Efficacy and Safety of Femtosecond Laser-Assisted Lens Surgery With 2 Personal Interfaces
Narrative Responses:
Purpose
Evaluation of effectiveness and safety of femtosecond laser-assisted lens surgery.
Methods
In this consecutive case series, two hundred eyes underwent femtosecond laser-assisted (LenSx, Alcon) lens surgery between November 2012 and June 2013. Group 1 (85 eyes: 60 cataract, 25 refractive lens exchange (RLE)) was treated with a curved direct contact interface, in group 2 (115 eyes: 72 cataract, 43 RLE) a modified interface using an additional soft contact lens (SoftFit®, Alcon) was used. Phacoemulsification was performed followed by IOL implantation in all eyes. The degree of lens opacity was measured preoperatively with Scheimpflug imaging. Primary endpoints were the effective phacoemulsification time (EPT), the average laser treatment time and intraoperative complications.
Results
EPT in group 1 was 1.62 ± 1.12 s and in group 2 1.66 ± 0.92 s. The laser treatment lasted on average 48.90 ± 2.45 s (group 1) and 49.70 ± 2.87 s (group 2), with an averaged lens fragmentation thickness of 3401 ± 401 µm (all groups). In four cases of group 1 a second docking was necessary. One anterior capsule tear, 39 cases with corneal wrincles and 21 cases with incomplete corneal incisions were documented in group 1. In group 2 only 9 cases with incomplete corneal incisions were documented.
Conclusion
The optimized new personal interface led to a significant reduction in complication rate and enhanced efficacy of the femtosecond laser-assisted lens surgery.
