Summary

The CA-800 Corneal Analyzer (Visia Imaging S.R.L., Italy) is a device that can measure small imperfections in the tear film when the eyes are open. The goal of this study is to see if the device can detect changes in the tear film after instillation of an eye drop or when contact lenses are worn.

Conditions

  • Tear Film Characteristics

Interventions

DRUG

Systane Complete Preservative-Free

One drop of Systane Complete Preservative Free will be instilled in each eye. Higher order aberrations assessed before and after instillation.

DEVICE

Senofilcon A

Daily disposable silicone hydrogel contact lenses indicated for myopia or hyperopia. Higher order aberrations assessed before and after instillation.

DEVICE

Somofilcon A

Daily disposable silicone hydrogel contact lenses indicated for myopia or hyperopia. Higher order aberrations assessed before and after instillation.
