Purpose
To evaluate the changes of intraocular pressure (IOP) following femtosecond laser-assisted cataract surgery (FLACS)
Methods
We retrospectively reviewed the medical records of 53 eyes of 47 patients who underwent the FLACS procedure. We examined the nuclear sclerosis grades and noted the femtosecond laser powers for each patient. We measured the IOPs before the femtosecond laser procedure, and then immediately, 30 minutes and 1 hour after the laser procedure.
Results
The mean nuclear sclerosis grade was 3.70±0.95, and the mean laser power was 8.45±1.75J. The mean IOP was 17.15±3.45mmHg before the laser procedure, 29.81±7.14 immediately after the procedure, 17.70±3.88 at 30 minutes after the procedure, and 21.51±5.84 at 1hour after the procedure. There was a significant increase in the mean IOP both immediately and 1 hour after the procedure compared with the pre-laser procedure IOP(p<0.001).But, there was no difference between the IOP 30 minutes after the laser and the IOP with the pre-laser procedure (p=0.247). There was a significant increase in the mean IOP 1 hour after the laser procedure compared with the IOP 30 minutes after the procedure(p<0.001).
Conclusion
IOP changes presented dynamically following the femtosecond laser procedure and was magnified 1 hour after the laser procedure, suggesting that beginning time of cataract surgery after laser procedure should be cautiously selected.
