Definitions

  • IOLs are generally made of silicone, soft acrylics and hydro gels. These soft IOL’s rolled or folded and inserted through a smaller incision.
  • the device used for the folding of lens and delivers in the eyes is an injector cartridge. This IOL is usually pushed into the capsular bag by a soft tipped plunger, which also has a soft silicone pusher for its soft delivery of IOL.
  • patent EP1845899 discloses an injector comprising an injector nozzle which is pivotally attached to an injector body and pivotally movable with respect thereto between an IOL loading position and an IOL injection position.
  • the IOL is preloaded into a separate shuttle component of the injector device and placed in a vial storage solution during manufacture.
  • shuttle component is attached to the injector nozzle and the injector nozzle is pivoted on the injector body to the insertion position whereupon the injector device is ready for injecting the IOL into the eye.
  • U.S. Patent Application Publication No. 2007/060925 discloses an injector device having a proximal and distal sections packaged separately and then assembled together at the time of surgery. IOL is preloaded in the distal section of the device which is stored and packaged either in a dry package or submersed in a sterile storage solution.
  • a disposable, intraocular lens delivery device comprising an injector body, a plunger adapted to reciprocate within the injector body, said plunger comprising a removable locking mechanism which holds the piston from moving down during transport and storage, a retaining spring for reciprocating action during injection of lens, and a soft pusher or bung for pushing the lens through the cartridge into the eye.
  • the device further comprises a cartridge having located in the slot or housing of the injector body, its interior adapted for holding an intraocular lens and having a cave communicating with the distal end of the nozzle interior, adapted to cause the intraocular lens to fold when pushed forwardly from the nozzle interior by said plunger, the nozzle portion having a front cap / lid to cover the mouth of the injector body.
  • the device further comprises a hinged stop means with a lens stopper/lock associated with said lid adapted for preventing movement of the intraocular lens from said bore of the cartridge prior to use, during shipment and storage; and a port in the lens stopper for injection visco-elastic material and for sterilization.
  • This sophisticated delivery system invention prevents risk during delivery of IOL into the capsular bag and also prevents damage of lens during shipping or any improper handling or risk of infections before implanted.
  • the front haptic auto folder helps for the safer delivery of IOL into the capsular bag, on folding front haptic.
  • the device further comprises a cartridge having located in the slot or housing of the injector body, its interior adapted for holding an intraocular lens and having a cave communicating with the distal end of the nozzle interior by said plunger.
  • the device further comprises a cannular opening which is used for injecting BSS water or viscous-elastic material as well as an opening for sterilization.
  • a front haptic folder comprises a hinge property which is automatically folds the front haptic of the lens and released during delivery of the IOL safely into the capsular bag.
  • the cartridge further defines a tip adapted to deliver the IOL safely inside the capsular bag.

  • the device further comprises a cartridge (7) having located in the slot or housing of the injector body (5), its interior adapted for holding an intraocular lens (6) and having a cave communicating with the distal end of the nozzle interior by said plunger (1).
  • the device further comprises a cannular opening which is used for injecting BSS water or viscous-elastic material as well as an opening for sterilization.
  • the front haptic folder with hinge property which is automatically folds the front haptic of the lens and released during delivery of the IOL safely into the capsular bag.
  • the cartridge further defines a tip (11) adapted to deliver the IOL safely inside the capsular bag.
  • This present disposable preloaded delivery system consists of a plunger, injector body and a cartridge with front haptic auto folder.
  • the device of the present invention comprises an injector body (5) and a plunger (1); the said plunger and the injector body comprises a locking mechanism (4) that helps to prevent the plunger from moving during the shipment and storage.
  • the front haptic folder (9) automatically folds the front haptic during delivery and further coupled to a cartridge via a hinged portion (8).
  • the injector body (5) is made up of a disposable polymer material with a unique handle designed to rest the fingers of the forehand for easy handling.
  • the lens (6) made up of polymer material, which will be preloaded in the cartridge that will be housed in the injector body (5).
  • the cartridge (7) is specially designed for easy delivery of the lens into the eye without damage or deformation of the lens during delivery.
  • the inside of the cartridge contains a platform which helps to hold the lens stationary.
  • the cartridge has an elongated nozzle tube or tip with a bore, the bore communicating with the lens holding platform. The bottom of the bore is curved, which causes the edges of the lens rest during pre loaded condition so that the lens will not be damaged.
  • the cartridge is specially designed with Front Haptic Auto Folder (9) which folds the front haptic of the IOL (6) while injecting and delivers smoothly into the capsular bag.
  • the Front Haptic Auto folder has hinge property (8) to easily release the IOL during implantation. Since the injector system contains preloaded IOL (6) no other additional package required.
  • This system is packaged stored and delivered as a single unit without any additional devices like retainer and without the need for handling the lens at the user end and saves extra cost of additional package.
  • This system is also suitable for folding lenses made from a soft acrylic material as well as other materials such as silicones and hydrogels.

  • the cartridge may be designed and moulded in various shapes such as round, rectangle or square. Some of these features and designs are depicted in Fig.4.
  • the surgeon unpacks the Front Haptic Auto Folding Preloaded IOL Delivery device from sterile pack and cleans the IOL by BSS water through the cannula hole.
  • the lock in the plunger is released for the free soft movement guided by a ⁇ ’ ring.
  • the piston is injected slowly for the front haptic to be folded by auto haptic folder.
  • the folding of the front haptic of the IOL can be seen through by the surgeon.
  • On auto fold vise is applied again through cannula hole for its free movement and the front haptic auto folder which has hinge property is released.
  • the IOL is then pushed by a silicone pusher tip of the plunger and delivered into the capsular bag without any risk or damage to eyes.
