Is femtosecond laser surgery suitable for all myopia patients
As a professional ophthalmic hospital, Chengdu Huasha Eye Hospital has many experienced ophthalmologists, including the expert team of femtosecond laser surgery. However, whether femtosecond laser surgery is suitable for all myopia patients is a matter of great concern. Next, we will elaborate on the scope of application, surgical risks, effect durability and postoperative precautions.
Scope of application
First of all, we need to clarify which myopic patients are suitable for femtosecond laser surgery. Femtosecond laser surgery is mainly used to correct myopia, including mild, moderate and partial high myopia. However, for patients with high myopia whose diopter exceeds - 8D, the effect of femtosecond laser surgery may be limited, or other forms of surgery may be required to achieve the ideal correction effect.
In addition, femtosecond laser surgery is also applicable to healthy people between the ages of 18 and 50. For people over 50 years of age, due to the decline of intraocular lens function, other surgical methods may need to be considered. Femtosecond laser surgery may not be suitable for patients with other eye diseases (such as glaucoma, cataract, etc.).
Therefore, before deciding whether to perform femtosecond laser surgery, the patient needs to conduct a detailed ophthalmic examination to determine its scope of application.
Surgical risk
Femtosecond laser surgery is relatively safe, but it does not mean that there is no risk. Preoperative evaluation is one of the important steps to reduce the risk of surgery. According to the individual condition of the patient, the possible risks of femtosecond laser surgery include eye infection, corneal edema, inflammation, dry eyes, etc.
In addition, because of the different corneal morphology and physiological characteristics of each patient, the risk of surgery is also different. Therefore, before femtosecond laser surgery, doctors will conduct a detailed examination of the patient's cornea to assess the feasibility and risk of surgery.
Effect durability
The effect durability of femtosecond laser surgery is one of the focuses of patients. According to the existing clinical research data, the correction effect of femtosecond laser surgery on myopia is lasting, which can be maintained for several years or even longer. However, individual differences exist, so the effect of each patient cannot be guaranteed to be completely lasting.
In addition, some patients may have postoperative clarity or recurrence, which is related to individual corneal healing and compliance with postoperative precautions. Therefore, in order to maintain the durability of the surgical effect, patients need to actively cooperate with doctors in postoperative management and regular review.
Postoperative precautions
After femtosecond laser surgery, patients need to pay attention to some matters. First of all, the patient needs to avoid eye collision and abrasion, so as not to affect corneal healing. Secondly, in a period of time after surgery, patients need to follow the doctor's medication guidance, use eye drops on time, and reduce infection and other complications.
In addition, patients should also pay attention to keeping their eyes clean and avoid using irritating cosmetics and eyedrops to avoid adverse reactions. For patients who are engaged in special occupations or hobbies, doctors will also give corresponding suggestions to avoid eye injuries.
Summary
In conclusion, femtosecond laser surgery is not suitable for all myopia patients. The key factors to determine whether femtosecond laser surgery is suitable for patients are the scope of application, surgical risk, effect durability and postoperative precautions. Before deciding to perform femtosecond laser surgery, patients should have detailed consultation and eye examination with ophthalmologists to ensure the safety and efficacy of the surgery.
