Phase:
Study type: Observational

"GoCheck Kids" has added to its iPhone 7+ smart phone with flash concentrator a non-accommodating glow box fixation target.

NCT ID: NCT03610997 Active, not recruiting - Hyperopia Clinical Trials

Photorefractive Keratectomy for Severe Anisometropia and Isoametropia Associated With Amblyopia

Start date: January 1, 2001
Phase: N/A
Study type: Interventional

Photorefractive keratectomy (PRK) with excimer laser has been used successfully to treat myopia, hyperopia, and astigmatism in adults for over 35 years. Children with high refractive errors that go untreated will develop severe amblyopia. PRK can normalize high refractive errors and potentially improve the visual acuity in affected children. The purpose of this study is to investigate whether children with high anisometropia or isoametropia with amblyopia that are nonresponsive to standard therapy and receive PRK develop better longterm visual acuity.
