A method of corneal pachymetry comprising the steps of:
the first step is as follows: firstly, checking the name and the eye difference of a patient, guiding the patient to lie on an examination bed with the head facing the examiner, assisting the patient to put the head position, and if necessary, putting a pillow on the patient;
the second step is that: opening the lower eyelid of a detected person, ordering the detected person to rotate the eyeball, dropping a drop of local anesthetic in the conjunctival sac, wiping the flowing liquid medicine with a cotton swab, paying attention to the fact that the eye dropping medicine is firstly mixed with the patient to be an anesthetic, and causing slight burning;
the third step: turning on the fixation lamp, adjusting the center of the eye to be inspected to watch, covering the eye to be inspected, instructing the patient to watch the fixation lamp by the other eye, observing the eye position of the eye to be inspected, and adjusting the position of the fixation lamp until the eye to be inspected is the first eye position;
the fourth step: taking off the probe cap, respectively opening the upper eyelid and the lower eyelid of the tested eye by the thumb and the forefinger, holding the measuring probe by the other hand, pressing a START key on the operating table 5 to START measurement when the pressure on the eyeball cannot be applied;
the fifth step: the probe is vertically and lightly placed in the center of the cornea, pressure cannot be applied, the thickness of the cornea is automatically measured by the corneal thickness gauge 4, the position of the probe is slightly moved, and the thinnest thickness in the center of the cornea is measured;
and a sixth step: if the peripheral cornea thickness needs to be measured, stepping on a green pedal, entering a second group of data measurement, measuring the thickness of four positions, namely upper, nasal, lower and temporal positions of the pupillary margin, and keeping a probe perpendicular to the cornea at the measured position during measurement;
the seventh step: the cornea thickness gauge 4 automatically stores five data which are acquired last in each group, the LIST key on the operation table 5 is pressed to display the data, each group of data is selected by moving the key left and right, and the CLEAR key on the operation table 5 is pressed to delete the topmost data in the group, which is also the data which are measured last;
eighth step: after the measurement is finished, the PRIENT key on the operation table 5 is pressed to print a result, the eye to be measured drops a drop of chloramphenicol, the patient is asked to get up, the name of the patient and the name of the examiner are written on the result, the patient is handed over after checking, the probe is sterilized by a 75% alcohol cotton swab, the probe is wiped by a dry cotton swab, the probe cap is covered, the probe is put back to the original position, and the fixation lamp is turned off.
