14. Chronic uveitis 15. Diabetic retinopathy 16. Clinically significant macular/RPE changes Studies have shown that color vision discrimination is not adversely affected in individuals with the AcrySof® Natural IOL and normal color vision. The effect on vision of the AcrySof® Natural IOL in subjects with hereditary color vision defects and acquired color vision defects secondary to ocular disease (e.g., glaucoma, diabetic retinopathy, chronic uveitis, and other retinal or optic nerve diseases) has not been studied. WARNINGS 1. As with any surgical procedure, there is risk involved....

After opening the cardboard storage container, verify lens case information (e.g., model, power, and serial number) is consistent with information on outer package labeling. To remove the lens, open the pouch and transfer the case to a sterile environment. Carefully open the case to expose the lens. When removing the lens from the case, DO NOT grasp the optical area with forceps. Prior to the actual folding process, the lens should be handled by the haptic portion only. Rinse the lens thoroughly using sterile intraocular irrigating solution such as BSS® or BSS PLUS®. DO NOT rinse the lens...

AcrySof® Natural SINGLE-PIECE LENS Model SB30AL VISUAL ACUITY A summary of visual acuity achieved at a minimum of one year postoperatively among subjects who did not have preoperative ocular pathology, abnormal corneas, or macular degeneration at any time (Best Case) is presented in Table 2a, and visual acuity achieved by overall subject population is shown in Table 3a. Control data are found for the same data sets in Tables 2b and 3b, respectively. There was no statistically significant difference in visual acuity between Model SB30AL and the control lens, Model SA30AL, in either the best...
