Abstract

Purpose

To evaluate the safety of phacoemulsification cataract surgery in the patients undergoing dual antiplatelet therapy with aspirin and clopidogrel.

Methods

Consecutive patients undergoing phacoemulsification cataract surgery with a clear corneal incision under topical anesthesia were eligible for inclusion in the study. Thirty-eight eyes from 38 patients on combined aspirin and clopidogrel therapy who continued the treatment were classified into the maintenance group, a matched group of 38 eyes from 38 patients on no antiplatelet/anticoagulant therapy as the control group. The best-corrected visual acuity (BCVA) and incidences of complications were compared between the two groups.

Results

There was no significant difference in final BCVA between the maintenance group and the control group (p = 0.178). No significant difference existed in the incidences of hemorrhagic or non-hemorrhagic complications between the two groups (p = 0.529 and p = 0.589, respectively). Moreover, no surgery was postponed or cancelled due to hemorrhagic complications in either group, and no cardiovascular events occurred during the follow-up. There was no case of anterior chamber hemorrhage, vitreous hemorrhage, or suprachoroidal hemorrhage.

Conclusions

Our outcomes indicated that phacoemulsification cataract surgery using a clear corneal incision with topical anesthesia could be safely done without stopping dual antiplatelet therapy with aspirin and clopidogrel.
