Located in Ryugasaki City, Ibaraki Prefecture, Bannishi Eye Clinic provides a wide range of ophthalmological services centered on cataract and vitreous surgery. A notable feature of the clinic is its proactive adoption of digital surgery using 3D monitors, creating a safe surgical environment with high-precision imaging. Patients also benefit from reduced microscope light intensity, minimizing glare and discomfort. In September 2025, the clinic became an early adopter in Ibaraki Prefecture to install ALCON's latest cataract and vitreous surgery system "UNITY VCS," achieving a less invasive surgical environment. In addition to day surgery for cataracts and vitreous conditions, the clinic offers diverse treatments including SLT laser therapy and MIGS (minimally invasive glaucoma surgery) for glaucoma, orthokeratology, ICL, Botox treatment, IPL therapy, and Luxa tear eye drops for myopia progression control. Equipped with specialized visual field testing instruments and anterior segment OCT, the clinic also emphasizes early detection of glaucoma. Physicians from Juntendo University Urayasu Hospital, Tokyo Medical University Ibaraki Medical Center, and University of Tsukuba provide outpatient care, ensuring a medical system with high expertise. English-speaking staff are available, and the clinic features parking and barrier-free facilities, creating an accessible environment for a wide range of patients.
