Effect of artificial tears on eye measurements
Part of Eyes & vision clinical trials.
This study tests whether putting artificial tears (a type of lubricating eye drop) in your eyes changes measurements of your eye's shape and size. The results could help doctors get more accurate readings before planning cataract or other eye surgeries.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You can sit still and look at a light during an eye exam.
- Your eyes are not cloudy (no cataracts, scars, or bleeding inside the eye).
- You have not used any eye drops in the past 24 hours and do not have severe dry eye.
- You have not had eye surgery, an eye injury, or an allergy to sodium hyaluronate (a common ingredient in artificial tears).

This study looks at how dry eye symptoms change after cataract surgery. It is for older adults (50–90) having simple cataract surgery for the first time, without other eye problems or certain health conditions.
This trial tests a new eye drop called PRO-240 versus Optive artificial tears in healthy adults. You will attend several visits over a few weeks and use the assigned drops as directed. The goal is to see if the new drop is as safe and comfortable as the standard one.
This trial tests a new eye drop gel (CsA-PG) for people with dry eye disease. Participants must have had dry eyes for at least 6 months and meet specific eye exam scores. The study checks if the gel can improve symptoms and eye health.
This study checks whether treating dry eyes before cataract surgery can change the way your eye's shape (astigmatism) is measured. It may help make your surgery more accurate.
This study compares two different eye drop lubricants to see which one works better for people with dry eye symptoms. You would use only the study drops for the whole time and attend a few visits to check your eyes.
This trial tests whether closing the eyelids changes the accuracy of a cornea measurement tool. It may help people whose cornea measurements are flagged as "warning" by the device.
