Louis Émile Javal was a pioneer in the early history of orthoptics (Figure 1). To anyone knowledgeable about binocular vision, the name Javal conjures up discussions of physiological diplopia, stereoscopes, and fusion training exercises. Javal was a prolific designer of optical devices to use in orthoptic training and ushered in a new era of binocular instrumentation.1–4 Although Wheatstone is ...

Purpose: To compare Orbscan II and Pentacam keratometry readings in terms of their agreement with a manual Javal type keratometer Methods: In this retrospective study, records of patients who had refractive surgery were reviewed. We extracted data of 765 eyes which had keratometry with the Javal keratometer; of these, 577 had Orbscan II and 200 eyes had Pentacam acquisitions. Minimum (min-K) an...

PURPOSE To compare keratometric measurements using a Javal type manual keratometer with IOLMaster in eyes undergoing photorefractive keratectomy (PRK) for myopia. METHODS In this comparative case series, we studied patients aged 21 to 27 years scheduled for myopic PRK. Keratometry was performed preoperatively and three months after the procedure using a Javal type manual keratometer and the I...

PURPOSE To compare the corneal power measurements obtained using different topographic instruments after myopic photorefractive keratectomy (PRK). METHODS Patients with myopia who were candidates for corneal refractive surgery were sequentially included. Pre-PRK and six months post-PRK corneal powers were measured using Javal manual keratometer, Orbscan II, Galilei, Tomey TMS4, and EyeSys 200...

PURPOSE To evaluate postoperative astigmatism with regard to incision-induced astigmatism and deviation in axial alignment with the use of preoperative limbal marking with the Javal keratometer (Haag Streit, Bern, Switzerland) in eyes implanted with the Artisan toric phakic intraocular lens (IOL) (Ophtec, Groningen, The Netherlands). DESIGN Prospective nonrandomized trial. PARTICIPANTS Fift...

Although the term uraemia was first introduced in 1840 by Piorry and L'Heritier, its true nature was disclosed by the work of Widal and Javal (1903). Bright, as early as 1833, though the term uraemia was unknown, recognized that the impregnation of the circulating blood with demonstrable amounts of urea was in some way responsible for a general derangement of the constitution. It is somewhat di...

Dans La solution scientifique de la question sociale, résumés et fragments l’organisation du bonheur, le militant anarchiste individualiste Paraf-Javal expose sa vision changement social. Face à une société capitaliste autoritaire qu’il considère malade, l’anarchiste propose nouvelle organisation sociale épurée ses perversions qui serait alors garante bonheur collectif. Ce repose sur « transfor...
