CPT® Code 66986

The procedure described by CPT® Code 66986 refers to the exchange of an intraocular lens (IOL), which is a surgical intervention typically performed to address refractive errors that may arise after cataract surgery. An intraocular lens is a synthetic lens implanted in the eye to replace the natural lens that has been removed during cataract surgery. In some cases, the initially placed IOL may not provide the desired visual acuity or may lead to complications, necessitating its exchange. The procedure involves several critical steps to ensure the safe and effective removal of the existing lens and the placement of a new one. The surgical approach includes creating an incision in the cornea to facilitate access to the anterior chamber of the eye, where the IOL is located. The use of viscoelastic substances is essential during this procedure, as they help maintain the shape of the anterior chamber and protect the eye's internal structures. The meticulous dissection of the anterior capsule from the IOL is performed to ensure that the lens can be safely removed without damaging surrounding tissues. Ultimately, this procedure aims to restore optimal vision by replacing the IOL with one that better meets the patient's refractive needs.
