Abstract Details

Purpose:

To study intraocular pressure (IOP) during Femtosecond laser-assisted cataract surgery (FLACS).

Setting:

University Eye Clinic of Trieste, Italy.

Methods:

116 eyes of 108 patients underwent FLACS: 61 eyes using Catalys® Precision Laser System with Liquid Optics Interface (group 1), 55 eyes using LenSx® Precision Laser System with soft lens assisted interface (SoftFitTM)(group 2). IOP values were measured with a portable rebound tonometer (Icare®) preoperatively, after laser application, immediately after surgery, two hours later, the day after and after seven days.

Results:

In group 1, the mean IOP (± SD) before surgery was 15.56 ± 3.88 mmHg. After docking 35.75 ± 9.15 mmHg, after surgery 22.64 ± 7.79 mmHg, after two hours 14.49 ± 3.36 mmHg. In group 2, the mean IOP before surgery was 13.80 ± 2.24 mmHg. After docking 25.53 mmHg ± 10.16, after surgery 20.44 ± 8.27 mmHg, after two hours 13.21 ± 3.09 mmHg. In both groups, the IOP measured the day after and 7 days after was not significantly greater than the preoperative values. There were no intraoperative complications.

Conclusions:

Femtolaser-assisted cataract surgery lead to an increase of the IOP during suction phase, higher in patients of group 1. The use of a large amount of energy for nuclear fragmentation could correspond in a net increase of intraocular pressure.
