Abstract Details


LACS is increasingly used by cataract surgeons around the world because of the precision, efficacy and safety of the procedure. Another advantage of LACS prior standard phacoemulsification is the possibility to reduce preexisting corneal astigmatism in the same operation.. 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 in combination with the streamline software and the Cassini Total Corneal Astigmatism (TCA) topography.


nordBLICK Augenklinik Bellevue, Kiel, Germany


The study included 15 eyes with cataract and preexisting corneal astigmatism that underwent laser assisted cataract surgery combined with arcuate incisions (AI) for astigmatism correction. Preoperatively the Corneal astigmatism and iris picture were captured by the Cassini TCA topography. Surgeries were performed by a single experienced surgeon. Femtosecond laser assisted capsulotomy, lens fragmentation and AI were performed using the LENSAR femtosecond Laser Systemâ„¢. Phacoemulsification was performed using phaco system by Oertli followed with spherical IOLs implantation. Pre- and postoperative corneal astigmatism was measured by Cassini TCA, IOL Master, Keratron scout and Sirius. All patients were followed up to 6 months.


In all patients the preoperative data from Cassini TCA could be successfully imported via WLAN to the laser system. All system detected cyclotorsion was directly compensated intra-operatively. No laser associated intraoperative complications. No instance of perforation of the cornea due to AI. Suction time for diagnostic imaging, capsulorhexis, nucleus fragmentation and AI was around 3 minutes. The amount of corneal astigmatism was significantly reduced in all patients. On average, the reduction was around 60% (Mean corneal astigmatism changed from 1.32 D pre-operatively to 0,62 D post-operatively). No over correction occurred. Mean UDVA was 0,8 and mean CDVA was 1,0 post-operatively.


The results of the study demonstrate the safety and efficacy of the combined cataract and AI procedure using the Cassini TCA system and 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 LACS compared to the conventional phacoemulsification technique.
