Is New Vision Surgery more suitable for myopia or hyperopia in Shanghai Eye Hospital?
The development of ophthalmic surgery provides new options for vision correction, including the increasingly popular new vision surgery in recent years. No matter myopia or hyperopia, the new vision surgery can provide an effective correction scheme. However, in Shanghai Eye Hospital, there are some differences in the applicability of the new vision surgery for patients with different diopters. This article will elaborate the applicability of the new vision surgery to myopia and hyperopia in Shanghai Eye Hospital from four aspects: the principle of surgery, postoperative effects, surgical risks and patient selection.
1. Operation principle
The new vision surgery uses laser correction technology to correct vision by changing the corneal diopter. For myopic patients, the operation mainly involves over cutting the central area of the cornea to reduce the corneal refractive power and correct the patients' far vision. For hyperopia patients, the surgery is to increase the diopter at the edge of the cornea to correct hyperopia. Due to the difference in surgical principles, the New Vision Surgery is more suitable for myopia than hyperopia in Shanghai Eye Hospital.
However, the operation plan should also be determined according to the specific situation of the patient. Some hyperopia patients may have abnormal corneal morphology or low diopter, which may affect the effect of surgery. Therefore, when determining the applicability of surgery, doctors will comprehensively consider the principles of surgery and individual differences of patients.
2. Postoperative effect
The new vision surgery in Shanghai Eye Hospital has a stable postoperative effect on myopia patients. In the short term, most patients can significantly improve their vision after surgery, reaching or approaching the normal level. In the long run, after a period of rehabilitation, the degree of myopia remains at a low level. However, for patients with hyperopia, the postoperative effect may be relatively poor due to the differences in surgical principles and the particularity of hyperopia.
For some patients with a high degree of hyperopia, surgery can only partially correct vision, and can not completely get rid of glasses or contact lenses. Therefore, in Shanghai Eye Hospital, doctors usually make a detailed preoperative assessment of hyperopia patients and give reasonable expectations for surgery according to the patient's situation.
3. Operation risk
There are some differences in the risk of new vision surgery for myopia and hyperopia patients. For myopic patients, new vision surgery is usually a safer choice. After years of development and improvement, the laser technology used in the operation has a relatively low risk. However, there are still some patients who may have common surgical risks such as dry eye and postoperative vision fluctuation.
However, for patients with hyperopia, the risk of surgery is relatively high due to more technical operations and more accurate laser control required for corneal edge cutting. Postoperative discomfort such as incomplete correction of preoperative degree, light interference or glare may occur. Therefore, in Shanghai Eye Hospital, doctors will be more careful to assess the surgical risk of hyperopia patients.
4. Patient selection
In Shanghai Eye Hospital, the choice of patients will also have an impact on the applicability of the new vision surgery. Generally speaking, patients with myopia between - 1.0 and - 10.0 are most suitable for new vision surgery. In addition, the patient must be at least 18 years old, and the eye degree is stable, that is, there is no obvious change in vision in the past year. For patients with hyperopia, the conditions for choosing a new vision surgery are relatively harsh, so doctors usually recommend them to choose other correction methods.
Summary
In general, the new vision surgery is more suitable for myopia than hyperopia in Shanghai Eye Hospital. The operation principle, postoperative effect, operation risk and patient selection make the new vision surgery more advantageous for myopia correction. However, for patients with hyperopia, the new vision surgery may have poor postoperative effect and high surgical risk, so doctors usually choose other correction methods at their discretion.
