Detailed Explanation of Ophthalmology Metering Operation of Guangzhou Armed Police
Ophthalmic photometry is a common ophthalmic examination method, which is used to evaluate the refractive state of the eye and determine the degree of glasses matching. Guangzhou Armed Police Ophthalmology Department is a professional ophthalmic hospital with advanced photometric equipment and an experienced team of doctors. Next, we will introduce the operation process and precautions of ophthalmic photometry of Guangzhou Armed Police in detail.
Preparation before photometry
Before ophthalmic photometry, patients need to provide the ophthalmologist with detailed personal eye related information, including myopia, hyperopia, astigmatism and other diopters, and whether to wear contact lenses. The doctor will use this information to determine the target of light measurement.
Next, the doctor will provide the patient with a special pair of photometric glasses. The lens of this kind of glasses is a flat lens, which can shield the patient's original diopter, making the measurement results more accurate.
Before wearing photometric glasses, the doctor will check the patient's eyes to ensure that there is no disease or damage to the eye surface and cornea. Metering can only be carried out when the eyes are in good condition.
Operation steps of automatic metering
The Guangzhou Armed Police Ophthalmology Department uses an automatic light measuring instrument for ophthalmic light measurement. The operation is simple and fast. The specific steps are as follows:
1. The patient shall stably place his head on the head frame of the automatic light measuring instrument, and keep an appropriate distance between his eyes and the light measuring instrument.
2. The doctor can select the metering mode as required, including spherical lens metering, cylindrical lens metering and astigmatic axial metering.
3. The doctor will measure the patient's left eye and right eye one by one, let the patient see the image in the instrument, and the instrument will automatically adjust the light source and image to measure light.
4. The instrument will display the patient's refractive status according to the photometric results, including spherical lens degree, cylindrical lens degree and astigmatic axis.
Operation steps of manual metering
In addition to automatic light measurement, Guangzhou Armed Police Ophthalmology Department also provides manual light measurement service. This method requires doctors to operate. The specific steps are as follows:
1. The patient stably places his head on the head frame of the light measuring instrument. The doctor will use the manual light measuring collimator to adjust the light source and position of the instrument to ensure that it accurately shines on the pupil position of the patient's eyes.
2. The doctor will use the adjustment knob to adjust the lens of the instrument and gradually adjust it to the best degree that the patient can see clearly.
3. The doctor will observe the pupil reaction of the patient in the process of adjusting the lens to ensure that the measurement results are accurate and reliable.
4. Finally, the doctor will match glasses according to the results of manual photometry, and give the glasses degree and astigmatism axis suitable for the patient.
summary
The optometry operation of the Guangzhou Armed Police Ophthalmology Department is very professional and meticulous. Whether it is automatic or manual optometry, it can provide accurate refractive status assessment and glasses matching degree recommendation. With advanced equipment and experienced doctors, Guangzhou Armed Police Ophthalmology Department is committed to providing high-quality ophthalmic services for patients.
Through a detailed introduction to the ophthalmic photometry operation of the Guangzhou Armed Police, I believe that everyone has a more in-depth understanding of ophthalmic photometry. I hope this article will be helpful to readers.
