Purpose: To determine the safety and efficacy of four different femtosecond laser cataract platforms; The Bausch and Lomb Victu Alcon LenSX, Optimedica Catalys and the Ziemer Z8 femtosecond laser platforms.

Method: 50 Eyes underwent laser cataract extraction with one of three laser platforms: Alcon Lensx, Technolas Victus, Optimedica Catalys, Ziemer Z8 or manual cataract extraction. Capsulotomies were created with the laser and extracted from the eye as one piece, placed into a vial of saline. Electron microscopy was performed on each capsulotomy. Post operative results including, vision, refraction and IOP were monitored.

Results: At the 3 months post operative visit, all groups demonstrated on average an improvement in uncorrected distance vision to 6/7.5, there was no statistical difference between the groups. There was also no difference in rates of complications between the four platforms. However, electron microscopy demonstrated that the fluid filled interface lasers appeared to have an increase in tags than the contact interface laser.

Conclusion: Femtosecond laser cataract platforms appear to be a safe and effective method for use in cataract surgeries and although there appears to be no statistically difference in patient results, electron microscopy demonstrates some difference in the quality of the capsulorhexis.
