The measures of interest in the current analysis were the change in orientation of the IOL between 1 day, 1 month and 3 months postoperative. Orientation was measured at the microscope on the day of surgery, and with the slit lamp at all other visits. Day 1, 1-month and 3-month images of the lens orientation were captured with a slit lamp camera. Differences in orientation were recorded and analyzed.Results: A total of 150 eyes had IOL orientation data available. Image analysis showed mean absolute lens orientation changes from 1 day to 1 month and 3 months of less than 2 degrees. The percentage of lenses exhibiting rotation of ≤ 5 degrees between any measured time points was 97% or higher. Results were similar, but significantly more variable, when IOL orientation was measured at the slit lamp.Conclusion: The toric EDOF lens evaluated here demonstrated rotational stability that exceeded the prior ANSI standard. The best method to determine IOL orientation changes was through image analysis. &emsp;Keywords: TECNIS symfony toric, toric IOL, rotational stabilitySandoval HPLane SSlade SDonnenfeld EDPotvin RSolomon KDDove Medical Pressarticletecnis symfony torictoric iolrotational stabilityOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 2405-2410 (2020)
