ABSTRACT:
The illuminated iris retractor probe system is a medical device for use in ophthalmic surgery, particularly anterior segment and posterior segment surgery where visualization of ocular structures is required. The device utilizes a handpiece to support a 23-gauge sheathed fiber optic element that transmits the illumination. The 23-gauge dimension of the sheathed fiber optic element allows it to be inserted through self-sealing incisions of 1.5-2.0 mm in size in the peripheral cornea, thereby allowing the incision to be self-sealing and thus avoiding the operative intervention and postoperative complications of sutures. The tip of the illuminated iris retractor probe has a backward bend or hook whose peripheral end is flush with the illumination end of a fiber optic element which is surrounded by a metal sheath. The specific angle of the hook and its location allows the probe to retract the iris during anterior segment procedures. This allows illumination of the peripheral vitreous to permit a more thorough vitrectomy in the anterior segment. The tip is designed to permit retraction of the iris without damaging the iris. The fiber optic element is attached to a light source connector which allows a tight connection to a halogen fiber optic light source.
