Radial Thermokeratoplasty for the Correction of Hyperopia
Journal of Refractive Surgery, 1990ABSTRACT: Hyperopic thermokeratoplasty involves making controlled thermal burns In the corneal stroma in a radial pattern up to a premarked clear zone. It steepens the central cornea and reduces the hyperopia. A series of 117 radial thermokeratoplasty eyes done in the Soviet Union were analyzed. Mean preoperative hyperopia of +5.27 diopters (range = +0.

Laser in situ keratomileusis for hyperopia
Journal of Cataract and Refractive Surgery, 1998To examine the initial results of laser in situ keratomileusis (LASIK) for hyperopia.Arzt für Augenheilkunde, Mannheim, and Photoingenieur, Wendelstein, Germany.This retrospective study evaluated 43 eyes having hyperopic LASIK using the Automatic Corneal Shaper (Chiron Vision) and the MEL 60 excimer laser (model 94, Aesculap-Meditec).

To the Editor. —Marmor has recently reported in theArchives(89: 419,1973) an interesting case of transient hyperopia in diabetes. In his comment on the refractive changes, Dr. Marmor correctly states that the refractive and accommodative changes in diabetes are poorly understood.

[Esotropia and hyperopia corrected].
[Zhonghua yan ke za zhi] Chinese journal of ophthalmology, 2012The subgroups of esotropia exist. The full optical correction of the hypermetropic refractive error is theoretically conclusive. The full correction further defined the diagnosis of three forms of esotropia. The earlier viewpoint that the full optical correction of the hypermetropia will decrease the accommodative normal demand or the accommodation is ...

Hyperopia is predominantly axial in nature
Current Eye Research, 1998Myopia has been found to be predominantly axial in nature, i.e. myopic eyes have longer than normal axial lengths, with corneal radius variations having only a small influence on the magnitude of the refractive error. In this study we assess whether a similar relationship exists for hyperopia.Biometric data were collected on 57 subjects with either ...

Acquired Hyperopia with Choroidal Folds
Ophthalmology, 1980Six healthy adults suddenly developed a unilateral or bilateral hyperopic shift in refractive error of up to 6 diopters. Fundi of affected eyes showed typical choroidal folds. Visual acuity was improved to normal or near normal by plus lenses, and refraction and fundus appearance have remained stable for up to 23 years.

To the Editor. —Previous authors have disagreed on how the blood glucose affects the refractive state of the lens. 1,2 The mechanism probably involves a number of factors including the level and speed of cortical and nuclear hydration, the overall lens shape, and the lens position. Definitive experimental data are not yet available.

Correction of hyperopia with intracorneal implants
Journal of Cataract and Refractive Surgery, 2002To evaluate the safety and efficacy of intracorneal lenses as a surgical alternative for the correction of hyperopia.Al-Azhar University, Cairo, Egypt, and Louisiana State University Eye Center, New Orleans, Louisiana, USA.PermaVision lenses (Anamed Inc.) were implanted in the left eye of 20 albino rabbits that were followed for 6 months by confocal ...
