Soft Multifocal Contact Lenses

A Contact Lens Alternative for Correction of Myopia

The ever-increasing prevalence of myopia in the general population, and in children in particular, has generated tremendous interest in effective, safe and convenient treatment alternatives.

Visioneering Technologies, Inc. (VTI), a leader in pioneering contact lens technology, has developed an innovative design for myopia correction using a soft multi-focal contact lens whose Extended Depth of Focus allows the patient to see the world like a picture from a disposable camera, with all points (foreground, background) in focus at the same time.

In short, it optically corrects existing myopia.

A VTI contact lens design was effective in animal studies and shows continued promise in human clinical trials for decreasing three known visual risk factors of myopia:

  • Lag of accommodation
  • Amplitude of accommodation
  • Peripheral hyperopia

10 Practices who had started using NaturalVue® Multifocal in myopic children

Control: Each child served as his/her own historical control

  • Age, Spectacle refraction at time of last exam and date of last exam
  • What type of correction was being used
  • Calculated Diopters progression per month since last exam, then annualized

Use of NaturalVue® Multifocal

  • Age
  • Spectacle refraction at initial visit
  • Spectacle refraction at follow up visit – minimum 6 months
  • Calculated D progression per month since last exam, then annualized

Demographics

  • 36% male; 64% female
  • Age at fitting with NaturalVue® Multifocal: 10.98 + 2.95 years (range 6 to 19)
  • Length of wearing NaturalVue® Multifocal: 10.94 + 4.76 months (range 6-25)
