The CPT® Code 0660T refers to the implantation of a nonbiodegradable drug-eluting system within the anterior segment of the eye, utilizing an internal approach. This procedure involves the insertion of a specialized implant designed to deliver targeted intraocular therapy for various ocular conditions, particularly glaucoma. The implant is engineered to provide a continuous and long-term release of travoprost, a medication that effectively reduces intraocular pressure, which is crucial for managing glaucoma. By bypassing the corneal barrier, this method eliminates the reliance on patient compliance with traditional eyedrop regimens, thereby enhancing treatment efficacy. The titanium implant consists of a scleral anchor that secures the device to the trabecular meshwork, a drug reservoir that holds the medication, and a titrating elution membrane that controls the release of the drug into the anterior chamber. The procedure is performed through a small 2.4 mm incision, allowing for a minimally invasive approach to view the anterior chamber angle via an ab interno technique. This innovative method not only improves patient outcomes but also streamlines the management of glaucoma by providing a consistent therapeutic effect without the need for daily medication administration.

The implantation of the anterior segment intraocular nonbiodegradable drug-eluting system is indicated for the treatment of various ocular conditions, particularly those associated with elevated intraocular pressure, such as:
The procedure for the implantation of the drug-eluting system involves several critical steps to ensure proper placement and functionality of the device:
Post-procedure care involves monitoring the patient for any signs of complications, such as infection or increased intraocular pressure. Patients may be advised to avoid strenuous activities and follow specific instructions regarding eye care. The titanium implant is designed to remain in place until the drug reservoir is depleted, at which point a similar micro-invasive surgical procedure can be performed for removal and reimplantation of the device. Regular follow-up appointments are essential to assess the effectiveness of the treatment and to ensure the ongoing health of the eye.
