Optometric Clinical Update 2018 What s New @ CHU Y. Ralph Chu, MD Chu Vision Institute 1
SMILE 2017 Chu Vision Institute U.S. LVC Market Impact of ReLEx SMILE ZEISS ReLEx SMILE will grow LVC market First major innovation in U.S. LVC market in 16 years (Femto-LASIK in 2000) New LVC option for refractive surgeons to offer patients fearful of LASIK and those waiting for the next thing. Unlike PRK and LASIK, SMILE was developed in Europe and arrives in the U.S. as an established technology; 1,000,000+ procedures performed internationally to bolster physician and patient confidence. ZEISS ReLEx SMILE receives FDA approval 2016 2
ReLEx SMILE Characteristics and Benefits LASIK-like outcomes with a one-step, minimally-invasive procedure¹ Effectiveness and safety of procedure well received by patients (99% satisfied, 96% would have refractive surgery again).² No flap-related complications (e.g. flap detachment) All-femtosecond laser procedure in one step without need to move the patient LASIK ReLEx SMILE incision approx. 6 mm 1. Comparison of visual ad refractive outcomes following femtosecond laser assisted LASIK with SMILE in patients with myopia or myopic astigmatism. Journal of Refractive Surgery 2014 Sep, Sri Ganesh, Rishika Gupta. 2. Survey conducted as part of FDA clinical study. ReLEx SMILE Characteristics and Benefits Removing tissue from deeper corneal layers result in less impact on the corneal surface and nerves and lower risk of dry eye. 1 1.

5 April 2018 ReLEx SMILE with the VisuMax Introduction How does a femtosecond laser work? Ultrashort (1 fs = 10-15sec), infrared laser pulses trigger an optical breakdown known as photodisruption and generate a plasma. The plasma produces a shock wave that produces cavitation bubbles that sever tissue in a focused area without injuring surrounding tissue. Placing thousands of these bubbles next to one other allows the creation of cuts of virtually any shape within the cornea.

ReLEx SMILE with the VisuMax Introduction Video ReLEx SMILE with the VisuMax FDA Indications for Use Indications for Use: Reduction or elimination of myopia - 1.00 D to -8.00D (-8.01 D to -10.0 D will trigger a flagged warning), with - 0.50D cylinder and MRSE -8.25D in the eye to be treated in patients who are 22 years of age or older with documentation of stable manifest refraction over the past year. 5
Similar to LASIK Postop SMILE ReLEx SMILE with the VisuMax Routine Post-Operative Management Routine follow up visits after SMILE 1 Day 1 Month 3 Months 1 Year Further optional visits 1 Week 6 Months Annually Additional visits as required according to the situation. 6
ReLEx SMILE with the VisuMax Expectations: Three Stages 1. Immediate & day one (swelling, healing response) 2. First few weeks 3. Three/four months (swelling, healing, adaptation) (adaptation presbyopic) Slight discomfort Dry eye sensation Night vision halos Slight blurring Visual fluctuations Visual fluctuations Morning to evening Day to day NV good/dv bad DV good/nv bad Always use both eyes Don t test each eye Prescribe temporary glasses if necessary Remain aware of adaptation process Often happens overnight Retreatment if required FDA Study Study Design & Objectives Design & Objectives Prospective, multi-center, open label, single-arm study Proposed sample size: 360 subjects Unilateral treatment with 12-month follow-up period Fellow eye treatment with approved laser procedure (clinical data not part of pivotal study) Objective: to evaluate the safety and effectiveness of the VisuMaxFemtosecond Laser lenticule removal procedure for the reduction or elimination of myopia from -1.00 D to -10.00 D with -0.50 D cylinder and MRSE -10.25 D (subjects with -0.50 D cylinder were enrolled, but the cylinder was not treated as part of the clinical trial) 7
