Abstract: A device for separating tissue in an eye includes a body configured to be positioned on the eye surface. The body receives air from one or more air supplies. The body includes one or more air supply channels. The separation device includes a plurality of needles extending from the body. Each needle includes a proximal opening, a distal opening, and a passageway extending between the proximal and distal openings. The proximal openings of the needles are coupled to the one or more air supply channels. The distal openings of the needles are spaced from the body to be positioned in eye tissue. The one or more air supply channels direct the air from the one or more air supplies into the proximal openings, through the passageways, and out the distal openings of the needles and into the eye tissue. The air applies a pressure to separate the eye tissue.

Abstract: A device for manipulating an implant includes a handle coupled to a guide extending from the handle to a distal end. The device includes an engagement mechanism disposed at the distal end of the guide and configured to engage an implant. The device includes a first actuator disposed on the handle and coupled to the engagement mechanism. The first actuator causes the engagement mechanism to engage the implant. The device includes an air chamber disposed in an interior chamber of the handle and configured to hold air. The device includes a lumen coupled to the air chamber and extending along the guide to the distal end. The lumen includes an air channel extending through the lumen. The device includes a second actuator disposed on the handle. The second actuator causes the air chamber to deliver the air, via the air channel, to the distal end.
