New scanner could help surgeons predict cataract hardness
NCT ID NCT07425626
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a special scanning device that measures how stiff the eye's lens is in people with cataracts. Researchers want to see if this stiffness measurement matches standard cataract grading and surgery energy needed. 50 adults with cataracts will be scanned before surgery. This is a pilot study to gather data, not to test a treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help surgeons better plan cataract surgery by predicting lens hardness, potentially improving outcomes.
- What could go wrong
- This is a small pilot study focused on measurement, not treatment. The device may not prove reliable or useful in practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Men and women aged above 21 years 2. Normal ophthalmic findings except previous surgery or conditions that impact corneal optical quality such as trauma and corneal scars 3. Willing to sign informed consent before measurements 4. Presence of nuclear cataract according to LOCS III grading and planned cataract surgery Exclusion Criteria: Any of the following will exclude a subject from the study: * Patients with inadequate corneal imaging or corneal scarring that would impact results * Patients with active ocular infections or inflammatory conditions * Patients that suffered an eye trauma according to their medical history * Patients with fixational problems (e.g., nystagmus) or with any medical condition that could interfere with the measurements * Pregnancy (pregnancy test will be performed in women of reproductive age)
