For patients on warfarin, continuing anticoagulation during cataract surgery is safe. Warfarinization did not increase risks, and stopping it could lead to dangerous blood clots.

Area of Science:

Ophthalmology
Cardiology
Pharmacology

Background:

Cataract extraction in patients taking warfarin requires careful consideration due to bleeding risks.
Discontinuing warfarin can increase the risk of serious thromboembolic events.

Purpose of the Study:

To evaluate the impact of warfarinization on cataract extraction outcomes.
To assess the safety and efficacy of performing cataract surgery on patients using warfarin.

Main Methods:

A retrospective review of 1000 consecutive cataract extractions performed between 1996 and 1998.
Analysis of 23 eyes from patients (29 total) who were on warfarin during the study period.

Main Results:

The mean preoperative international normalized ratio (INR) was 1.52 (range 1.00-2.40).

No thromboembolic events were observed in the warfarinized patients.

Four minor perioperative hemorrhages occurred, none impacting the final visual outcome.

Conclusions:

Warfarin should not be ceased perioperatively in patients requiring anticoagulation for thromboembolic risk.
Minor perioperative hemorrhages in warfarinized patients undergoing cataract surgery are not visually significant.
