Abstract: An intraocular lens injection device comprises a tubular housing with a plunger longitudinally disposed within the tubular housing. An electric drive system longitudinally translates the plunger so that its tip engages an insertion cartridge to fold and displace an intraocular lens disposed within and to inject the folded lens into the lens capsule of an eye. A control circuit is configured to start translation of the plunger, responsive to user input, to detect at least one fault condition based on a counter-electromotive force produced by the electric motor, and to stop translation of the plunger assembly responsive to the detected fault condition, which may comprise excessive resistance to forward or rearward translation of the plunger or insufficient resistance to forward translation of the plunger.

Abstract: An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.

In the open position, pulses from the engine move the member to the closed position before pulses from the pulse engine can flow through the flow path, thereby preventing flow through the flow path.

Abstract: A plunger for an IOL injector device includes a shaft with a distal tip and a compressible sleeve positioned about the shaft with the tip extending forwardly of the sleeve.

Abstract: This invention is in the area of medical devices, in particular in the area of medical devices for drug delivery, more in particular for controlled release of drugs to the eye. Delivery of drugs to the anterior side of the eye is routinely done with eye drops, but this method results in low bioavailability and low patient compliance.

One of such devices, called the OphthaCoil, consists of a thin metallic wire, which is coiled and carries a drug-loaded adherent hydrogel coating on its surface. Surprisingly it has now been found that the drug loading capacity can be dramatically increased by filling the lumen of the coil with micro-particles such as microspheres that contain the drug of choice.
