Effect of phacoemulsification on intraocular pressure in eyes with pseudoexfoliation

A long-term reduction in mean IOP occurred in PFX eyes with and without glaucoma. The IOP reduction was proportional to the preoperative IOP; higher preoperative IOP was associated with a greater reduction in IOP. Glaucoma progression in both groups was low, suggesting a protective effect of phacoemulsification on IOP in these eyes.
