Abstract Details



Purpose:

Cataract surgery using Femtosecond Laser technology aims to be the next important ophthalmic advancement to enhance safety and predictability of the procedure. The purpose of this study is to report the outcomes of a single surgeons experience with his first 200 consecutive cataract cases using the Lensar femtosecond laser platform

Setting:

The Eye Institute of West Florida

Methods:

A prospective study of the safety, reproducibility, and predictability of the first 200 consecutive eyes undergoing cataract surgery by a single surgeon with the LensAR Femtosecond laser are reported . Capsulotomy, Lens cube fragmentation, and corneal relaxing incisions were performed. Data collected included capsulotomy centration and completeness, effective phaco time and any complications . For effective phaco time, data was compared to a cohort of non femtosecond laser treated eyes.

Results:

Ninety-five percent (191/200) of cases were completed without complication and of those cases (100%) achieved ideal capsulotomy. The capsulotomy was complete, round and centered to the pupil as planned in all cases. Four cases had tight orbits which were unable to be docked and Five case experienced suction break due to patient movement. However, no intraoperative complications or adverse events induced by the laser occurred in any of the cases. In addition, a greater than 50% reduction in effective phacoemulsification time (EPT) compared to a similar cohort of eyes undergoing routine cataract surgery without femtosecond laser lens fragmentation was noted.

Conclusions:

This initial experience of 200 cases regarding the safety and predictability of the femtosecond laser technique using the LensAr platform is excellent, enabling successful capsulotomies in all cases, shortening the phaco time,and reducing the phaco energy utilized, therefore making the more complicated aspects of cataract surgery easier and safer. No intraoperative complications, which might be associated with the LensAR laser system, occurred. Femtosecond cataract surgery is an important and viable addition to the surgical armamentarium available to the ophthalmic surgeon. Additional studies of femtosecond laser-assisted cataract surgery should be conducted to assess if this technology proves to be superior to conventional cataract surgery FINANCIAL INTEREST: One of more of the authors... is employed by a forNONEprofit company with an interest in the subject of the presentation
