Abstract Details

Purpose:

The aim of our prospective clinical trial was to investigate the clinical outcome of the high frequency femtosecond laser in cataract surgery compared to the conventional procedure

Setting:

Eye Clinic ORASIS, Swiss Eye Reseach Foundation, Reinach AG, Switzerland

Methods:

The study included 130 eyes from 130 patients: 68 treated with femtosecond laser-assisted cataract surgery (FLACS) using the FEMTO LDV Z8 and 62 treated with conventional phacoemulsification. Capsulotomy and lens fragmentation in the laser group were performed with the high frequency femtosecond laser system, which employs a new, low-energy, high repetition rate laser process for cataract surgery. In the conventional group, the capsulotomy was performed by a cystotome, and lens fragmentation was achieved by the stop-and-chop

Results:

The intended capsulotomy diameter was in group 1, high frequency femtosecond laser, significant more precise (p<0.001) than in group 2, conventional procedure. The mean phacoemulsification time in Group 1 was 1.9 ± 2.25 and in Group 2, 2.3 ± 2.41 s which is significant (p = 0.042). The effective phacoemulsification time (EPT) in Group 1 was found to be 1.48 ± 1.80 s and in Group 2 1.81 ± 1.93 s, which is significant (p = 0.044). Overall surgery time in Group 1 was 7.5 ± 1.22 min (range: 5–12 min) and 6.6 ± 1.76 min (range: 4.6–12 min) in Group 2, that is slightly significant (p = 0.048). The total follow-up time was three months

Conclusions:

FLACS with the high-frequency femtosecond laser system was characterized by complete and reproducible precise capsulotomy and highly effective lens fragmentation. The FLACS shows a significant less need of phacoemulsification time and EPT compared to conventional procedure what is presumed to be safer
