Abstract: Medical device for preserving explanted corneas, serving as a “viewing chamber”, comprising a sealed outer main case (2) which contains a container (3) for preserving and viewing a cornea which comprises a vessel (4) which inside it forms a preserving chamber, (11), a supporting unit (12) for a corneoscleral disc positioned in the preserving chamber (11), and a first lid (5) removably joinable or joined to the vessel (4); the medical device (1) being ready for use and also comprising a first locking ring (18) which is joinable or joined to both the first lid (5) and to the vessel (4), outside them, and is breakable or deformable; wherein when the first lid (5) is joined to the vessel (4) and the first locking ring (18) is joined both to the first lid (5) and to the vessel (4), in an intact and non-deformed condition, the first locking ring (18) prevents removal of the first lid (5) from the vessel (4), whereas in a broken or deformed condition, the first locking ring (18) allows removal of the first lid (5) f

Abstract: A dye molecule having the structure (I): where R1 is an SO3? group bound to a hydrogen H atom or to another atom or to an ammonium NH4 group or to a lysine salt or to an arginine salt or to a different monovalent cation, and R2 is an SO3? group, in particular for making dye preparations for use in methods for the treatment of the bodies of humans or animals, for example for dyeing the internal limiting membrane ILM and/or epiretinal membranes EPRM in a surgical method which involves subsequent removal respectively of the ILM and/or of the EPRM; as well as a dye preparation having a density higher than 1.01 g/cm3 and comprising at least one dye and at least one agent for increasing its density which is a polymer with the empirical formula (C12H22O11.C3H5ClO)n, and structure (II).

Abstract: A vitrectomy apparatus comprises a containment body (3), at least one supply device (4), (5) which can be fixed to an eyeball (6) and/or moved by an operator, feeding means (7) for the controlled feeding of at least one operating fluid, at least partly mounted in the containment body (3) and in turn comprising at least one main pipe (8) which is or can be connected to the supply device (4), (5), and at least one control unit (21) operatively connected at least to the feeding means (7) for controlling their operation. The vitrectomy apparatus (1) also comprises means for varying the temperature (11) of the operating fluid, being coupled with the feeding means (7) and/or with the supply device (4), (5), for varying the temperature of the operating fluid, the control unit (21) also being connected to the means for varying the temperature (11) in order to control their operation. In particular, the means for varying the temperature (11) can act as heating means (12), and comprise one or more Peltier cells (15).

Abstract: An ophthalmic surgical method comprising a step of at least partly removing the vitreous humour, which also comprises a step of highlighting the vitreous to be removed using a coloured composition which selectively highlights the vitreous, allowing a distinction between the vitreous and the other structures of the eye, said distinction facilitating vitreous removal, wherein the coloured composition comprises a polymeric dye comprising at least one backbone to which at least one reactive dye is chemically linked; in a preferred embodiment the polymeric dye being a blue dextran.

Abstract: A kit of tamponing liquids comprising a first liquid having a density lower than 1.00 g/cm3 and a second liquid having a density higher than 1.00 g/cm3 which are immiscible with water and, at body temperature, one miscible with the other, for sequential use in the surgical treatment of tears and/or detachments of the retina, and a method for the treatment of tears and/or detachments of the retina using such liquids comprising the steps of injecting first the first liquid, or, respectively, the second liquid, into the vitreous cavity and maintaining it within the vitreous cavity for a determined period of time, thereafter injecting the second liquid, or respectively, the first liquid, into the vitreous cavity to mix with the other liquid and create with the latter a homogeneous solution having a density that is higher or lower than 1.00 g/cm3 respectively, if the first injected liquid had a density that was lower or higher than 1.00 g/cm3.

Abstract: Device for injecting into an eyeball a sterile liquid selected from amongst perfluorocarbons, comprising a tubular container body (3) having a first dispensing end (5) and a second end (6), and an adapter (4) for connecting a thrust fluid feed tube (6) to the second end (6). A first stopper (17) is inserted into the container body (3) in a sealed fashion and sterile liquid (2) is fed between the first stopper (17) and the first end (5). The adapter (4) consists of first and second connecting means (21), (22) to attach the adapter (4) to a feed tube (20) and to the second end (6), as well as first and second seal means (23), (24) to guarantee the fluid seal between the adapter (4) and the feed tube (20) and the container body (3). A duct (25) for the passage of a thrust fluid extends through the adapter (4) from the feed tube (20) to the container body (3).
