Does optometry in Shanghai Eye Hospital have any side effects?
Eye hospitals are medical institutions specialized in treating eye diseases, and optometry is a common ophthalmic examination item. Many people worry about side effects when performing optometry. The following will elaborate on whether there are side effects of optometry in Shanghai Eye Hospital from four aspects.
Principle and process of optometry
Optometry is to determine the parameters such as vision state, diopter, eye axis length, etc. through a series of examinations on the eyes, so as to prepare glasses or prepare for refractive surgery. The usual optometry process includes visual acuity measurement, automatic computer vision measurement, automatic computer diopter measurement, axial length measurement, etc. These examinations are carried out with modern instruments and equipment, and generally will not cause obvious discomfort or side effects to the eyes.
First, the visual acuity is measured, that is, by asking the patient to read the letters or numbers on the visual acuity chart, the doctor can judge the vision according to the small fuzzy font that the patient can read. Next, automatic computer vision measurement is to determine the vision of the patient by identifying the image on the screen through an automatic vision meter. The automatic computer diopter measurement uses an automatic optometer to measure the patient's diopter.
Axial length measurement is to measure the axial length of the patient's eyeball through a special instrument, so as to accurately determine the eye condition. These examinations are mainly based on electronic equipment and instruments, and generally will not cause discomfort or side effects to the eyes.
Common optometry side effects and prevention
Although optometry generally does not produce obvious side effects, some people may have some uncomfortable symptoms. These side effects are generally temporary, and usually relieve themselves within hours or days. Common optometry side effects include:
1. Eye fatigue: It is easy to cause eye fatigue, resulting in eye fatigue or discomfort due to long-term staring at the target or light stimulation of the visual equipment. The way to avoid such side effects is to take proper eye rest and maintain good eye hygiene habits.
2. It is easy to get dizzy: during some optometry tests, such as vision code determination, it may be necessary to make patients pass special instruments, which may induce vertigo symptoms in some people. In order to reduce such side effects, the doctor can be informed of his own discomfort, and the doctor will adjust the examination method according to the specific situation.
3. Temporary intraocular pressure rise: When measuring the length of some eye axes, the patient needs to contact the equipment with his eyes. This exposure may cause a temporary increase in intraocular pressure, but it usually lowers itself within a few hours. For patients with eye diseases such as glaucoma, special attention should be paid and doctors should be informed of relevant conditions to avoid discomfort.
Precautions and conclusions
Before going to Shanghai Eye Hospital for optometry, patients can make some preparations to reduce the possibility of side effects during the examination:
1. Inform the doctor of personal eye disease history and medication history, and the doctor will decide the appropriate examination method based on this information.
2. Follow the doctor's instructions to make eye preparations, such as removing contact lenses in time to keep the eyes dry and clean.
3. Take the initiative to raise their own symptoms to the doctor, and the doctor will adjust the inspection method and instrument use according to the specific situation.
To sum up, Shanghai Eye Hospital generally has no obvious side effects when performing optometry. However, some uncomfortable symptoms may occur to individuals, such as eye fatigue, dizziness or temporary elevated intraocular pressure. These side effects are mostly temporary and usually relieve themselves. Before going to the hospital for optometry, patients should prepare their eyes and follow the doctor's instructions for examination. At the same time, they should actively inform the doctor of their personal conditions so that the doctor can take appropriate adjustment and preventive measures.
