We consider the question whether pupils from the lower social strata perform better in private government-dependent schools than in public or private-independent schools, using the PISA 2000 data on European high schools. In the eighty’s, Coleman and Hoffer (1987) found in the USA that the performance of these pupils was better at religious schools than at comparable public schools. Dronkers an...

Nowadays is well stated that after keratorefractive surgery, without a special correction, the intraocular lens (IOL) power is usually inaccurate. The article by Kenneth J. Hoffer1 which appeared in the first JanuaryMarch 2010 issue of the Journal of Emmetropia is an excellent review of recently published studies that analyze and try to solve the problems to calculate IOL power in eyes with pri...

The shapes of different organs can be explained largely by two fundamental characteristics of their epithelial rudiments - the pattern of branching and the rate of proliferation. Glial-cell-line-derived neurotrophic factor (GDNF) has recently been implicated in the development of metanephric ureteric epithelium (Pichel, J. G., Shen, L., Sheng, H. Z., Granholm, A.-C., Drago, J., Grinberg, A., Le...

Aims: To study the refractive outcome of cataract surgery employing IOLMaster biometry data and to compare it with that of applanation ultrasonography in a prospective study of 100 eyes that underwent phacoemulsification with intraocular lens implantation. Methods: The Holladay formula using IOLMaster data was employed for the prediction of implanted intraocular lenses (IOLs). One month after c...

The goal of this study is to assess the effect pupillary dilation on predicted post-operative  refraction  (the Plano or least minus refraction) and recommended intraocular lens (IOL) power calculated by using third generation fourth formula measure difference  between pre  and   post   pupil  dilation  on ACD. This   study included 40 eyes with cataract will undergo phacoemulsification divided...
