Effect of preoperative pupil measurements on glare, halos, and visual function after photoastigmatic refractive keratectomy

Abstract

An assessment of preoperative pupil size and the attempted level of both SE and astigmatic correction may be useful in identifying patients at risk of developing symptoms or declines in visual performance after PARK. However, follow-up studies are indicated to identify variables predictive of poor visual outcomes following excimer laser refractive surgery.
