Accommodative 3D Virtual Reality Magnification Micro Display Lense and Camera System

Tech ID: dan001109



Endoscopes and exoscopes are used for a multiplicity of applications in medicine. Three-dimensional (3D) scopes were recently introduced and allow for a sense of depth not possible with two-dimensional (2D) systems. Unfortunately, displays that present 3D images on a 2D screen may cause ocular fatigue, headaches, nausea, and other problems for the viewer due to the vergence-accommodation conflict, which is the distance mismatch between vergence, or the way the eyes line up when looking at the object, and accommodation, or the focus on an object by the lenses of the eyes. When viewing a 2D screen, one's eyes accommodate to the screen but converge or diverge on a different distance. Additionally, in order to view the image with a 3D effect, the viewer must be oriented exactly 90 degrees to the screen, which is a problem since physicians must move throughout an operation. While many solutions have been proposed to address these problems with some success, many are too expensive and complex for widespread implementation.


Technology Description

Dr. Moise Danielpour from the Neurosurgery Department at the Cedars-Sinai Medical Center has developed a magnification microdisplay lens system that addresses a number of issues associated with currently available 3D medical imagers and display systems. The system incorporates one microdisplay on each lens of a pair of glasses. The use of multiple microdisplays allows for optical correction that creates 3D depth perception and a sharp image focus.


Stage of Development

Concept only



• Addresses the vergence-accommodation conflict, thereby reducing issues associated with the use of 3D medical imaging systems, such as ocular fatigue, headaches, and nausea.

• Does not require physicians to consciously move their head to obtain a 90-degree angle to the screen

• Can be configured to match the operative focal distance, angle, and orientation of each specific surgeon



• Depiction of real-time 3D images during medical procedures
