The lens was returned positioned incorrectly in the lens case.Blood and solution was dried on the lens.One haptic was broken in the haptic insertion area and the distal area (returned).The optic was cut from edge towards center, typical o insertion and removal.Product history records were reviewed and documentation indicated the product met release criteria.A qualified cartridge and handpiece were indicated.The associated viscoelastic was not provided.It is unknown if a qualified product was used.The reported broken haptic was observed.All lenses are 100 percent inspected for cosmetic attributes and the damage exhibited by the returned complaint sample would not have met company¿s release criteria.Based on our observation, and the review of manufacturing records, it can be reasonably concluded that the damage is not manufacturing related.Due to the presence of surgical solution and the condition of the returned sample, the damage is most likely related to customer handling.Haptic manufacturing is a validated process with multiple inspections to verify the quality of the produced haptic material.These inspections include a verification of the dimensional accuracy, tensile strength, flexibility and cosmetic appearance.The inspections ensure that the material meets all required specifications before it is allocated for use.Not enough information was provided to determine if a qualified viscoelastic was used.The instructions for use (ifu) instructs that an company qualified delivery system and viscoelastic combination should be used.Company foldable iols are qualified for use with an company qualified delivery system (handpiece and cartridge) and ophthalmic viscosurgical device (ovd) combination.The use of an unqualified combination may cause damage to the lens and potential complications during the implantation process.In addition, the ifu has specific lens loading instructions for multipiece lenses.The ifu instructs: use holding forceps to grasp the lens by the optic edge and gently place the lens anterior side up into the back of the ovd-filled cartridge (diagram provided).The lens should be inserted until it is centered with or slightly past the outline etched into the top of the cartridge.Lenses with a 6.5 mm optic diameter may need to be pre-folded for easy entry into the back of the cartridge.Lens may be pre-folded by gently applying pressure to the edge of the lens while holding the central optic with forceps as shown.The trailing haptic will extend from the proximal end of the cartridge.Position the trailing haptic to the left of the haptic post as shown in the detailed view.This will allow the plunger to go past the haptic during the initial advancement of the plunger into the cartridge.Verify the lens is positioned on the bottom surface of the cartridge.The haptic should be maintained to the left of the post when the lens is loaded correctly.Accurate positioning of the lens will decrease the potential for optic and haptic damage.No further information has been provided at this time.The file will be reopened and updated if new information is received.The manufacturer internal reference number is: (b)(4).

A healthcare professional reported that, during intraocular lens implantation surgery, while the doctor was delivering the intraocular lens (iol) into the patient¿s eye, the haptic of the lens broken.Hence the lens was removed and replaced with another lens during the same surgery.There was no patient harm.
