1. Indications

The ocular telescope prosthesis is indicated for patients with end-stage age-related macular degeneration (AMD), a condition characterized by significant loss of central vision. This procedure is specifically aimed at improving visual acuity in individuals who have experienced a decline in their ability to see clearly due to this degenerative eye disease.

• End-stage age-related macular degeneration (AMD) The primary indication for the insertion of an ocular telescope prosthesis is to enhance vision in patients suffering from advanced stages of AMD, where central vision loss is prominent.

2. Procedure

The procedure for the insertion of an ocular telescope prosthesis involves several critical steps that ensure the successful implantation of the device. Initially, a large incision, approximately 12 mm, is made in either the cornea or sclera to provide access to the internal structures of the eye.

• Step 1: Incision A 12 mm incision is created in the cornea or sclera, allowing the surgeon to access the eye's interior. This incision is necessary for the subsequent steps of the procedure.
• Step 2: Removal of the crystalline lens or intraocular lens prosthesis Following the incision, the surgeon carefully removes most of the crystalline lens or any existing intraocular lens prosthesis that is located behind the iris. This step is crucial to prepare the eye for the implantation of the telescopic lens.
• Step 3: Preservation of the posterior capsule The posterior capsule, which is the elastic lens capsule, is intentionally left in place. This structure plays a vital role in supporting the weight of the newly implanted telescopic lens.
• Step 4: Securing the telescopic lens The ocular telescope prosthesis is then secured to the posterior capsule using sutures that are threaded through the haptic loops of the lens. This ensures that the lens remains stable and properly positioned within the eye.

3. Post-Procedure

After the procedure, patients can expect to notice improvements in their vision during the immediate post-operative period. The ocular telescope prosthesis allows for enhanced visual acuity, enabling patients to focus on both near and far objects using their natural eye movements. Post-operative care may include monitoring for any complications and ensuring proper healing of the incision site. Patients are typically advised on follow-up appointments to assess the success of the procedure and to make any necessary adjustments to their visual aids.
