Abstract Details

Purpose:

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 after 30 eyes treated with paired LRI with the LENSAR Femto Laser.

Setting:

To report about the first clinical results for the developing of an own normogram after 30 eyes treated for cataract and astigmatism with the LENSAR Femto Laser at the eye hospital Bellevue in Kiel/Germany.

Methods:

Femto Laser treatment for LRI, capsolotomy and lens fragmentation and phacoemulsification with the same phaco system (Oertli, Switzerland) was performed by one surgeon. Phacoemulsification. Limbal incision of 2.4mm was used in all patients. The follow up is up to one 6 months. Pre- and postoperativly corneal astigmatism was measured by objective refraction, Zeiss IOL Master, Keraton scout and Schwind Sirius camera. Irregular corneal astigmatism or any other corneal pathologies were exclusion criteria.

Results:

In all eyes no intraoperative complications induced by the laser occurred especially no perforation of the cornea due to the lRI. Suction time for diagnostic imaging, rhexis and nucleus fragmentation and LRI was around 3,0 minutes. The amount of corneal astigmatism was significantly reduced in all measurements with the different devices. In average the reduction was up to 60% of corneal astigmatism. Mean corneal astigmatism changed from 2.1dpt to 1,0dpt. No over correction occurred.

Conclusions:

The results are promising regarding the safety and efficacy of the LRI procedure using the LENSAR platform. Longer follow up and adaption of the normogram for further reduction of astigmatism is nessecary. The possibility of treating the corneal astigmatism in the same operation in a standardized way is another advantage FLACS compared to thetraditional phaco technique.
