Abstract Details

Purpose:

The purpose of this study is to analyze the phacoemulsification parameters and outcomes in femtosecond laser assisted cataract surgery (FL), compared with conventional Divide and Conquer (DQ) phacoemulsification cataract surgery

Setting:

University Hospital/Prospective Control Trial

Methods:

Seventeen eyes with FL and 28 eyes with conventional DQ were included. All the cataract surgeries were performed by a single surgeon with torsional phacoemulsification (Infinity, Alcon). In FL group, CCC and nucleus softening with 6 radial cut and cube formation were done with femtosecond laser (Catalysis, AMO). Phacoemulsification parameters such as total phaco-time, cumulative dissipated energy (CDE), infusion fluid used, and phaco-energy were measured in two groups. Pre-op and immediate post-op corneal thickness (CT) were also measured.

Results:

Age of patients and nucleus density were similar in both groups. Most of them had LOC III nucleus density. Volume of infusion fluid was decreased significantly in FL group compared with DQ group (56.1±9.4 vs 66.7±11.2 ml, p<0.05). Less CDE was used in FL group compared with DQ group (5.16±2.6 vs 6.91±3.7 power x s, p=0.14). There were no difference in total phaco-time, average phaco power, and changes of central CT. Cataract with dense nucleus (LOC >V) seemed to need less phaco energy in FL group, however, the sample size was too small to draw the conclusion.

Conclusions:

Femtosecond laser cataract surgery may be beneficial in decreasing volume of infusion fluid and phaco energy. Especially, in hard nucleus surgery, phaco energy can be decreased more. However, further study with a large sample will be needed.
