Abstract Details

Purpose:

To compare the outcomes of femtosecond laser–assisted cataract surgery(FLACS) and conventional phacoemulsification followed by multifocal intraocular lens (IOL) implantation.

Setting:

Asan Medical Center, Seoul, South Korea

Methods:

Depending on their preference, patients had FLACS or conventional phacoemulsification. Patients in the femtosecond group with corneal astigmatism greater than 0.75 diopter also had arcuate keratotomy. All eyes had multifocal IOL implantation. One month after treatment, the uncorrected distance and near visual acuities, spherical equivalent, corneal and refractive astigmatism, aberrometry results, and questionnaire results were compared between two groups. Correlations between target-induced astigmatism (TIA) and surgically induced astigmatism (SIA) were also compared between the groups.

Results:

The femtosecond group comprised 17 patients (23 eyes), with arcuate keratotomy performed in 14 eyes. The conventional phacoemulsification group comprised 22 patients (26 eyes). In the femtosecond group, the difference in corneal astigmatism between preoperatively and postoperatively was statistically significant. The correlation between TIA and SIA was greater in the femtosecond group. Corneal root-mean-square higher-order aberrations (RMS HOAs) (P< .01) and total trefoil (P= .043) were significantly higher in that group. However, internal total RMS (P= .05), tilt (P= .041), and RMS HOAs(P= .047) were significantly lower in the femtosecond group. Satisfaction scores were significantly higher in that group.

Conclusions:

Change of astigmatism was more predictable in the FLACS group. Internal aberrations, including total RMS, tilt, and RMS HOAs, were lower in the femtosecond group than conventional phacoemulsification group , also patients in the femtosecond group were more satisfied.
