Study: Effective lens position advances accuracy
Findings from a prospective study demonstrate that capsulotomy creation using a proprietary femtosecond laser system improves the predictability of effective lens position to deliver increased refractive accuracy and better visual acuity outcomes.
Orlando, FL-Findings from a prospective study demonstrate that capsulotomy creation using a proprietary femtosecond laser system (LenSx, Alcon Laboratories) improves the predictability of effective lens position (ELP) to deliver increased refractive accuracy and better visual acuity outcomes, said Robert J. Cionni, MD, at Refractive Surgery Subspecialty Day during the annual meeting of the International Society of Refractive Surgery/American Academy of Ophthalmology.
In addition, the mean absolute error between the attempted and achieved refraction was significantly less in eyes that had the laser capsulotomy compared with the manual capsulorhexis group, 0.26 ± 0.16 D versus 0.34 ± 0.21 D, and the 1-month refraction was within 0.25 D of attempted target in a significantly higher proportion of eyes in the femtosecond laser group compared with the controls undergoing manual capsulorhexis, 77% versus 54%. These differences translated into better functional outcomes for the laser group; 73% of eyes with a laser capsulotomy compared with 46% of controls had uncorrected visual acuity of 20/20 or better at 1 month.
