About

The goal of this clinical trial is to learn about the influence of artificial tears on measurements of healthy eyes with three different devices. The main questions it aims to answer are:

• Do artificial tears alter the measurements of the corneal surface
• Is there a difference between the devices used in this study

This is relevant because high quality measurements improve the postoperative outcome after cataract surgery.

Enrollment: 145 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Healthy eyes

Exclusion criteria

• Any prior intraocular surgery or trauma

• Active ocular pathology (e.g., amblyopia, ARMD)
• Contact lens wear within 2 weeks of study
• Any corneal relaxing incisions or astigmatic keratotomy
