Long-term effects of phacoemulsification with intraocular lens implantation in normotensive and ocular hypertensive eyes

Stratifying eyes according to presurgical IOP showed greater long-term IOP reductions than previously reported. The reduction was proportional to the presurgical IOP. The decrease was greatest in eyes with the highest presurgical IOP. The IOP remained unchanged in eyes with the lowest presurgical IOP. The IOP reductions at 1 year were sustained over 10 years and were similar in patients of all ages.
