Analysis of curative effect of femtosecond surgery on myopia in Nanjing Drum Tower Hospital
Nanjing Gulou Hospital is a well-known general hospital, which has been attracting much attention in the field of ophthalmic treatment. Among them, femtosecond surgery, as a common corrective surgery for myopia, is favored by patients. So, does the femtosecond surgery of Nanjing Drum Tower Hospital really cure myopia? Next, it will be elaborated from several aspects.
Operation principle
Femtosecond surgery, also known as femtosecond Laser assisted Laser In Situ Keratomileusis (FS-LASIK for short), is a kind of surgery that removes corneal tissue through laser and changes corneal curvature to correct diopter. Compared with the traditional laser in situ keratomileusis (LASIK), femtosecond laser is used to replace the traditional corneal grinding blade, thus reducing the damage to the cornea.
First, the patient will receive corneal measurements to determine the depth and shape of the cut required for surgery. Then, the femtosecond laser will send ultra fast pulse laser at a very high speed, creating tiny bubbles to delaminate the cornea, thus controlling the accuracy and depth of cutting. Finally, through the cutting action of these tiny bubbles, the laser can cut the cornea to change its shape, thus correcting the diopter.
treatment effect
Femtosecond surgery, as a common corrective surgery for myopia, its therapeutic effect depends on many factors, including the level of surgical technology, the patient's corneal condition and the recovery after surgery.
According to the clinical observation and patient feedback of Nanjing Drum Tower Hospital for many years, femtosecond surgery has a good curative effect in most patients. After surgery, the patient's vision improved significantly, the degree of myopia decreased, and even reached the standard of naked eye vision. In addition, patients can also avoid wearing glasses or contact lenses to improve their quality of life.
However, femtosecond surgery is not for everyone. For some patients with thin cornea, sensitive cornea or high degree of cornea, femtosecond surgery may have some risks. Therefore, when deciding on the operation plan, doctors need to make a comprehensive assessment and decision based on the situation of different patients.
Surgical risk
Although femtosecond surgery has achieved good results in the treatment of myopia, there are still some surgical risks.
First, the operation may lead to postoperative complications, such as dry eye, infection, etc. Although these complications are relatively rare, patients need to pay close attention to them after surgery and seek medical advice in time.
Secondly, femtosecond surgery may cause some damage to the cornea during the treatment process, which may cause corneal refractive instability or corneal scars after surgery. These problems may not only affect the effect of vision repair, but also may require further surgery or treatment.
Therefore, before deciding to accept femtosecond surgery, patients need to fully understand the risks of surgery and have a detailed discussion with doctors.
Summary
To sum up, the femtosecond surgery in Nanjing Drum Tower Hospital has achieved remarkable results in the treatment of myopia. Through laser correction of corneal curvature, the patient's vision can be significantly improved, and the degree of myopia will also be reduced. However, femtosecond surgery is not suitable for everyone, and there are certain surgical risks. Therefore, the patient needs to communicate and evaluate with the doctor in detail before deciding to accept the operation to ensure the safety and effectiveness of the operation.
