Routine cataract surgery leads to an immediate and persistent reduction in intraocular pressure (IOP) for patients with ocular hypertension, according to what may be the most pertinent study thus far to address the issue. Steven L. Mansberger, MD, from the Devers Eye Institute/Discoveries in Sight, Legacy Health System, Portland, Oregon, and colleagues found that IOP for patients with known ocular hypertension decreased a mean 16.5% after cataract extraction surgery; the difference between pre- and postoperative IOP (23.9 ± 3.2 mm Hg vs 19.8 ± 3.2 mm Hg) was significant (P < .001) and was still measurable 36 months after the procedure, although there was a trend toward increasing postoperative IOP over time of 0.05 mm/month (95% confidence interval, 0.02 - 0.07; P < .001).To see more details visit, www.medscape.com
