A non-healthcare professional reported that during an intraocular lens (iol) implant procedure, the surgeon stated he had loaded the lens into the injector, and the procedure was progressing smoothly without any issues.However, upon insertion into the eye, he noticed that one of the haptics was broken.As a result, the lens had to be removed from the patient¿s eye.Additional information was received as the patient was aphakic for two days until the replacement lens arrived.The patient is currently doing well.

Additional information provided in h.3., h.6.And h.11.A photo was provided of the lens inside the eye.The image (photo) was of a monitor screen and the person taking the photo can be seen to the right side of the screen.The yellow lens was shown partially inserted into the eye.The leading haptic, optic, and distal portion of the haptic was inside the eye.The trailing haptic extended outside the incision, showing the point of breaking at the distal area.The remainder of the trailing haptic distal area was inside the eye, on the anterior optic surface.A device history record review and a non-conformance review of the reported lot number was conducted.The deviation review did not reveal any potential contributing factors to the reported complaint and all corresponding production release specifications defined in the device master record were met.All of the associated products were qualified for this lens.Based on our observation of the attached photo, broken haptic damage was observed.It is difficult to make a final determination without evaluation of the physical sample.The root cause cannot be determined based on available information.The product was not returned.The ifu instructs: using holding forceps, grasp the lens by the optic edge and gently place the lens anterior side up into the back of the ovd-filled cartridge.The lens should be inserted until the optic is a little more than half-way inside the cartridge.Use the holding forceps to gently push down on the lens, verifying that the lens is on the bottom surface of the cartridge.Using holding forceps, take the trailing haptic, and gently fold the haptic onto the anterior side of the optic.Slowly grip or push the optic edge to position the lens as far into the cartridge as the forceps will permit, while ensuring the lens remains on the bottom surface of the cartridge and the trailing haptic remains on the optic.Failure to follow these steps may cause the lens to advance incorrectly causing delivery issues and/or damage.It is unknown if adequate viscoelastic was used in the cartridge.The ifu instructs to completely fill the cartridge with ovd immediately prior to loading and delivery of the lens.Do not attempt to load the lens without adequate ovd in the device.Not adequately filling the device with viscoelastic will result in inadequate coverage of lens and the lens fold path with ovd, which may result in damage.Important: the plunger should make initial contact with the cartridge at the ramp.In the event the plunger does not contact the cartridge at the ramp, do not use the handpiece and contact alcon.The handpiece ifu instructs: verify that the plunger tip is properly engaging the lens optic and that the lens moves forward at the same rate as the plunger while slowly advancing the plunger forward to avoid damaging the lens.When the threads on the knob make contact with the barrel, turn the knob clockwise approximately ½ turn to engage the threads and then stop.The iol will now be in the dwell position.Inspect to ensure the plunger is behind the optic.The ifu instructs: follow the section regarding directions for use for information on the maximum allowed time for the iol to stay in the folded condition.Failure to adhere to manufacturer¿s recommendations may result in iol damage.Ifu note: during lens loading and insertion, do not allow the company iol to remain in a folded condition within the selected iol delivery system for more than 3 minutes prior to completing insertion into the capsular bag.The manufacturer internal reference number is: (b)(4).
