Patients with cataracts combined with dislocated lenses can usually be treated with a single surgery, but the exact treatment plan depends on the patient’s condition. Lens dislocation is usually caused by congenital developmental abnormalities or trauma to the eye. The dislocated lens may push the iris toward the cornea, closing the angle of the atrium and causing secondary glaucoma, while the dislocated lens itself may become cloudy and form a cataract. This condition can usually be treated with a single surgery, but the exact treatment plan depends on the patient’s condition and should be chosen according to the doctor’s advice. Surgery involves removal of the dislocated lens and implantation of an IOL. The depth of the anterior chamber can then be deepened and the glaucoma is usually relieved. If extensive adhesion or destruction of the atrial angle is considered prior to surgery, a combined trabeculectomy can be performed at the same time, and the patient’s condition can usually be controlled after the above combination of surgical treatments. It is recommended that patients with lens dislocation should seek timely hospitalization to evaluate their condition and follow the doctor’s instructions for treatment.
