March 2012 1 T he restoration of accommodation is generally consid- ered a holy grail for cataract and refractive surgery. Until recently, it has remained largely beyond the reach of IOL design technology. The most generally accepted IOL-based strategy today is to extend the range of vision by creating multiple fixed focal points. Unfortunately, this multifocal approach tends to compromise visual quality. The Crystalens (Bausch + Lomb) is the first accommodative IOL to be approved by the U.S. Food and Drug Administration (FDA). The lens is designed to mimic the motion of the natural crystalline lens to provide quality vision without the compromises typical of multifocal lenses. The latest version of the Crystalens, the Crystalens AO, incorpo- rates Bausch + Lomb's proven aspheric lens technology into the design, further enhancing vision and contrast sensitivity. It looks good on paper, but does the lens actually deliver? EyeWorld brought together a team of experts to talk about their experiences with the Crystalens AO. Design and capabilities Dr. Lindstrom: The first question I would like to ask each of you is, why is Crystalens AO part of your offering? What is it about this lens, its design and capabilities, both objectively and subjectively, that led you to include it in your practice? Dr. Dell: I was an original investigator in the FDA-required clinical study for the Crystalens when we developed the technology, so I have a lot of experience using the lens. I know where it excels and where it doesn't. Any time we treat a patient with an IOL, we try to achieve a near correction, we try to treat presbyopia, and we walk a fine line between quantity of vision and quality of vision. I find that in that equation, I tend to err on the side of better visual quality and perhaps slightly less quantity. I would much rather get that greater quality of vision for the intermediate and distance areas of focus than reduce their quality in exchange for a little more near. Dr. Lindstrom: The Crystalens AO is basically the same aspheric optic we would get with monofocal IOLs like the Akreos MI-60 (Bausch + Lomb), an aspheric monofocal optic, so we get the same quality we would expect from those lenses.
