Abstract Details

Purpose:

To report changes in endothelial cell density (ECD) and corneal thickness measurements in patients having standard phacoemulsification compared with femtosecond laser-assisted cataract surgery (FLACS).

Setting:

Cornea division, Wilmer Eye Institute, Johns Hopkins University School of Medicine.

Methods:

In this prospective, randomized, controlled study one eye of each patient had standard phacoemulsification (control group) and the other eye had FLACS (study group), both with intraocular lens implantation. In the study group corneal incisions, capsulotomy, and lens fragmentation were performed by means of femtosecond laser. Noncontact endothelial microscopy and corneal pachymetry were measured pre-operatively and 1 day, 1 week, 1 month and 3 months post-operatively.

Results:

124 eyes of 62 patients were analyzed. The mean endothelial cell loss was 9.1%±15.3% 1 week post-operatively and 11.5%±15.7% 3 months post-operatively in the study group and 4.3%±14.7% and 8%±18.7%, respectively, in the control group. The mean change in corneal thickness from the pre-operative values was -4.1%±8% at 1 week and 0.4%±5.2% at 3 months in the study group and -6.5%±8.6%, and -0.1%±5.5%, respectively, in the control group. Post-operative change in ECD and pachymetry between two groups was not statistically significant (P>0.05).

Conclusions:

The femtosecond laser did not add to the endothelial damage caused by cataract surgery. In our study, statistically significant difference was not observed in results between two techniques during the observational period.
