People with myopic eyes have the following feelings: wearing glasses fogs up in winter and slips in summer; the first thing you do when you wake up every day is to look for your glasses; the world is a mosaic when you take off your glasses; the most insecure time is when you are swimming; and it's always a kind of torment to watch 3D movies. Because of these many inconveniences, more and more people want to solve the problem by doing myopia correction surgery.
According to the development of medical technology, there are more and more ways to correct myopia, including non-surgical methods such as wearing framed glasses and corneal contact lenses, and surgical methods such as laser myopia correction surgery and crystalline lens implantation. Laser myopia correction surgery mainly includes superficial corneal surgery (PRK, LASEK, Epi-LASIK), lamellar surgery (LASIK, SBK, FS-LASIK), and the newest procedure of femtosecond laser small incision lens extraction (SMILE). The range of refractive power applicable to each surgical modality is different, and the most suitable surgical modality can usually be selected according to the actual situation.
Clinical evaluation of the effect of laser myopia correction surgery is some objective indicators, such as postoperative visual acuity, refractive error, and so on. In recent years, more and more myopic patients are not only concerned about the safety and effectiveness of the surgery, but also more concerned about the impact of the surgery on their quality of life.
At present, it is generally recognized at home and abroad that laser myopia correction surgery improves visual function and increases the convenience of daily life after surgery. The sense of being recognized by others and increased self-confidence are the main factors for improved quality of life after surgery. The so-called vision rebound refers to refractive regression, which is one of the postoperative complications of laser myopia correction surgery and one of the main concerns of people currently choosing myopia surgery. The incidence of refractive regression has been reported differently in various studies, and is generally considered to be around 5%.
