A non-healthcare professional reported that during intraocular lens (iol) implantation surgery, the haptic was not folded properly and lens advanced with difficulty.The lens was examined under a microscope and was seen to be damaged.Additional information has been received stating that there was no patient contact, the device tip didn't come in contact with the patient and the procedure was completed on the same day.

Additional information was provided in d.9., h.3., h.6., h.11.The product was returned for analysis.The device was returned loose in the product carton.The lock-out assembly has been removed.Viscoelastic is observed in the device.The plunger has been advanced at the wound guard and is advanced slightly under the iol (intraocular lens).The iol is advanced to the wound guard and is damaged.We are unable to determine the root cause for the reported complaint.The reporter stated: "the haptic was not folded properly", misfolding of the haptic event can occur: if the lens has become misaligned in the lens bay during the manufacturing process.Due to the use of a non-qualified viscoelastic.Material properties of non-qualified ovds (ophthalmic viscosurgical device) may contribute to underfill, overfill, misfolding of the haptics, or other inconsistent folding outcomes.If inadequate viscoelastic is placed in the device this will cause inadequate coverage of the lens fold path which may cause the lens to advance incorrectly.If the operating room temperature is too high (more than 23 degree celsius / 73-degree fahrenheit) lens folding consistency is negatively affected, the lens is more adherent and this may inhibit lens advancement.Any of the above listed causes alone, or in combination, may create the reported event.Based on the results from the product history record, the products met release criteria.The manufacturer internal reference number is: (b)(4).
