Official title
Identification of Optimum Spectacle Prescriptions for Patients With Down Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study tests the hypothesis that objectively derived spectacle prescriptions based on wavefront aberration measurements of the eyes of individuals with Down syndrome can provide an improvement in visual acuity over that obtained with spectacle prescriptions based on standard clinical prescribing techniques. The objectively derived prescriptions are derived using strategies to optimize retinal image quality as measured by image quality metrics, and thus these prescriptions will be referred to as metric-derived.
