After vitrectomy, patients may experience complications such as corneal edema, concurrent cataract, and secondary glaucoma. 1. Corneal edema: If the density of corneal endothelial cells is low, patients may experience corneal edema after vitrectomy. If the condition is mild, it may subside on its own, while patients with severe condition may need to undergo corneal endothelial transplantation. 2. Complicated cataract: after vitrectomy, patients may be induced to develop complicated cataract, and patients can have cataract ultrasonic emulsification combined with IOL implantation. 3. Secondary glaucoma: secondary glaucoma is a common complication after vitrectomy, mainly due to intraocular inflammation or hemorrhage after vitrectomy, resulting in increased intraocular pressure. It is recommended that vitrectomy patients follow the doctor’s instructions for care, regular review, and timely consultation after discomfort occurs.
