A diagnostic and therapeutic contact lens is provided for use with biomicroscopes for the examination and treatment of structures of the eye. The lens comprises a contacting surface adapted for placement on the cornea of an eye, two reflecting surfaces, and a refracting surface. A light ray emanating from the structure of the eye enters the lens and contributes to the formation of a correctly oriented real image. The light ray is reflected in an ordered sequence of reflections, first as a negative reflection in a posterior direction from an anterior reflecting surface and next as a positive reflection in an anterior direction from a posterior reflecting surface. The light ray contributes to forming the image of the structure of the eye either anterior to the lens or within the lens and proceeds along a pathway to the objective lens of the biomicroscope used for stereoscopic viewing and image scanning.

A novel telehealth video conferencing system (process) that is designed to enable the patient user to have a real-time or near real-time 2 way tele-conference/consult including the transfer of patient specific biometric information with a health care provider team (one or more health care providers simultaneously, i.e. a team consisting of a pharmacist, physician, mental health provider, clinical lab, mental health provider, orthopedist, podiatrist, dentist, clinical specialist, etc. . . . ) located remotely from the telehealth digital/video patient user portal. The present invention, the IPWP is an interactive-digital health care provider network to patient portal designed to provide patients with the same level of quality care that they would expect to receive if they were physically in a multispecialty doctor or health care providers' (nurse practitioner, physician assistant, dentist, ophthalmologist, orthopedist, podiatrist, medical specialty clinic, hospital, etc. . . . ) office. However, the patients that utilize the IPWP will interact with their health care provider/s on a computer/notebook/smart device screen/monitor via existing secure digital web or cellular camera technology in a mobile or stationary, enclosed/private HIPP compliant environment at a retail pharmacy or a pharmacy supported location (workplace, educational facilities, retail stores, etc. . . . that have an in-house, adjacent or an electronic dispensing pharmacy). Current statistics demonstrate that 80% of primary care provider visits result in the health care provider writing a script for medication. Medication management is critical to safe, effective quality care and has been an issue of health care reforms Accountable Care Organization concept since 2009. In order for the patient to receive comparable care to what they would receive in a multispecialty provider/doctor's office with an onsite pharmacy, the IMP will combine the use of existing biometric sensor technologies (i.e. Strain Gauge Tech, IR Thermometer, etc.) in order for the system to take patient real time biometric information such as height, weight, blood pressure, pulse, EKG, blood glucose, body temperature, etc. . . . as well as identify the patient positively by both video capture and biometric scanning (fingerprint, iris scan, driver's license photo, etc. . . . ). It also has the capability to upload information from certain glucose readers in order for the physician to better assess a patient's blood sugar levels and may incorporate the use of magnified micro camera technology and lighting to look at a patient's microanatomy (ear canals, nasal passages, skin conditions, color and eye examination, etc. . . . ). In addition to the use of sensor technology the IPWP can incorporate the use of antimicrobial materials or technologies (copper ions, silver ions, UV light, HEPA filters, etc. . . . ) to reduce the communication of disease from patient to patient. The monitor, web camera, and other vital components will be designed to be permanently or temporarily (mobile system) located within a secure/private enclosure at a pharmacy or pharmacy supported location (private kiosk, room, booth, enclosure, space, etc. . . . ). All patient information and electronic forms will be transmitted via a secure encrypted web based digital or cellular portal to multiple providers as needed simultaneously for a seamless 3-way (or more) consultation/communication. The IPWP will be linked to a smartphone/computer/Internet/web app that will allow the patient to view availability and schedule appointments at their local pharmacies IPWP or alternatively on a walk-in, as needed basis. Lastly, the unit will be equipped with electronic payment technologies such as card (swipe) readers, etc. . . . to capture/collect payment from credit cards, PayPal and debit cards for all health care services provided including, but limited to co-pays, payments, prescriptions, lab test, etc. . . . .

In summary the ability of the patient portal system to provide real time, multiple simultaneously communicating health care providers with real time biometric information (including the onsite or tele pharmacist) is a novel process not limited to the single provider video/audio access currently patented. This new dimension to telehealth promises a telehealth experience that at a minimum matches the diagnostics ability and access of a multispecialty clinic or traditional hospital setting while exceeding the clinical/diagnostic ability of a single health care provider's office or clinic that is more accessible at a 50% reduced cost and resulting in better health outcomes.

An inverted real image forming opthalmoscopic contact lens provides for viewing and treating structures within an eye. The lens comprises a contacting surface adapted for placement on the cornea of the eye, a concave annular anterior reflecting surface, a convex annular posterior reflecting surface, and two non-reflective portions. A first non-reflective portion is positioned along the lens axis and proximate to the convex annular posterior reflecting surface. A second non-reflective portion is positioned along the lens axis and proximate to the concave annular anterior reflecting surface. A light beam emanating from the structure of the eye enters the lens and contributes to the formation of an inverted real image of the structure through an ordered sequence of reflections of the light beam, first in a posterior direction from the anterior concave reflecting surface and next as a negative reflection in an anterior direction from the convex posterior reflecting surface.

A diagnostic and therapeutic contact lens is provided for use with the slit lamp or other biomicroscope for the examination and treatment of the structures of the eye including that of the fundus and anterior chamber. The lens comprises a contacting portion adapted for placement on the cornea of an examined eye, two reflecting surfaces and a refracting portion. Light rays emanating from structures within the eye pass through the cornea and contacting portion of the lens and first reflect from the anterior reflecting surface as a positive reflection in a posterior direction. Following the first reflection the light rays reflect as a positive reflection in an anterior direction from the posterior reflecting surface to a refracting portion through which the light rays exit the lens. The lens focuses the light rays to produce a real image of the examined structures of the eye anterior of the lens or within the lens or element of the lens while optimally directing the light rays to the objective lens of the slit lamp or other biomicroscope for stereoscopic viewing and image scanning.
