Ophthalmic surgery using light-field microscopy

Abstract

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.

Description

technical field [0001] The present disclosure relates to systems and methods for ophthalmic surgery. Background technique [0002] Eye surgery saves and improves the sight of tens of thousands of patients every year. However, given the sensitivity of vision to even small changes in the eye and the tiny and fragile nature of many ocular structures, it is difficult to perform ophthalmic surgery with even small or unusual reductions in surgical errors or accuracy in surgical technique Small improvements in accuracy can make a huge difference in a patient's vision after surgery. [0003] Microscopic images are used during eye surgery to view small eye structures. Although eye structures are magnified, how closely these images match what normal vision can see will affect how well the surgery works. Monocular microscopy images provide information about the observed object through size, focus, shadows, and occlusions. Three-dimensional (3D) displays now add binocular aberration...

Problems solved by technology

[0007] While the information provided by motion parallax is important, this information is not pre-incorporated into ophthalmic surgical systems (e.g., microscopes)
