Located in front of Ishiyama Station, Koseikai Ishiyama Eye Clinic, a medical corporation, provides ophthalmology services on the first floor of the Omi Railway Building. The clinic offers specialized care for causes of vision decline, including refractive errors such as myopia, hyperopia, and astigmatism. They provide vision correction through glasses or contact lenses, as well as vision rehabilitation using eye drops and training. In particular, for parents whose children were identified with abnormalities during school vision screenings, they assess whether recovery is possible or if glasses are needed. They also recommend early consultation when severe hyperopia is detected in infants. Additionally, the clinic is attentive to the risks of serious conditions such as retinal detachment that may accompany the progression of severe myopia, and focuses on preventing delayed vision development and amblyopia. The facility is equipped with a parking lot and offers services in English.
