Abstract
An intraocular device to assist a physician for injecting into an eyeball by aligning a device to aspects of the eyeball. The device may be adapted to control the depth of an injection needle and to align the correct placement of the needle.
Claims20
An intraocular injection device, comprising:
- (a) an elongated tubular member having an injector receiving end and a scleral end, with the scleral end further comprising an end flange disposed at the corneal end;
- (b) a guiding channel extending from an injector receiving end to the end flange, the guiding channel having a lower lumenal end and a lower lumenal end, the lower lumenal end further having a syringe stopper, the syringe stopper is adapted to control the depth of a needle penetration into an eyeball;
- (c) the end flange being disposed around three sides of the corneal end, the end flange also including a scleral surface disposed on one side of the end flange;
- (d) the scleral surface is curved to match the corneal or scleral surface of an eyeball, the surface further having a corneal edge that is adapted to align to a cornea of the eyeball;
- and
- (e) the end flange further including a needle exit, the needle exit having a needle exit corneal edge that is no less than 3 mm from the flange corneal edge.
