How to treat high myopia?
High myopia refers to a degree of nearsightedness above 1000 degrees. High myopia brings great troubles to people, even affecting their diet and preventing them from participating in high-intensity physical exercise. It may also lead to complications such as retinal detachment, cataracts, macular hemorrhage, macular degeneration, vitreous liquefaction degeneration, and glaucoma. The treatment of high myopia has always been a major challenge in ophthalmology. With the advent of refractive lens exchange surgery, after extensive clinical practice, it has now become a better option for correcting vision in patients with extremely high myopia. The refractive state of the eyeball is mainly determined by the refractive power of the eyeball and the length of the eye axis. In cases of nearsightedness, the lengthening of the eye axis causes the light to focus in front of the retina, making it difficult for patients to see distant objects clearly. During refractive lens exchange surgery, a concave lens specifically tailored to the patient is implanted into the eyeball to change the focal point of the light so that it accurately focuses on the retina, achieving the purpose of correcting nearsightedness. Refractive lens exchange surgery maintains the integrity and accommodative function of the eye's physiological structure, has a larger optical zone, eliminates aberrations, and has a wider range of adaptability compared to corneal refractive surgery. Post-surgery, patients experience less discomfort, faster vision recovery, stable refraction, and no regression phenomenon.
