PURPOSE: To evaluate the mydriatic effect of topical cyclopentolate 1% when combined with topical phenylephrine 10% and intracameral lidocaine 1% in phacoemulsification cataract surgery.
METHODS: We performed a prospective, double-masked, randomized trial including 20 patients with age-related cataract, who were scheduled for unilateral phacoemulsification and intraocular lens (IOL) implantation. Patients were given either two drops of phenylephrine 10% at 30 mins and 15 mins prior to surgery (group 1), or two drops each of cyclopentolate 1% and phenylephrine 10% at the same time points (group 2). All patients were also given lidocaine 1% intracamerally at the beginning of the procedure. Intraoperative pupil sizes were assessed from video-recordings.
RESULTS: Initially, pupil sizes were significantly smaller in group 1 (4.8 +/- 1.2 mm versus 6.5 +/- 1.4 mm; p = 0.0098), but the lidocaine injection increased the pupil sizes in group 1 significantly, so that pupil sizes in both groups were equalized throughout the surgical procedure.
CONCLUSIONS: Preoperative topical cyclopentolate does not enhance mydriasis in phacoemulsification surgery when using intracameral lidocaine and can be omitted when intracameral lidocaine is used.
