CPT® Code 0661T

The procedure described by CPT® Code 0661T involves the removal and reimplantation of a nonbiodegradable drug-eluting implant specifically designed for the anterior segment of the eye. This innovative approach utilizes a drug-eluting implant that delivers targeted therapy for various ocular conditions, particularly glaucoma. The implant is engineered to provide a continuous and controlled release of travoprost, a medication that effectively lowers intraocular pressure, which is crucial for managing glaucoma. By bypassing the corneal barrier, this method eliminates the need for patients to adhere to a regimen of eye drops, thereby enhancing treatment compliance and efficacy. The titanium implant consists of a scleral anchor that secures it to the trabecular meshwork, a drug reservoir that holds the medication, and a titrating elution membrane that regulates the release of the drug into the anterior chamber. The procedure is performed through a micro-invasive technique, involving a 2.4 mm incision, allowing for a minimally invasive approach to ocular surgery. The scleral anchor is positioned within the trabecular meshwork and is secured by gentle nudging. When the implant's drug reservoir is depleted, the titanium implant can be removed and replaced using a similar surgical technique, ensuring ongoing treatment for the patient.
