Patient: The patient is a male, 83 years old, who had cataract surgery in both eyes at a local hospital in 1999, and his vision reached 1.0 after surgery. He Yongqi, Cataract Center, Beijing Tongren Hospital: Hello! It is better to review the problem at the local hospital to determine the problem initially. If it is a posterior cataract, then YAG laser treatment can be considered. Patient: Can the lens be replaced or repaired after cataract surgery? Patient: Cataract postoperative low vision Description of the disease (onset, main symptoms, hospital visited, etc.): Patient, male, 83 years old, had cataract surgery in both eyes in 1999. Currently, the left eye has mild posterior cataract with 0.3 vision and the right eye has 0.1 vision before surgery. Due to preoperative myopia and flash, this factor was not considered when the IOL was replaced at that time, and the postoperative vision is still 0.1 Can Can I get a new IOL or repair the original one to improve my vision? Thank you! He Yongqi, Cataract Center, Beijing Tongren Hospital: Hello! We need to determine the structural status of the lens and its surrounding area. We can consider YAG laser treatment first, and we can consider wearing frame glasses to correct myopia and astigmatism.
