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.

The purpose of this study is to test the safety of an investigational drug product, IBI-10090 (DEXYCU), in children to treat eye inflammation (redness) caused by cataract surgery. DEXYCU was approved by the FDA in February 2018 for use in adults, however; has not yet been approved for use in children. The active ingredient in DEXYCU is dexamethasone. Instead of being an eye drop containing dexamethasone, DEXYCU remains in the eye as a tiny droplet and slowly releases dexamethasone over a period of approximately two to three weeks. After that time the droplet is absorbed by the body. Subjects 0 to 3 years of age who are undergoing cataract surgery will be eligible for this study. The study starts at screening visit which is 3-29 days before surgery. Any study-related procedures will be performed only after obtaining informed consent. Child will be in the study for about 90 days after signing informed consent. Enrollment in this study requires a total of 8 visits. If child is eligible he/she will be randomly assigned (like the flip of a coin) to either study group DEXYCU or control group, prednisolone acetate. Child will have study visits 1 day following cataract surgery, and then at approximately 1 week, 2 weeks, 4 weeks, 6 weeks and 3 months after surgery. All visits are standard of care visits for all cataract surgery patients except 2 weeks and 6 weeks after surgery visits.

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

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

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.
