Abstract Details

Purpose:

To assess the reduction of preoperative astigmatism with intrastromal, non-penetrating arcuate incisions created by a Femtosecond Laser in patients undergoing cataract surgery

Setting:

1-Athens Metropolitan Hospital, 2-Ophthalmo-Check Eye Center. 3- Hypervision Eye Center

Methods:

This prospective study comprised 20 eyes of 20 patients with preoperative astigmatism of 0.5-1,50 D scheduled to undergo cataract surgery using a femtosecond laser platform to perform capsulotomies, lens fragmentation and arcuate keratotomies. The Verion Image Guided System nomogram was used with modifications in the arc size for the calculation of the keratotomies. An optical zone of 8.0 mm was used. Vector analysis was utilized for the calculations of astigmatic changes. One-year results will be presented.

Results:

The reduction of astigmatism was 0,13 D at 1 year. This result is statistically non-significant (P>0,10). The stabilization of astigmatism was observed after the first month.

Conclusions:

The effect of intrastromal arcuate keratotomies in tthe eyes of this study was insignificant at one year. Further studies with improvement of nomograms  (variations of optical zone size, incision arc length and laser spot energy) are required in order to assess the efficacy of the intrastromal arcuate incisions made by femtosecond laser in eyes with low preoperative astigmatism.
