Risk and complications of femtosecond surgery in Nanjing Drum Tower Hospital
Nanjing Gulou Hospital is a well-known ophthalmic hospital, which provides advanced ophthalmic technology and surgery. Among them, femtosecond surgery is a common laser refractive surgery, which is used to correct myopia and astigmatism. Although femtosecond surgery has achieved remarkable results in correcting vision problems, it also has some risks and complications. This article will elaborate on the risks and complications of femtosecond surgery in Nanjing Drum Tower Hospital from the aspects of preoperative preparation, surgical process, postoperative recovery and long-term effects.
Risk and complications of preoperative preparation
Before the femtosecond surgery, the doctor will conduct a comprehensive eye examination to assess the feasibility of the surgery and the patient's eye health. However, some potential risks and complications may still occur in the preoperative stage. For example, if a patient has diabetes or other serious eye disease, surgery may be delayed or prohibited. In addition, fundus examination before surgery may cause eye discomfort or maladjustment.
In addition, patients need to follow the doctor's preoperative instructions and properly prepare for surgery. Failure to follow the doctor's advice or the diet taboo before surgery may lead to complications. Therefore, the risks and complications of preoperative preparation mainly include patients' personal reasons and evaluation of surgical suitability.
Risk and complications during operation
Femtosecond surgery is a delicate laser surgery, in which a laser is used to reshape the cornea. Although this technology is safe and reliable, there are still some risks and complications. The possible risks during the operation include infection, corneal whitening, corneal opacity, postoperative corneal edema, etc.
Complications during operation may be caused by inaccurate laser operation or individual differences of patients. Incorrect laser operation may lead to over cutting or insufficient cornea, thus affecting the surgical effect. Individual differences of patients may also lead to complications during the operation, such as postoperative pain, dry eyes, and vision discomfort.
Risk and complications of postoperative recovery
After femtosecond surgery, patients need to follow the doctor's instructions for postoperative care and recovery. Although most patients recover quickly after surgery, there are still some risks and complications.
Some possible risks after surgery include infection, dry eyes, vision fluctuation, etc. To avoid the risk of infection, patients need to wash their eyes regularly and use anti infection drugs recommended by doctors. Dry eyes can be relieved by using artificial tears. Vision fluctuation is a common temporary phenomenon after surgery, which usually recovers itself within a few weeks.
Risk and complications of long-term effects
The long-term effect of femtosecond surgery can last for many years, but there is no 100% success rate. Some patients may experience vision regression after surgery. Due to individual differences and changes in eye health, postoperative vision may fluctuate in a few years, or even require a second operation.
In addition, femtosecond surgery will not completely eliminate the risk of eye diseases. Patients still need regular reexamination and eye protection after surgery. Femtosecond surgery is not applicable to everyone. According to the doctor's assessment, it may be necessary to choose other surgical methods to correct vision problems.
Summary
As a common ophthalmic operation, femtosecond surgery in Nanjing Drum Tower Hospital has significant effect in correcting vision problems, but there are still some risks and complications. The risks and complications in the preoperative preparation stage are mainly related to the individual differences of patients and the feasibility of surgery. The possible complications during the operation are mainly related to the inaccuracy of laser operation and individual differences of patients. The risks and complications in the postoperative recovery stage involve infection, dry eyes and vision fluctuation. The risks and complications of long-term effects mainly include vision regression and changes in eye health. Therefore, when considering femtosecond surgery, patients should understand the related risks and complications in detail and make decisions under the guidance of doctors.
