Abstract
Systems and methods for surveying the sclera are provided. In some aspects, a method for generating a design for a prosthetic lens for an eye of a subject includes arranging an eye of a subject at a distance from a plurality of illumination sources and a plurality of imaging devices, projecting light onto the eye of the subject using the illumination sources, acquiring image data of the eye of the subject and the light using the plurality of imaging devices, generating a three dimensional map of the eye, including the sclera, using the image data; and designing, using the three dimensional map of the eye for the lens that fits over a cornea of the eye to engage the sclera and form a fluid pocket between the prosthetic lens that surrounds the cornea.
Claims20
A system for mapping an exterior surface of an eye of a subject comprising:
- a support structure configured to engage the subject and position an eye of the subject in a predetermined position;
- at least two illumination sources configured to direct light on to the eye of the subject in the predetermined position;
- a plurality of imaging devices separated from and directed toward the support structure to acquire image data of the eye of the subject when the light is positioned thereon;
- and
- a processor configured to receive the image data of the eye of the subject from the plurality of imaging devices and generate a three-dimensional map of the eye, including a sclera, from the image data.
A method for generating lens for an eye of a subject comprising:
- arranging an eye of a subject at a distance from a plurality of illumination sources and a plurality of imaging devices;
- projecting light onto the eye of the subject using the illumination sources;
- acquiring image data of the eye of the subject and the light using the plurality of imaging devices;
- generating a three-dimensional map of the eye, including the sclera, using the image data;
- and
- designing, using the three-dimensional map of the eye, a lens that fits over a cornea of the eye to engage the sclera and form a fluid pocket between the lens that surrounds the cornea.
A method for surveying sclera of an eye comprising:
- arranging an eye at a distance from a plurality of imaging devices;
- acquiring image data of the sclera of the eye using the plurality of imaging devices, wherein each point on the sclera is imaged at least twice;
- dividing the sclera of the eye into multiple overlapping swaths;
- determining a three-dimensional shape for each of the multiple overlapping swaths by using the acquired image data comprising at least two images for each point;
- combining the multiple overlapping swaths to form a three-dimensional map of the sclera of the eye using the image data for overlap areas of the multiple swaths;
- and
- designing, using the three-dimensional map of the sclera of the eye, a lens that fits over a cornea of the eye to engage the sclera and form a fluid pocket between the lens that surrounds the cornea.
