Can myopic patients obtain curative effect through fundus laser surgery?
Fundus laser surgery is a method developed in recent years to treat myopia. It corrects the fundus by laser to achieve lasting improvement of vision. In Guangzhou Zhongshan Ophthalmology Department, this operation has been widely used and has achieved certain curative effect. This article will elaborate the curative effect of fundus laser surgery from four aspects: operation principle, operation effect, operation risk and postoperative precautions.
Operation principle
Fundus laser surgery is to use laser to correct the retina of the fundus and improve vision by changing the diopter. This operation uses excimer laser technology to carve tiny dots on the retina to change the refraction angle of light, so as to correct myopia. Because of the fine operation, small incision and fast recovery, it is welcomed by myopic patients.
The principle of fundus laser surgery is relatively complex. Before surgery, a detailed fundus examination is required to determine the surgical method and treatment plan. During the operation, the patient needs to inject anesthetic drugs to ensure painless and comfortable operation. The whole operation process usually takes only a few minutes, and patients need to follow the doctor's instructions for recovery care after the operation.
Surgical effect
According to the statistical data of Zhongshan Ophthalmology Department in Guangzhou, fundus laser surgery has achieved good results in myopia correction. After the operation, the eye degree of most patients decreased significantly, and their vision improved significantly. However, the durability of the surgical effect varies from person to person, and some patients may need multiple operations to achieve the desired effect.
It is worth noting that fundus laser surgery has different effects on different degrees of myopia. Generally speaking, mild and moderate myopia patients have better surgical results, while severe myopia patients may need multiple operations to achieve ideal results due to their high diopter.
Surgical risk
Fundus laser surgery is a relatively safe operation, but there are still some risks. After the operation, there may be some uncomfortable feelings such as blurred vision, dryness and eye pain. Most of these symptoms will disappear within weeks after the operation. A small number of patients may have surgical complications, such as elevated intraocular pressure and infection, but the incidence is low.
Therefore, before deciding to accept fundus laser surgery, patients need to fully understand the risks of surgery, and have a detailed discussion and communication with doctors.
Postoperative precautions
After fundus laser surgery, patients need to follow the doctor's postoperative nursing guidance. First of all, patients need to ensure eye hygiene after surgery to avoid infection. At the same time, antibiotic eyedrops and anti-inflammatory drugs should be used according to the doctor's requirements to promote wound healing. In addition, excessive eye use and strenuous exercise should be avoided after surgery to avoid unnecessary irritation and injury to the eyes.
In order to ensure the durability of the surgical effect, regular review and testing after surgery are essential. Patients need to follow the doctor's reexamination arrangements and report any abnormal symptoms to the doctor in time.
Summary
To sum up, fundus laser surgery is an effective method to treat myopia. In Guangzhou Zhongshan Ophthalmology Department, fundus laser surgery has been widely used and has achieved good results. The operation principle is based on the laser correction of the retina. The operation effect varies from individual to individual, but most patients can be significantly improved. The risk of surgery is low, but patients still need to fully understand and communicate with doctors before surgery. Postoperative care, regular reexamination and testing are crucial to the durability of the surgical effect.
