Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Some of the postoperative complaints of patients having refractive corneal or lens surgery are related to visual quality and are associated with large pupils since optical aberrations become more dominant when the pupil dilates . If the pupil size exceeds the optical zone size, a marked increase in higher-order aberrations could be observed. Patients might complain about poor contrast sensitivity, increased glare disability, or halos. Precise measurement of scotopic pupil diameter has therefore become an essential step in the preoperative evaluation of patients suitable for refractive surgery and is an important inclusion or exclusion criterion.
This study aimed to assess the agreement and reproducibility of scotopic pupil size measurements using 2WIN-S compared with OPD-Scan III in Chinese adults.
