Abstract Details

Purpose:

To compare the effectiveness and safety of Femtosecond Laser Assisted Cataract Surgery (FLACS) in the fragmentation of the nucleus and anterior capsulotomy compared with conventional cataract surgery .

Setting:

Clinica La Luz, Lima. Perú.

Methods:

60 consecutive eyes will perform random fragmentation of the nucleus and anterior capsulotomy assisted by femtosecond laser (Catalys -Optimedica , Santa Clara, CA , USA) guided by optical coherence tomography. In the conventional phacoemulsification surgery we performed manual continuous circular capsulorhexis. Both procedures were completed with standard phacoemulsification and intraocular lens placement. The measured results were effective phacoemulsification time (EPT), average phaco power, average phaco time, volume balanced solution (BSS), precision capsulotomy and adverse events.

Results:

30 eyes underwent femtosecond laser procedure and 30 eyes manual cataract surgery. The EPT was significantly lower in the laser group 5.77SD ± 5.2 seconds, in the manual group 7.7 ± 6.0 seconds, p < 0.025 ; 6 patients in the laser group vs 1 case in the manual phaco group had phaco zero p < 0.005. There was significant difference in average phaco energy of 13.8 % ± 10.3 % in the laser group and 20.3 % ± 8.1 % in the manual group p < 0.001. There was no significant difference in the average phacotime, BSS volume or adverse events. 100 % of cases treated with laser capsulotomy was performed complete.

Conclusions:

The femtosecond laser has been proven safe and effective in cataract surgery, reducing the EPT and mean phaco energy during the fragmentation of the nucleuse and provides an accurate and reproducible capsulotomy .
