Overview
Brief Summary
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device.
Detailed Description
The purpose of this study is to assess the vision improvement achieved by patients with late stage dry age-related macular degeneration who received corneal treatments by a low vision aid device. Patient records for patients with at least 12 months follow-up will be analyzed to determine measures of vision improvement including best spectacle-corrected distance and near visual acuity. Analyses will include descriptive statistics and correlation between outcomes and baseline characteristics.

Eligibility Criteria
Inclusion Criteria
- •Male or female
- •Patient is at least 50 years old
- •Patient has diagnosed late stage dry age-related macular degeneration in one or both eyes.
- •Treated eyes were pseudophakic at the time of treatment.
- •Patient had moderate to severe baseline vision impairment with best spectacle-corrected distance visual acuity (CDVA) of 20/63 or worse (decimal = 0.317 or less; logMAR greater than or equal to 0.50) in the treated eye(s).
- •Patient CDVA records are available at baseline and at 12 month post-treatment.
Exclusion Criteria
- •Corneal disease or disorder in either eye.
- •Increased intraocular pressure (above 20 mm Hg), glaucoma or history of glaucoma.
- •Presence or history of any other condition or finding that, in the opinion of the investigator, makes the patient unsuitable for retrospective observational study.
