Cataract surgery using the Femto Laser technology aims to be the next step in surgery concerning safety, predictability and efficacy. The LensAR Laser System integrates proprietary automated biometry, advanced ocular imaging and measurement technology, 3D-CSI (Confocal Structured Illumination) with an advanced ultra-short pulse laser. This technique enables the system to perform corneal incisions, limbal relaxing incisions, capsulorhexis and lens fragmentation. The authors report on the first results with the new Lensar Femto laser compared to standard cataract surgery with standard 2.4mm clear cornea incision and manuel capsulorhexis.
To report about the first 110 eyes treated with the LensAr Femto Laser at the eye hospital Bellevue in Kiel/Germany in the early learning curve.
In a prospective clinical trial the results of the first 110 cataract eyes treated with the LensAr Femto laser concerning the intraoperative performance are reported. Femto Laser treatment was performed by one surgeon. Phacoemulsification was performed by two surgeons with the same phaco system (Oertli, Switzerland).
In all eyes no intraoperative complications induced by the laser occurred. Suction time for diagnostic imaging, rhexis and nucleus fragmentation has decreased (after learning curve effect) to around 2,5 minutes. The rhexis was complete, round and centered to the pupil as planed in all cases. Nucleus fragmentation was completed regarding the different planned pattern. Total phaco time was on average 1,56 seconds (standard phaco on average 4,88 seconds). Mean endothelium cell loss was 6,84% (standard phaco on average 11,83%).
The early results are promising regarding the safety and efficacy of the new Femto Laser technique in the first 110 eyes treated using the LensAr platform. No medical intraoperative complications, which may be traced back to LensAR laser system, have appeared. Furthermore, less endothelium cell loss and less use of ultrasound energy have been determined compared to standard phaco.
