Presbyopia: New clinical data reveals benefits of multifocal contact lens technology

ASX-listed contact lens manufacturer Visioneering Technologies (VTI) has been encouraged by new clinical data examining the performance of its soft multifocal contact lens in ‘mature presbyopes’.

At the recent Global Specialty Lens Symposium in Las Vegas, the US-based company revealed findings of a study that assessed the effectiveness of the NaturalVue Multifocal 1 Day lens in patients over the age of 55 with an add power of +1.75 or greater.

According to the company, of the 59 patients who completed the study, 71% had add powers of +1.75 or higher. This subgroup, which are considered a more challenging group to satisfy clinically, seemed to perform “extremely well” with the lens.

Specifically, the study demonstrated this group of patients had vision at every distance 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, such as without the use of readers. Also, near vision was significantly better with the NaturalVue Multifocal versus their previous correction,” VTI reported, according to Business Wire.

The NaturalVue lens is locally distributed by Contact Lens Centre Australia and is also approved for myopia control in Australia.

It uses a centre-distance, extended depth of focus design and relies on the visual cortex to suppress the high amount of plus in the lens, creating a virtual aperture that provides clear vision at all distances.

Key highlights of the clinical research update also include:

  • Stereo acuity is virtually the same as Best Corrected Spectacle Vision (BCSV).
  • Near vision is subjectively rated statistically significantly better than BCSV.
  • NaturalVue is within two letters of BCSV, at the intermediate distance.
  • Range of clear vision is 60% better with NaturalVue.
  • Near work, small print and reading books and newspapers is statistically significantly better in all three categories with NaturalVue than with habitual correction.
  • Less reliance on reading glasses is statistically significantly better with NaturalVue than habitual correction.
