Visual acuity and refraction with a diffractive multifocal toric intraocular lens. J Cataract Refract Surg 2013; 39: 1507-1518Bellucci R, Bauer NJC, Daya SM, et al.Visual acuity and refraction with a diffractive multifocal toric intraocular lens[J]. J Cataract Refract Surg, 2013, 39(10): ...
Complete ophthalmic history and eye exam with attention to pinhole visual acuity (corrects most low to moderate refractive errors to the 20 / 25 to 20 / 30 level), manifest (undilated) and cycloplegic (dilated) refraction, retinoscopy, pupils, keratometry, cornea, lens, and ophthalmoscopy. ...
The meaning of VISUAL ACUITY is the relative ability of the visual organ to resolve detail that is usually expressed as the reciprocal of the minimum angular separation in minutes of two lines just resolvable as separate and that forms in the average hum

Visual acuity should be measured asbest corrected distance visual acuity. A recent refraction is required to obtain thebest corrected visual acuity. Although the traditional distance used to measure visual acuity was 20 feet or 6 meters, distance vision can be measured at any distance from 3 feet...
Patients with different ocular disorders, showed grating acuity outside the normal range, as expected.Refraction findings were in line with other studies. Astigmatism data, however, differed from previous reports since the type of astigmatism most frequently found was with-the-rule axis (93% of ...
When an optometrist, an optometric physician or an ophthalmologist examines and performs a refraction on someone’s eyes, it is optimal for the object being viewed (presumably a visual acuity chart) to be as far away as possible from the patient. This is so that the incoming rays of light ...
refraction. If these are unavailable, a pinhole will improve most mild to moderate refractive errors in cooperative patients (Fig. 2.1B). Patients with subnormal acuity despite best refracted correction should also be tested with pinholes, which may further resolve some refractive errors (irregular ...
