About

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.

Full 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.

Enrollment: 17 patients

Sex: All

Ages: 50 to 100 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. • Male or female
2. • Any race
3. • Patient is at least 50 years old
4. • Patient has diagnosed late stage dry age-related macular degeneration in one or both eyes.
5. • Treated eyes were pseudophakic at the time of treatment.
6. • 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).
7. • Patient CDVA records are available at baseline and at 12 month post-treatment.

Exclusion criteria

1. • Corneal disease or disorder in either eye.
2. • Increased intraocular pressure (above 20 mm Hg), glaucoma or history of glaucoma.

3. • Presence or history of any other condition or finding that, in the opinion of the investigator, makes the patient unsuitable for retrospective observational study.
