The effects of functionally monocular patients' emotional reactions during phacoemulsification under topical anesthesia.

PURPOSE

To evaluate the relationship between the incidence of complications and functionally monocular patients' emotional reactions during phacoemulsification under topical anesthesia.

METHODS

We enrolled 22 functionally monocular patients (11 males and 11 females; group 1) and 19 age- and sex-matched controls (6 males and 13 females; group 2) in this prospective, interventional, cross-sectional, case control study. Demographics data, including age, sex, and educational background, were collected. Surgeries were performed by the same surgeon, and during surgery, the patients' vital signs (blood pressure and heart rate) and surgical events (duration, body movements, signs of increased vitreous cavity pressure, difficulty in performing capsulorhexis, and complications) were noted. Pre- and postoperative visual acuity was also analyzed.

RESULTS

The mean age of group 1 was 73.05 ± 13.31 years and of group 1 was 69.74 ± 16.81 years. There was no significant between-group difference in systolic and diastolic blood pressures. The average heart rate was similar in both groups, too. During surgery, the surgeon's perception of excessive eye, eyelid, or head movements in both groups was similar, in addition to signs of increased vitreous cavity pressure.

CONCLUSION

It is safe to perform phacoemulsification under topical anesthesia in functionally monocular patients, who apparently behave similarly to binocular patients.
