Patient viewing angle ophthalmic operation simulation method based on virtual reality technique

Abstract

The invention discloses a patient viewing angle ophthalmic operation simulation method based on a virtual reality technique. Feelings for a TPRK (transepithelial photorefractive keratectomy) corneal refractive operation and a corneal pterygium operation are simulated from a patient viewing angle in an ophthalmic operation, so that a patient preoperatively knows operation processes and sensual experience in the operation, the method helps the patient to effectively match with a doctor in the operation, an operation process is smoother, tension feelings of the patient are eliminate, intra-operative experience of the patient is improved, postoperative satisfaction of the patient is improved, understanding and familiarizing of the patient can relieve operation difficulty form a doctor angle, and the method fills in the blank of application of the virtual reality technique to medical aspects based on the patient angle.

Description

technical field [0001] The invention specifically relates to the field of medical assistance technology, in particular to a method for simulating ophthalmic surgery from a patient's perspective based on virtual reality technology. Background technique [0002] The ophthalmic surgery market is currently dominated by pterygium and TPRK refractive surgery. [0003] According to a joint survey by the Ministry of Health and the Ministry of Education in 2014, the incidence of myopia in my country's population is 33%, far exceeding the world's average myopia rate of 22%. . Among them, the average incidence rate of adolescents with a high incidence of myopia is as high as 50% to 60%. At present, the incidence of myopia in primary schools, junior high schools, and high schools in China is 25%, 70%, and 85%, respectively. China is currently one of the countries with the highest incidence of myopia in the world, and the number of myopia is the first in the world. As the degree of myo...

Problems solved by technology

[0004] During the previous PRK surgery, the applicant found that the existing PRK surgery process has the following disadvantages: When the patient's cooperation is poor and the eyeballs are frequently turned, the operator needs assistants to assist the operation when loosening the corneal epithelium, such as leakage when the patient exerts a lot of force Alcohol may cause some damage to the ocular surface

[0012] Since the degree of cooperation of the above-mentioned ophthalmic surgery patients has a great influence on the surgical effect, the virtual surgical reality system based on the patient's perspective has not yet appeared, which belongs to a blank area and has not been touched by others.
