MODEL SN6CWS

Product catalog summary
Product Overview
AcrySof® IQ lenses are designed for visual correction post-cataract surgery, filtering UV and blue light to mimic the natural lens. Made from high refractive index acrylic, they unfold after implantation.
Specifications
The lenses have a biconvex optic with haptics, made from acrylate/methacrylate copolymer, with a refractive index of 1.55, delivered via the AcrySert® C System.
Indications and Contraindications
Indicated for aphakia correction in adults post-cataract surgery. Not suitable for patients with severe eye conditions like glaucoma.
Warnings and Precautions
Risks include corneal damage and retinal detachment. Safety in patients with preexisting conditions is not established. Regular monitoring is advised.
Procedures
Use the AcrySert® C System at specified temperatures, inspect packaging, and follow detailed implantation steps to avoid damage.
Lens Power Calculation
Preoperative calculation is based on surgeon experience and intended placement, with references provided.
Storage and Handling
Do not resterilize or store above 45°C. Handle carefully; the delivery system is single-use only.
Contact Information
For lens power calculation details, contact Alcon Laboratories.
Lens Delivery Procedure
Emphasizes slow delivery to prevent damage, with correct positioning in the capsular bag. The device is single-use.
Patient Registration and Reporting
Post-implantation registration with Alcon is required for follow-up. Report adverse events to Alcon.
Clinical Studies
Two studies showed no significant difference in visual acuity between AcrySof® lenses and controls, but improved contrast sensitivity and reduced aberrations with the AcrySof® IQ lens.
Visual Acuity Results
Tables show similar visual acuity outcomes between AcrySof® and control lenses.
Adverse Events
Tables list adverse events with no significant differences between lens models.
Color Perception and Nd:YAG Rates
No significant differences in color perception; low Nd:YAG capsulotomy rates.
AcrySof® IQ Lens Study
Showed reduced aberrations and improved contrast sensitivity, especially under low light conditions.
Overview
Highlights improved visibility and safety for drivers using AcrySof® IQ lenses under challenging conditions.
Key Findings
  • Improved response time for city pedestrian detection and rural sign identification.
  • No clinically significant differences in detection times under glare when excluding certain patients.
Product Information
  • Lenses are dry, sterilized with ethylene oxide, and must be opened aseptically.
  • Expired lenses should be returned to Alcon.
Return Policy
In the U.S., lenses can be exchanged but not returned for credit. Returns require a Returned Goods Number.
References
Cites studies on ocular media transmission and driver perception-brake times.
Symbols Used
Includes symbols like IOL (Intraocular lens) and STERILE EO (Sterilized by ethylene oxide).

UV-light filtering, the AcrySof® IQ IOL reduces transmittance of blue light wavelengths from 62% at 400 nm to 23% at 475 nm (see Table 1). The optical portion consists of a high refractive index soft acrylic material. This material is capable of being folded prior to insertion. The lens gently unfolds to a full-size lens body following implantation. The lens has a biconvex optic with supporting haptics. The posterior aspheric surface of the AcrySof® IQ Model SN6CWS IOL is designed with negative spherical aberration to compensate for the positive spherical aberration of an average cornea. The...

The image quality of the Model SN6CWS was characterized by measuring modulation transfer function (MTF) in a model eye described in ISO 11979-2. The ISO 11979-2 requires MTF measurements using only a 3-mm aperture. In addition, the image quality of the Model SN6CWS was characterized by measuring MTF in a model eye that utilized a simulated cornea exhibiting typical adult human spherical aberration. Using the modified model eye, MTF measurements were made using both 3-mm, and 5-mm apertures. MODE OF ACTION AcrySof® IQ posterior chamber intraocular lenses are intended to be positioned in the posterior...

11. The clinical study of the AcrySof® Natural Single-Piece Lens (referenced in Tables 2 through 5) was conducted with the lens intended for implantation in the capsular bag only. There is no clinical data to demonstrate its safety and effectiveness for placement in the ciliary sulcus. It is recommended that viscoelastic be removed from the eye at the close of surgery with emphasis on the space between the posterior capsule and lens. This may be accomplished by gently depressing the IOL optic posteriorly with the I/A tip and using standard irrigation/aspiration techniques to remove the viscoelastic...

Step 6. Retract the viscoelastic cannula and remove the lens stop by gripping the arrow tab portion and pulling it straight up (Figure 6). Discard the lens stop. Do not attempt to add viscoelastic to the device after the lens stop has been removed or lens damage may result. Note: If any advancement of the plunger occurs prior to the removal of the lens stop, lens damage may have occurred and it is recommended to use another AcrySof® IQ IOL and AcrySert® C Delivery System. Figure 6 Step 7. When the lens stop has been removed, gently advance the plunger forward in one smooth, continuous motion...

Figure 8 Step 9. After confirming the lens is properly positioned and the haptics are folded properly, proceed with lens implantation by inserting the nozzle tip through the incision and positioning the nozzle tip at the anterior capsule opening. Step 10. Gently advance the plunger in one smooth, continuous motion. Do not advance the plunger too fast or lens damage may occur. It is recommended that delivery of the lens from the visual inspection position should take at least 5 seconds. As the lens begins to exit the nozzle tip, place the leading haptic into the capsular bag and continue to slowly...
