Purpose: To compare the intraoperative complications and results of femtosecond laser assisted cataract surgeries by two different platforms - Catalys and LenSx.Keywords:
Methods: This retrospective, non-randomized, comparative study included the medical records of 579 eyes of 579 patients that underwent femtosecond laser-assisted cataract surgery in 2017 in the Hospital Oftalmologico de Brasilia (HOB) by the same surgeon W.T.H. by Catalys and LenSx platforms. Inclusion criteria were: (1) with presence of a senile cataract, (2) who underwent Femtosecond laser-assisted cataract surgery in 2017 in the HOB by either Catalys or LenSx platform, (3) over 50 years of age, and (4) with none of the following exclusionary factors: existence of any other pathological and/ or neurological condition that could decrease visual acuity, contrast and/or visual field sensitivity, preoperative ophthalmological diseases and complications.
Results: Postoperative corrected distance visual acuity - CDVA - in the Catalys group was 0.04 logMAR vs. LenSx 0.02 logMAR, p = 0.090. Absence of conjunctival hyperemia was 3.2% for Catalys group vs. 2.7% for LenSx group. The amount of docking in the LenSx group was 1.09 times vs. the Catalys group that was 1.17 times. The maximum number of dockings needed to perform the laser in 01 eye in the Catalys group was 5 times, while the maximum amount in the LenSx group was 3 times. Catalys obtained an average of docking time of 165.92 seconds vs. LenSx 132.79 seconds, p <0.01.
Conclusion: Patients who were treated by the LenSx Laser presented greater postprocedure redness, but those who had the Catalys laser application required a greater number and time of docking to have their treatment performed.
