Visual recovery after phacoemulsification using topical anesthesia

To assess the speed of visual function recovery after phacoemulsification using topical anesthesia.

Department of Ophthalmology, Royal United Hospital, Bath, United Kingdom.

Twenty consecutive patients having routine sutureless clear corneal phacoemulsification with implantation of a Staar foldable intraocular lens were recruited in a prospective study. Visual acuity was assessed using a LogMAR chart and contrast sensitivity using a Pelli-Robson chart 1, 2, 4, and 16 hours postoperatively. A final examination and refraction were performed at 1 week.

Although return of visual acuity was slow during the first 2 hours, the mean LogMAR acuity had improved to 0.425 (Snellen equivalent 6/15) by 4 hours and 0.165 (Snellen equivalent of 6/9.5) by 16 hours. There was no postoperative ptosis or diplopia.

The absence of diplopia and rapid return of visual function with a mean acuity of 6/15 by 4 hours suggest that early patient discharge is relatively safe.
