Corneal shape in hyperopia [PDF]

Australasian journal of optometry, The, 1998
Background: A trend towards decreased peripheral corneal flattening with increasing myopia has recently been demonstrated. The present study was conducted to determine whether corneal asphericity also varies significantly with hyperopic refractive error.

Refractive Surgery for Hyperopia

Journal of Refractive Surgery, 2000
ABSTRACT PURPOSE: To determine the efficacy, stability, and predictability of refractive surgery for hyperopia using four different procedures: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), implantation of a phakic intraocular lens (PIOL), and removing the transparent lens with IOL implantation.

Lamellar Keratoplasty for Hyperopia

Journal of Refractive Surgery, 1996
ABSTRACT PURPOSE: Lamellar keratoplasty for hyperopia (automated lamellar keratoplasty for hyperopia) can correct hyperopia by weakening the cornea with a deep lamellar resection. The safety and efficacy of the procedure is uncertain. METHODS: Twenty-four eyes of 17 patients underwent hyperopic lamellar keratoplasty using the ...

Surgical Correction of Hyperopia

Survey of Ophthalmology, 2006
Surgical attempts to correct hyperopia have yielded varying results over the last 130 years. These techniques include the reshaping of the cornea through incisions, burns, or lamellar cuts with removal of peripheral tissue; the addition of central inlays; laser ablations; and the replacement of the crystalline lens.

Effects of Induced Hyperopia

American journal of optometry and physiological optic, 1978
ABSTRACT Hyperopia of 1.00, 1.50, and 2.00 D was induced in 42 subjects by means of concave lenses. A significant decrease in performance on a standard intelligence test occurred with the highest‐power lenses. Symptoms induced indicate that the results are applicable to hyperopia.

Epikeratophakia for the treatment of hyperopia

Journal of Cataract and Refractive Surgery, 1989
Nordan epikeratophakia technique (NET) is described for the treatment of hyperopia and the results in eight eyes are reported (mean = +5.09 +/- 0.85 diopters preoperatively and -2.09 +/- 1.22 diopters postoperatively). The Nordan epikeratophakia technique is a modification of Kaufman-McDonald epikeratophakia with advantages that are described. Data are
