Abstract Details

Purpose:

To compare surgical outcomes (intraoperative and postoperative) between patients who underwent laser refractive cataract surgery with a femtosecond laser and those with conventional cataract surgery

Setting:

Sungmo Eye Hospital / LenSx(Alcon)

Methods:

In this retrospective study, 31 eyes from 31 patients underwent laser refractive cataract surgery (laser group; Alcon LenSx femtosecond laser), and conventional cataract surgery with phacoemulsification was performed in 30 eyes from 30 patients (conventional group). Main outcome measures included visual results, CCC circularity, IOP tilt, and CDE

Results:

Between the laser and conventional group, no statistically significant difference were noted in postoperative visual acuity, astigmatism, aberration, visual quality, and OP time (P>.05). CCC circularity values (size, decentration) were significantly better in the laser group (P<.05). The laser group had significantly lower values of IOL horizontal tilt (1.23 +/- 0.36 vs 2.56 +/- 0.54) and mean absolute error (0.29 +/- 0.12 vs 0.51 +/- 0.21). The overall mean cumulative dispersive energy was 9.76 +/- 10.53 for the laser group and 11.87 +/- 13.29 for the conventional group, a 17% reduction (P<.05).

Conclusions:

Laser refractive cataract surgery with a femtosecond laser resulted in a more precise capsulorrhexis, a more stable IOL positioning and a better predictability of IOL power calculation, decreased cumulative dispersive energy
