EVALUATION of CATS TONOMETER PRISM in LASIK SUBJECTS

An observational study in Glaucoma, Ocular Hypertension and Normal Tension Glaucoma, sponsored by Intuor Technologies, Inc.. Completed at 2 sites in United States. Open to participants aged 22 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-11-05.

Low Tension Glaucoma
Why
  1. The study's listed conditions name Low Tension Glaucoma, a narrower term within Glaucoma.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The CATS Tonometer prism clinical study is intended to determine repeatability of intraocular pressure measurement in human corneas which have undergone a LASIK procedure when compared to a standard Goldmann prism, validating the human LASIK eye findings comparing CATS Tonometer and Goldmann prisms to intracameral pressure in cadaver eyes.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
