Abstract Details

Purpose:

Femtosecond assisted laser cataract surgery provides surgeons an exciting new option to potentially improve patient outcomes and safety. The aim of this study is to evaluate the efficacy and safety of femtosecond laser-assisted cataract surgery (FLACS) in the treatment of cataract in special situations.

Setting:

The study was done at Universitary Hospital La Fe, Valencia. Spain

Methods:

We performed FLACS (Victus) with posterior chamber lens implantation in patients after endothelial keratoplasty, penetrating keratoplasty, phakic lens implantation and intracorneal rings implantation. Anterior segment morphologic changes were visualized with a Scheimpflug camera (Pentacam), and anterior segment Optical Coherence Tomography.

Results:

FLACS in this special cases reduced mean phaco energy and effective phacoemulsification time required in the surgery reserving endothelial cells in postoperative transplant corneal. Central corneal thickness was significantly lower in FLACS at 1 day of follow-up (but comparable at 1 week of follow-up or longer). FLACS achieved a better visual outcome at postoperative 1 week and 6 months. The incidences of intraoperative anterior capsule tear, postoperative macular edema, elevated intraocular pressure and graft failure were similar.

Conclusions:

As the femtosecond laser was successfully introduced in cataract surgery, we applied this technology in special eyes that had a previous surgery. Femtosecond laser treatment can reduce energy and effective phacoemulsification time, which may reduce the heat damage to ocular tissues by ultrasound. This novel technique might be beneficial for patients with dense cataract and/or low preoperative endothelial cell values.
