Abstract Details

Purpose:

To demonstrate the changes in intraocular pressure (IOP) during the femtosecond laser procedure

Setting:

Department of Ophthalmology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea

Methods:

Medical records of 53 eyes of 47 patients who underwent the femtosecond laser procedure were reviewed. We evaluated the nuclear sclerosis grades and laser powers for each patient. We measured the IOP before laser procedure, immediately after laser procedure, 30 minutes after laser procedure, and 1 hour after laser procedure.

Results:

The mean IOP was 17.15±3.45 mmHg before laser procedure, 29.81±7.14 mmHg immediately after laser procedure, 17.70±3.88 at 30 minutes after laser procedure, and 21.51±5.84 at 1 hour after laser procedure. There was a significant increase in the mean IOP both immediately and 1 hour after laser procedure compared with pre-laser procedure IOP (P<0.001). The mean IOP at 30 minutes after laser procedure was significantly lower than that immediately after laser procedure (P<0.001). There was a significant increase in the mean IOP 1 hour after laser procedure compared with the IOP 30 minutes after laser procedure (P<0.001).

Conclusions:

We demonstrated that there is an IOP elevation after the femtosecond laser procedure and an elevated IOP decrease as time passes, however, the IOP increases again 1 hour after laser procedure. Therefore, the timing of the beginning of cataract surgery after the femtosecond laser should be considered.
