OBJECTIVE To examine the long-term safety and efficacy of hyperopic automated lamellar keratoplasty (H-ALK) for correction of primary hyperopia and for consecutive hyperopia following overcorrected myopic refractive surgery. METHODS A prospective study was done on 67 eyes of 50 consecutive patients who underwent H-ALK between March 17, 1993, and August 18, 1995. Hyperopic automated lamellar k...

PURPOSE The aims of the study were to develop guidelines for prescribing spectacles for patients with moderate to severe hyperopic amblyopia and to demonstrate how emmetropization progresses. METHODS Children with hyperopic amblyopia who had a spherical equivalent of ≥ +4.0 diopters (D) or more were included, while those who had astigmatism of > 2.0 D or anisometropia of > 2.0 D were excluded...

Hyperopia is the most common refractive condition in childhood. There are few studies on moderate hyperopia and associated factors. This study aims to investigate the prevalence of moderate hyperopia and associated factors among school children. A cross-sectional study comprising 1,032 students attending 1st to 8th grades at two public schools was conducted in a Southern Brazilian urban area in...

AIM The purpose of this study was to investigate the prevalence of hyperopia and strabismus among a paediatric population with malocclusions. MATERIALS AND METHODS From a total of 322 consecutive patients observed at the department of Orthodontics and Gnathology, Dental Clinic, University of L'Aquila, 176 were selected for the study according to the exclusion criteria. Pretreatment diagnos...

PURPOSE To investigate the association of hyperopia greater than +3.25 diopters (D) with amblyopia, strabismus, anisometropia, astigmatism, and reduced stereoacuity in preschoolers. METHODS Three- to five-year-old Head Start preschoolers (N = 4040) underwent vision examination including monocular visual acuity (VA), cover testing, and cycloplegic refraction during the Vision in Preschoolers S...

Understanding the role of peripheral defocus on central refractive development is critical because refractive errors can vary significantly with eccentricity and peripheral refractions have been implicated in the genesis of central refractive errors in humans. Two rearing strategies were used to determine whether peripheral hyperopia alters central refractive development in rhesus monkeys. In i...

PURPOSE To describe a topographically guided photorefractive keratectomy technique for the management of secondary hyperopia following radial keratectomy. METHODS A retrospective study was carried out in patients where a topographically guided photorefractive keratectomy technique was performed for the management of secondary hyperopia following radial keratectomy. The patients had preoperati...
