How does Xi'an ophthalmic medical equipment work?
Ophthalmic medical equipment is an indispensable tool for ophthalmic departments in modern hospitals. They can help doctors diagnose and treat diseases, and improve medical efficiency and accuracy. This article will elaborate the operation principle and function of Xi'an ophthalmic medical equipment from four aspects: laser treatment equipment, fundus camera, corneal topography and perimetry.
1. Laser treatment equipment
An ophthalmic hospital in Xi'an is equipped with advanced laser treatment equipment, such as excimer laser surgery system. The operation of this device relies on excimer laser, which accurately irradiates the eye tissue of patients through high-energy laser beam, thus changing the shape and curvature of the cornea, and achieving the effect of treating myopia, hyperopia, astigmatism and other eye diseases.
The operation process of laser treatment equipment usually includes the following steps: First, the doctor will use anesthetic eye drops to anaesthetize the patient's eyes, so that the patient will feel no pain during the operation. Next, the doctor uses the laser surgery system to locate and fix the eyeball. Then, the doctor sets the laser treatment parameters according to the patient's eye disease, and starts the laser device for treatment. The whole process usually does not exceed several minutes.
The operation principle of laser treatment equipment is to use the energy of laser beam to change the structure of eye tissue, so as to achieve the purpose of correcting vision and treating eye diseases. However, laser treatment equipment can only be operated by specially trained ophthalmologists to ensure the safety and success rate of the operation.
2. Fundus camera
Fundus camera is a key tool in ophthalmic medical equipment for examination of fundus diseases. An ophthalmic hospital in Xi'an is equipped with a high-resolution fundus camera, which can take clear pictures of important structures such as blood vessels, nerves, and macula in the eyes of patients.
Fundus camera works by using high-resolution camera and optical lens to image the eyeball. After dilating the patient's pupil, the doctor points the fundus camera at the patient's eye and triggers the shutter to take a picture. Then, doctors analyze the photos through computer software to evaluate the condition and treatment plan of fundus diseases.
The operation process of fundus camera requires strict operation technology and professional knowledge, and doctors need to have diagnostic experience and interpretation ability of fundus lesions. Through fundus camera, ophthalmologists can more accurately diagnose and treat a variety of eye diseases, such as glaucoma, retinopathy, etc.
3. Corneal topographer
Corneal topographer is a device used to evaluate corneal morphology, which can help doctors understand the shape, curvature, thickness and other important parameters of the cornea. An ophthalmic hospital in Xi'an has introduced an advanced corneal topographer, whose operating principle is based on optical principles and camera technology.
When using corneal topography, the patient needs to put his chin on the bracket and reduce blinking. The doctor aims the beam at the patient's eyeball by adjusting the equipment. At this time, the device will automatically rotate to obtain corneal morphological data from multiple angles. The corneal topography instrument will use these data to generate corneal topography, and doctors can judge whether the cornea is normal or abnormal through the topography.
The corneal topography can be used to correct vision, diagnose corneal diseases and evaluate postoperative effects. It not only provides the objective data of corneal morphology, but also provides important reference for doctors to formulate treatment plans and surgical programs.
4. Visual field tester
The perimetry is a device used to evaluate the visual field of patients, which helps doctors detect and diagnose fundus diseases, such as glaucoma and retinal diseases. An ophthalmic hospital in Xi'an is equipped with an advanced perimetry, which can provide accurate and fast perimetry data.
The principle of perimetry is to capture the light reflection within the field of vision through multiple optical detection instruments, and then display the patient's field of vision data through data analysis and image processing. Doctors can judge whether there is visual field defect or abnormality based on these data.
The perimetry is very important for early detection and quantification of the visual field damage of glaucoma, and can also be used to assess the severity of retinopathy and track the therapeutic effect. Through perimetry, doctors can take measures as soon as possible to avoid further deterioration of the disease.
Summary
Xi'an ophthalmic medical equipment includes laser treatment equipment, fundus camera, corneal topography and perimetry. Laser treatment equipment treats eye tissues through laser; Fundus camera is used for examination of fundus lesions; Corneal topography was used to evaluate corneal morphology; The visual field of the patient was evaluated by the perimetry. The operation principle and operation method of these devices need the participation and operation of professional doctors. The introduction of these modern ophthalmic medical equipment has improved the medical level of the hospital's ophthalmic departments and provided more accurate and efficient ophthalmic diagnosis and treatment services for patients.
