Summary

With the development of refractive surgery, the size of scotopic pupil has been widely concerned by clinicians. Historically, the measurement of pupil size included the use of a pupil ruler, which is known for its drawback of being very subjective and lacking precision. While infrared pupillometry devices such as OPD-Scan III and Sirius are available for accurately and reliably measuring pupil size. Nevertheless, the aforementioned equipments are costly and cumbersome to move in terms of screening and field trial logistics settings. And 2WIN-S is a portable refractor, it can in a short period of diopter and scotopic pupil size and other data obtained at the same time. Therefore, the aim of this study was to compare the agreement between 2WIN-S and OPD-Scan III in measuring scotopic pupil size and the repeatability of 2WIN-S.
