Apparatus (40) and methods for introducing a solid or semi solid intraocular drug containing implant (68) into the anterior chamber of an eye are described. The drug containing implant can be a rod shaped biodegradable implant that may provide for the extended release of the drug and may be effective for treating a medical condition of the eye. The apparatus is economically designed in the shape or style of a pen with tactile surfaces for easy gripping a needle rotation knob (52) to permit orientation of the needle (56) bevel in relation to the eye and a spring actuated mechanism for consistent deployment of the implant.
