Tomey RT-7000 Autorefractor Topographer
Tomey RT-7000 Autorefractor Topographer all-in-one unit. Patients are able to receive a comprehensive inspection without the hassle of moving from station to station. With one touch the RT 7000 is able to quickly switch from Ref-Kerato mode to Corneal Topography mode as the light cone appears from the measuring head and the Ref-Keratometer is transformed to Topographer.
- Three Functions in One Instrument

- Corneal Eccentricity Index for “Ortho-K Lens” (CEI)
Easy & Speedy Touch Screen Alignment
The Touch Alignment of the RT-7000 quickly aligns the eye cener with the center of the screen by simply touching the eye shown on the screen. The Auto Alignment and Auto Shot functions then start measurement immediately.
Dual CCD technology for Refractometry
Two CCD cameras capture images for observation and measurement while also providing accurate measurement data.
The viewing angle of the fixation target is wider to help patients feel relaxed during the process.
When it is difficult to measure pseudophakic or cataract eyes in normal mode, the device automatically switches to IOL or Cataract mode to match the state of examination of the eyes being examined
New Indices for Keratometry: KAI, KRI
The Corneal Irregular Astigmatism display function is installed to expand the possibility of Keratometer. This is the new function to measure the level of Corneal Irregular Astigmatism, which was difficult in the past.
The Indices of KAI and KRI that show the Corneal Irregular Astigmatism are displayed with its three levels (A/B/C) at Keratometry
KAI: (Kerato-Asymmetry Index)
The Index indicating the asymmetry of cornea. This index becomes larger when the corneal shape is asymmetric.
KRI: (Kerato-Regularity Index)
The Index indicating the regularity of the cornea (higher-order irregular astigmatism). This index becomes larger when the corneal surface is not smooth.
It is possible to confirm the detail of the corneal shape with Topographer by switching to the Topography Mode with out only “ONE TOUCH” if irregular astigmatism is suspected with KAI and KRI.
Fourier analysis of TMS separates and quantifies the refracting power on the surface of the cornea to “Spherical”, “Regular Astigmatism”, “Asymmetry” and “Higherorder irregularity” show the Corneal Irregular Astigmatism.
Diameter Measurement of Cornea and Pupil
Measurement can be done easily by moving the two cursors on he display to the boundary of Cornea or Pupil. This is useful for deciding the diameter of contact lens and other contact lens fitting practices.
