Abstract Details

Purpose:

Objective From the perspective of the author stages of development of laser-based cataract surgery ( 'LASICAT' Rasch, 2004) are shown. In particular, the possibilities of personalized femto cataract surgery are demonstrated by Lensar-Streamline II and evaluated the first 100 astigmatic (A.I.).

Setting:

The personalization and automation with Lensar-Streamline II opened a 2nd generation Femto-cataract surgery: 'LASICAT II'.

Methods:

Based on over 650 treatments with the Lensar system (more than 100 personalized with Streamline) individualized nuclear fragmentation, Cassini assisted astigmatism and the axle marks for toric IOLs are shown on case studies. The A.I. Cuts were made in 102 eyes during cataract surgery and first in 7 pseudophakic eyes with astigmatism to 4.5 Dpt. In the follow-up and subjective refraction and the astigmatic change(Pentacam) stand in the foreground.

Results:

The core hardness adapted fractionation reduces the applied energy with softer cores compared to the standard method in harder facilitates higher energy, the 'rest-Phaco'. The Streamline based Arcuaten incisions (A.I.) show after 3 months a significant reduction of astigmatism. For a final assessment, the long-term controls are to be seen. The axle marks with laser in corneal stroma for the implantation of toric IOL is easily visible and facilitates the positioning of the IOL.

Conclusions:

The custom cataract surgery by LensAR Streamline and Cassini topography allowed 1. Measurement of the core hardness and automated, individual adjustment of the laser energy for fragmentation. This is gentler with softer cores and with hard cores more effectve. 2. Pre-selection of Rhexis-diameter with precise execution. 3.The automated iris recognition by AI sections allow exact placement of incisions and reduction of astigmatism. The meaningful indications as regards the level of astigmatism are yet to determine on long-term controls. 4. The automated intrastromal corneal axle marks for positioning of toric IOLs are safer.
