Guangzhou All Femtosecond Hospital: What are the sequelae of all femtosecond surgery?
Full femtosecond surgery is a kind of laser vision correction surgery, which has attracted more and more attention in Guangzhou in recent years. Although full femtosecond surgery is considered to be a relatively safe and effective method for vision correction, there are still some potential sequelae. The sequelae of full femtosecond surgery will be described in detail from four aspects below.
Postoperative xerophthalmia
Postoperative xerophthalmia is one of the common sequelae of full femtosecond surgery. As the laser cuts the cornea during the operation, the nerves and blood vessels on the cut surface may be damaged, resulting in dryness and discomfort of the eyes after the operation. Some patients may suffer from dryness, pain, burning, red eyes and other symptoms several days or even weeks after surgery. Normally, doctors will provide patients with artificial tears to alleviate these symptoms. The symptoms of most patients will relieve themselves within a few months.
However, for individual patients, postoperative dry eye may last for a long time and seriously affect their quality of life. These patients may need long-term use of artificial tears or other treatments to alleviate dry eye symptoms. Therefore, when considering full femtosecond surgery, patients must understand the potential risk of dry eye and fully communicate and discuss with doctors.
Unstable vision recovery
Full femtosecond surgery has a significant effect in correcting myopia, hyperopia and astigmatism. Most patients can obtain significant vision improvement after surgery. However, some patients may experience unstable vision recovery within a few months after surgery. This is because corneal tissue needs a period of time to heal and stabilize after surgery, and individual differences and the predictability of treatment results may also have a certain impact on vision recovery.
For patients with unstable vision recovery, it is often necessary to monitor vision changes through regular follow-up visits and eye examinations, and make necessary adjustments as needed. Only after the cornea is completely healed and stabilized, the doctor will determine the final correction effect.
Postoperative keratitis
Postoperative keratitis is a potential sequela of all femtosecond surgery. During the operation, a corneal flap needs to be formed on the cornea, which may cause bacterial infection on the cornea. Postoperative keratitis may lead to decreased vision, red eyes, eye pain and increased secretion.
In order to reduce the risk of postoperative keratitis, doctors usually carry out detailed eye examinations and relevant preoperative preparations for patients. After surgery, patients need to strictly follow the doctor's postoperative nursing guidance, including the use of antibiotic eye drops, avoiding eye rubs, etc. In case of any abnormal symptoms, seek medical advice in time and receive further treatment from the doctor.
Postoperative changes of corneal structure
Laser ablation of cornea in full femtosecond surgery may cause structural changes of cornea. The cornea may become thinner after surgery, and corneal thickness is closely related to eye health. Some patients may have symptoms such as corneal deformation, corneal pain or corneal disease aggravation.
Because of the risk of corneal structural changes after surgery, doctors will pay special attention to the patient's corneal health when evaluating the applicability of full femtosecond surgery. For those patients who have corneal diseases or thin corneas, doctors may recommend other corrective methods or not recommend surgery.
Summary
Although full femtosecond surgery is a safe and effective method for vision correction, there are still some potential sequelae. Postoperative xerophthalmia, unstable vision recovery, postoperative keratitis and corneal structural changes are common sequelae of full femtosecond surgery. Therefore, before considering full femtosecond surgery, patients need to fully communicate and discuss with doctors to understand the potential risks and consequences of surgery. At the same time, it is very important to follow the doctor's postoperative nursing advice and return regularly for the best management and solution of these sequelae.
