  • Publication number: 20240050621
    Abstract: The present disclosure presents sealant compositions which can be used in the treatment of an ocular surface injury and methods of treating an ocular surface injury in a subject in need thereof. The sealant compositions can include methacrylated hyaluronic acid (MeHA); GelMA; optionally, poly(ethylene glycol) diacrylate (PEGDA); and a visible light-activated photoinitiator. The methods include applying a sealant composition to an applicator; placing the applicator containing the sealant composition onto a surface of the eye of a subject, wherein the surface of the eye has or is suspected of having the ocular surface injury; and photo-crosslinking the sealant composition by exposing the applicator and the sealant composition to a visible light, for example, a visible light having a wavelength of about 400 nanometers (nm) to 800 nm.

  • Patent number: 11844571
    Abstract: The technology described in this document can be embodied in systems and computer-implemented methods for determining a score representing an amount of staining of the cornea. The methods include obtaining a digital image of the cornea stained with a tracer material, receiving a selection of a portion of the image, and processing, by a processing device, the selection to exclude areas with one or more artifacts to define an evaluation area. For each of a plurality of pixels within the evaluation area, a plurality of Cartesian color components are determined and a hue value in a polar coordinate based color space is calculated from the components. An amount of staining of the cornea is then determined as a function of the hue value. The methods also include assigning a score to the evaluation area based on the amount of staining calculated for the plurality of pixels.
