The iDESIGNTM Refractive Studio

Make every treatment a true original

The iDESIGNTM Refractive Studio is a topo-integrated, wavefront-guided technology.1

Next-level treatment planning

  • Topo-integrated, wavefront-guided treatment planning enables true personalization (when available)1

Expanded diagnostic capabilities

  • Topographic maps, views, and summary metrics1

Improved workflow

  • Shorten, automate, and eliminate steps for faster turnaround

Committed to your practice’s success

  • Approved for myopia (with or without astigmatism), hyperopia, (with or without astigmatism), mixed astigmatism, and monovision LASIK1

Support and expertise from a proven leader

When you measure better, you treat better

The iDESIGNTM Refractive Studio, the next level of treatment planning with a proprietary INSIDE+OUT approach that adds corneal topography measurements to the wavefront-guided procedure.1

Map the entire optical pathway inside the eye with wavefront analysis

  • Measures both lower and higher aberrations1
  • ~1,257 data points capture the most minuscule distortions2
  • 25X more precise than conventional measurements like manifest refraction*3
  • 5X the resolution with high-definition Hartmann-Shack Wavefront Sensor†4

Map the entire surface of the cornea with corneal topography

  • Uses a built-in full-gradient topographer to capture ~1,200 x- and y-slopes to interpret minuscule variations in the corneal surface2

Topo-integrated wavefront-guided technology

  • Individual patient’s topographic data are used to vertex wavefront-guided data from pupil to corneal plane1
  • Individual patient’s topographic data are used to calculate accurate treatment delivery by taking into account cosine compensation1

The difference is in the data.

The next level of personalization.

The iDESIGNTM Refractive Studio adds a comprehensive set of diagnostics capabilities to ensure a more informed view of the patient’s refractive error.

2. Neal D. iDesignTM system: Going beyond WaveScan. Presented at the ESCRS Amsterdam 2013. REF2016RF0025.
3. Based on mathematical calculation: WaveScan WaveFront System/iDESIGNTM Refractive Studio = 0.01D. Manifest refraction =0.25D. Manifest 0.25 ÷ iDESIGNTM Refractive Studio 0.01 = 25. 25X more precise.

4. Based on mathematical calculation: WaveScan System = ~240 micro-refractions. iDESIGNTM Refractive Studio = 1,257 microrefractions. iDESIGNTM Refractive Studio 1,257 240 = 5.23X the resolution.
