Abstract Details

Purpose:

The purpose of this work is to compare two femtosecond laser platforms (Victus and Ziemer LDV8) and to evaluate the advantages of femtolaser energy in combine with laser cataract extraction using Nd:YAG laser �Î�»=1.44�Â�µm .

Setting:

The S. Fyodorov Eye Microsurgery Federal State Institution. St. Petersburg Branch , St. Petersburg, Russia.

Methods:

All patients were divided in two groups. Each group were included 20 eyes. In first group patients underwent cataract surgery by FLACS using the Victus (Germany) platform and in second using Ziemer LDV8 (Switzerland) platform. We made femtosecond laser assisted corneal incisions of 65 degrees 2.0mm, anterior capsulorhexis (4.5-5.5 mm) and lens fragmentation (6 radial segments). The lens fragmentation energy depends on nuclear density and varied from 7800 to 8500 nJ (frequency �â�€�“ 160 kHz) in the first group, 100-120% (frequency �â�€�“ 5MHz) in the second. The complete lens fragmentation and nuclear removal was performed with 1.44�Â�µm Nd:YAG laser phacomachine.

Results:

Interface, docking, profile of clear corneal incision and lens fragmentation were scored 0-5 in all cases. All eyes were examined postoperatively at day-1, day-7. Corneal endothelial microscopy (endothelial cell density (ECD) and best corrected visual acuity (BCVA) were evaluated. Good functional results were obtained in both groups. There were no complications neither in the femto procedure nor during cataract surgery in all cases. Features and advantages of the both femtosecond laser platforms are discussed.

Conclusions:

Despite differences in two femtosecond laser platforms, both provide simplification of cataract surgery.
