Intacs® Corneal Implants is a FDA Humanitarian Use Device (HUD) designed for the reduction or elimination of myopia and astigmatism in patients with keratoconus.

Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.

The purpose of this study is to identify and measure refractive errors of the eye as well as visual symptoms after cataract surgery.

The purpose of this project is to identify the postoperative alignment of toric intraocular lenses (IOLs) in patients who have undergone cataract surgery.

This study is for patients that have been diagnosed with relapsed/refractory neuroblastoma. The investigational drug given is eflornithine (DFMO) along with etoposide. DFMO is the investigational drug being used along with etoposide for treatment of neuroblastoma. Participants will undergo a number of standard tests and research-related procedures before being able to enroll in this study. Some risks include but are not limited to: fewer red and white blood cells, diarrhea, abdominal pain, loss of appetite, skin rash, seizure, difficulty swallowing and blurred vision. Participants can expect to be on this study for approximately 2 years. Participants will then be followed for up to 5 years after study completion.

Transcranial focused ultrasound (tFUS) is a new noninvasive way to stimulate the brain in an awake and alert person. We do not yet have an easily observable way to know whether we are in the right brain location with the correct dose for that person. We wonder if we can produce a transient change in someone's visual field, called a scotoma, and whether we can use that to determine the minimum tFUS dose for that person.

Children with amblyopia (lazy eye) are often treated with patch therapy. Patch therapy often results in leftover amblyopia and has many challenges associated with its use. This study will determine how traditional patch therapy results compare to those achieved with the Luminopia digital therapeutic system.

Dystonia is a movement disorder that causes muscles to contract and/or spasm. This may be painful and can affect the person's ability to complete daily tasks. Dystonia may affect one or multiple parts of the body. Botulinum toxins (BoNT) are the only approved drug in the United States to treat dystonia, and this is only for dystonia of the neck or the eye. There are currently no approved oral treatments for dystonia. Most current treatments only provide relief of symptoms.
The purpose of this study is to learn about the effects of the research drug (VIM0423), to find the best dose for treating dystonia, and to see how safe VIM0423 is for patients with dystonia.
This research study is studying VIM0423 as a possible treatment for dystonia. It is being developed to be a combination dose of: VMA-1001 given with VMA-1002.
• VMA-1001 and VMA-1002 will be taken in separate oral doses at the same time.
• VMA-1001 is an extended release (ER) modified version of trihexyphenidyl (THP).
• VMA-1002 is a formulation of bethanechol (BTC).
THP and BTC are medicines approved by the U.S. Food and Drug Administration (FDA); however, the Sponsor is investigating a different formulation of THP referred to as VMA-1001 and a different formulation of BTC referred to as VMA-1002. The purpose is to attempt to minimize some side effects of THP and is therefore considered an investigational drug in this study. An investigational use is one that is not approved by the FDA.
You may be in this study for up to 32 weeks from the time you consent until the last study visit.
You will be seen at the study site 6 times (Screening, Day 1, Day 30, Day 60, Day 95, and Day 125) and will complete 4 telephone calls (Day 6, Day 13, Day 20 and Day 105). You may be asked to come for extra visits at any time during the study if the study doctor decides that extra tests are needed for your safety.
Side effects associated with the study drug are dry mouth, dry eyes, blurred vision, dizziness, mild nausea and feeling nervous.
You do not need to take part in this study to receive treatment for your isolated dystonia. The study doctor will explain other options that are available to you. Your other choices may include treatment with other medicines for isolated dystonia, another investigational treatment, treatment that makes you feel more comfortable but will not have an effect on your isolated dystonia, or no treatment.
