High myopia is usually defined as eyes with -600 degrees or more and an eye axis of 26mm or more. The aberration produced by thick lenses disrupts the quality of your vision, especially when you enter middle age (55 years old), and the nucleated cataracts that plague your eyes and the changes in the macular structure of the fundus may affect your visual function even more. To get rid of this dilemma as early as possible, my advice to you is to go to the hospital to evaluate your visual function status as a whole once, and if it has indeed been affected, after getting detailed examination results, you can consider appropriate anterior cataract surgery, and if there is a combined macular structure lesion, you can also have a combined surgery (cataract extraction + macular surgery) to rebuild your visual function. What exactly does visual function include? In addition to visual acuity, there is contrast sensitivity, night vision and color vision.
