Abstract Details

Purpose:

Femtosecond laser has been successfully used to perform capsulorhexis and lens fragmenations. Prior studies have compared the visual and refractive outcomes of SIA and HOA comparing manual versus femtosecond CCI of 2.75-2.8 mm width. This study evaluated the effect of 2.0-2.2 mm wide manual versus femtosecond laser CCIs on SIA and HOA.

Setting:

IRB monitored study.Surgery performed at an approved ambulatory surgery center in Lindenhurst, IL;:office measurements performed preoperatively and postoperatively at Jacksoneye in Lake Villa IL.

Methods:

In this prospective, randomized, controlled clinical trial, study group included 20 eyes of 20 patients who underwent FLACS with a 2.2 mm biplanar CCI and control group included 20 eyes of 20 patients who underwent conventional phacoemulsification with a 2.0 mm biplanar CCI with a disposable keratome with attempted wound architecture similar to study group. Inclusion criteria included visual impairment from cataract, preop sphere less than -8.00 D and preop cylinder less than 2.0 D. Preoperative and postoperative corneal topography and wavefront aberrometry were obtained using Marco/Nidek OPDIII scan.

Results:

Both the study (FLACS) and control (conventional phacoemulsification) groups were statistically comparable with regard to SIA. Induced higher order aberrations (HOA) were statistically lower in the study group.

Conclusions:

Manual and femtosecond laser assisted clear corneal incisions (CCI) of width 2.0-2.2 mm were shown to have comparable effect on visual and refractive outcomes. The lower induction of higher order aberrations in the FLACS study group may correlate to clinical advantages in this group of patients.
