S P R I N G 2 0 1 8 9 Corneal Incision While traditional cataract surgery has previously depended on a surgeon's use of a hand-held diamond or metal blade to create the incision that allows access to the cornea and the sclera, the femtosecond laser provides a precise surgical plane for the incision. When coupled with an optical coherence tomography (OCT)—a 3D image of the eye—the use of a femtosecond laser enables the surgeon to create an incision across all planes and within a specified depth, location and length. Not only does this precision increase accuracy in the procedure, it also supports the self-sealing properties of the incision, reducing the likeli- hood of infection. Anterior Capsulotomy Prior to the recent advancements in cataract surgery, the eye sur- geon typically created an opening in the eye's capsule with a nee- dle in order to remove it and allow access to the cataract. During this step in the cataract surgery, called an anterior capsulotomy, it is critical that the remaining portion of the lens capsule stays intact and is not damaged. It is this capsule that will provide a place for the artificial lens implant to rest. Using a femtosecond laser to perform laser cataract surgery provides an increased reproducibility and accuracy. Additionally, laser capsulotomies allow eye surgeons to more precisely center and position the intraocular lens (IOL), a crucial factor in deter- mining a positive refractive outcome for the patient. Cataract and Lens Fragmentation e use of a femtosecond laser prior to traditional phacoemul- sification enables the surgeon to soen the cataract prior to removal. ese soer and smaller pieces need less energy during the removal process, resulting in a reduced risk of distortion and burning of the incision. Another key advantage of using the least amount of energy necessary during the phacoemulsifica- tion process is a decreased risk of breakage of the capsule. e preservation of the eye's natural capsule helps ensure a positive visual outcome for the patient. Less energy in the eye during the surgery is also less traumatic to the endothelial cell layer of the cornea. is usually results in a quicker recovery of vision for the patient. Addressing Astigmatism e standard method of addressing astigmatism during cataract surgery is a procedure known as limbal relaxing incisions (LRI) or astigmatic keratotomy (AK). It involves the surgeon using a diamond blade to manually place small incisions around the periphery of the patient's curved corneal meridian.
