Data shows that patients with > +1.75 ADD
power and above age 55 achieved vision comparable to spectacle
acuity at every distance with NaturalVue Multifocal1
US-based medical device company and producer of the NaturalVue®
(etafilcon A) Multifocal 1 Day Contact Lenses, Visioneering
Technologies, Inc. (ASX: VTI) (‘Visioneering’ or ‘The Company’)
presented at the Global Specialty Lens Symposium (GSLS) an update
of clinical data with mature presbyopes, those patients with >
+1.75 ADD power and over 55 years of age.
Contact lenses to address presbyopia (true bifocals) have been
in existance since the late 1940’s, however, only about 8% of the
100-million presbyopes2 are fitted with a bifocal or multifocal
contact lens. Patients are promised improved vision, like when they
were younger, but find that most multifocal lenses don’t deliver.
In a study regarding performance of multifocal contact lenses, eye
care professionals reported that as many as 85% of their patients
experienced at least one area of compromised vision at near,
intermediate or distance3. The issue of compromised vision is only
exacerbated among those patients who are considered ‘mature
presbyopes’; those with an ADD power of +1.75 or greater and over
55 years old. These patients are at significant risk of dropping
out of contact lenses altogether since traditional multifocal lens
designs tend to fail with medium and high ADD powers, which occurs
as people age.
A recent analysis of a subset of the NaturalVue Multifocal
Pre-Market Evaluation Study yielded some interesting results among
this group of mature presbyopes. Of the 59 patients who completed
the study, 71% had ADD powers of +1.75 or higher. This subgroup,
often considered a more challenging group of patients to satisfy
clinically, seemed to perform extremely well with the NaturalVue
lens. Specifically, the study showed that this group of patients
had vision at every distance with the NaturalVue Multifocal that
was comparable to best corrected spectacle acuity. These patients
reported that they could meet 85% of their daily needs with the
NaturalVue lens alone (i.e. without the use of readers). Also, near
vision was significantly better with the NaturalVue Multifocal
versus their previous correction.
Highlights of the Clinical Research
Update
- Stereo acuity is virtually the same as Best Corrected Spectacle
Vision (BCSV).
- Near vision is subjectively rated statistically significantly
better than BCSV.
- NaturalVue Multifocal is within 2 letters of BCSV, at the
intermediate distance.
- Range of clear vision is 60% better with NaturalVue
Multifocal.
- Near work, small print and reading books and newspapers is
statistically significantly better in all 3 categories with
NaturalVue Multifocal than with habitual correction.
- Less reliance on reading glasses is statistically significantly
better with NaturalVue Multifocal than habitual correction.
The NaturalVue Multifocal 1 Day contact lens is a unique,
center-distance, extended depth of focus design. It relies on the
visual cortex to suppress the high amount of plus in the lens, thus
creating a virtual aperture that provides clear vision at distance,
intermediate and near. The lens performed well not only versus
existing contact lens designs but also against best corrected
spectacle vision as well. For more information on the NaturalVue
