DESC:TITLE OF THE INVENTION: PORTABLE ROBOTIC DEVICE FOR THE EXAMINATION OF HUMAN EYE AND METHOD OF OPERATION THEREOF
FIELD OF THE INVENTION
The present disclosure is generally related to a robotic device for the examination of human eye. Particularly, the present disclosure is related to a portable and robotic ophthalmological device for the examination of anterior and posterior segment of a human/patient’s eye through automated and remote control operations.
BACKGROUND OF THE INVENTION
From recent studies, it has been found that, the number of eye-care practitioners is comparatively low, when compared to the population needing eye care, with most of the practitioners practicing in urban areas. Thus, the rural population does not have as much access to eye-care when compared to the urban population. The lack of care takers, inadequate diabetes and blood pressure management, affordability, and inadequate clinical staffing were mentioned to be the important barriers in providing eye health care, as documented in the literature.
Even in the current technology era, with the availability of advanced devices/instruments, it is essential for eye care practitioners to be present physically to examine their patients. The expenses involved in transporting experts and the devices/instruments, and the time constraints, make eye health care in rural areas even more expensive.
Human eye slit lamps are very useful for examining or imaging the anterior segment of eyes, but require a physical presence to operate the device. Similarly, for posterior examination of the eyes, fundus imaging camera and Indirect Ophthalmoscopy are known to be the important instruments for detecting various conditions affecting the eye (retina), including, but not limited to, diabetic retinopathy and macular degeneration.
Commercial fundus camera imaging instruments are available in clinics and hospitals for ophthalmologists. They are fixed and more expensive. These instruments capture the image of the fundus through their camera and the optics present within the instruments. Such instruments can only be operated by trained professionals. Another commonly used instrument worldwide by ophthalmologists is the indirect ophthalmoscope; this instrument is a head mounted device containing optics and a light source. This device has to be manually operated with an additional 20 Dioptre lens, which should be aligned in focus with the indirect ophthalmoscope to get the fundus examination done for a patient. The ophthalmologist interprets the diagnosis and records manually in the patients’ medical records.
While conventional fundus imaging apparatus require manual operation, there has been considerable effort expended towards automating specific functions of such imaging apparatuses, including, but not limited to, automated positioning and alignment of the patient’s eye to the instrument via near infra-red and pupil alignment technology, automated backup of stored fundus images, etc.
Even though many improvements are happening in fundus camera design, there are still significant hurdles to widespread acceptance and usability of these devices. Among disadvantages noted with current apparatus/devices/instruments, the major disadvantage is the complexity in the operation.
There is, therefore, a need in the art for a portable robotic device for the examination of anterior and posterior segments of a human eye through automated and remote control operations, which overcomes the aforementioned drawbacks and shortcomings.

After completion of the examination of one eye, the eye examining module (5) moves to examine the next eye. A remote ophthalmology support is provided with the help of the display unit (9), when the robotic eye examining device (100) is connected with a network/internet. A health care practitioner can connect with the device (100) remotely, operate the device (100) from the remote location, and interact with the patient/user (11) through the display unit (9). The images captured during the eye examination can be shared with the health care practitioner. The health care practitioner examines the captured images, and shares a report or to the patient (11). The device can also be connected with a printer to print the reports. During the automated operation, the images captured during the eye examination are analyzed by the AI based analytics and operating module to identify the presence of any ocular disorders, and a report/feedback is provided to the patient (11).
