Novel prototype contact lenses for myopia are currently being evaluated in clinical trials at Brien Holden Vision Institute in Sydney. The researchers say the lenses have been designed to slow the progression of myopia in children while offering better visual performance than current myopia management contact lenses.
Principal Investigator in the trial and senior research optometrist Jennifer Sha, said the lenses, which incorporate extended depth of focus (EDOF) principles, are being compared with a single vision lens over 12 months of wear to determine efficacy in slowing the rate of progression of myopia.
A shortcoming of contact lenses and spectacles designed to slow down the progression of myopia is that they can result in compromised visual performance
“A shortcoming of contact lenses and spectacles designed to slow down the progression of myopia is that they can result in compromised visual performance,” she said. “Regardless of the potential therapeutic benefits for patients, this has limited the uptake of these lenses and led to compliance issues. We’re endeavouring to design a lens that limits progression of myopia and is easy to wear.
“We finished a two year clinical study of prototype lenses in China recently and, taking the learnings from that, we’ve come up with this new design.
“We’re recruiting participants for this trial now, so if there are optometrists working in the inner Sydney area who have patients that might be interested we would love to hear from them.”
