Comparison of Refractive Outcomes of Traditional Cataract Surgery and Femtosecond Laser–Assisted Cataract Surgery Performed on 2 Laser Platforms
To compare postoperative refractive outcomes between traditional cataract surgery and femtosecond laser-assisted cataract surgery performed on the LenSx (Alcon) and Catalys (AMO) laser platforms.
Cataract surgery performed by 2 surgeons (SY and KD) at the Bascom Palmer Eye Institute between August 2013 and August 2014 were divided into 3 groups: traditional, LenSx, and Catalys groups. The 3 groups were compared based on visual and refractive outcomes. 438 cases were identified, 295(67 %) of cases were traditional, 91(21%) were LenSx and 51(12%) were Catalys cases.
Final spherical equivalent achieved was compared between the 3 groups and were found to be similar (0.51 D traditional, 0.36 D LenSx, 0.43 D Catalys, p=0.22). Attempted versus achieved spherical equivalents, BCVA and UCVA at post-op 1 month were compared. Patients undergoing astigmatism correction with TORIC IOLs and LRIs were compared to traditional cataract surgery (without astigmatism correction).
Refractive outcomes between traditional cataract surgery and laser-assisted cataract surgery with LenSx and Catalys platforms were not found to be statistically significantly different. When patients underwent astigmatism correction (with LRIs or TORIC IOLs), refractive outcomes improved.
