65 EW CORNEA March 2016 Contact information Collins: mjc@collinsvision.com biplanar, and 1 or 2 AK monopla- nar incisions are placed, as well as a small monoplanar Wong incision/ pocket. "Each incision can have shared or independent architecture (from single to triplane) and can be placed or dragged to various loca- tions out to a 12.5 mm diameter." Dr. Collins has recently been working with Wong incisions and said the idea for this came from the observation that femto incisions sealed better with hydration of the incision roof. "The next logical step was to place a Wong incision anteri- or to the primary incision," he said. "With minimal hydration, we get an amazing seal." The arcuate incision options are flexible, as the laser is capable of cre- ating single or paired arc incisions. "Paired arcs are not required to be of the same arc length, diameter, and do not have to be locked to the same meridian," he said. "The arcu- ate incision angle is also adjustable, and the laser is capable of creating intrastromal arcuate incisions as well." These intrastromal arcuate cuts are sometimes used to facilitate toric IOL alignment or opened and extended postoperatively to treat residual astigmatism in the case of undercorrection, Dr. Collins said. Surgically induced astigmatism Femto incisions are more predictable and precise, allowing for more con- trol and precision with astigmatism correction, Dr. Collins said. There is no way to make manual incisions the exact same depth, length, shape, angle, and optical zone, which is possible with a femtosecond laser CRI. "Of course there are other vari- ables that come into play with astig- matic correction, but if we can max- imally control these variables, we will get more predictability," he said. A big struggle for some femtosecond surgeons, he added, is the ability to place the primary incision as far out on the limbus as they typically would with a keratome incision. "The more anterior the incision, the more it can impact the surgically induced astigmatism." Because the cornea is applanated during the corneal incision mode, the laser is able to achieve greater precision and performance when placing cuts close to the limbus, he said.
