Abstract
An ophthalmological implant including a layer of pharmaceutical agent and an overlying layer of a bioerodible material, a biodegradable material a bioavailable material or a mixture thereof.
Claims20
1) An ophthalmological implant comprising:
- a. a filament configured for insertion into an eye;
- b. a first layer including a pharmaceutical agent;
- c. a second layer overlying the first layer and including a material selected from a bioerodible material, a biodegradable material, a bioavailable material or a mixture thereof.
2) An endocapsular tension ring comprising:
- a. a filament configured for insertion into an eye as an endocapsular tension ring;
- b. a first layer including a pharmaceutical agent;
- c. a second layer of variable thickness overlying the first layer and including a material selected from a bioerodible material, a biodegradable material a bioavailable material or a mixture thereof, the second layer being dimensioned for prolonged release of the pharmaceutical agent from the ring as the second layer degrades.
3) A method for making an endocapsular tension ring comprising the steps of:
- a. providing a filament configured for insertion into an eye as an endocapsular tension ring;
- b. attaching a first layer including a pharmaceutical agent to the filament;
- c. attaching a second layer of variable thickness over the first layer, the second layer including a material selected from a bioerodible material, a biodegradable material a bioavailable material or a mixture thereof, and the second layer being dimensioned for prolonged release of the pharmaceutical agent from the filament as the second layer degrades.
