Ophthalmic surgery using light-field microscopy
A system and method for ophthalmic surgery in which a light field camera is used to capture a digital image of the surgical field including the eye. The digital image is used to create image information and directional information, which is then used to from a three dimensional (3D) image with motion parallax.
1. A system for performing ophthalmic surgery, the system comprising:
a magnifying lens through with light reflected from an eye undergoing ophthalmic surgery passes;
a light field camera that receives light that has passed through the magnifying lens and that coverts the light to digital information;
a processing resource that receives the digital information from the light field camera and creates image information and directional information from the digital information without using extrapolation; and
a three dimensional (3D), motion-parallax-enabled visual display that receives the image information and directional information and uses it to display a 3D image of the eye, wherein the perspective of the 3D image of the eye moves with the eye of a viewing user; and
a head-tracking component which tracks the viewing user's head and sends head-tracking data to the processing resource, wherein the processing resource further adjusts the perspective of the 3D image on the visual display based on the head-tracking data.
2. The system of claim 1 , wherein the magnifying lens comprises a direct contact lens or an indirect lens.
3. The system of claim 1 , wherein the light field camera comprises a microlens array and a photosensor configured such that the microlens array projects microimages onto the photosensor.
4. The system of claim 3 , wherein the photosensor comprises a pixel array and each pixel in the pixel array receives light from only one microlens.
5. The system of claim 3 , wherein the photosensor comprises a pixel array and at least one pixel in the pixel array receives light from at least two microlenses.
6. The system of claim 3 , wherein the microlens array is located at a focal point of the magnifying lens.
7. The system of claim 3 , wherein the light field camera further comprises a main lens and the microlens array is located at a focal point of the main lens.
8. The system of claim 1 , wherein the 3D visual display comprises glasses or goggles.
9. The system of claim 1 , wherein the motion parallax-enabled screen comprises an auto stereoscopic display.
10. The system of claim 1 , wherein the motion parallax-enabled screen comprises a single screen display.
11. The system of claim 1 , wherein the motion parallax-enabled screen comprises a multiview display.
12. The system of claim 1 , further comprising a second 3D display.
