Introduction to all femtosecond surgery
As a well-known medical institution, Guangzhou Grand Hospital has introduced and promoted the full femtosecond surgery technology to provide patients with a safer and more accurate myopia treatment scheme. Full femtosecond surgery is an advanced corneal refractive surgery, which uses laser technology to thin and correct the surface of the cornea to correct vision. However, although full femtosecond surgery has significant effects in the field of myopia treatment, it is not without risks. The risks of full femtosecond surgery will be described in detail below.
Preoperative risk assessment
Before deciding whether to perform full femtosecond surgery, the doctor will conduct a comprehensive assessment of the patient's eye condition. However, even after detailed evaluation, the risk of postoperative complications cannot be completely excluded. The purpose of preoperative risk assessment is to reduce the probability of complications as much as possible, but it is still unable to completely eliminate the risk.
First, full femtosecond surgery may pose a risk of wound infection. Although the aseptic environment of the ward is strictly controlled during the operation, the infection problem after the operation may still be caused due to individual differences, improper operation and other factors.
Secondly, full femtosecond surgery may cause corneal tissue damage during the operation. The laser is required to thin and correct the cornea during the operation. If the thin process of corneal tissue during the operation is not accurate enough, it may lead to problems such as corneal irregularity and excessive corneal thinning.
Finally, full femtosecond surgery may affect postoperative visual stability. Corneal refractive power is one of the important factors to maintain normal vision. After surgery, due to changes in the cornea that may lead to fluctuations and instability in vision, additional treatment and adjustment may be required.
Surgical risk
In addition to preoperative risk assessment, full femtosecond surgery itself has certain risks.
First, elevated intraocular pressure may occur during surgery. The laser treatment process will generate some heat and exert pressure on the eyeball, which may lead to the rise of intraocular pressure. Although doctors can control the output of laser energy, there is still a risk of elevated intraocular pressure.
Secondly, corneal pain or discomfort may occur during surgery. Because the operation needs to be performed on the surface of the eyeball during the operation, it may cause corneal pain or discomfort, especially for postoperative patients, this pain may last for a period of time.
Finally, glare or blurred vision may occur during surgery. This is because the laser is required to cut and correct the cornea during the operation, and the light and energy generated during the operation may stimulate the eyes, resulting in blurred vision or glare for a period of time.
Postoperative risks and suggestions
The postoperative risk of full femtosecond surgery needs patients' attention.
First, dry eye symptoms may occur after surgery. Because the cornea is cut and corrected during the operation, the balance of the cornea may be damaged, resulting in insufficient tears secreted by the eyes, thus causing dry eye symptoms. Patients need to pay attention to the use of artificial tears to moisten their eyes, and avoid behaviors that may lead to eye fatigue such as using electronic devices for a long time.
Secondly, corneal edema or infection may occur after surgery. Corneal edema may be caused by corneal tissue cutting and correction after surgery. If improper postoperative care or infection sources exist, infection may be caused. Therefore, patients need to use antibiotic eyedrops according to the doctor's recommendations and pay attention to postoperative care.
Finally, postoperative vision fluctuation and recurrence may occur. Although the surgical effect can often be maintained for a period of time, in the long run, the cornea may change over time, resulting in vision fluctuations and postoperative recurrence. Patients need to be reviewed regularly and follow the doctor's advice for additional treatment.
summary
As an advanced myopia treatment technology, full femtosecond surgery in Guangzhou University Hospital has significant effects, but there are still some risks. Preoperative risk assessment, surgical risk and postoperative risk all need patients' attention. Only when we fully understand the risks and accept the guidance of professional doctors can we reduce the probability of complications and ensure the safety and effectiveness of the operation.
