December 2013 cells behind the IOL optic. It can be treated successfully by opening the posterior capsule centrally with an Nd: YAG laser. 3. Snowflake degeneration is a slowly progressive opacification associated with lenses made of PMMA, resulting from long-term exposure to ultraviolet light. The snowflake lesions are typically found within the anterior third of the optic substance. They are generally not observed in the periphery (due to protection from the iris), and do not disappear in the dry state. This type of degeneration has been observed mostly in lenses implanted between the early 1980s and mid 1990s. 4. Glistenings are fluid-filled microvacuoles, most often associated with hydrophobic acrylic lenses. They can typically be found within the entire optic substance of the lens, and unlike the lesions involved in snowflake degeneration, glistenings disappear when the lens is dry. 5. Cell deposits may be observed on the IOL surface after cataract surgery, and usually are composed of giant cells, macrophages, and fibroblast-like cells. They usually degenerate and detach from the IOL surface in the postoperative period. If necessary, they can be "dusted off" the IOL surface by using a Nd:YAG laser. EW 7. Ozaki L.

THINK PATIENT SAFETY "LENSAR's collection of imaging technologies makes it possible to precisely image the exact location and contour of the posterior capsule, which is the 'Holy Grail' for performing safe ReLACS." – Kerry Assil, MD EW CATARACT Contact information Morris: caleb.morris@duke.edu Mamalis: nick.mamalis@hsc.utah.edu Werner: liliana.werner@hsc.utah.edu At LENSAR™, we're always thinking ahead. That's why we designed the LENSAR Laser System with your patients' safety in mind. LENSAR's rotating camera captures up to 16 images from the anterior cornea to the posterior capsule and reconstructs a 3-D model of the eye. Because you'll see exactly where the relevant anatomy is in the eye for all grades of white or brunescent cataracts, you can feel secure in designing and executing an optimum treatment that will maximize outcomes without putting your patients at risk.
