Higher Order Aberration and Relationship With Soft Contact Lens Modulus

Not yet recruiting
Conditions
Corneal Wavefront Aberration
Registration Number
NCT06425432
Lead Sponsor
Southern College of Optometry
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Mean change in HOA with and without contact lensesWithin the same study visit, measurements will be taken 15 minutes apart to allow for tear film to return to homeostasis after contact lens insertion/removal.

Measure HOA with contact lenses. And then measure HOA without contact lenses.

Secondary Outcome Measures
NameTimeMethod
Correlation between contact lens modulus and changes in HOA with and without contact lensesWithin the same study visit, measurements will be taken 15 minutes apart to allow for tear film to return to homeostasis after contact lens insertion/removal.

Evaluate correlation between the lens modulus and changes in HOA
