Abstract: The invention relates to an intraocular lens comprising at least one pharmaceutically-acceptable photochromic polymer that enables all or part of the intraocular lens to change colour reversibly when exposed to light.

Abstract: The invention relates to a sizing composition intended to be applied to mineral fibers, especially glass or rock fibers, which contains at least one polycarboxylic acid and at least one polyamine. It also relates to a method of preparing the composition, to its use for sizing mineral fibers for the purpose of forming, in particular, thermal and/or acoustic insulation products, and to the products obtained.

Abstract: The invention relates to a composition for treating and/or preventing snoring, comprising at least one thermogelling polymer that includes water-soluble units as well as units having a lower critical demixing temperature in water. Said composition has the specific feature of being liquid in the packaging thereof and becoming a gel upon contacting mucus membranes at 37° C. Thermogelling makes it possible to precisely target the area to be treated while avoiding any running or migration of the material, and makes the sprayed composition difficult to wash off, thus increasing the duration of the presence thereof in the treatment area.

Abstract: The invention relates to novel compounds of formula (I): in which R1, R2 and R3, identical or different, independently represent: hydrogen a halogen a C1 to C15 hydroxy or hydroxyalkyl group a C1 to C15 linear or branched alkyl group a, b and c independently lying between 0 and 5. R4 is linked to the naphthalene unit at position 1, 2 or 3 via a —CH2—O— bond and represents: either a divalent group which is (co)polymerisable with a monomer; in which case d lies between 1 and 3 or a monovalent group which is (co)polymerisable with a monomer; in which case d is equal to 2 or 3 and R5 is linked to the naphthalene unit at position 1, 2 or 3 and represents: hydrogen, a halogen, a C1 to C15 hydroxyalkyl group, a C1 to C15 linear or branched alkyl group, and e is an integer lying between 0 and 2 and such that d+e=3. It also relates to the method for synthesising these compounds and to their use for the manufacture of photochromic or photosensitive polymers.

Abstract: The invention concerns an implant forming an intraocular lens comprising a central optical part, a globally circular outline, at least partly made of a flexible material and a haptic part, at said optical part periphery, made at least partially of a rigid material. Said implant has a single-piece structure. The implant rigid material is a shape modified by at least one process selected among chemical reactions and polymerisation reactions of the starting flexible material, for example based on PMMA-PHMA, cross-linked by adding a multifunctional agent such as diethyleneglycol dimethacrylate.
