Abstract Details

Purpose:

Surgeons across the world are increasingly adopting femtosecond technology, particularly due to its potential to improve the predictability, safety and efficacy of the surgery. The LENSAR femtosecond Laser System™ integrates automated biometry, advanced ocular imaging and measurement technologies, 3D-CSI™ (Confocal Structured Illumination) with an advanced ultra-short pulse laser, thereby enabling the system to perform capsulorhexis, lens fragmentation, clear corneal incisions for cataract surgery and arcuate incisions (AI). The present study aims to evaluate the outcomes of the femtosecond laser assisted combined cataract surgery and AI for the treatment of cataract with pre-existing astigmatism using LENSAR Femtosecond Laser after one year.

Setting:

nordBLICK Augenklinik Bellevue Kiel, Germany, prospective single surgeon study with ethic committee approval

Methods:

We evaluated a subgroup of our ongoing study including18 eyes of 13 patients with cataract and preexisting corneal astigmatism that underwent femtosecond laser assisted cataract surgery (FLACS) combined with arcuate incisions (AI) for astigmatism correction. (Mean age 68 years (±9 years)). Femtosecond laser assisted capsulotomy, lens fragmentation, and AI were performed using the LENSAR femtosecond Laser System™. Phacoemulsification was performed using phaco system by Oertli, Switzerland. Limbal 2.2mm incisions where performed. Pre- and postoperative corneal astigmatism was measured by Zeiss IOL Master, Keraton scout and Schwind Sirius camera. All patients were followed up for up to 12 months.

Results:

No intraoperative complications occurred, especially no perforation of the. Suction time for diagnostic imaging, capsulorhexis, nucleus fragmentation and AI was around 3 minutes. The amount of corneal astigmatism was significantly reduced in all the patients (Findings were same when measurements were performed with different devices). On average, the corneal astigmatism reduced by around 60%. Mean corneal astigmatism changed from 1,32 D pre-operatively to 1.61 D post-operatively. No over correction occurred. There was no significant change regarding the astigmatism from 3 to 6 to 12 months. Mean UDVA changed from 0.2 to 0.8. CDVA changed from 0.5 to 0.9.

Conclusions:

The results of the study demonstrate the safety and efficacy of the combined cataract and AI procedure using the LENSAR platform. Nomogram improvements are needed to allow further reduction of astigmatism. The possibility of treating the corneal astigmatism as well as cataract in the same operation in a standardized way is another advantage of FLACS compared to the conventional phacoemulsification technique.
