At Eye Clinic is a specialized ophthalmology clinic in Bangkok's Chatuchak district. The clinic focuses on oculofacial plastic surgery, cataract treatment, glaucoma care, and dry eye management.
The clinic is led by Dr. Nattawut Wanumkarng and Dr. Pinita Wanumkarng, a husband-and-wife team who both hold concurrent positions at Bumrungrad International Hospital.
