Light-guided ophthalmic radiation device

An device for holding a radioactive source in a treatment position for an eye, comprising:

• a solid wand made of light-transmissive material, the wand configured to direct light from a proximal end of the wand through its length and out of a series of at least four illumination ports at least partially circumscribing a holder, the illumination ports being positioned in a distributed manner radially surrounding the holder;
• the illumination ports providing conspicuous points of light during transpupillary viewing, each of the illumination ports includes a convex surface geometry that protrudes outward from a surface of the wand for providing a contact point with a sclera of the eye and configured to channel light substantially near a retina when the substantially light-transmissive wand is disposed in the treatment position for the eye, each illumination port minimizing light diffusion through the sclera while maximizing an intensity of light being emitted by coupled light transmittance that occurs when each illumination port contacts the sclera at a respective contact point with the sclera.
