Intraocular Pressure Changes After Corneal Laser Refractive Surgery
Summary
This ClinicalTrials.gov registry entry describes a prospective observational study (NCT07549815) evaluating changes in intraocular pressure following corneal refractive surgery procedures including PRK, LASIK, and femtosecond laser surgery using Corvis CT results and applanation tonometry measurements. The study will assess multiple surgical techniques to determine their effects on intraocular pressure readings. No compliance obligations, deadlines, or enforcement actions are associated with this study registration.

About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
This document registers a clinical study on ClinicalTrials.gov describing the protocol for measuring intraocular pressure changes following corneal laser refractive surgery. The study evaluates PRK, LASIK, and femtosecond laser procedures using Corvis CT machine measurements and applanation tonometry. Clinical sites preparing to conduct refractive surgery research may reference this registry for methodology considerations. The document imposes no obligations on regulated entities and does not modify any existing regulatory framework.
Affected parties include ophthalmic surgeons, clinical investigators, and eye care facilities involved in refractive surgery or intraocular pressure research. The registry entry provides standardized study parameters but does not create compliance requirements. Investigators should note the study's focus on measurement technique comparison when designing related clinical protocols.
