contrast sensitivity, as well as high and low contrast distance, intermediate, and near vision. First, we wanted to make sure that we targeted the lenses as accurately as possible to remove any bias. With the Crystalens AO, I've found that the sweet spot is between plano and –0.5 D spherical equivalent. Meanwhile, I targeted the multifocal to about plano to about +0.5 D. In our study, we achieved these targets. With the Crystalens AO, we achieved a spherical equivalent of –0.3; with the Tecnis and ReSTOR, we achieved near plano. Uncorrected distance vision was 20/20 to 20/25 in almost all the lenses at high contrast, but at low contrast, the accommodating lens performed better in the low lighting conditions. In intermediate, the Crystalens AO wins over the multifocals, with a statistically significant difference. Dr. Lindstrom: Was there any differ- ence between the ReSTOR and the Tecnis multifocal IOLs at intermediate? 4 March 2012 Advancements in accommodating IOL technology: A global perspective " We believe that we have to customize the solution; each patient is absolutely different from another. We have to identify the objectives of our patients for their vision after surgery, and we have to have all the types of lenses available to us, including the Crystalens AO, so that we can find the solution that will make the patient happy after surgery " Joaquin Fernandez, M.D. Dr. Ang: The ReSTOR did a little better since it's a +3 add. With near vision, we expect the Crystalens AO to not perform as well as the multifocals; with high contrast, our data does suggest that the multifo- cals perform better, but this is not statistically significant. However, at low contrast, the Crystalens AO makes up for that difference; vision with the multifocals decreases in terms of low contrast near vision. So the Crystalens catches up. It's not statistically differ- ent as long as you target patients to be close to 0.5 D. In terms of contrast sensitivity, the accommodative IOL is better than the multifocals, and that difference was significant in our study. There was also a significant difference in terms of halos and starbursts between the Crystalens AO and the two multifocals. Crystalens or multifocals? Dr. Lindstrom: I expect we all have done both multifocal and Crystalens implantations. Are there any particular Conclusions from Dr. Ang's study on Crystalens AO
