Candidacy Assessment
The telescope prosthesis is indicated for monocular implantation in patients greater than or equal to 75 years of age with stable severe to profound vision impairment (best-corrected distance visual acuity of 20/160 to 20/800) caused by bilateral central scotomas associated with End-Stage age-related macular degeneration (AMD). However, as with any treatment, the telescope implantation procedure is not right for every patient with End-Stage AMD who meets this description. A number of criteria are associated with the indication that must be met before a patient is considered a candidate for the telescope prosthesis. In general, to meet these criteria the patient must have:
- Stable, untreatable age-related macular degeneration (AMD) disease in both eyes (end-stage; geographic atrophy or disciform scar)
- No active wet AMD (no sign of active choroidal neovascularization in either eye)
- Not been treated for wet AMD in the previous six months
- No sign of eye disease other than well-controlled glaucoma; cataract must be present
- Visual acuity poorer than 20/160, but not worse than 20/800 in both eyes
- Achieved at least a 5-letter improvement on the ETDRS chart with an external telescope
- Agreed to participate in a visual training/rehabilitation program after surgery
Determining whether or not a potential candidate meets these criteria is the basis for CentraSight treatment program screening evaluation and selection and involves all members of the CentraSight Team.
