A non-healthcare professional reported that during an intraocular lens (iol) implant procedure, after the lens was inserted, the doctor saw bubbles inside the lens material and cut out the lens during the same procedure.The procedure was completed the same day using a replacement lens, which went fine.Additional information has been requested.

Additional information was provided in d.9., h.3., h.6.And h.11.The lens was returned positioned incorrectly inside the lens case in the opened peel pouch inside the lens carton.Solution was dried on the lens.The optic was cut into two pieces, typical of an insertion and removal.Both haptics were bent in the distal area.The optic edge has a large broken area with lines of cracked damage observed.The lens was cleaned with klrp to further evaluate.The bent haptics relaxed to their original positions.The posterior of the optic was scraped and cracked.The anterior optic surface has a line of cracked damage between the optic center and the optic edge.The visual appearance of the lines of damage may have been interpreted as bubbles inside the lens material.There were no bubbles observed.Both optic portions have lines of cracked damaged on the anterior and directly on the posterior surface in the shape of an instrument used to grasp the lens.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.A qualified cartridge and viscoelastic were used.An unspecified model of company handpiece was used.The root cause cannot be determined for the reported complaint of bubbles in the lens material.There were no bubbles observed in the lens material.Scraped and cracked optic damage were observed which may have been interpreted as the reported complaint.The lens was cut into two pieces, typical of an insertion and removal.It is unknown if a qualified handpiece was used.The instructions for use (ifu) instructs: company foldable iols are qualified for use with a company qualified delivery system (handpiece and cartridge) and ophthalmic viscosurgical device (ovd) combination.The ifu instructs that a company qualified delivery system and viscoelastic combination should be used.The use of an unqualified combination may cause damage to the lens and potential complications during the implantation process.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.The instructions for use (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 company.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 intraocular lens (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 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).
