PURPOSE To analyze and compare the clinical outcomes obtained after cataract surgery with the implantation of a new multifocal toric intraocular lens (IOL) using two different types of corneal incision. METHODS Retrospective study including 64 eyes of 35 patients who underwent surgery with implantation of the AT LISA 909M multifocal toric IOL (Carl Zeiss Meditec) in 2 different ophthalmologic...

Childhood visual impairment due to refractive errors is one of the most common problems among school-age children and is the second leading cause for treatable blindness [1]. Vision 2020: The Right to Sight, a global initiative launched by a coalition of non-government organizations and the World Health Organization (WHO) [2] is to eliminate avoidable visual impairment and blindness on a global...

AIM To describe the visual response to spectacle correction ("refractive adaptation") for children with unilateral amblyopia as a function of age, type of amblyopia, and category of refractive error. METHOD Measurement of corrected amblyopic and fellow eye logMAR visual acuity in newly diagnosed children. Measurements repeated at 6 weekly intervals for a total 18 weeks. RESULTS Data were co...

BACKGROUND This study examined the refractive and visual outcome of wavefront-optimized laser in situ keratomileusis (LASIK) in eyes with low myopia and compound myopic astigmatism ≤ 0.75 diopter (D). METHODS 153 eyes from 153 consecutive myopic patients (74 male, 79 female; mean age at surgery 40.4 ± 10.4 years) who had a preoperative refractive cylinder ≤ 0.75 D and a manifest sphere betwee...

globalization is a worldwide phenomenon. the concept globalization is a very recent term only establishing its current meaning in the 1970s, which emerged from the intersection of four inter related sets of communities of practice, academics, journalists, publishers. this paper models the channels through which globalization affects financial sector development in nigeria. to this end this stud...

We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.

BACKGROUND The purpose of the study was to develop a questionnaire that could quantify the quality of life (QOL) of people with refractive correction by spectacles, contact lenses, and refractive surgery in the prepresbyopic age group. METHODS The questionnaire was developed and validated using traditional methods and Rasch analysis. A 90-item pilot questionnaire was developed through extensi...

The aim of study was to establish which level of myopic refractive error influences visual field defects in automated static perimetry, if these defects are typical, and if optimal correction normalized the visual field. The study included 100 patients (200 eyes) divided into three groups according to the severity of the myopic refractive error: group A (till -3.25 Dsph), group B (-3.50 Dsph to...
