Retinal split is a fundus disease caused by congenital developmental abnormalities or high myopia, etc. Whether a patient with a retinal split can undergo cataract surgery depends on the size of the retinal split as well as the presence or absence of complications, and whether the patient meets the criteria for cataract surgery. If the patient’s retinal split is mild, retinal detachment has not yet occurred, and the fundus lesions do not have much effect on vision loss. However, cataracts are severe enough to cause the patient’s vision to decline, and the patient can have cataracts treated surgically to improve vision, and it also facilitates the patient’s fundus examination. When the retinal cleavage is large and the patient also complicates retinal fissure, if the patient’s lens clouding is not very obvious, it is not recommended to directly perform cataract surgery, the patient can first laser treatment of retinal fissure, and then perform cataract surgery. It is recommended that cataract patients seek medical attention in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
