Natural Course of Intraocular Pressure after Cataract Surgery with Sodium Chondroitin Sulfate 4%-Sodium Hyaluronate 3% (Viscoat)

Significant IOP increases were found during the first 24 hours, peaking at 1 hour after surgery. With a single postoperative IOP measurement, between 30 minutes and 2 hours after surgery, two thirds of these IOP spikes could be detected. To detect all IOP spikes, a second measurement between 4 and 6 hours after surgery would be necessary.
