Risk of femtosecond laser surgery in Wuhan Union Medical College Hospital
With the continuous progress of science and technology, femtosecond laser surgery, as a common ophthalmic surgery technology, has been widely used in Wuhan Union Medical College Hospital. Femtosecond laser surgery has become an important method to treat eye diseases because of its high precision and high controllability. However, like any surgery, femtosecond laser surgery also has some risks. This article will elaborate on the risks of femtosecond laser surgery in Wuhan Union Medical College Hospital from four aspects: corneal injury, infection risk, postoperative complications and uncertainty of surgical effect.
Risk of corneal layer injury
Femtosecond laser surgery is performed by passing the laser beam through the surface layer of the cornea, so there is a risk of corneal layer damage. Although femtosecond laser surgery is technically mature, there is still the possibility of thermal and photochemical damage to the cornea caused by laser beam penetrating the cornea. These injuries may lead to dry eyes, blurred vision and other uncomfortable symptoms after surgery.
In addition, due to individual differences and factors that cannot be completely controlled during the operation, such as corneal curvature, it may also lead to complications such as corneal layer incarceration and corneal epithelium shedding during the operation, increasing the risk of the operation.
Risk of infection
Although femtosecond laser surgery is a non-invasive operation, there is still a risk of infection. Inadequate preoperative preparation, cross infection during operation and other factors may increase the probability of infection. If infection occurs after surgery, patients may suffer from eye pain, vision loss and other symptoms, and even blindness in serious cases. Therefore, before femtosecond laser surgery, doctors need to conduct a comprehensive examination of the patient's eyes to ensure that the patient has no risk of infection.
Risk of postoperative complications
Femtosecond laser surgery may have some complications after surgery. Poor corneal epithelial healing after surgery may lead to vision fluctuations, blurred vision and other problems. The patient may also have dry eye symptoms, including dry eyes, pain, foreign body sensation, etc. In addition, corneal infection, corneal edema and other complications may also occur after surgery, seriously affecting the recovery of patients' vision.
In order to reduce these risks, patients need to strictly follow the doctor's postoperative care guidelines, such as using antibiotic eye drops to prevent infection and avoid eye injuries.
Risk of uncertainty of surgical effect
The recovery of vision after femtosecond laser surgery is not 100% guaranteed. Uncertainty of surgical effect is a risk of femtosecond laser surgery. Each patient's eye physiological structure and disease conditions are different, and the effect of postoperative vision recovery will also be different. Even if everything goes well during the operation, there may still be situations such as poor vision and inaccurate adjustment of corneal refractive state after the operation.
In conclusion, although the femtosecond laser surgery in Wuhan Union Medical College Hospital has achieved remarkable results in the treatment of eye diseases, there are still some risks. Before deciding to accept femtosecond laser surgery, patients should fully understand the risks and benefits of surgery and make decisions under the guidance of doctors. Postoperative patients need to be nursed and reexamined in strict accordance with the doctor's requirements to reduce risks and promote postoperative recovery.
summary
Femtosecond laser surgery is an ophthalmic surgery technique widely used in Wuhan Union Medical College Hospital in recent years. However, the operation also has certain risks. It includes the risk of corneal injury, infection, postoperative complications and uncertainty of surgical effect. Before deciding to accept the operation, patients should fully understand their risks and benefits, and make decisions under the guidance of doctors. Postoperative patients need to be nursed in strict accordance with the doctor's nursing guidelines to reduce risks and promote postoperative recovery.
