Elevated Intraocular Pressure (IOP) in Primary Eyes ≥ 30 mmHg Primary · 1-6 hours postoperatively

The number of primary (first implanted) eyes that have elevated intraocular pressure measuring ≥ 30 mmHg as assessed with applanation tonometry which is a noninvasive test that measures the pressure inside the eye by flattening a part of the cornea.
