Safety of tropicamide and phenylephrine in pupillary mydriasis for cataract surgery.

Purpose: A prospective study to evaluate the adverse cardiovascular effects of topical phenylephrine and tropicamide used for pupillary mydriasis before cataract surgery.

Methods: A total of 517 consecutive eyes in 517 patients subjected to routine 0.8% tropicamide and 5% phenylephrine eye drops before undergoing cataract surgery (phacoemulsification and manual small-incision surgery) under local or topical anesthesia in a medical college hospital were analyzed.

Results: No untoward cardiovascular effects were seen. The increase in blood pressure after 0.8% tropicamide and 5% phenylephrine eye drops was statistically significant, but it was not relevant as it was within clinically permissible limits.

Conclusion: The combination of 0.8% tropicamide and 5% phenylephrine eye drops is a safe and effective option for pupillary mydriasis before cataract surgery.
