Cataract and silicone oil removal can usually be solved in one operation, usually the silicone oil is removed first, then cataract surgery, but the specific surgical plan is related to the patient’s condition . Silicone oil injected into the vitreous cavity may cause clouding of the lens, resulting in the formation of secondary cataracts or aggravation of existing cataracts. If the patient’s condition permits, after removing the silicone oil, the patient can continue to undergo cataract extraction and IOL implantation, solving two problems in one operation, but the specific surgical plan is related to the patient’s condition. For one week after surgery, patients should avoid getting sewage into the eye to prevent infection. Patients also need to avoid rubbing their eyes to prevent the IOL from becoming dislocated, and avoid strenuous exercise for one month to prevent the surgical incision from splitting. It is recommended that patients following cataract and silicone oil removal surgery follow the doctor’s instructions for care, regular checkups, and prompt medical attention when discomfort occurs.
