Dr. Karpecki: How do you approach wavefront progressives? Do you recommend them for early presbyopes? Late presbyopes? Are there any issues associated with converting existing progressive addition lens (PAL) wearers?
Dr. Lowe: We've fit almost everyone who's been wearing PALs into one of the new wavefront PALs, and we've had very few issues. We've had some comments about the corridor. Patients say their vision is great in the iZon, but they feel more restricted than they were in the Physio 360. They need a little more time to adapt. In addition, with experience, we've improved our readings, making sure everything is in alignment. So now we have more success. However, we have the greatest success with first-time PAL wearers because it's easier for them to adapt.
Dr. Quon: Presently, I position the iZon progressive as the premium progressive. I firmly believe in the lens because I wear it. I have several top-of-the-line progressives, including many wavefront-guided and free-form designs. Most of these new progressives are excellent products, but when compared to the iZon progressives, the iZons provide me with a wider intermediate distance, larger reading area, clearer distance vision and greater visual comfort.
Initially, you'll experience what I call a little bit of visual overload when you wear them the first day. But you'll quickly adapt to the clarity of vision. Other than that, I think the iZon progressive is excellent.
