Abstract Details

Purpose:

Review the advantages and the differences of femtosecond laser-assisted cataract surgery (FLACS) following a coaxial or microincision cataract surgery phacoemulsification in the surgical outcome and greater control of cataract surgery.

Setting:

Vissum Corporation, Alicante-Spain

Methods:

Prospective, randomized, observational, comparative case series clinical study was carried out for 50 cataractous eyes selected to be operated with FLACS followed by a bimanual MICS technique(25 patients) (Group A) and a coaxial phacoemulsification technique (25 patients) (Group B). (1) Evaluation of surgical efficiency: (a) Mean Ultrasonic Power(b) Values of EPT (2) Evaluation of the visual and refractive outcomes: (a) Postoperative Spherical Equivalent (b) High-Order Aberration (Corneal and Internal) (c) Visual Efficacy Index (3) Other examinations were evaluated by assessing the corneal pachymetry, endothelial cell count, macular thickness and incidents during and after surgery.

Results:

The efficacy index for FemtoMICS was 160.2 and 149% for Femto Coaxial measured at 1 month after surgery. No significant differences were found in corneal pachymetry, endothelial cell count and macular thickness. The mean total corneal HOAs (6mm) both, before and after surgery were 0.6 ±0.4 and 0.66 ±0.2mm, respectively (P=0.1). The mean value for internal coma (4mm) for both procedures was 0.13 mm. The visual index for FemtoMICS was 160.2 and 149%for FemtoCoaxial measured at 1 month after surgery. The mean power of ultrasound for MICS was 1.8± 0.9% and for 2.2mm incisions was 14.7±4.9% (P<0.001). EPT values for MICS and 2.2mm incisions were 1.5±0.9 and 4.5±2.9 s. (P=0.002), respectively.

Conclusions:

FemtoMICS appears to be surgically and statistically more efficient than the FemtoCoaxial technique and Femtoincisions prove to be stable and do not change the corneal high-order aberration significantly with favorable results of the triplanar configuration.
