Abstract

The perioperative management of the pupil is essential to the success of anterior segment surgery. A new dilating regimen was tested in 65 cases of cataract extraction and intraocular lens implantation. The α-adrenergic agonist, phenylephrine 2.5%, was used after pretreatment with the adrenergic β-blocker, timolol 0.5%. This treatment successfully dilated the pupil in all but three cases, was maintained by intraoperative epinephrine infusion, and was readily reversed with intraocular acetylcholine. We conclude that this pharmacologic regimen provided a successful and easily reversible mydriasis during surgery.
