Patient: Our toddler was two years old (November 2011) when we went to the hospital for a pediatric fundus screening and found cataracts (mild clouding of the embryonic nuclei of both crystals), followed by an eye ultrasound (with examination report) and a three-day atropine prescription followed by an optometric diagnosis of high myopia of 1500 degrees in both eyes. We did not find that his vision affected his normal life and play. At present, the near vision of the right eye is 0.2 and the left eye is 0.05 measured by the instrument, while the distance vision is not measured because the child is not cooperative. The measurement at home is about 0.1 to 0.2. I am sorry to bother you in your busy schedule. I have an urgent question for you: In my child’s case of bilateral anterior leukodystrophy with 2000 degrees of high myopia, is it necessary to install an IOL at the same time as removing the lens? Thank you for your reply. Liu Yufu, Cataract Center, Beijing Tongren Hospital: Hello! One is to remove the cataract surgically, wear corrective glasses after surgery, and implant an IOL at an opportune time; the other is to remove the cataract surgically and implant an IOL at the same time, but the disadvantage of the latter is that the child’s eye is still changing, and the IOL refractive error is a fixed value, so there will be some under-correction problems slowly. Patient: Hello, Director Liu! If we are going to have surgery, do we need to have another ultrasound before we go to the hospital? Or do we need to do it again at the hospital after we are notified of the hospitalization? Liu Yufu, Cataract Center, Beijing Tongren Hospital: Hello! You can do it after coming to the hospital.
