Many myopic patients want to go to the hospital for myopic laser surgery, but when they go to the hospital, they find many ophthalmologists wearing glasses. They wonder but are embarrassed to ask: Why don’t ophthalmologists do myopic laser surgery themselves? First of all, myopia laser surgery is an elective treatment and not everyone needs to undergo it. It is not like malignant tumor removal or fracture fixation and repositioning, which is a procedure that everyone has to undergo. Most of the people who undergo laser surgery for myopia are young people, especially white-collar workers and students, because of the need to change their image, employment recruitment, military recruitment or medical examination for school entrance, while most doctors have stable jobs and need relatively little in this area. Secondly, doctors also because of the need for self-protection. Unlike ordinary people, ophthalmologists are often close to patients, or even zero distance contact, and the conjunctiva is a weak part of the human body surface, some diseases transmitted through body fluids may also be transmitted through the conjunctiva, many foreign ophthalmologists work with protective glasses. For ophthalmologists, myopic glasses can act as protective goggles in a way to protect their health. Last, but not least, ophthalmologists have higher requirements for near vision because of the requirements of delicate surgery. In terms of professional needs, it is better for ophthalmologists to have 300 degrees of myopia so that it is easier to work. After the physical examination of the high school, the doctor’s myopic refraction are below 400 degrees, and ophthalmologists after decades of hard work, learning, technology, experience at the age of 40 years old are beginning to mature, if remove myopic glasses, at this time may have to wear another pair of presbyopic glasses, from this point of view, ophthalmologists undergo myopic laser surgery is not very necessary. Although ophthalmologists rarely undergo myopic laser surgery, the safety and effectiveness of myopic laser surgery has been widely recognized. Ophthalmologists rarely undergo myopic laser surgery, but there are many relatives and friends of ophthalmologists who undergo the surgery, and many doctors from other departments have also undergone the surgery. Now, the volume of myopic laser surgery has exceeded 600,000 per year domestically, while it has reached about 1 million in the United States.
