If myopia worsens in a 50-year-old patient, the cause needs to be identified first. If it is caused by growth of the eye axis, posterior scleral reinforcement surgery can be considered for treatment in cases where the growth of the eye axis is large, or cataract surgery can be performed if it is caused by cataract lens expansion. Under normal circumstances, the growth of myopia gradually stabilizes after adulthood, but some patients still have myopia growth even in old age, which may be related to poor eye habits and other factors. Patients in their 50’s who are experiencing a rapid increase in myopia due to rapid axial growth can be considered for posterior scleral reinforcement surgery to control their myopia. In addition, attention should be paid to correcting bad eye habits. For patients in their 50s, if the increase in myopia is caused by cataracts that swell the lens, they can go to the ophthalmology department of the hospital for a slit lamp microscopy. If the turbidity of the lens is severe, it can be treated by cataract surgery. Specific treatment should be carried out in a professional medical institution after consultation and follow the doctor’s instructions, usually to develop correct eye habits, avoid prolonged close-distance use of the eyes.
