PURPOSE To analyze and compare the intraoperative and postoperative outcomes of cataract surgery performed with two different femtosecond laser platforms. METHODS Randomized controlled prospective intraindividual comparative study including 90 eyes of 45 patients aged between 61 and 86 years. All eyes underwent bilateral cataract surgery assisted with femtosecond laser technology. Eyes were r...

Purpose Femtosecond laser-assisted cataract surgery (FLACS) is an increasingly common procedure. Most laser systems require corneal applanation and thereby increase intraocular pressure (IOP). The purpose of the present study was to evaluate the IOP changes that occur during the FLACS procedure performed using the Catalys femtosecond laser system. Methods IOP was measured by direct cannulatio...

An inspection of the active site region of metallo-enzymes leads to two conclusions. (i) Individual attacking groups usually have uncommon physical properties. (ii) The active site region is cooperatively linked with a large part of the enzyme. Such an interaction is common to heterogeneous catalysts but is absent in homogeneous catalysts. It is concluded that the energetics of catalysis requir...

In femtosecond laser-assisted cataract surgery, the parameter such as horizontal spot spacing and energy level can be adjusted. Although there have been several studies reported on various laser systems, showing the effects of varying energy levels and horizontal spot spacing on lens capsulotomy cut edges, none have been reported on the Catalys laser system (Abbott Medical Optics, Inc., Santa A...

A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under clay-catalyzed as an inexpensive and eco-friendly catalyst using grindstone chemistry. Significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously...

La Société Française d’Accompagnement et de soins Palliatifs (SFAP) a lancé en février 2021 un portail ressources pour aider les enseignants la médecine scolaire à accompagner situations où fin vie, mort le deuil font effraction au sein l’école. Revenant sur genèse du projet, nous soutenons que ce site web catalysé une dynamique...
