Kumase Eye Clinic is a specialized ophthalmology clinic located along Okayama Prefectural Route 238 in Naratsu, Kita-ku, Okayama City, conveniently situated approximately 3 minutes south of the Okayama IC on the expressway. The clinic operates under a two-physician system: Director Dr. Fumiaki Kumase handles general ophthalmology, medical retina, and cataract surgery, while Deputy Director Dr. Yumi Kumase specializes in general ophthalmology and low vision consultations. A notable feature of the clinic is its proactive approach to multifocal intraocular lenses in cataract surgery. The clinic offers domestically approved trifocal intraocular lenses including the "Clareon PanOptix" and the "Trinova (Acriva Trinova)," which is noted for reduced color irregularities, nighttime halos, and glare. The clinic has also been an early adopter of "ARGOS® with image guidance by Alcon," a system that enhances the precision of cataract surgery. Free informational sessions on multifocal intraocular lenses are held regularly, providing patients with the opportunity to make well-informed decisions about their treatment. The low vision clinic is conducted by appointment every Monday afternoon, offering specialized care for those concerned about their visual function. Online appointment booking is available for both new and returning patients, English-language support is offered, and the facility is equipped with parking and barrier-free access. Morning reception hours are from 8:45 to 11:30, while afternoon hours vary by day. The clinic is closed on Wednesday afternoons, Saturday afternoons, Sundays, and public holidays.
