It is used for those with astigmatism. It stays where you put it. The toric Visian comes in four sizes (overall diameter), and the size the surgeon selects is based on white-to-white or sulcus-to-sulcus measurements. An ICL is … The Visian Implantable Collamer Lens (ICL) is made of collamer, a substance naturally found in the body. The lens is also delivered with a positioning diagram. Good for Patients Ineligible for LASIK – Thin or irregular corneas, dry eye syndrome, very high prescriptions, or large pupils can disqualify someone from LASIK surgery. “Anyone who is comfortable with ICLs, or even intraocular surgery in general, can very quickly master this,” he says. As a result, night vision can be better than with other procedures No Dry Eye– Because corneal nerves are not disrupted during ICL implantation, the surgery does not produce dry eyes. As today’s devices become more sophisticated, options designed to help those with limited vision are increasing. “Where toric lenses are available they represent about 40 percent of the ICLs that are used.”, John A. Vukich, MD, an assistant clinical professor at the University of Wisconsin, Madison, medical monitor for Staar Surgical and a principal investigator for the FDA study of the Visian Toric ICL, notes that the Visian Toric has been used extensively outside the United States. At the same time, moving it to place it exactly where you want it is not difficult.”, Dr. Vukich says the learning curve for a surgeon implanting these lenses will be low. “The Visian ICL is currently distributed in 64 countries, and 63 of them already have access to the toric lens,” he says. The online calculator gives you a solution and specifies the lens from inventory that you need, along with the instructions for aligning it for that specific patient. Dr. Vukich notes that allowing this small adjustment eliminates the need for Staar to create a different lens for every possible axis of astigmatism, in addition to different lens sizes, spherical powers in half-diopters from 3 to -20 and astigmatism powers up to 6 D in half-diopter steps (outside the United States—the range of astigmatic correction available in the United States will be determined by the FDA if and when the lens is approved). “More than 100,000 of these toric lenses have been placed worldwide.” “All the phakic lens implants give excellent visual results, especially for high myopes,” notes Dr. Price. “However, there are nuanced techniques we’ve learned over the years that will optimize your outcomes—little tips that make things easier for the surgeon. and with reporting to Staar appears to be low—0.02 percent—and primarily
