Abstract Details

Purpose:

Evaluate the effectiveness of cataract extraction with femto-assisted FLAC and evaluate the presence of significant difference in endothelial loss following an ultrasound-free removal.

Setting:

Fondazione Poliambulanza, Brescia Italy

Methods:

one surgeon operated 40 patients by cataract extraction. All patients were operated by FLAC femto-assisted technique, performing the capsulorhexis with femtosecond laser, the constant patterning at eight passages on longitudinal and meridian axes, performing clear cornea incisions with laser Catalys. The surgeon operated all patients with stop technique and femtolaser-modified double linear with Signature instrument. In the series were included 20 patients in which the surgeon completed the surgery with parameter EFX (Ellipse FX Technology actual time phacoemulsification) equal to zero. The control group included 20 serial patients in which the surgeon used a variable number of ultasounds (Efx> 0).

Results:

The sample underwent pre-operative and 15-day endothelial reflection counting to measure the perioperative  cell loss. FLAC assisted femtolaser technique for cataract extraction allows a better conservation of the corneal endothelium. The femtolaser cataract surgery technique can allow the cataract to be extracted without any ultrasound emission. This parameter is obtained by double linear surgery and with EFX at the end of the intervention equal to zero. The surgeon who performed the surgical series in analysis was able to complete the surgery with EfX = 0 in 40.9% of cases. In the whole series considered the efx was equal to 1.55.

Conclusions:

The use of efx at zero resulted in an average endothelial loss of 93 CD cells / mm2 at fifteen days after the operation. The mean loss of the control sample operated with efx (average value 2.72) was 225 cells of average CD / mm2 reduction. The reflection method has repeatability limits in the area of analysis of mean endothelial cellularity.
