Abstract Details


To identify measurable differences between two femtosecond cataract lasers in use in a single private ambulatory surgical center.


Private Practice, Hoopes Vision, Draper, Utah USA.


In this randomized, patient-masked prospective series, patients with bilateral cataracts undergo surgery in one eye with the LenSx (Alcon), and in the fellow eye with the Catalys (Optimedica). All surgeries are performed by two surgeons. Differences in time of docking, duration of treatment with laser, completeness of corneal incisions, completeness of capsulotomy, phacoemulsification time and difficulty of cortical removal are tabulated.


Comparison of these metrics across two different femtosecond cataract laser platforms shows statistically significant differences in each of the categories tabulated. Femtophacoemulsification with the Catalys laser yielded significantly better parameters than treatment with the LenSx.


Significant differences in femtosecond laser-assisted cataract surgery exist between the Alcon LenSx and the Optimedica Catalys. Results were similar between both surgeons.
