Pre operative examination items of femtosecond surgery in Nanjing Aier Hospital
With the development of science and technology, femtosecond laser surgery has become a common way to correct myopia. As a well-known medical institution in Nanjing, Nanjing Aier Hospital provides professional femtosecond surgery services. Before the operation, the hospital will carry out a series of preoperative examinations to ensure the safety and effectiveness of the operation. The following are the main items of the preoperative examination of femtosecond surgery in Nanjing Aier Hospital:
Ophthalmic examination
Before the operation, the ophthalmologist will conduct a comprehensive ophthalmic examination for the patient. These tests are designed to assess the patient's eye health and ensure that they are suitable for femtosecond surgery. Ophthalmic examination usually includes:
Visual examination
Vision examination is the first step to evaluate patients' vision problems. Ophthalmologists will use an eye chart or other vision testing device to measure the naked vision and correct vision of patients. In this way, we can understand the degree of myopia of patients and evaluate the expected effect of surgery.
Corneal topography
Corneal topography is an important method to evaluate corneal morphology. Through corneal topography, doctors can understand the curvature, astigmatism and other morphological characteristics of the cornea, so as to determine the laser parameters required for surgery.
Intraocular pressure measurement
Intraocular pressure measurement is a method to detect the internal pressure of the patient's eyes. This is an important step in assessing whether the patient has eye diseases such as glaucoma. Measurement of intraocular pressure can also help doctors judge the risk of possible complications during surgery.
general physical checkup
In addition to ophthalmic examination, general examination is also an indispensable part before surgery. The general examination can help doctors understand the overall health of patients and ensure the safe operation. The general examination mainly includes:
Blood test
Blood examination can evaluate the patient's hemoglobin level, platelet number and other important indicators. These indicators can reflect the anemia risk and coagulation function of patients, and help doctors evaluate the safety of surgery.
electrocardiogram
Electrocardiogram is a method of recording patients' cardiac electrical activity. During femtosecond surgery, patients need to be in a certain position of lying flat and head fixation, so their heart health needs to be checked to avoid accidents during surgery.
Blood pressure measurement
Blood pressure measurement is an important index to evaluate the blood circulation of patients. By monitoring the patient's blood pressure, doctors can determine whether the patient has systemic diseases such as hypertension, and adjust some details during the operation.
Fundus examination
Fundus examination is an important step to evaluate the internal structure of the eye. Fundus examination mainly includes
Fundus image examination
Fundus image examination uses digital imaging technology to record the image of the patient's fundus. This examination method can help doctors to assess the health of the patient's retina, optic nerve and other structures, and eliminate the possible risks of retinopathy during surgery.
Fundus retinal fluorescein angiography
Fundus retinal fluorescein angiography is a kind of imaging technology, which can make blood vessels appear by injecting dye, and then observe and evaluate the pathological changes. This examination can help doctors understand the condition of patients' retinal blood vessels and ensure the safety of surgery.
Ocular surface examination
Eye surface examination is an important means to evaluate the health of cornea, conjunctiva and eyelid.
Conjunctival examination
Conjunctival examination can evaluate whether there are inflammation, conjunctival sac and other problems in the patient's conjunctiva. If these problems are not found and handled in time, they may affect the surgical effect.
Palpebral examination
The eyelid examination mainly evaluates the structure and function of the patient's eyelid. By checking whether the patient's eyelids have diseases, it can ensure the safety during the operation and prevent infection.
To sum up, the preoperative examination items of femtosecond surgery in Nanjing Aier Hospital include ophthalmic examination, general examination, fundus examination and ocular surface examination. These examinations can comprehensively assess the patient's eye and general health, and provide basic guarantee for the smooth operation.
