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 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...

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...

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...

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...

are Black. The control (SA30AL) subject population was 96.6% Caucasian, 2% Black and 1.4% other. The mean age for the total population receiving the Model SB30AL in at least the first operative eye is 72.9 years. Similarly, the mean age for the total population receiving the Model SA30AL (control) is 71.9 years. 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...
