NCT07518316
Factors Influencing Subjective Visual Quality in Human Eyes
To assess subjective visual symptoms using the QoV questionnaire, measure pupil size using the Atongmu Pupillometer, measure wavefront aberrations using the OPD-Scan III Aberrometer, and measure/calculate the effective optical zone using the Pentacam system. The relationships between pupil size, higher-order aberrations (HOAs), effective optical zone after refractive surgery, and subjective visual symptoms will be explored.

Higher Order Aberration and Relationship With Soft Contact Lens Modulus
Higher order aberrations are imperfects in the eye that affect the quality of image projected onto the retina. Soft contact lenses are made of different materials with different stiffness. This study looks to see if the soft contact lens material affects the amount of higher order aberrations in an eye.
