The lens was returned in the loading area of a qualified company cartridge.An insufficient amount of viscoelastic was observed in the cartridge.One haptic was broken in the gusset area (not returned).The cartridge does have slight evidence that it was placed in a handpiece.No tip damage observed.Product history records were reviewed and the documentation indicated the product met release criteria.A qualified cartridge and handpiece were used.A non-qualified viscoelastic was indicated.Based on the provided information, the root cause is most likely related to a failure to follow the ifu.A non-qualified viscoelastic was used.The ifu instructs: company foldable iols are qualified for use with an company qualified delivery system (handpiece and cartridge) and ophthalmic viscosurgical device (ovd) combination.The 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.In addition, an inadequate amount of viscoelastic was observed in the cartridge.The ifu also instructs to completely fill the cartridge with ovd (diagram provided) 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 delivery issues or damage.The cartridge shows evidence it was placed into a handpiece, but not fully seated.The ifu instructs the user to insert the cartridge into the handpiece and fully slide the cartridge forward into the handpiece locking slots.The cartridge did not appear to have been fully seated in the handpiece.This could have caused the lens to deploy incorrectly or the plunger to be misaligned during advancement which could result in delivery issues and or product damage.The manufacturer internal reference number is: (b)(4).
