The iris retractor is mainly used for hooking and pulling the iris tissue during ophthalmic surgery. The iris retractor can be used in iris adhesion cataract surgery as well as cataract with subluxation ultrasonic emulsification. Iris adhesions occur after cataract surgery and affect the surgical outcome, so pupil dilation is often required. Iris puller is the most commonly used method of dilation, which can minimize iris damage and maximize pupil shape and function after surgery. Cataracts with subluxation of the lens are complex and difficult to treat. Protecting the integrity of the posterior lens capsule during surgery can minimize vitreous detachment. The use of an iris retractor aid can increase the surgical field of view, maintain anatomical stability, and prevent intraoperative lens damage. It is recommended that patients after cataract surgery follow the doctor’s instructions for care, regular review, and timely consultation after discomfort occurs.
