What examinations should be prepared before the full femtosecond surgery in Zhongshan Ophthalmology Department?
Ophthalmic full femtosecond surgery is a widely used ophthalmic surgery in recent years, which can effectively correct myopia, hyperopia, astigmatism and other eye problems. However, before full femtosecond surgery, patients need to undergo a series of examinations to ensure the safety and effectiveness of the surgery. The following four aspects of preoperative examination will be described in detail.
Eye health examination
Before full femtosecond surgery, patients need to undergo a series of eye health examinations to assess whether the eye condition is suitable for surgery. These checks include:
1. Vision inspection: the visual acuity of the eyes is detected by an eyemeter or an automatic optometer, including the degree of myopia, hyperopia and astigmatism.
2. Refraction measurement: measure the refraction of the eye through corneal topography, corneal curvature meter and other equipment to determine the visual problems that need to be corrected during surgery.
3. Intraocular pressure test: use tonometer to measure the pressure inside the eyeball, and exclude the possible risk of glaucoma and other eye diseases.
4. Corneal thickness inspection: measure the thickness of the cornea through ultrasonic or optical coherence tomography and other equipment to evaluate the safety of the surgical operation.
The purpose of these eye health examinations is to evaluate whether the patient's eyes are suitable for full femtosecond surgery, so as to reduce the risk of surgery and improve the effect of surgery.
Overall Health Assessment
In addition to eye examination, a general health assessment is also required before full femtosecond surgery to ensure that the patient is in good health and has no contraindications. These include:
1. Inquire about the patient's medical history: inquire about the patient's allergy history, disease history and surgical history to assess whether the patient has contraindications.
2. Blood pressure measurement: measure the patient's blood pressure to ensure that it is within the normal range.
3. Routine blood and biochemical examination: check the patient's hemoglobin, white blood cell count, liver function, kidney function and other indicators to assess their overall health.
The purpose of the whole body health assessment is to ensure the safety of the patient's operation and avoid risks and complications during the operation.
Preoperative preparation guidance
Before the full femtosecond operation, patients need to follow the doctor's pre operation preparation guidance to ensure the smooth operation. The following are common guidelines for preoperative preparation:
1. Stop using contact lenses: patients need to stop using contact lenses for a period of time before surgery to ensure the recovery and stability of the cornea.
2. Avoid using cosmetics: The patient needs to avoid using eye cosmetics the day before the operation to reduce the risk of infection during the operation.
3. Ensure adequate rest: The patient needs to have adequate rest the night before the operation to ensure a good mental state during the operation.
The purpose of preoperative preparation guidance is to ensure the smooth operation process and reduce the risk of surgery.
Questions and Consultation
Before full femtosecond surgery, patients can put forward any questions and consultations, and fully communicate with doctors. This includes the operation process, recovery period and possible complications.
Through communication and understanding with doctors, patients can better understand the process and risks of surgery and make wise decisions.
In a word, before the full femtosecond surgery, Zhongshan Ophthalmology Department needs to carry out an eye health examination, a general health assessment, follow the preoperative preparation guidance, and have full questions and consultations with the doctor. These preparations can ensure the safety and effectiveness of the operation and improve the success rate of the operation.
