The lens was returned positioned incorrectly in the lens case inside the opened carton.Dried solution was observed on the lens.One haptic has a line of parallel cracks on the anterior and posterior surface of the gusset area, similar in appearance to the shape of an instrument used to grasp or load a lens.The optic anterior surface was deeply scraped in a linear appearance from the anterior edge near the damaged haptic.The line of damage travelled from the edge, through the optic center, and toward the opposite side of the lens.The line of damage also included cracked areas, gouges and the end of the damage showed rounded small cracks, similar in appearance to damage from a metal instrument.The associated unknown cartridge model was not provided for an evaluation.Information was provided by the customer that a company handpiece was used.The associated cartridge and associated viscoelastic information were not provided.It is unknown if a qualified products was used with the lens.The reported lens damage was observed.All lenses are 100% inspected for cosmetic attributes and the damage exhibited by the returned complaint sample would not have met company 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.The linear damage included one haptic (both anterior and posterior surfaces, parallel) and the nearby anterior optic edge.The damage travelled across the optic center and ended toward the opposite side of the lens on the anterior optic surface.The damage was linear and excessive, with a similar appearance of damage created by a metal instrument used to load the lens into a cartridge.The associated cartridge and associated viscoelastic products are unknown.The instructions for use (ifu) instructs that an 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.Company recommends using the qualified company iol delivery system or any other company qualified combination.The manufacturer internal reference number is: (b)(4).
