1. Subjective VA Test
Comparison between subjective and objective VA tests yields more reliable and accurate data.
2. Wavefront Technology
Huvitz’ wavefront analysis algorithm goes beyond general refraction to conclude highly accurate and reliable cornea refractive power and index.
3. TFBUT Measurement and Meibography
Experience TFBUT function and Meibography to obtain thorough information about tear film/dry eye and meibomian gland conditions.
4. Wireless Communication
Experience wireless communication with HLM-9000 and HDR-9000 via Wi-Fi for data transmission.(RS-232 cable is also possible)
