Measuring the heterophoria: Agreement between two methods in non-presbyopic and presbyopic patients.

PURPOSE To establish whether the cover test and von Graefe methods are interchangeable in a non-presbyopic and presbyopic population. METHODS We performed a prospective study on a sample of 127 non-presbyopic subjects between 20 and 45 years old and 56 presbyopic between 40 and 78 years old. Distance and near vision phoria were measured using the von Graefe method (VG) and cover test (CT). We...

Accommodative Ability in Pre-presbyopic Diabetic Patients

Introduction: To compare various accommodative parameters in prepresbyopic diabetic patients with age-matched healthy individuals. Materials and Methods: Study population consisted of 32 younger-onset diabetic patients (30-40 years of age) and 28 age-matched healthy normal individuals. Using the best correction for distance visual acuity (20.20 by Snellen chart), multiple accommodative ability ...

Presbyopic correction today

Presbyopia is the most common refractive error in patients older than 40 years. The loss of accommodation results in difficulty with near vision. Surgical means to correct this accommodative deficiency include scleral expansion band and anterior ciliary sclerotomy, which enhances the movement of the ciliary body. Monovision in which the non-dominant eye is left with some myopia for near vision ...

Presbyopic correction on the cornea

PURPOSE The aim of this systematic review was to synthesize and appraise the evidence of the benefits of presbyopic correction on the cornea for visual function. SUMMARY Comprehensive search was conducted in MEDLINE using keywords like "presbylasik", "presbyopic refractive surgery", "corneal pseudoaccommodation" and "corneal multifocality". We reviewed corrected and uncorrected visual acuitie...

Lens fluorescence and accommodative amplitude in pre-presbyopic and presbyopic subjects.

Accommodative amplitude (AA; the difference, measured in diopters, between the near and far points of vision) declines steadily with age such that, by midlife, most individuals are unable to focus clearly on near objects and, thus, are said to be presbyopic. Conversely, intrinsic lens fluorescence (LF) increases steadily with age. Previous studies have suggested that AA and LF are negatively co...
