Can femtosecond surgery in Wuhan Union Medical College Hospital correct vision problems?
Wuhan Union Medical College Hospital is a comprehensive hospital with a long history and rich experience, with advanced equipment and professional medical team. In recent years, femtosecond laser surgery, as a common way of ophthalmic surgery, has been widely used in correcting vision problems. This article will elaborate on the femtosecond surgery in Wuhan Union Medical College Hospital from four aspects: preoperative examination, surgical principle, surgical effect and applicable population.
Preoperative examination
Before the femtosecond surgery in Wuhan Union Medical College Hospital, doctors will conduct a comprehensive preoperative examination of patients. This includes intraocular pressure examination, corneal topography, fundus examination, etc. Through these examinations, doctors can determine the patient's eye condition and determine whether it is suitable for femtosecond surgery. The accuracy and comprehensiveness of preoperative examination is an important guarantee to ensure the operation effect.
In addition, during the preoperative examination, the doctor will know the patient's medical history and personal conditions in detail, including whether there is a history of allergy and drug use. This will help doctors better evaluate the adaptability of femtosecond surgery to patients.
Operation principle
Femtosecond laser surgery is to change the curvature of the cornea by precisely cutting the cornea with the high-energy laser beam generated by the laser, so as to improve vision problems. This operation method has the advantages of rapid, minimally invasive and fast recovery.
In femtosecond laser surgery, doctors will use the laser beam generated by femtosecond laser to accurately cut corneal tissue. This cutting has high precision and controllability, and can be treated individually according to the actual situation of patients. During the operation, the doctor will accurately adjust the laser parameters according to the patient's corneal shaping needs and corneal anatomy characteristics to achieve the correction of corneal curvature.
Surgical effect
Femtosecond surgery can effectively improve myopia, hyperopia, astigmatism and other vision problems. After surgery, patients can generally recover their vision quickly and no longer rely on glasses or contact lenses. Moreover, femtosecond surgery is minimally invasive, with less damage to the eyes and lower risk.
However, the duration of the surgical effect is also related to individual differences, and some patients may have vision regression within a period of time after surgery. In addition, the success of the operation is also closely related to the patient's eye condition and the accuracy of the operation.
intended for
Generally speaking, femtosecond surgery is a feasible treatment for patients with severe vision problems such as myopia, hyperopia, astigmatism, etc. But not everyone is suitable for femtosecond surgery. For pregnant women, teenagers and some patients with special eye diseases, the risks and effects of surgery should be carefully considered.
Before choosing the surgical method, patients should consult professional doctors for comprehensive evaluation and consultation. Doctors will decide whether femtosecond surgery is suitable according to the patient's individual conditions and surgical risks.
Summary
To sum up, the femtosecond surgery in Wuhan Union Medical College Hospital can effectively correct vision problems. The accuracy and comprehensiveness of preoperative examination is the key guarantee for the success of surgery. Through accurate operation principle and operation, the operation can effectively improve patients' vision problems. However, the effect of surgery varies from individual to individual, and the applicable population also needs to be selected reasonably according to individual conditions. Before choosing the operation method, patients should consult professional doctors to comprehensively assess the risks and effects of the operation.
