Abstract Details

Purpose:

To compare visual recovery and refractive changes after femtosecond laser-assisted cataract surgery (LCS) with standard cataract surgery.

Setting:

Ruhr University Eye Clinic, Bochum, Germany

Methods:

We present a prospective randomized intraindividual cohort study. 100 eyes of 100 patients were treated by laser-assisted cataract surgery and the fellow 100 eyes underwent phacoemulsification using pulsed ultrasound energy and intraocular lens implantation. The manifest refraction, spectacle-corrected distance visual acuity (CDVA), anterior chamber depth and capsular bag diameter were determined preoperative and at 2 hours, 3-4 days, 1 week, 1 month, 3 months, and 6 months postoperative visit to determine the achieved deviation from target refraction, intraocular lens position and refractive stability.

Results:

196 eyes at 6 months postoperatively were included and analyzed. The LCS group required less ultrasound energy to remove the softened nucleus than the standard group (EPT 0.02 vs. 1.27 sec, p<0.005). 71% and 100% were within ± 0.5 diopters (D) and ± 1.0 D, respectively, of their intended refractive outcome at 6-months post-operative in the standard group and 85% and 100% were within ± 0.5 D and ± 1.0 D of their intended refractive outcome at 6-months post-operative in the LCS group. Mean Refractive Spherical Equivalent (MRSE) showed no significant change after the 1-month postoperative visit in the standard group and after the 1-week postoperative visit in the LCS group. The LCS group had statistically significant less capsular bag shrinkage than the standard group at every time point from 1 week to 3 months (p<0.05) and high significantly less shrinkage between time periods 1 and 3 months (p<0.005).

Conclusions:

The femtosecond laser-assisted cataract surgery showed faster visual recovery as well as an earlier stable positioning of the IOL and less capsular bag shrinkage.
