Josui Eye Clinic, located in Saiwai-cho, Tachikawa City, Tokyo, is an ophthalmology specialty clinic. A notable feature of this clinic is its same-day surgery services for cataracts and vitreoretinal diseases. Cataract surgery is performed under local anesthesia, typically taking about 10 minutes, and patients can return home after approximately 15 minutes of rest post-surgery, which is appreciated for minimizing patient burden. For vitreous surgery, a minimally invasive technique involving small openings in the conjunctiva is used to treat conditions such as diabetic retinopathy and retinal detachment. Laser treatments for retinal tears and diabetic retinopathy are also available on an outpatient basis. The clinic is equipped with a dedicated operating room and various medical devices, providing a highly specialized treatment environment. Patients are advised to visit without contact lenses, and since fundus examinations may cause pupil dilation that affects driving ability, confirming transportation arrangements in advance is recommended. The clinic has parking facilities, is barrier-free accessible, and accepts credit cards and electronic payments. Consultation hours are from 9:00 AM to 5:00 PM on weekdays and Saturdays, with Wednesdays, Sundays, and public holidays closed.
