The lens was returned adhered to/pressed between two plastic cups.Solution was dried on the lens.The lens was cleaned with lphse, for further evaluation.The optic has a large deep crack in the central optic zone of the lens.Other than the damage, the lens appears clear.Power and resolution testing could not be conducted, due to the extensive optic damage.Qualified associated products were indicated.The product investigation could not identify, a root cause for the reported complaint.Power and resolution testing could not be conducted, due to the extensive optic damage.The power and resolution of each lens is 100% evaluated, during the manufacturing process to determine acceptability per model and diopter.Information was provided in the file, that the multifocal toric 19.5 diopter (3.75cyl), add power +2.2 & 3.2 lens model was replaced with a monofocal toric (3.75cyl), 19.0 diopter lens model.Due to the exchange of a multifocal lens to a monofocal lens, this may suggest, that the replacement lens model was an improved choice for the patient's vision needs.No additional information has been provided at this time.The manufacturer internal reference number is: (b)(4).
