Pre-Excimer Laser and Post-Excimer Laser Refractive Surgery Measurements of Scotopic Pupil Diameter Using 2 Pupillometers

The digital infrared pupillometer showed better preoperative and postoperative repeatability than the handheld light amplification pupillometer. In the present study, a mean correction of <3 D of the corneal refractive power did not seem to modify the preoperative scotopic pupil size measurements.
