Ring iris Eyeground Eye being measured Measurement target The eyeground is observed from the center by shooting from the pupil section ring iris image into the eyeground. Measuring principle (kerato function) Kerato ring image projected on the cornea.2-5 Principles 2-5-1 Kerato-refractometer unit 1. Target image projection to eyeground (ref function) The fundamental principle is the same as for previous models: the measurement target is projected from the iris image of the pupil section and the light reflected from the eyeground is detected. The following figure is a general diagram of this method. The reflected image detected here undergoes image processing to compute the radius of curvature and the refracting power of the cornea. － 11 － R-TRK1P-0-0809-02 . 2.7) Kerato ring As shown in the figure. the image is projected onto the eyeground from the pupil ring iris and the image reflected from the eyeground is detected with the CCD CAMERA. the kerato ring is projected on the cornea and the reflected image is detected with a CCD CAMERA. The detected image is image processed and the way in which the circle is converted shows the refraction of the eye. Size: 3mm (in the case of R7.

The axes are set up so that the intersection of the X-axis and Y-axis is the center of the ring. 2 Suppose that the difference of the coordinates for the inner diameter and the outer diameter of the ring is only 7 units. the image is divided up like a checker board. an error of one reference unit could be ignored. The right and left lines are at regular intervals and parallel to the Y axis and the up and down lines are at regular intervals and parallel to the X axis. This circle or ellipse is measured. Y axis X axis A B － 16 － R-TRK1P-0-0809-02 . if the smallest unit that can be resolved is 1 unit. 3 If the reference units are made smaller than the measurement precision. as in the figure below. but if the difference is an odd multiple. In other words. then the center cannot be measured accurately. the center between the outer diameter and the inner diameter is either Circle A or B. In this case. if the difference between the inner diameter and the outer diameter is an even multiple of the minimum resolution. then the center can be measured accurately. Image processing (1) Objective To find the centers of the inner diameter and outer diameter of the ring image reflected back from the eyeground. In summary: 1 The reflected image detected with the CCD CAMERA is stored into memory with one data bit for each checker board square.A.C. data.

For the focus direction (Z axis). The jet of air blown on the patient's eye causes the cornea to change its shape in the sequence in the following figure. determining the amount of the change in shape from the change in the amount of the light reflected and detecting the condition at the instant of applanation. The reflected light to the applanation sensor is weak when the cornea is spherical (in the following figure at the left). the maximum reflected light is detected. Cornea Convex Plane Concave Plane Convex The change in shape is measured from the difference between the received light from the infrared LED and the reflected light detected by the intensitometer. Measurement method is as follows. Measurements are made by blowing an air jet on the cornea of the patient's eye. then to calculate the intraocular pressure from the numerical value of the cylinder pressure required to make the cornea to a certain plane surface area. When the cornea is made to a certain plane surface area (in the following figure at the right). Applanation sensor Eye Nozzle Alignment/applanation LED － 20 － R-TRK1P-0-0809-02 .2-5-2 Non-contact meter unit The principle of this instrument is to blow an instantaneous jet of compressed air on the cornea. (Refer to the following figure. L=f (CP). Chamber inner pressure Corneal thickness measurement principles Slit light is slantingly emitted for the patient's cornea and the light reflected by the front and backside of the cornea is brought in by the line sensor. The intensity of the light reflected on the cornea (L) is detected by the intensitometer as the function of the chamber inner pressure (CP).) Using the function in the figure. The corneal thickness is calculated by using the interval (L) between the front reflection image and backside reflection image on the line sensor. which is continuously measured by the pressure sensor. the chamber inner pressure (Pc) is determined for the maximum reflected light intensity (Lmax).
