Abstract Details

Purpose:

To report our experience using the new Z8 laser system for laser assisted cataract surgery (FLACS) and to provide a sample or the tendency in terms of performance and safety using this new technology

Setting:

Swiss Eye Research Foundation, Eye Clinic ORASIS, Reinach, Aargau, Switzerland

Methods:

Prospective case series. Fourteen patients were subjected to unilateral FLACS. Capsulotomy and lens fragmentation were performed with the aid of LDV Z8 femtosecond laser system. Ease of phacoemulsification (in 4-grade scale), completeness of capsulotomy (in 10-grade scale), time for preparation of femtosecond laser (minutes), effective phacoemulsification time (seconds), total time of surgery (minutes) and safety of the procedure were evaluated.

Results:

Ease of fragmentation and completeness of capsulotomy were estimated at 3.9 and 9.9, respectively. The preparation time for the femtosecond was 3.6±0.7, effective phacoemulsification time was 2.5±3.1 and total time of femtosecond-assisted cataract surgery procedure was 16.3±4.5. No major complications were observed. Approximately 42% of all patients (6/14) presented Descemet folds directly postoperatively.

Conclusions:

FLACS with the LDV Z8 system was characterized by a complete capsulotomy and a highly effective and reproducible lens fragmentation. The safety level of the procedure was very good as it was perceived from the surgeon operating in this observational case series. The ratio of costs over benefit should be further debated by assessing the results of a major prospective study, that is required for a valid evaluation of the efficiency and safety of LDV Z8 laser system and of FLACS in general.
