SMILE refractive surgery procedure expands laser vision correction options for US surgeons to offer patients
ZEISS ReLEx® SMILE, a new revolutionary minimally-invasive laser eye surgery procedure, which was recently approved by the U.S. FDA3, expands the vision correction options for myopia, or nearsightedness, that U.S. refractive surgeons can now offer their patients. Over 750,000 SMILE procedures have been performed internationally since its introduction in 2011, with over 1000 surgeons regularly performing the procedure. After leading the IDE clinical trial as the Medical Monitor from 2012 to 2016, during which more than 350 eyes were treated, Jon G. Dishler, M.D. at the Dishler Laser Institute was the first to commercially perform the newly approved procedure on a patient in the U.S. on Friday, March 3, 2017. Since March 2017, numerous U.S. surgeons have been trained and are experiencing outstanding success with patients using this new procedure.
ReLEx SMILE, a high-precision procedure, is an innovative minimally-invasive approach to myopia correction that is only available on the VisuMax® femtosecond laser from ZEISS. In the SMILE procedure, surgeons correct patients’ myopia using the VisuMax femtosecond laser to create a precise disc-shaped lenticule within the cornea, which is then removed by the surgeon through a small incision, also created by the laser. SMILE requires only one laser to perform the entire treatment.
“SMILE, the first major advancement in laser vision correction since the 1990s, has been rapidly growing around the world with refractive surgeons seeing excellent refractive outcomes, fast visual recovery, and minimal discomfort for their patients,” says Jim Mazzo, Global President Ophthalmic Devices at Carl Zeiss Meditec. “Now SMILE has achieved two more milestones: the first commercial procedures in the U.S., and over three-quarter of a million procedures performed worldwide.”
“We are pleased that refractive surgeons now have a new laser vision correction option to offer patients, and that this latest advancement in refractive surgery is helping to reinvigorate the market, both in the U.S. and around the world,” continues Mazzo. “ZEISS would like to thank the many doctors, scientists, researchers and other individuals who have worked to bring this innovative, breakthrough laser vision correction technology to patients helping to usher in a new era for refractive surgery.”
ZEISS is also conducting an IDE trial in the U.S. on astigmatic myopia and has submitted an international study outside the U.S. for the treatment of hyperopia to further broaden the spectrum of SMILE for more patients.
Integration of new Barrett Suite with IOLMaster SWEPT Source Biometry helps cataract surgeons achieve target refraction and reduce the risk of refractive surprises
ZEISS has fully integrated into the IOLMaster® 700 SWEPT Source Biometry® the latest generation of Barrett IOL (intraocular lens) power calculation formulas – Barrett Universal II, Barrett Toric, and Barrett True-K – as one convenient suite, the Barrett Suite, for more accurate prediction of refractive outcomes.
The formulas integrated into the new Barrett Suite, which incorporates the influence of the posterior corneal surface, have been shown to be more accurate in predicting target refraction.3, 4, 5 The IOLMaster 700 automatically applies these formulas depending on the intraocular lens (IOL) selected and the refractive surgery status of the patient. These latest generation formulas and SWEPT Source Biometry can help surgeons more easily improve refractive outcomes and reduce refractive surprises.
“The combination of SWEPT Source OCT biometry with my formulas offers the potential for exciting results and whole new calculation options,” says Graham D. Barrett, M.D., inventor of the Barrett IOL calculation formulas. “I am excited to see how the SWEPT Source OCT technology of the IOLMaster leverages the full potential of my formulas.”
ZEISS Cataract Suite markerless helps surgeons achieve precise toric IOL alignment
ZEISS Cataract Suite markerless brings together products for precise markerless toric IOL alignment6 allowing cataract surgeons to skip the manual pre- and intra-operative marking steps and manual data transfer. IOLMaster 700 and 500, when integrated into the toric IOL workflow of ZEISS Cataract Suite markerless6, can further help surgeons achieve precision in the OR6. Studies have shown that up to 99% of patients achieved post-operative refractive cylinder within +/- 0.50D7. A reference image acquired by ZEISS IOLMaster during routine biometry is the starting point for achieving precise markerless toric IOL alignment in the OR. The image of the eye is taken automatically in case of astigmatism along with the keratometry measurement – all with one device. Both the reference image and keratometry data are transferred to CALLISTO eye®, the computer-assisted cataract surgery system from ZEISS. During surgery, the reference image is used for intraoperative matching with the live eye image, and data needed to assist surgeons in precise4 toric IOL alignment is injected into the eyepiece of the ZEISS OPMI LUMERA® surgical microscope.
“Our focus at ZEISS is to provide doctors with superior solutions to achieve the best possible outcomes for their patients,” says Dr. Ludwin Monz, President and CEO of Carl Zeiss Meditec. “We have designed ZEISS Cataract Suite markerless to simplify the toric IOL implantation and alignment workflow for greater efficiency and precision so surgeons can deliver excellent outcomes for every patient.”
ZEISS diagnostics integrated with FORUM simplifies clinical workflow for efficient chronic eye disease management
ZEISS FORUM® eye care management platform brings together patient exam data and imaging across the extensive diagnostic portfolio from ZEISS helping doctors to more easily diagnose and manage chronic eye disease. Retina Workplace and Glaucoma Workplace from ZEISS streamline the clinical workflow and facilitate clinical case visualization for doctors to easily view and assess multimodal imaging and data.
For CIRRUS™ OCT, ZEISS has introduced ZEISS AngioPlex® with AngioPlex Metrix™, the latest application for retinal disease analysis in its comprehensive portfolio of diagnostic solutions. AngioPlex Metrix from ZEISS quantifies vascular and perfusion density allowing doctors to objectively assess change over time and the foveal avascular zone with automatic detection of FAZ area and circularity.
