Ophthalmic and otorhinolaryngological device materials containing an alkylphenol ethoxylate

An ophthalmic or otorhinolaryngological device selected from the group consisting of intraocular lenses;

• contact lenses;
• keratoprostheses;
• corneal inlays or rings;
• otological ventilation tubes;
• and nasal implants, wherein the device comprises a copolymeric ophthalmic or otorhinolaryngological device material formed by polymerizing a composition comprising
• a) 75 to 97% (w/w) of a monofunctional acrylate or methacrylate monomer of formula [1]:
• wherein
• B═O(CH2)n, NH(CH2)n, or NCH3(CH2)n;
• R1═H, CH3, CH2CH3, or CH2OH;
• n=0-12;
• A=C6H5 or O(CH2)mC6H5, where the C6H5 group is optionally substituted with —(CH2)nH, —O(CH2)H, —CH(CH3)2, —C6H5, —OC6H5, —CH2C6H5, F, Cl, Br, or I;
• and
• m=0-22;
• b) a difunctional acrylate or methacrylate cross-linking monomer of formula [2]:
• wherein
• R2, R3 independently=H, CH3, CH2CH3, or CH2OH;
• W, W′ independently=O(CH2)d, NH(CH2)d, NCH3(CH2)d, O(CH2)dC6H4, O(CH2CH2O)dCH2, O(CH2CH2CH2O)dCH2, O(CH2CH2CH2CH2O)dCH2, or nothing;
• J=(CH2)a, O(CH2CH2O)b, O, or nothing, provided that if W and W′=nothing, then J≠nothing;
• d=0-12;
• a=1-12;
• and
• b=1-24;
• and
• c) 3% (w/w) of an alkylphenol ethoxylate monomer of formula [3]:
• wherein:
• T=C8H17 or C9H19;
• e=40;
• or
• R4=H, CH3 and CH2CH3
• provided that the device material has a glass transition temperature not greater than 25° C.
