iDESIGN® Refractive Studio Specifications For Site Preparation/Installation Product Description The iDESIGN® Refractive Studio System measures the wavefront of the eye within a defined range using the HartmannShack sensor. The sensor evaluates the deflection of rays emanating from a small beam of light projected onto the retina. The measurements determine regular (sphero-cylindrical) refractive errors and irregularities (aberrations) that cause reduced visual function. The iDESIGN® Refractive Studio also measures and displays corneal topography, pupil size, and keratometry. Wavefrontlaser assisted in situ keratomileusis (LASIK) treatments can be calculated using measurements obtained from the iDESIGN® Refractive Studio. Treatment calculations for wavefront-guided LASIK include full gradient topography for propagating the wavefront and compensating for the cosine effect (peripheral loss of laser energy due to corneal curvature). Recommended Room Requirements • Do not place the unit near windows or in a room that cannot be sufficiently darkened to allow the patient’s pupils to dilate naturally • Ambient operational temperature range: 60° – 80°F (15° – 27°C) • Humidity: Relative humidity no less than 35% and no greater than 65% (non-condensing) • Barometric pressure range: 11 – 16 psi (76 – 110 kPa) Storing Requirements Before Installation When storing the system before installation, adhere to the following storage requirements: • Storage temperature must be between 14° – 140°F (-10° – 60°C) at a relative humidity no less than 0 – 85% (non-condensing) CAUTION: U.S. Federal Law restricts this device to sale, distribution, and use by or on the order of a physician or other licensed eye care practitioner. ATTENTION: Reference the Operator’s Manual for a complete listing of Contraindications, Warnings and Precautions as well as other Indicati
