Femtosecond Laser Assisted Keratotomies for the Management of Corneal Astigmatism
NCT04676451 · View on ClinicalTrials.gov ↗
Study Summary
A cataract is a clouding of the lens that occurs naturally with age. Cataract surgery involves removal of the cloudy lens and replacement with an artificial one. A special laser (femtosecond laser) is now being used to help make cataract surgery safer and more accurate . The femtosecond laser can also be used to correct astigmatism, an irregular curvature of the cornea, at the time of cataract surgery through a procedure called astigmatic keratotomy (AK). This study is gathering information about the specific laser settings that are used to perform astigmatic keratotomies (AK) during cataract surgery. This information will be used to improve the outcomes of patients that receive cataract surgery with astigmatic keratotomies in the future.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04676451
The ClinicalTrials.gov registry entry for NCT04676451 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 94 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Milton S. Hershey Medical Center, which has 277 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Cataract appearing as the primary indexed condition, and to 1 intervention — of which Femto-AK is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04676451 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
