Product catalog summary
Product Overview
AcrySof® Natural lenses are foldable acrylic lenses designed to replace the human crystalline lens in adults to correct aphakia. They filter blue light similarly to the natural lens, reducing transmittance significantly between 400 nm and 475 nm.
Specifications
These lenses are made from high refractive index soft acrylic, allowing them to be folded for insertion. They feature a biconvex optic with supporting haptics and are available in powers from +6.0 to +40.0 diopters.
Indications and Contraindications
The lenses are indicated for visual correction of aphakia post-cataract extraction and are intended for placement in the capsular bag. They are not suitable for patients with severe eye disease or glaucoma.
Warnings and Precautions
Potential complications include corneal damage, retinal detachment, and glaucoma. Long-term effects are not fully known, necessitating regular postoperative monitoring. They should not be used for clear lens exchange.
Clinical Studies
Studies have shown the safety and effectiveness of the AcrySof® Natural Lens Model SB30AL, with positive outcomes for patients followed for at least one year postoperatively.
Handling and Storage
Lenses should not be resterilized and must be stored below 45°C. Only sterile intraocular solutions should be used for rinsing, and proper surgical skill is required for implantation.
Patient Registration and Reporting
Patients must be registered with Alcon Laboratories for long-term follow-up, and adverse events should be reported for documentation.
Demographics and Study Population
The study involved two groups: SB30AL and control SA30AL. The SB30AL group was 70.6% female, predominantly Caucasian, with a mean age of 72.9 years.
Visual Acuity Outcomes
One year postoperatively, 79.8% of SB30AL patients achieved 20/20 or better visual acuity, similar to the control group.
Adverse Events
No significant differences in adverse events, including macular edema and lens dislocation, were observed between the groups.
Color Perception
Color perception tests showed no significant impact on color vision, with 98.2% of SB30AL patients passing.
Nd:YAG Rates
The incidence of Nd:YAG posterior capsulotomy was low and similar between the groups.
Product Information
Lenses are supplied sterile and must be opened aseptically. Expired lenses should be returned to Alcon Laboratories.
Returned Goods Policy
In the U.S., lenses can be exchanged but not credited. Returns require a Returned Goods Number and must be traceably shipped. Outside the U.S., local Alcon offices handle returns.
References and Symbols
The document includes references to previous studies and a list of symbols used in labeling.

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. Potential...

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 in...
