Can half femtosecond surgery in Kunming Hospital cure myopia?
In modern society, myopia has become a common vision problem. Many people hope to get rid of the shackles of glasses or contact lenses and find a more effective treatment. Half femtosecond surgery in Kunming Hospital is one of the most concerned methods to treat myopia. So, can the half femtosecond surgery in Kunming Hospital really cure myopia?
Technical Principles
Half femtosecond surgery, also known as laser corneal correction surgery (LASIK), is a surgical method based on laser technology. During the operation, doctors will use laser to remove the tissue on the corneal surface, thus changing the corneal diopter and correcting myopia. This operation usually requires no hospitalization, and the operation time is short and the recovery period is fast.
The principle of half femtosecond surgery is different from that of traditional laser surgery. Traditional laser surgery uses continuous laser, while half femtosecond surgery uses pulsed laser. This kind of pulsed laser is more accurate than continuous laser, and can correct the shape of cornea more accurately, thus improving the effect and safety of surgery.
In addition, half femtosecond surgery also has the characteristics of individualization. The doctor will make accurate assessment and surgical design according to the patient's eye conditions to ensure the success rate and safety of the operation.
Efficacy and risk
Half femtosecond surgery is effective in the treatment of myopia. Patients who have undergone surgery can often significantly improve their vision problems and get rid of dependence on glasses or contact lenses. The vision after surgery recovers quickly, and most people can feel obvious changes within a few days to weeks.
However, half femtosecond surgery also has certain risks. Complications such as infection, dry eyes and inaccurate astigmatism correction may occur during the operation. In addition, the effect after surgery may vary depending on individual differences, and a small number of patients may have postoperative diplopia or decreased vision.
Therefore, before receiving half femtosecond surgery, patients should be fully evaluated and consulted to understand the risks and expected effects of surgery. At the same time, selecting a regular hospital and an experienced doctor for surgery is also an important factor to ensure the success of the operation.
Applicable population and precautions
Half femtosecond surgery is applicable to myopic patients to a certain extent. Generally, myopic patients with diopter between -1.00D and -8.00D can consider this surgery. However, half femtosecond surgery is not suitable for patients with high myopic diopter or other eye diseases.
Before the half femtosecond surgery, the patient should have an eye examination to ensure that there is no other disease or infection in the eye. In addition, patients should also follow the doctor's postoperative care guidance to avoid strenuous exercise and contact with eye irritants, so as to reduce the risk of surgery and promote postoperative recovery.
Summary
Half femtosecond surgery in Kunming Hospital is an effective method to treat myopia. Changing the shape of the cornea through laser technology can significantly improve vision problems and reduce dependence on glasses or contact lenses. However, surgery also has certain risks. Before accepting surgery, patients should fully understand the effects and risks of surgery, and choose a regular hospital and doctor for surgery. In addition, patients should follow the guidance of doctors after the operation and carry out appropriate nursing and rehabilitation to ensure the stability and durability of the operation effect.
