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
Case Series Analysis: NaturalVue® (etafilcon A) Multifocal 1 Day Contact Lens and Myopia (N=32)
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)
Clinical Trial Results
