion calculations. The post-operative final refractive error was assessed by objective refraction on Topcon autokeratorefractometer along with subjective testing and was compared with Verion predicted post-operative refractive error. Results: In our study, IOL Master and the VERION systems have a place in the prediction of postoperative spherical cylinder and cylinder axis outcomes compared with Autokeretorefractometer (Topcon KR 800) readings (objectively) after cataract surgery, as post- operatively there is no statistical difference between VERION expected spherical cylinder, cylinder axis and Post-operative Autokeratorefractometer (Topcon KR 800) spherical cylinder and cylinder axis. Conclusions- The Verion is the new technology to give reliable expected refractive outcome. The Verion and IOL Master together can be used for achieving near emmetropia post operatively, and for better suggestion of IOL power. In addition to its role in astigmatism management, the VERION may be used to help refine postoperative spherical refractive predictions from the IOLMaster. The VERION system has high repeatability and agreement with the IOLMaster, making it suitable as an alternative tool in clinical practice.
