Wuhan Tongji Hospital femtosecond technology instrument is suitable for astigmatism
Wuhan Tongji Hospital is a well-known ophthalmic hospital. In order to provide more advanced treatment schemes, the hospital has introduced femtosecond technical instruments. So, is the femtosecond technology instrument suitable for astigmatism? This article will elaborate from four aspects.
Instrument principle and working mechanism
Femtosecond technology is a kind of corneal refractive surgery, which uses a laser system to micro cut the cornea to change its shape to correct refractive errors. With femtosecond technical instruments, doctors can accurately control the position, depth and shape of laser cutting, making it more suitable for the individual needs of patients. This corneal refractive surgery is applicable to a variety of refractive errors, including astigmatism.
Astigmatism is a common refractive error disease. The patient's corneal curvature is uneven, resulting in deformation of distant objects and blurred vision. Femtosecond technology instruments can correct astigmatism by changing the curvature of the cornea through laser cutting. The instrument can accurately calculate the parameters of laser cutting according to the specific situation of the patient, so that the surgical effect is more accurate and stable.
Operation process and postoperative recovery
The operation process of femtosecond technology instruments is usually divided into three steps: corneal dilation, laser system cutting, and finally corneal surface polishing. The whole process usually takes only a few minutes, and the patient can keep his head stable through a special fixation device during the operation.
After surgery, patients need to pay attention to the fact that the corneal tissue needs to be restored, so they may have discomfort such as blurred vision and dry eyes within a few days after surgery. The doctor will give the patient some eyedrops and nursing suggestions to help restore vision and relieve discomfort. Generally speaking, postoperative vision will gradually recover and reach the best state within a few weeks.
Operation effect and precautions
The operation effect of femtosecond technology instrument is very significant in the correction of astigmatism. Because the instrument can accurately calculate the laser cutting parameters, the vision correction effect after surgery is more accurate and stable. Many patients with astigmatism can obviously feel the improvement of vision after surgery. Distant objects are no longer deformed and vision becomes clearer.
However, it should be noted that although femtosecond technology has high safety and accuracy, not all astigmatic patients are suitable for such surgery. The doctor will conduct a comprehensive eye examination on the patient before the operation to assess the corneal condition and the feasibility of the operation. Patients also need to cooperate with doctors for preoperative preparation and postoperative care in order to obtain better surgical results.
Summary
With femtosecond technology and instruments, Wuhan Tongji Hospital can provide more accurate and stable surgical correction scheme for astigmatism patients. The principle and working mechanism of the instrument make the surgical process more accurate and the postoperative recovery effect better. However, patients need to conduct a comprehensive examination and assessment before considering the operation to ensure the feasibility and safety of the operation. In general, the femtosecond technology instrument has a high effect and adaptability in the correction of astigmatism, and has brought better quality of life to patients.
