Benefits of technology

The presented solution is a new way to determine the physical location of an anatomical feature in a retina using a specialized eye imaging device. This helps the surgeon quickly and accurately locate the feature during surgery. The solution uses an OCT image and a display device to show a visual representation of the feature and its location in the eye. Overall, this technology helps improve the precision of surgery and can potentially improve the outcome of eye surgeries.

Problems solved by technology

However, the surgeon can find it difficult to identify where in the patient's eye anatomical features shown in the OCT image are located.

Embodiment Construction

[0023]In the following description, specific details can be set forth describing certain embodiments. It will be apparent, however, to one skilled in the art that the disclosed embodiments may be practiced without some or all of these specific details. Specific and / or illustrative, but not limiting, embodiments can be presented herein. One skilled in the art will realize that other material, although not specifically described herein, can be within the scope and spirit of this disclosure.

[0024]The present disclosure describes devices, systems, and methods of encoding point-to-point location correspondence between the OCT image and the surgical field into a location indicator. The location indicator can be positioned in the field of view of the surgical microscope used by the surgeon to visualize the surgical field. The OCT image and a key corresponding to the location indicator can also be viewable within the field of view of the surgical microscope. The location indicator and the k...

Abstract

An ophthalmic visualization system can include a computing device in communication with an OCT system configured to scan a surgical field to generate an OCT image. The computing device can be configured to determine locations within the surgical field corresponding to locations within the OCT image. The ophthalmic visualization system can also include an indicator mechanism in communication with the computing device and a surgical microscope configured to image the surgical field. The indicator mechanism can be configured to cause a location indicator to be positioned within a field of view of the surgical microscope. The location indicator can graphically represent the locations within the surgical field corresponding to the locations within the OCT image.

Description

BACKGROUND[0001]Technical Field[0002]Embodiments disclosed herein can be related to ophthalmic visualization systems. More specifically, embodiments described herein can relate to providing a location indicator in a field of view of surgical microscope during an ophthalmic surgical procedure. The location indicator can allow a surgeon to correlate locations within an optical coherence tomography (OCT) image with locations in the surgical field, such as a patient's eye.[0003]Related Art[0004]Ophthalmic microsurgical procedures can require precision cutting and / or removing of various body tissues of the patient's eye. A user, such as a surgeon or other medical professional, can visualize the patient's eye using a surgical microscope. Image-guided surgical intervention can be possible with technologies such as optical coherence tomography (OCT). OCT can be a noninvasive, high resolution, cross-sectional imaging modality. The OCT image can guide the surgeon during the ophthalmic surgica...
