Optegra Eye Sciences has reported that its first ever study into the long term benefits of lens exchange surgery was a success.

The study reviewed data from 12,990 refractive lens exchange procedures that included eight different lenses of varying designs and focusing power between January 1 and June 30, 2011. The results showed that postoperative monocular distance vision was 20/40 or better in 96.2% of eyes and 20/20 or better in 60.8% of eyes, and binocular vision was 20/40 or better in 99.5% of eyes and 20/20 or better in 77.3%.

Dr. Clare O’Donnell, leader of the study and head of Optegra Eye Sciences, said: ‘The rationale for this study was to reflect our interest in and commitment to the long-term care of our patients, particularly as there is an increasing desire from many to become spectacle independent. While there are many studies capturing immediate outcomes and also one year on, this is the first to review patient outcomes and satisfaction up to seven years after treatment. The results were very encouraging, with 88% of respondents saying that knowing what they know now, they would have treatment again.’
