Details and patient eligibility

About

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.

Enrollment: 100 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Trial design

100 participants in 2 patient groups

CL first

Description:

Subject will present wearing habitual contact lenses for the aberrometry measurement. They will then remove their contact lenses and measurement repeated uncorrected.

Treatment:

Device: OVITZ xwave aberrometer

Glasses first

Description:

Subjects will refrain from contact lens wear on day of the visit. Initial aberrometry measurement will be performed uncorrected. They will be then asked to insert their contact lenses and aberrometry measurements repeated.
