Ocular Dimensions and Refraction in Tibetan Children
Optometry and Vision Science, 1995ABSTRACT A cross‐sectional study of 404 Tibetan children (212 males, 192 females) aged 6 to 16 years was conducted in the Bouda region of Kathmandu, Nepal in April, 1992. Examination procedures included retinoscopy (1% cyclopentolate HCI), keratometry A‐scan ultrasonography, and video ophthalmophakometry. The mean refractive error was

This is an exceptionally interesting and valuable book, written by one who has evidently had considerable experience in all the practical details of prescribing glasses, from the initial refraction done in the office to the grinding of the lenses and the fitting of frames.

"CHANGES IN OCULAR REFRACTION"
Archives of Ophthalmology, 1933To the Editor. — I observe that in Dr. Edward Jackson's paper on "Changes in Ocular Refraction," which appears in the last Bulletin of the American College of Surgeons , he does not mention my three papers on the rotation of the axis in astigmatism, though he refers quite fully to the subject. The first of my contributions was published in the British

Segregation Analysis of Ocular Refraction and Myopia
Human Heredity, 1985Segregation analysis of ocular spherical refraction data using a unified model resulted in rejection of a Mendelian hypothesis of genetic transmission in nuclear families of both Japanese and European ancestries. Similar analyses of families which included at least 1 myope gave no evidence for the hypothesis that myopia is determined in part by a major

to determine frequencies of refractive errors in Zairian blacks and to investigate the influence of race upon refraction.we examined the records of all patients seen at the department of Ophthalmology from 1963 to 1972. Refraction was measured by objective (skiascopy) or subjective methods.we found 4326 patients with ametropia, about 16% of the total ...

Influence of laser polarization on ocular refractive parameters after refractive surgery
Optics Letters, 2004We provide an adjustment factor for ablation algorithms used in photorefractive laser surgery that takes into account how laser polarization in reflection losses affects the cornea. We evaluate the influence of this factor on corneal radius and asphericity after surgery, showing that it is significant for visual performance (effective visual acuity is ...

Ocular surface and refractive surgery
Acta Ophthalmologica, 2011AbstractPurpose Dry eye represents nowadays the most common complication after PRK and even more frequent after lasik. Preoperative dry eye constitutes a risk factor for postoperative severe dryness; that it why it appears crucial to detect and treat surface disorder before the surgery.Methods We will remind the list and hierarchy of tests available ...

Ocular refraction with body orientation.
Aviation, space, and environmental medicine, 1989Body inversion is used experimentally to raise the intraocular pressure (IOP). Psychophysical and electrophysiological methods of assessing visual function in artificially raised IOP are generally influenced by the clarity of the retinal image. It is therefore essential to be aware of any changes in ocular refraction induced by changes in body ...
