Brief Summary:
Study Objectives To compare the efficacy and safety of surgical treatment (PRK) versus non-surgical treatment of anisometropic amblyopia in children who have failed conventional treatment due to non-compliance or non-response.
Synopsis of Study Design
The study consists of two phases:
1. A Patching Run-In Phase during which all participants are treated for at least 8 weeks with continued refractive correction (with spectacles and/or contact lenses) and patching prescribed 42 hours per week (averaging 6 hours daily) until no further improvement over 2 consecutive visits at least 4 weeks apart or the vision no longer meets eligibility criteria.
2. A Randomized Trial Phase, beginning after no further VA improvement in the patching run-in phase and qualifying amblyopia is still present, during which the participant is assigned to either surgery with PRK and patching prescribed 2 hours per day or to non-surgical treatment with continued refractive correction (with spectacles and/or contact lenses) and patching prescribed 2 hours per day.
Detailed Description:
The study is evaluating the efficacy of surgical treatment with PRK versus non-surgical treatment of anisometropic amblyopia in children who have failed conventional treatment. The primary analysis will be a treatment group comparison of the change in BCVA in the amblyopic eye at the 8-month primary outcome visit. For participants wearing a contact lens, the BCVA will be the visual acuity tested in the contact lens rather than in spectacles (or trial frames).
