Study summary

The purpose of this study is to determine the difference in the cornea's response to contact lens placement between healthy and unhealthy eyes. The amount of corneal swelling (corneal thickness) between normal and FECD patients before and after a stress test will be measured and compared.

Read the detailed description

Clarity of the cornea is essential for optimal vision. The endothelium is a layer within the cornea that controls its clarity. Fuchs endothelial corneal dystrophy (FECD) is a progressive disease that affects both eyes in which the endothelium is dysfunctional, causing the cornea to swell and lose its clarity. Because of the vision loss associated with this swelling, corneal transplantation is needed for patients with advanced FECD.

Currently, there is no method to directly measure how well endothelium cells are functioning in patients with FECD. Such a measurement, if it were possible, would allow physicians to identify patients who are at a higher risk of corneal swelling. The goal of this study is to establish a tool to measure and compare the amounts of corneal swelling between normal and FECD patients after a stress test is performed (the wearing of an FDA-approved contact lens.) Data will also be collected regarding how quickly and how well a cornea recovers from swelling in patients with healthy eyes compared to those with FECD.

Study arms

  • Active comparator
    Subjects with Fuch's Endothelial Dystrophy

    Persons with a diagnosis of Fuch's Endothelial Dystrophy will wear a contact lens in an affected eye for three hours.

    Device: Wearing of contact lens

  • Other
    Subjects with healthy eyes

    Persons with healthy eyes will wear a contact lens in one eye for three hours.

    Device: Wearing of contact lens

Interventions

  • DeviceWearing of contact lens

    All subjects will wear a contact lens for three hours. The effect of the lens on the eye (epithelial swelling) will be measured at intervals after the lens is removed.

    Maximum changes in the thickness of the cornea measured before and after the stress test

    Time frame: seven hours

  2. The rate of corneal recovery after the stress test

    The extent of swelling evident at regular intervals during the 3 hours after the stress test

    Time frame: three hours

  3. Time to full recovery from swelling

    The time it takes for the eye to no longer be swollen

    Time frame: three hours
