Vision test
Including naked eye vision and the best corrected vision with glasses.
Intraocular pressure refraction examination
Rule out the possibility of high intraocular pressure and glaucoma. Including computer optometry, medical optometry and mydriasis optometry. Whether the optometry degree is correct or not directly affects the surgical effect.
Anterior inspection
Focus on corneal transparency, corneal scar, lens opacity, fundus examination for vitreous opacity, fundus lesions and so on.
Wavefront aberration inspection
Check whether there are high-order aberrations that seriously affect the visual quality except low-order aberrations such as myopia, hyperopia and astigmatism, and collect high-order aberration data as the basis for diagnosis and operation.
Other inspection
Corneal curvature examination
Rule out the possibility of keratoconus and corneal flattening.
Corneal thickness measurement
Preoperative attention
If the patient is highly myopic, pay attention to the depth of corneal center cutting and explain the situation to the patient before operation.
Corneal topographic examination
The main purpose is to understand the regularity and symmetry of the whole corneal surface and to exclude abnormal conditions such as keratoconus.
Pre-diagnosis can help patients understand the methods and treatment process of refractive surgery, and at the same time answer questions and eliminate concerns for patients, so that patients can better cooperate with doctors for examination and treatment. The initial examination is the detection and understanding of the patient's eyes and physical health to determine whether it is suitable for refractive laser surgery.
Patients must fill in the medical history questionnaire accurately, so that doctors can fully understand your physical condition. After a preliminary examination, you can roughly determine whether you are suitable for laser surgery and have a general idea of the expected effect of the operation. If it meets the requirements, our doctor will recommend different surgical methods according to your examination results and other conditions, and make an appointment for the corresponding follow-up examination items and time. At the same time, you must pay a certain inspection fee to ensure the smooth progress of the next inspection.
Initial examination items: vision, refraction, fundus (mydriasis), intraocular pressure, understanding the patient's medical history, computer optometry, corneal topography, corneal thickness and other necessary corresponding examinations.
After the initial visit, patients can return to the corresponding experts according to the doctor's advice and different appointment times. Follow-up is to further examine the patient's eyes before operation, accurately measure the physiological structure and refractive parameters of the eyes, and understand the patient's work and life, so that the surgeon can determine the most suitable operation method, formulate the best operation plan for the patient and ensure the quality of the operation.
Also note the following points:
(1) Before the operation, the patient should clearly explain the purpose and requirements of his operation to the doctor, and know whether he is suitable for the operation and the possible effects after the operation.
(2) Understand the general process of operation and the possible situations during and after operation.
(3) After deciding the operation with full understanding of the operation risks, sign the consent form.
(4) Before operation, soft contact lenses (contact lenses) should be stopped for 1-2 weeks, and hard contact lenses should be stopped for 3 weeks.
(5) Topical application of antibiotic eye drops 3 days before operation.
(6) Gaze training should be carried out before operation, so as to cooperate with doctors during operation.
(7) Have enough sleep the night before myopia surgery.
(8) Wash your face on the day of operation, and don't make up your eyes, so as to avoid the difficulty of cleaning and disinfecting your eyes before operation. If it is not thoroughly cleaned, some fine particles will enter the operation area. Do not use perfume and cosmetics with irritating smell, so as not to interfere with the working state of the laser machine and affect the effect of the operation.
(9) Do not wipe or touch your eyes with your hands after local eye disinfection before operation.
(10) When waiting before operation, relax, don't be nervous, and don't talk or talk loudly in the preparation room, so as to avoid excessive excitement and emotional loss during operation, which will affect the operation effect.
Preoperative guidance
Preoperative preparation
With the popularity of excimer laser surgery for myopia, it has brought an unprecedented clear world to the majority of myopia patients. In order to obtain the best curative effect, it is necessary to prepare for excimer laser surgery for myopia before operation to ensure better results.
1. Do not wear hard contact lenses for 3 weeks before excimer laser surgery for myopia, and do not wear soft contact lenses for 2 weeks before surgery.
2. Within 3 days before excimer laser surgery for myopia, please drop antibiotic eye drops daily according to the doctor's advice (tobias eye drops or Telibito eye drops can be used); Don't use other drugs for your own use without the doctor's permission.
3. Whether to use eye drops correctly after myopia excimer laser surgery is very important for the recovery and stability of vision, and I hope to get everyone's attention.
(1) When dropping eye drops, do not drop the liquid directly on the cornea. Please don't close your eyes forcibly to prevent the liquid medicine from overflowing, and don't let the bottle mouth touch your eyes, face, eyelashes or other objects to avoid pollution.
(2) If the doctor prescribes two or more kinds of eye drops, different eye drops should be dripped alternately with an interval of 5- 10 minutes, and the eye drops should be shaken evenly before each use.
4. Do not use any cosmetics and perfume on the day of myopia excimer laser surgery.
5. Eat digestible food properly before myopia excimer laser surgery. Please don't eat on an empty stomach or overeat.

recover
The recovery time of myopia surgery varies from person to person, but it is mainly determined by three factors:
1, different surgical methods, different recovery time.
There are many kinds of myopia surgery, and the recovery time of each myopia surgery is different, such as LASIK, femtosecond laser and ICL.
2. The degree of myopia before operation is different, and the recovery time is also different.
Generally, the degree of binocular vision before operation also determines the speed of postoperative recovery. Then if it is a patient with high myopia above 600 degrees, the recovery time of myopia surgery will definitely be longer than that of patients with moderate and low myopia.
3. The recovery time varies with different constitutions.
In most cases, people with good physical fitness will naturally recover faster, while those with poor physical fitness will recover relatively slowly, but not too much.
