Many myopia patients want to go to the hospital for myopia laser surgery, but when they get to the hospital, they find that many ophthalmologists are wearing glasses. They are puzzled but embarrassed to ask: why don't ophthalmologists do myopia laser surgery themselves?

First of all, myopia laser surgery is one of several myopia correction schemes at present (other schemes include frame glasses, contact lenses, orthokeratology, intraocular lens implantation and lens replacement), which belongs to a selective treatment and not everyone needs to accept it. Unlike resection of malignant tumor or fixed reduction of fracture, it is an operation that everyone has to accept. At present, young people generally accept laser surgery to treat myopia, especially white-collar workers and students. Most of them have the need to change their image, find a job, be a soldier or have a physical examination at school, while doctors have relatively stable jobs and relatively few requirements.

Secondly, doctors also need to protect themselves. Different from ordinary people, ophthalmologists often have close contact with patients, even zero contact, and conjunctiva is the weak part of human body surface, and some diseases transmitted by body fluids may also be transmitted through conjunctiva. Many ophthalmologists abroad wear protective glasses when they work. For ophthalmologists, myopia glasses can play the role of protective glasses and protect their health to a certain extent.

Finally, and most importantly, because of the requirements of fine surgery, ophthalmologists have higher requirements for myopia. From the professional needs, it is best for an ophthalmologist to have 300 degrees myopia, which is more convenient to work. After the college entrance examination, doctors' myopia diopters are basically below 400 degrees, while ophthalmologists, after decades of hard study, begin to mature their knowledge, skills and experience at the age of 40. If they take off their nearsighted glasses, they may have to wear another pair of reading glasses. From this point of view, an ophthalmologist with myopia of about 300 degrees does not need to undergo myopia laser surgery.

Although some ophthalmologists have not received myopia laser surgery, the safety and effectiveness of myopia laser surgery have been widely recognized by everyone. World table tennis champion Deng Yaping, American golfer Tiger Woods and Britain's Prince William all had corneal refractive surgery. In 2007, the United States approved astronaut candidates to undergo femtosecond laser corneal refractive surgery.
