Focused Ultrasound Therapy
Focused ultrasound is a noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with myopia (nearsightedness) or hyperopia (farsightedness). This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue.
How it Works
Where the beams converge, the ultrasound produces neuromodulation of the ocular cortex, potentially enabling myopia and hyperopia to be treated without surgery. While initial work has been accomplished, there is still much to be done before this technology will be widely available.
Advantages
The primary options for treatment of myopia and hyperopia are very limited to external corrections (glasses, contacts or invasive surgical corrections), and this could be a novel solution.
Focused ultrasound can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.
Clinical Trials
At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of myopia and hyperopia.
The Foundation updates these pages regularly, but with the increasing number of clinical trials, we want to be sure that our audience has the latest information available. Therefore, we also added the website search information for the above trials. If you click here, it will take you to the latest information available from https://www.clinicaltrials.gov/.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for myopia and hyperopia is not yet approved by regulatory bodies or covered by medical insurance companies.
