Abstract Details

Purpose:

To assess the outcomes of femtosecond laser assisted arcuate incisions (AIs) performed during cataract surgery utilizing iris registration guided cyclotorsion compensation.

Setting:

Jacksoneye, Lake Villa, IL

Methods:

This case series included 52 eyes of 31 cataract patients (mean age: 69 ± 11 years) with pre-existing astigmatism ranging between -0.4 to -2.75 diopters (D). All patients underwent LENSAR femtosecond laser assisted arcuate incisions during cataract surgery. Cyclotorsion was compensated by wirelessly transmitting the preoperative iris registration data from Cassini topographer to the LENSAR laser system and mapping it to the image of the eye obtained under the laser.

Results:

Refractive astigmatism reduced significantly from preoperative absolute mean of 1.3 D to 0.3 D postoperatively at least 6 months or greater (p value < 0.001). Correspondingly, double angle plots of preoperative and postoperative refractive astigmatism also demonstrated improvement after surgery. Preliminary outcomes of arcuate keratotomy procedure are good. More data are being collected and expanded results will be presented No intraoperative or postoperative complications were observed.

Conclusions:

LENSAR laser assisted astigmatism correction using arcuate incisions appear to be safe and effective in reducing pre-existing astigmatism during cataract surgery. Utilizing wireless transfer of iris registration data to compensate for cyclotorsion potentially helps improve the outcomes of arcuate keratotomy.
