简要总结

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.

结局指标

主要结局

Mean change in HOA with and without contact lenses

时间窗: Within 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.

次要结局

Correlation between contact lens modulus and changes in HOA with and without contact lenses(Within 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.)
