for a thin profile and easy delivery. All of the AcrySof lenses are very forgiving during the implan- tation through a cartridge and into the capsular bag. One of the more endearing properties of the platform's ability is that the lenses are gentle to the ocular structures and have the flexibil- ity to tolerate the implantation through a very small incision in a reliable fashion. This allows me to reduce my wound size, while still using a reliable portfolio of advanced technology IOLs. As I mentioned earlier, this is a family of products that goes from an aspheric monofocal to an as- pheric toric to an aspheric multifo- 6 Years of experience have convinced me this is the best family of lenses for the majority of patients I have been a long-time user of the AcrySof (Alcon, Fort Worth, Texas) family of lenses, ever since my residency. In my hands, the AcrySof IOL continues to be a very comfortable and convenient product to use. One of the benefits of choosing this family of lenses—from the IQ to the IQ Toric to the IQ ReSTOR IOL—is just that: It's a family of products all built on the same platform. And that platform has shown time and time again to provide patients with phenomenal visual outcomes. That, in turn, means I inherently know how the lens is going to perform as it's unfolding, as it's being inserted, and as I'm position- ing it, regardless of which variation of the lens I'm using. There are numerous aspects of the AcrySof IOL line I appreciate: It has excellent centration, and it's constructed out of optimal material EW Chicago 2012 Sunday, April 22, 2012 6 AcrySof platform provides confidence, consi monofocals and advanced technology lense by Jason Jones, M.D. " Because the AcrySof is a family of products, the newer user can gain a lot of experience with monofocal lenses and have more confidence when beginning to use the advanced technology platforms " Jason Jones, M.D. Please refer to page 12 for important safety information about the Alcon surgical products described in this supplement. Ernest continued from page 5 spherical monofocal IOLs. Correct- ing relatively small amounts of corneal astigmatism with the low- powered T3 reduced the post-op astigmatism by about 0.75 D more than the spherical lens (bearing in mind these patients had 0.75 D to 1.38 D of pre-op astigmatism). 2 Given the small amount of SIA we noticed in these patients, the residual effects were basically non-existent (see Figure 1). It's been my experience that calculating SIAs is not difficult. Warren Hill, M.D., has created a website that allows surgeons to calculate their SIAs as well as their SD. The program can be downloaded off doctorhill.com/physicians/ download.htm. According to Dr. Hill, the SIA Calculator has been designed to calculate, by means of vector analysis, the amount of SIA created during the cataract surgical procedure. To gain the most benefit, I suggest that surgeons use the same instrument for both pre-op and post-op K measurements. If the SDs can be minimized, using an IOL calculator will give you great success with toric IOLs. If the SDs are variable, however, it's likely surgeons will be disappointed with their initial outcomes. For those who are not consistently calculating their SIAs, I recommend taking about 30-50 eyes, measuring the pre- op and post-op Ks, running a simple vector analysis, and calculating not only the SIA but the SDs. After the first 50 cases or so, I recommend surgeons revisit wound construction and architecture. Once the SIAs are lower and surgeons start seeing more consistent outcomes, it becomes much easier to approach the T3 lens with a high degree of certainty about visual outcomes. Like the cataract procedure itself, every step builds on the one before it. If surgeons know their SIAs, they can look at their SDs and work on getting those deviations as narrow as possible. Keeping tight SDs has given me the confidence to know I can easily treat lower levels of astigmatism very effectively with a lens-based procedure. References 1. Ernest P, Hill W, Potvin R.
