Myopia is categorized into low myopia, moderate myopia and high myopia according to the degree of myopia, and myopia above 600 degrees is called high myopia. Usually, myopia below 1000 degrees can be considered for traditional laser myopia correction if the cornea is thick enough. However, if the patient’s myopia is higher, or due to the patient’s thin cornea can not do laser myopia correction surgery, because the too thin cornea after surgery is undoubtedly a high risk factor. For these patients we can choose to do intraocular lens implantation to correct their vision. For many patients with ultra-high myopia, the surgery has resulted in unexpectedly good vision, as well as cosmetic improvements. To a certain extent, these patients have gained unprecedented confidence and better mental state. Of course, this procedure is still available to patients who have reached the age of 18. For older patients, such as those over the age of 45, a cautious attitude is required, due to the significant decline in the patient’s adjustment after this age, and tends to the onset and development of age-related hyperopia. Some patients begin to experience aging and clouding of the crystalline lens around the age of 50, making it less meaningful to perform this surgery. If you do reach this age, you may want to consider IOL replacement surgery if you are particularly keen to get rid of your glasses.
