July 2, 2015

SEATTLE – Refracting patients with a device that uses point spread function instead of Snellen letters provides more sensitive results without the need for binocular balancing, a clinician said here at Optometry’s Meeting.

David I. Geffen, OD, FAAO, performed a study in the right eyes of 30 patients who presented for a routine exam in his practice. He presented his results in a poster here at the meeting and also in a “live poster session.”
