Abstract Details

Purpose:

To compare the nucleus removal time (NRT), cumulative dissipated energy (CDE) and consumed balanced salt solution (BSS) outcomes of femtosecond assisted cataract surgery (FLACS) performed by cornea attendings and cornea fellows using 3 different laser platforms with traditional surgery.

Setting:

Bascom Palmer Eye Institute, Miller School of Medicine, Miami, Florida, USA.

Methods:

In this prospective, comparative, non-randomized clinical study, four hundred and seventy patients scheduled to undergo cataract surgery and 444 eyes were included. Patients underwent surgery using either FLACS (three Femtosecond platforms were used: Catalys, LenSx or Victus), or traditional phacoemulsification (manual technique) by 3 cornea attendings and 4 cornea fellows using the same phacoemulsification platform (Centurion). Main Outcome Measures: Cataract grade, NRT, CDE and consumed BSS in all procedures.

Results:

In the attending group, NRT and consumed BSS were significantly lower (p<0.005) when using the Catalys system compared to the traditional surgery and CDE was non-significantly lower with each FLACS compared to traditional surgery (p>0.05). In the fellow group, NRT was significantly lower when using the Catalys (p=0.002), LenSx (p=0.04) and Victus (p=0.009) systems compared to the traditional surgery, CDE and consumed BSS were non-significantly lower with each FLACS compared to traditional surgery (p>0.05). On the other hand, all 3 parameters were significantly higher in fellow group compared to attending group in traditional cases, however in FLACS cases, only consumed BSS was significantly higher in fellow group compared to attending group when using the Catalys system.

Conclusions:

FLACS seems to achieve lower NRT, CDE and consumed BSS when compared to traditional surgery independent to the surgeons’ level of experience.
