How eye prescription affects corneal thickness measurement
Part of Eyes & vision clinical trials.
This study measures the thickness of the clear front part of your eye (cornea) using two different scanners (Pentacam and IOL Master). It helps doctors plan safer surgery for people with common vision problems like nearsightedness, farsightedness, or astigmatism.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 20 and 41 years old.
- You are planning to have refractive eye surgery (like LASIK or PRK).
- You have no scars or clouding on the front of the eye (the cornea).
- You do not have corneal diseases like keratoconus or dystrophies.
- You have not had any previous eye surgery, injury, or inflammation (uveitis).
- You have not worn contact lenses recently.

This study measures how light passes through the clear front part of your eye (cornea) using a specialized camera. These measurements help doctors better understand eye health and may improve future eye care.
This study uses a special eye imaging technique to map the thickness of the clear front layer of your eye (cornea) in people with nearsightedness or farsightedness. The goal is to better understand how corneal thickness relates to refractive errors and help improve eye care.
This trial is studying people with thick corneas (over 540 microns) and high back elevation to understand this condition better. It aims to find out if there are any risks or health issues related to these eye measurements.
This study measures corneal thickness after cataract surgery in people with and without Fuchs' endothelial dystrophy (a condition that can cause cloudy vision). It may help doctors understand how the cornea heals after surgery.
This study looks at how clear and thick the cornea (the clear front part of the eye) is in people with cataracts. It may help doctors understand more about eye health during cataract treatment.
This study measures the front part of the eye (anterior chamber depth) in people with high myopia (severe nearsightedness). It uses two types of eye scans (OCT and Pentacam) to see how these measurements compare.
