Faster visual recovery and better visual outcomes with femtosecond laser
Creating LASIK flaps with the femtosecond laser resulted in faster visual recovery and better uncorrected visual acuity in a retrospective study of over 65,000 eyes, according to Steve Schallhorn MD.
“The patients whose flaps had been created by femtosecond laser had faster visual recovery, less chance of a loss of best-spectacle corrected vision and lower intraoperative and postoperative complications,” he told delegates attending the XXVII Congress of the ESCRS.
Dr Schallhorn’s study analysed 65,759 consecutively treated eyes for low to moderate myopia and astigmatism. 41,762 eyes had their LASIK flaps created with the IntraLase femtosecond laser and 23,997 eyes had flaps created with a Moria One Use-Plus mechanical microkeratome, with all eyes receiving wavefront-guided LASIK treatments performed with a VISX S4 IR Advance CustomVue excimer laser (AMO).
The refractive accuracy was the same for both groups, said Dr Schallhorn. At all time points measured, the percentage of eyes that achieved a postoperative UCVA of 20/20 or better was significantly higher in the femtosecond laser group than in the mechanical keratome group.
A higher percentage of eyes in the femtosecond laser group also achieved a postoperative UCVA of 20/16. Finally, a lower percentage of eyes in the femtosecond laser group lost two or more lines of BCVA at one week and one month postoperative time point.
