What examinations need to be done before Xi'an ophthalmic surgery?
With the continuous development of modern medical technology, more and more people choose ophthalmic surgery to improve their eyesight. Ophthalmic surgery is an important medical procedure. In order to ensure the safety and effectiveness of surgery, doctors usually require patients to carry out a series of examinations before surgery. The following is a detailed introduction to the examinations to be carried out from four aspects before ophthalmic surgery.
Routine ophthalmic examination
Before ophthalmic surgery, the doctor will conduct routine ophthalmic examination to assess the patient's eye health and the feasibility of surgery. These examinations include measurement of intraocular pressure, examination of corneal curvature, visual acuity test and fundus examination. Through these examinations, doctors can know whether the patient has eye diseases or other eye problems, and develop personalized surgery plans based on the examination results.
In addition, patients also need to provide detailed medical history information, including past eye surgery, eye drug use, eye diseases, etc., to help doctors fully understand the patient's eye health.
Corneal topography
Corneal topography is a commonly used examination method to evaluate the shape and curvature of the cornea. In ophthalmic surgery, corneal topography can help doctors determine whether patients are suitable for laser surgery or corneal transplantation. Through this examination, doctors can understand the curvature, thickness, shape and other characteristics of the cornea, and further determine the operation plan and parameters.
Common examination methods of corneal topography include cylindrical fluoroscopy, iris photography and corneal coaxial fluoroscopy commonly used in regular ophthalmic hospitals. These examination methods are non-invasive and painless, and can quickly obtain accurate corneal topographic map data, providing reference for surgery.
Fundus examination
Fundus examination is one of the important means to judge the health of the eyes. Before eye surgery, doctors usually perform fundus examination to understand the condition of retina, optic nerve and other tissues. Through fundus examination, doctors can find problems such as retinal holes, retinopathy and optic neuropathy, and judge whether patients are suitable for ophthalmic surgery.
Fundus examination usually uses equipment such as fundus camera, and doctors will magnify and analyze the fundus image. This examination needs the support of laboratory instruments, so it usually needs to be carried out in the hospital. Through fundus examination, doctors can assess the health of eye tissues and reduce the risk of surgery.
Whole blood cell count
Ophthalmic surgery is a kind of surgery requiring local anesthesia, so the whole blood cell count of patients is one of the very necessary inspection items. This examination can assess the patient's blood system health, including platelet count, red blood cell count, white blood cell count and other important indicators.
Whole blood cell count can be completed by taking blood samples from patients for laboratory testing. Generally, the doctor will advise the patient to carry out this examination some time in advance to ensure that the patient is in good health and can safely undergo eye surgery.
Summary
The preparation of ophthalmic surgery is the key link to ensure that the surgery can be carried out safely and effectively. Routine ophthalmic examination, corneal topography, fundus examination and whole blood cell count are necessary examination items before ophthalmic surgery.
Through these examinations, doctors can assess the patient's eye health, eye structure characteristics and overall health, develop personalized surgical programs, and reduce the risk of surgery.
Before receiving ophthalmic surgery, patients should follow the doctor's instructions and carry out various examinations as required to ensure that their physical conditions are suitable for ophthalmic surgery, so as to achieve the desired effect.
