Technical Field

The present invention relates to compositions for ophthalmic products, to the corresponding copolymers and to the preparation thereof, to their use for the production of ophthalmic lenses or ophthalmic implants, and to these products.

Prior Art

Cataracts represent clouding of the lens of the eye, which results in slow, painless loss of vision, particularly when clouding begins in the central region of the lens. Those affected feel their environment "as if they were fog-through". In most cases, a clouded lens can be surgically replaced by a synthetic lens implant, the so-called intraocular lens (IOL).

Various intraocular lenses are known. Such as an intraocular lens consisting of a central optical lens and peripheral attachment haptics that secure the optical lens in the eye. The contacts can have various shapes, for example, C-ring contacts or plate contacts. Depending on the material, the lens can be classified into a hard, non-foldable IOL and a soft, foldable IOL. The hard lens consists of polymethyl methacrylate. Foldable lenses consist of acrylates, silicones, or hydrogels. The advantage of a foldable lens is mainly that a smaller incision is required for implantation. One new form of intraocular lens is the accommodating optic lens (LAL). In the case of LAL, the optical power can be adjusted after operation by irradiating light of a suitable wavelength (e.g. UV light).

The lens (phakic) intraocular lens (PIOL) is an artificial lens that is implanted in the eye in addition to the natural lens. A phakic intraocular lens may be implanted as part of correcting the visual impairment. The PIOL consists of a central optical lens and peripheral attachment haptics that secure the optical lens in the eye. A distinction is made between the anterior and posterior chamber lenses depending on the position of the PIOL in the eye. An anterior chamber lens is implanted between the cornea and the iris, and a posterior chamber lens is implanted between the iris and the lens. The anterior chamber lens is composed of hard polymethylmethacrylate or soft materials such as silicone or acrylic. The posterior chamber lens is typically made of a soft material.

The adjustable optical lens may be composed of, for example, a silicone containing free radicals having photochemical activity in the UV range. If LAL is irradiated with ultraviolet rays, the polymer changes its structure. The first dimmable lenses were developed by the American ophthalmologists Daniel Schwarz and Robert Grubbs (Daniel M.Schwartz et al, Light-adjustable lenses: reduction of in vitro nomograms; in Transactions of the American opthalmological Society, Vol.102, December 2004,67-74.) in 1999.

The development of materials suitable for IOLs is rapid. For example, US 8,247,511 describes the production of an intraocular lens wherein a rigid copolymer is made from a first monomer selected from the group consisting of Ethylene Glycol Phenyl Ether Acrylate (EGPEA) and polyethylene glycol phenyl ether acrylate [ (poly-EG) PEA ], a second monomer selected from unsubstituted or substituted styrenes and a third monomer containing ethylenic unsaturation which will form a hydrogel as a homopolymer, to form a rigid intraocular lens which is then converted to a foldable intraocular lens by hydration wherein the refractive index of the lens is about 1.50.

Artificial intraocular lenses formed from polymeric materials containing photochemically activatable groups, which allow photoinduced modification of the optical properties of the artificial intraocular lens, are known, for example, from EP 1926454.

Photochemical reactions of polymethacrylates containing 3-phenylcoumarins are described, for example, in M.Schraub et al, European Polymer Journal 51(2014) 21-27.

WO 2017/032442, WO 2017/032444 and WO 2017/032443 describe materials for the production of medical devices, preferably ophthalmic products, particularly preferably for the production of intraocular lenses. These materials can preferably be used as photoactive monomers in suitable polymers or copolymers for the preparation of products.

Hydrophobic, soft acrylate polymers and silicone polymers known for use in the production of intraocular lenses exhibit glistenings. In the first mentioned polymers, the tendency to sparkle is more pronounced. According to a.miyata and s.yaguchi, JCataract regract Surg 2004; 30: 1768-1772, flashing is a phase separation phenomenon that occurs when the temperature changes once the polymer is in an aqueous environment, as in the human eye. The water content of the polymer increases with temperature. In the case of a temperature drop, the water absorption capacity of the polymer decreases, causing phase separation. The polymer phase here has a different refractive index than the aqueous phase, thereby causing the aqueous phase to be perceived as sparkling in the form of vacuoles. The degree of flashing depends critically on the temperature dependence of the water content of the polymer. The greater the temperature dependence, the more severe the patient's glint-induced visual loss may be.

The water content in the polymer can be increased by adding a hydrophilic component during the polymerization. The hydrophilic component is a monomer whose uncrosslinked homopolymer is water-soluble or swellable in water. The crosslinked copolymer comprising a hydrophilic component may be, for example, a hydrogel. Such hydrogels form another class of ophthalmic materials, hydrophilic acrylate polymers. From e.g. US 8,247,511 and Bozukova D et al, mat.sci.eng.2010,69:63-83 are known that they are rigid in the dry state and soften after swelling in water.

The water content of this polymer is greater than 10% by weight. If the water content of such swollen polymers is more than 10% by weight, the term hydrophilic polymer can be used.

In contrast to hydrophobic acrylate polymers, hydrogels do not exhibit glitter, but in which calcification can occur, as described by Trivedi et al, Eye 2002,16: 217-241. Calcification refers to calcium compounds that deposit primarily on the lens surface and obscure vision.

Thus, there are two undesirable phenomena, namely flashing and calcification, which occur in the case of polymeric materials with too low or too high hydrophilicity, respectively.

It is an object of the present invention to provide suitable polymeric materials comprising specific photoactive polymeric monomers which are soft and shapeable at ambient temperatures of 16 ℃ to 18 ℃ and which exhibit little or no sparkle and at the same time are sufficiently hydrophobic without calcification, and corresponding compositions suitable for the preparation of such materials. The polymer material should also be transparent and change its refractive index when exposed to light of a selected wavelength λ (e.g. using a UV light source of the corresponding wavelength λ) or when using a laser with a sufficiently high pulse frequency (which emits light at a wavelength of 2 λ or even n λ, where n is a natural number). Furthermore, in an aqueous environment at 35 ℃, the polymeric material and the corresponding ophthalmic lens comprising the polymeric material should have a development time of less than 60 seconds, preferably 10 to 40 seconds, particularly preferably 15 to 25 seconds. The development time of known materials is described, for example, in "the ophthalmologist,2017, Issue # 1217".

Specific photoactive monomers are known, for example, from WO 2017/032442.

This object is achieved accordingly by the independent and dependent claims of the present patent application.

Summary of The Invention

It has been found that a suitable choice of monomers in a composition comprising specific photoactive monomers leads to the preparation of a crosslinked transparent copolymer which changes the refractive index by exposure to light of the corresponding wavelength, is free or virtually free of glistenings, and remains soft without further hydration at ambient temperatures between 16 ℃ and 18 ℃ and can therefore be implanted in the eye, for example in the form of an intraocular lens, by means of a standard applicator according to the prior art. Furthermore, the polymeric material is transparent and changes its refractive index upon exposure to light of a corresponding wavelength λ (for example using a UV light source of a corresponding wavelength λ) or using a laser with a sufficiently high pulse frequency (which emits light at a wavelength of 2 λ or even n λ, where n is a natural number). Intraocular lenses produced from crosslinked clear copolymers have advantageous unfolding times.

The material preferably has no sparkle. The term "no or virtually no sparkle" means that the copolymer is always clear and has a vacuole number of less than 100 vacuoles/mm, according to the scintillation test described herein and in Clinical Ophthalmology,2013,7,1529-³Preferably less than 25 vacuoles/mm³Particularly preferably below 20 vacuoles/mm³And very particularly preferably below 10 vacuoles/mm³Or less than 5 vacuoles/mm³(ii) a These values correspond to the 0-order introduced by Akira Miyata. Miyata et al, Jpn JOphthalmol 2001,45, 564-569 describe a vacuole/mm of less than 50³Is 0 grade, 50 vacuoles/mm³Is a rating of 1, 100 vacuoles/mm³Of order 2Limit and 200 vacuoles/mm³Is a 3-level limit.

The present invention therefore relates firstly to a composition comprising specific photoactive monomers of formula (1) as described below, at least one hydrophilic monomer whose uncrosslinked homopolymer is water-soluble or swellable in water, a UV absorber and a crosslinker, wherein the molar ratio of the sum of all compounds of formula (1) to the sum of all hydrophilic monomers is 1: 0.51 to 1: 1.24.

furthermore, the invention relates to the use of the composition for the preparation of the corresponding copolymer or for the production of blanks for ophthalmic lenses or ophthalmic implants.

Furthermore, the present invention relates to the corresponding crosslinked copolymers, to a process for preparing copolymers of this type and to their use for the preparation of articles, preferably blanks for ophthalmic lenses, blanks for ophthalmic implants, ophthalmic lenses or ophthalmic implants.

Furthermore, the invention relates to a corresponding article and to a method for producing the article.

All compounds or components which can be used in the compositions are known and commercially available or can be synthesized by known methods, for example, as described in WO 2017/032442, pages 21 and 22 and pages 44 to 78 for the compounds of formula (1). The document WO 2017/032442 is incorporated herein by reference.

The compounds of formula (1) and preferred embodiments thereof as described below include all stereoisomers or racemic mixtures.

In general, a surface is classified into a hydrophilic surface and a hydrophobic surface according to its contact angle with water. The following conditions apply: 0 degree<Contact angle<90 degree hydrophilicity; contact angle>90 deg. hydrophobic. The contact angle here is a result of the surface structure and material (literature:R.；

h; tobias, a.; jenkins, A.See Appendix C.In surface design Applications in Bioscience and Nanotechnology; Wiley-VCH, Weinheim, Germany, 2009; page 471). Since the hydrophilic and hydrophobic partitioning is mainly related to the bulk properties of the polymer and its individual components, said partitioning by contact angle is not suitable.

For the classification of intraocular lenses into hydrophilic and hydrophobic lenses, Bozukova et al uses their water content as a classification criterion. If the water content is less than 10-20 wt%, it is a hydrophobic intraocular lens; if the water content is greater than 10-20% by weight, a hydrophilic intraocular lens is obtained (Bozukova D, Pagnoulle C, J E colour R, J E colour C, (2010) Polymers in modified ophthalmic implants-Historical background and surgical additives, Material Science and Engineering R69: 63-83). For the polymers prepared in the context of the present invention, the water absorption of the material is a more suitable criterion with regard to hydrophilicity and hydrophobicity in terms of their field of application. In order to separate the monomers into hydrophilic and hydrophobic monomers, the use of the partition described by Bozukova et al is useful in the context of the present invention and its application purposes: if a homopolymer is given by a monomer that is completely water-soluble or has a water absorption of more than 10% by weight, it exhibits hydrophilic properties and is classified as a hydrophilic monomer for the purposes of the present invention. Hydrophilicity is caused by functional groups in the monomer that can bind water molecules. This property can be confirmed by the presence of water that is not freezable in the swollen state. Herein, the non-freezable water is based on the fact that: the functional groups in the polymer themselves bind water and, therefore, the water is unable to form ice crystals regardless of temperature. Without this being affected, this type of polymer may also contain freezable water that forms ice crystals, but this is not used to differentiate between hydrophilic and hydrophobic monomers. Examples of functional groups capable of binding non-freezable water are, inter alia, hydroxyl, amino, ammonium, carboxyl, sulfone, sulfate, ether bridges or amide groups. Thus, the presence of such functional groups in the monomer is indicative of a hydrophilic monomer.

Thus, if the monomer meets one or more of the above-mentioned water solubility criteria for the resulting homopolymer, the resulting homopolymer has a water absorption of greater than 10 weight percent and/or non-freezable water is present in the resulting homopolymer, which for the purposes of the present invention is a "hydrophilic monomer". If the monomer does not meet any of the above criteria, then for the purposes of the present invention, this is referred to as a "non-hydrophilic monomer".

If the composition according to the invention as described above or preferably described is polymerized, a crosslinked copolymer is formed which is soft at ambient temperatures of from 16 ℃ to 20 ℃ and has all the advantages as described above. They exhibit in particular no or virtually no sparkle. The term "no or virtually no sparkle" has the meaning as described above. The copolymer has a glass transition temperature (Tg) of 15 ℃ or less and a refractive index of at least 1.5, preferably at least 1.52, wherein the inducible change in refractive power is preferably still at least 0.005(Δ n)_D＝0.005)。

The present invention therefore also relates to a crosslinked copolymer comprising a polymerized composition as described above or preferably described.

The invention therefore also relates to crosslinked copolymers consisting of polymerized compositions as described above or preferably described.

The reaction conditions for free-radical polymerization are sufficiently known to the person skilled in the art in polymer chemistry. Due to the specific feature that the compounds of formula (1) or preferred embodiments thereof as described above are generally hydrophobic, in particular due to the presence of hydrophilic monomers, the miscibility of the components of the composition according to the invention may be limited. However, the person skilled in the art is able to select the initiator carefully and, in the case of thermal treatment, the method with respect to temperature, so as to form a homogeneous copolymer. In the case of a particular miscibility gap, the polymerization temperature should be chosen so that it is not within the miscibility gap. One skilled in the art will be able to identify incompatibilities in the materials that may result in miscibility gaps. As mentioned above, he can irradiate the composition according to the invention, for example by means of a suitable light source, and record the UV/VIS spectrum at various temperatures. Suitable wavelengths are between 450nm and 750 nm. For example, if the transmittance is plotted against temperature for a wavelength of 450nm, the miscibility gap is determined if the increase in transmittance jumps. The jump in transmission can be explained by a sudden drop in the density of the mixture when separation occurs. With the aid of this type of experiment, the person skilled in the art is able to select a suitable temperature for the thermally induced free-radical polymerization.

The present invention therefore also relates to a process for the preparation of crosslinked copolymers as described above, characterized in that a composition according to the invention as described above comprising or consisting of the or the preferred components is provided and subsequently free-radical polymerized, wherein the polymerization temperature selected in the case of the use of a thermal free-radical initiator is not within the miscibility gap of the materials of the provided composition.

As mentioned above, the polymerization is preferably carried out in the absence of a solvent.

The properties of the copolymers according to the invention as starting materials for the production of ophthalmic products can be determined by standard methods, for example using refractometers with and without radiation. The sparkle and water uptake was determined by incubating the sample for a period of time at a temperature, generating a multifocal image and calculating the vacuole on the image. The number of vacuoles is expressed as normalized to volume. The water absorption can be determined, for example, by the difference in mass before and after incubation in water. Techniques for determining material properties of polymers are known in the art and are not limited in any way. The method for characterizing the crosslinked copolymer according to the invention is described in more detail in the experimental section, but it should not be considered limiting.

The invention also relates equally to the use of a composition as described or preferably described above or of a crosslinked copolymer obtained by polymerization of a composition as described or preferably described above for the production of a blank for an ophthalmic product, preferably for an ophthalmic lens or an ophthalmic implant, particularly preferably for an intraocular lens.

The term "blank" may also be used synonymously with the term "semi-finished product" and describes a product in basic form produced from one or more raw materials to such an extent that the number of work steps required for manufacturing the final product is significantly reduced. Typically, the billet is pre-sized, geometrically specified, solid, and meets certain standards and certification practices. The term "semi-finished product" known from the metal industry, resulting from "semi-finished product manufacture", encompasses not only products made of metal or metal alloys, but also products made of plastics, and correspondingly also applies to the manufacture of medical products, including also ophthalmic products.

The invention therefore also relates to an article comprising a copolymer according to the invention or a polymerized composition according to the invention as described or preferred above. Thus, the article has the same advantages as described for the copolymer of the invention. The above statements apply accordingly.

The article is not subject to any restrictions and is preferably a blank or a finished ophthalmic product, preferably an ophthalmic lens or an ophthalmic implant, particularly preferably an intraocular lens or a phakic intraocular lens.

The invention therefore also relates to an article as described above, selected from a blank for an ophthalmic lens or an ophthalmic implant, an ophthalmic implant or an ophthalmic lens.

As mentioned above, the copolymer according to the invention or the polymerized composition according to the invention can be used without limitation for any type of ophthalmic lens, preferably intraocular lenses or lens optics, suitable for both haptics and central optical lenses. The material according to the invention can also be combined with other materials known for the manufacture of ophthalmic lenses. This would be the case, for example, if the haptics are intended to be composed of a different plastic than the central optical lens. Those skilled in the art of intraocular lens production are familiar with the necessary process steps for producing blanks and finished products.

The free-radical polymerization of the compositions according to the invention as described above or preferably described can be carried out, for example, in a polymerization mold. A variety of materials, molds and techniques are known in this regard. The experimental section describes a corresponding example.

The invention therefore also relates to a process for the production of the articles as described or preferably, characterized in that a composition according to the invention as described above is provided, the polymerization is carried out and the articles are simultaneously or subsequently shaped. The article may be produced, for example, by molding into a blank that is further converted into a finished product, such as an ophthalmic lens, as described above. Further manufacturing steps by means of cutting methods are sufficiently known to the person skilled in the art.

It is assumed that a person skilled in the art will be able to utilise the above description in its broadest scope, even without further comments. The preferred embodiments are therefore to be considered as merely illustrative disclosures which are in no way limiting.

All temperatures above and below are expressed in degrees Celsius.
