I have been in contact with so many myopic patients and their families at work, and I have communicated with them a lot. I understand their anxiety and urgency to seek medical treatment, and I would like to work with them. I would like to share with you some of the misconceptions that I’ve shared with them, and see if you think so too. Myopia is not a big deal. If you wear glasses now anyway, you won’t have myopia after surgery in the future. Myopia consists of two parts, one is the eye as an optical system, when the adjustment is relaxed, the parallel light into the eye after focusing on the retinal plane in front, so in the retina into a blurred image, before the performance of no correction is far naked eye vision is reduced. Another part of myopia is the myopic structural changes in the eye, the most obvious of which is the growth of the eye axis. Of course, in some special cases of myopia, this also includes dislocation of the lens and special shapes of the lens, but the growth of the eye axis is the most obvious and common, especially the change in the length of the vitreous cavity, so doctors usually use the length of the eye axis as an objective indicator of myopia progression. Also accompanying the growth of the eye axis are changes in the retina, choroid, and optic papilla, such as the thinning of the retinal choroid. Therefore, myopia is not only an optical concept, but also a series of anatomical, physiological, and pathological changes in the eye that accompany this optical change. So generally we can classify myopia into physiological myopia and pathological myopia, which means that there is only an optical problem and no ocular pathology occurs. However, pathological myopia means that not only optical problems but also organic pathologies occur in the eye, such as retinal detachment, macular degeneration and hemorrhage, glaucoma, etc. The higher the myopia, the longer the eye axis, the more pathological changes occur, and pathological myopia is one of the top three factors that cause blindness in our country. So we can see that as an optical problem, we can use optical means to correct it. After using concave lens to disperse light, parallel light can be imaged on the retina to see if you can see something, and also depends on the integrity of your retina, choroid, macula, and optic nerve. If atrophy occurs in the retinal choroid because of the growth of the eye axis, even if the optical system is corrected, you still can’t see anything. So doctors can correct your prescription to nothing by various means, such as excimer laser surgery (usually under 1000 degrees), and IOLs for crystalline eyes to correct higher heights, but the eye changes associated with myopia are always present. So even if you don’t wear glasses anymore, myopia is still there. Therefore, our clinical treatment goals for myopia must include not only optical correction, but also the control of myopia and the treatment of some related pathological conditions. How to set the treatment goal and the treatment strategy to match the goal varies from person to person. The ocular changes of myopia are irreversible, so when you are nearsighted, your eye is a myopic eye, and it has nothing to do with wearing glasses or not.
