The customer reported that there was a cataract extraction was performed on (b)(6) 2023, followed by implant of the lens as scheduled.After the implant of the lens, the surgeon was given a 3ml syringe filled with 3ml of bss (balanced salt solution) with a hydrodissection needle attached.The surgeon inserted the needle to the incision and it was then noted that the fluid came out of the eye quickly and the syringe was visualized by an associate to be in the surgeon's hand without the needle attached to the syringe, but was still located in the incision.The surgeon then viewed the needle through the microscope and removed it.The surgeon informed the surgical team that the lens would need to be removed and a vitrectomy would need to be performed.The patient suffered a complication due to the cannula shooting off into the eye while hydrating paracentesis at the end of the case.The cannula damaged capsule and zonules, causing iol(intraocular lens)/bag complex to dislocate.The iol implant was cut out of the eye and an anterior vitrectomy was performed.The patient was left aphakic.The initial investigation following this event determined that the event was due to user error.However on (b)(6) 2023, the physician suggested that the event may have been caused by an equipment malfunction.Per additional information received, the needle and the hub detached together from the syringe.The cardinal needle was removed from the cardinal syringe.The physician/health professional replaced the cardinal needle with an alton hydrodissection needle and used it combination with the cardinal syringe.This was the needle that was used multiple times throughout the procedure.
