Vision Improvement for Legally Blind Dry AMD Patients

Vision Improvement for Legally Blind Dry Age-Related Macular Degeneration Patients

This retrospective observational study is intended to assess the feasibility of using a nonsignificant risk device for vision improvement for legally blind dry AMD patients.

This retrospective observational study is intended to assess the feasibility of using a nonsignificant risk device for vision improvement for legally blind dry Age-Related Macular Degneration patients. 12-month follow-up examinations will be used to assess the amount of vision improvement and its dependence on device parameters.

IInclusion Criteria:

• Male or Female
• Any race
• Patient is at least 50 years old.
• Patient must have dry AMD in the study eye.
• Patient is legally blind due to AMD - i.e., has corrected distance visual acuity (CDVA) of 20/125 or worse (45 letters; logMAR ≥ 0.80) in the study eye.
• Patient has normal corneal surface topography on videokeratography (i.e., without distorted or unclear corneal mires).
• Patient is not a contact lens wearer.
• Patient is willing and able to comply with all examinations.
• Patient must be competent to sign an informed consent form before study entry.

Exclusion Criteria:

• Visually significant cataract in the study eye
• Presence of a visually significant posterior capsule opacity if prior cataract surgery has been performed in the study eye
• Any visually significant disease process in any ocular structure other than AMD that would affect vision in the study eye
• Previous corneal surgery in the study eye
• Presence or history of any other condition or finding that, in the opinion of the investigator, makes the patient unsuitable as a candidate for study participation or may confound the outcome of the study
