Perceived Pain during Cataract Surgery with Topical Anesthesia: A Comparison between First-Eye and Second-Eye Surgery

Figure 1

Comparison of blood pressure and heart rate among cataract patients who underwent first-eye or second-eye surgery. SP, systolic pressure; DP, diastolic pressure; MAP, mean arterial pressure; HR, heart rate. Systolic blood pressure, diastolic blood pressure, and mean arterial pressure were significantly different between the postoperative and intraoperative measurements (all ; one-way analysis of variance, followed by the least significant difference test).
