as well. In the United States, some companies allow patients to complete an online visual exam and within 24 hours receive a prescription from an optometrist valid for eyeglasses, contact lenses, or both. Some US states such as Indiana have attempted to ban these companies from doing business. Telesurgery Remote surgery (also known as telesurgery) is the ability for a doctor to perform surgery on a patient even though they are not physically in the same location. It is a form of telepresence. Remote surgery combines elements of robotics, cutting-edge telecommunications such as high-speed data connections, telehaptics and elements of management information systems. While the field of robotic surgery is fairly well established, most of these robots are controlled by surgeons at the location of the surgery. Remote surgery is remote work for surgeons, where the physical distance between the surgeon and the patient is immaterial. It promises to allow the expertise of specialized surgeons to be available to patients worldwide, without the need for patients to travel beyond their local hospital. Remote surgery or telesurgery is performance of surgical procedures where the surgeon is not physically in the same location as the patient, using a robotic teleoperator system controlled by the surgeon. The remote operator may give tactile feedback to the user. Remote surgery combines elements of robotics and high-speed data connections. A critical limiting factor is the speed, latency and reliability of the communication system between the surgeon and the patient, though trans-Atlantic surgeries have been demonstrated. Teleabortion Telemedicine has been used globally to increase access to abortion care, specifically medical abortion, in environments where few abortion care providers exist or abortion is legally restricted. Clinicians are able to virtually provide counseling, review screening tests, observe the administration of an abortion medication, and directly mail abortion pills to people. In 2004, Women on Web (WoW), Amsterdam, started offering online consultations, mostly to people living in areas where abortion was legally restricted, informing them how to safely use medical abortion drugs to end a pregnancy. People contact the Women on Web service online; physicians review any necessary lab results or ultrasounds, mail mifepristone and misoprostol pills to people, then follow up through online communication. In the United States, medical abortion was introduced as a telehealth service in Iowa by Planned Parenthood of the Heartland in 2008 to allow a patient at one health facility to communicate via secure video
