An apparatus for injecting an intraocular implant into the anterior chamber of a patient's eye, the apparatus comprising: (a) an elongate housing having a longitudinal axis and having a proximal end and a distal end; (b) an ejector button extending through an opening in the housing and moveable from a first position to a second position in a direction normal to the longitudinal axis of the housing; and (c) a needle having a proximal end and a distal beveled end, the needle extending longitudinally from the distal end of the housing, the needle having a lumen extending through the length of the needle such that the intraocular implant can be received within and translated through the lumen of the needle, the needle rotatable relative to the longitudinal axis of the housing in clockwise and counter-clockwise directions about its long axis; and (d) an implant holder having a proximal and a distal end and a lumen capable of receiving and holding the intraocular implant prior to activation of the apparatus, the implant holder located inside the housing, the apparatus being characterised by: the implant holder being capped at its distal end with a slit, cross-slit, or perforated membrane, the implant holder further being capable of movement, upon activation of the apparatus, from a first position to a second position within the housing along the longitudinal axis of the housing and in a direction toward the distal end of the apparatus to open the membrane, the lumen of the implant holder being aligned with the lumen of the needle such that, with the implant holder in the second position, the intraocular implant can slidably translate from the lumen of the implant holder into the lumen of the needle upon activation of the apparatus, and the ejector button being arranged such that depression of the ejector button from the first position to the second position in the direction normal to the longitudinal axis of the housing results in activation of the apparatus and ejection of the implant from the apparatus. (a) an elongate housing having a longitudinal axis and having a proximal end and a distal end; (b) an ejector button extending through an opening in the housing and moveable from a first position to a second position in a direction normal to the longitudinal axis of the housing; and (c) a needle having a proximal end and a distal beveled end, the needle extending longitudinally from the distal end of the housing, the needle having a lumen extending through the length of the needle such that the intraocular implant can be received within and translated through the lumen of the needle, the needle rotatable relative to the longitudinal axis of the housing in clockwise and counter-clockwise directions about its long axis; and the needle extending longitudinally from the distal end of the housing, the needle having a lumen extending through the length of the needle such that the intraocular implant can be received within and translated through the lumen of the needle, the needle rotatable relative to the longitudinal axis of the housing in clockwise and counter-clockwise directions about its long axis; and (d) an implant holder having a proximal and a distal end and a lumen capable of receiving and holding the intraocular implant prior to activation of the apparatus, the implant holder located inside the housing, the apparatus being characterised by: the implant holder being capped at its distal end with a slit, cross-slit, or perforated membrane, the implant holder further being capable of movement, upon activation of the apparatus, from a first position to a second position within the housing along the longitudinal axis of the housing and in a direction toward the distal end of the apparatus to open the membrane, the lumen of the implant holder being aligned with the lumen of the needle such that, with the implant holder in the second position, the intraocular implant can slidably translate from the lumen of the implant holder into the lumen of the needle upon activation of the apparatus, and the ejector button being arranged such that depression of the ejector button from the first position to the second position in the direction normal to the longitudinal axis of the housing results in activation of the apparatus and ejection of the implant from the apparatus. the implant holder being capped at its distal end with a slit, cross-slit, or perforated membrane, the implant holder further being capable of movement, upon activation of the apparatus, from a first position to a second position within the housing along the longitudinal axis of the housing and in a direction toward the distal end of the apparatus to open the membrane, the lumen of the implant holder being aligned with the lumen of the needle such that, with the implant holder in the second position, the intraocular implant can slidably translate from the lumen of the implant holder into the lumen of the needle upon activation of the apparatus, and the ejector button being arranged such that depression of the ejector button from the first position to the second position in the direction normal to the longitudinal axis of the housing results in activation of the apparatus and ejection of the implant from the apparatus.
