How many degrees of myopia can be corrected by Shanghai Eye Hospital New Vision?
Eye hospitals are medical institutions that provide diagnosis, treatment and surgery services for eye diseases. As a leading ophthalmic medical institution in China, Shanghai Eye Hospital has advanced technical equipment and an experienced expert team to provide patients with comprehensive ophthalmic health services. Among them, the new vision surgery is a common myopia correction surgery, so how much myopia can it correct? The following will be elaborated from different aspects.
Corneal condition
When ophthalmologists decide whether to perform a new vision surgery, they first need to check the patient's corneal condition. Cornea is one of the main causes of ametropia due to large curvature in myopia. In general, new vision surgery is mainly applicable to patients with myopia between -1.00 and -12.00. For patients with high myopia, ophthalmologists may consider other surgical methods, such as laser corneal correction.
In addition to the degree of myopia, the thickness and curvature of the cornea are also important factors to consider the surgical indication. Patients with sufficient corneal thickness and moderate curvature are more suitable for new vision surgery, because the surgery requires cutting on the cornea and laser correction. Therefore, ophthalmologists will comprehensively consider the patient's corneal condition to determine the feasibility of surgery.
Age requirements
Age is also an important factor affecting the indications of new vision surgery. In general, the new vision surgery is applicable to myopia patients between 18 and 45 years old. The eyes of patients in this age group develop stably, and the degree of myopia is relatively fixed. Premature surgery may lead to the increase of myopia again, while the cornea of older patients may be aging to some extent, which is not suitable for surgery.
Of course, not all patients between the ages of 18 and 45 years old meet the surgical conditions, which still needs to be judged according to individual conditions. Therefore, when deciding whether to perform a new vision surgery, it must be conducted under the guidance of a professional doctor and undergo a comprehensive examination and evaluation to ensure the safety and effectiveness of the surgery.
good health
Physical health is also one of the considerations of the surgical indications of New Vision. Patients with some systemic diseases or eye diseases may not be suitable for surgery, such as diabetes, keratitis, glaucoma, etc. In addition, pregnant and lactating women are not suitable for ophthalmic surgery. Therefore, when considering surgery, doctors will know the patient's medical history and physical condition in detail to ensure the safety of surgery.
individual difference
In addition to the above considerations, individual differences are also one of the important factors determining the surgical indications of the new vision. Everyone's eye structure, physiological characteristics and medical history are different, so the surgical effect will be different. Some people may completely get rid of glasses after surgery, while others may need to wear low-grade lenses for clearer vision.
In addition, postoperative recovery will vary from person to person. Some patients will return to normal vision within one or two days after surgery, while some patients may need more time. Therefore, before the new vision surgery, the doctor will conduct a comprehensive assessment of the patient's eyes, explain the surgical effect and risks in detail, and ensure that the patient has correct expectations for the surgery.
To sum up, the new vision surgery is suitable for patients with myopia between -1.00 and -12.00 and who meet the corneal conditions, age requirements and physical health conditions. However, everyone's eye condition is different, and the surgical effect and recovery time will also be different. Therefore, before the new vision surgery, it is necessary to find a professional ophthalmologist for comprehensive evaluation and consultation to ensure the safety and effectiveness of the surgery.
