Outcome Measures
Primary Outcomes (1)
Best spectacle-corrected distance visual acuity (CDVA) changes from baseline to 24 months post-Tx
CDVA will be measured using ETDRS letter scoring both pre-Tx and post-Tx with follow-up to 24 months post-Tx
Through study completion, an average of 2 years
Secondary Outcomes (1)
Visual Function Questionnaire (VFQ)-25 quality of life assessment
Through study completion, an average of 2 years
Study Arms (1)
Treatment arm
EXPERIMENTALPatients will be treated by the Optimal Acuity Clear-K Low Vision Aid System.
Interventions
The treatment involves irradiation of the cornea with low energy light in a treatment pattern that produces corneal shape change.
Eligibility Criteria
You may qualify if:
- Male or Female
- Any race
- Patient is at least 50 years old.
- Patient has diagnosed dry or wet age-related macular degeneration in one or both eyes, as verified by a complete ocular examination by a retina specialist; the full ocular examination, including optical coherence tomography (OCT) measurements, should be part of the patient's file.
- Wet AMD eyes should have an inactive disease state (i.e., there is no clinical or OCT evidence of wet AMD disease activity).
- Patient is pseudophakic or is phakic with no clinically significant cataract in eye(s) to be treated..
- Patient has manifest refraction, spherical equivalent (MRSE) between -1.50 D to 1.50 D in eye(s) to be treated.
- Patient has moderate to severe vision impairment due to dry age-related macular degeneration with best spectacle-corrected distance visual acuity (CDVA) of 20/80 or worse (decimal = 0.25 or less; logMAR ≥ 0.60) in the better eye.
- Patient has CDVA of 20/400 or better (decimal = 0.05 or greater; logMAR ≤ 1.30) in the worse eye.
- Patient has normal corneal surface topography on videokeratography (i.e., without distorted or unclear corneal mires) in both eyes.
- Patient is not a contact lens (CL) wearer.
- Patient is willing and able to comply with all examinations.
- Patient must be competent to sign an informed consent form before study entry.
You may not qualify if:
- Corneal disease or disorder in either eye;
- Corneal topographic astigmatism greater than 2.00 D (mean value within 3.0 mm optical zone);
- Pathological retinal morphology in either eye that completely affects the entire 10° (3 mm diameter) of the retina centered on the foveola (as evaluated by optical coherence tomography);
- Potential Visual Acuity (PVA) in both eyes that is not improved by at least three lines compared to CDVA;
- Increased intraocular pressure (above 20 mm Hg), glaucoma or history of glaucoma; and
- 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 that may confound the outcome of the study.
