Imaging principle design
A standard ring is projected onto the patient’s cornea with a group of 760nm infrared light, the corneal astigmatism and axis are calculated according to the different curvature parameters in each direction of the corneal reflex ring. Use 850nm infrared light to project the Hartmann lenslet array into the fundus of the patient’s eyes, and separately calculate the parameters such as sphere, cylinder and axis according to the fundus reflection array. Use 850nm infrared light to project the Hartmann lenslet array into the fundus of the patient’s eyes, and separately calculate the parameters such as sphere , cylinder and axis according to the fundus reflection array.
Purpose
The instrument can be used to measure the curvature of the meridians of the center area about 3mm on the anterior corneal surface, that is the radius of curvature and curvature, so as to determine whether or not the cornea has astigmatism, astigmatism power and axial direction. It can also be used to measure the power of the patient, such as sphere, cylinder and axis. Used to measure the power of the patient, such as sphere, cylinder and axis.
Measurement mode
Manual measurement and automatic measurement. Aligning the measurement target at the corneal vertex, manual or automatic focus to clear state, the instrument will automatically measure the corneal curvature power. Use the same measuring method to automatically measure the powers of sphere, cylinder and axis. Manual measurement and automatic measurement. Aligning the measurement target at the corneal vertex, manual or automatic focus to clear state, the instrument will automatically measure the powers of sphere, cylinder and axis.
Patient
Non-contact measurement, the patient opens his eyes and looks right ahead, and move the target to complete the measurement (note the replacement of the chinrest paper and the forehead rubber cleaning) Non-contact measurement, the patient opens his eyes and looks right ahead, and move the target to complete the measurement (note the replacement of the chinrest paper and the forehead rubber cleaning)
