Full femtosecond surgery in Nanjing First Hospital: risks and side effects
The full femtosecond surgery is a popular ophthalmic surgery in Nanjing First Hospital in recent years. It corrects the refractive error of the eye through laser technology, so that patients can get rid of the shackles of glasses or contact lenses. However, like all operations, full femtosecond surgery also has certain risks and side effects. This article will elaborate on preoperative preparation, surgical process, postoperative recovery and complications.
Preoperative preparation
Before the full femtosecond surgery, patients need to undergo a comprehensive eye examination to ensure the adaptability and safety of the surgery. These examinations include fundus optometry, intraocular pressure measurement and corneal morphology measurement. Some patients may not be suitable for full femtosecond surgery because of high myopia or other eye diseases. Therefore, before determining that surgery can be performed, doctors need to fully assess the patient's eye health.
In addition, the preoperative preparation stage also includes informing patients about the risks and side effects of the operation. Although full femtosecond surgery is considered to be a safe and effective surgical method, there are still some risks, such as infection, xerophthalmia and poor visual effect. Doctors should explain these risks to patients in detail to ensure that patients can make wise decisions.
Operation process
The full femtosecond surgery usually takes about 20 minutes to complete. The surgery process is divided into two steps: making flap layer and laser correction. In the stage of making valve layer, the patient needs to fix his head on the operating table and inject local anesthetic. Then, the doctor used a femtosecond laser to make a flap with a diameter of about 8-9mm on the cornea. Next, the doctor lifted the flap and used a laser to correct the exposed cornea.
The possible risks during the operation include eye movement, corneal infection and scratches. In order to mitigate these risks, doctors need to keep their hands stable and ensure that the laser beam is accurately aimed at the target area. At the same time, intraoperative instruments and equipment should be strictly sterilized and maintained to prevent infection.
Postoperative recovery
After the full femtosecond surgery, the patient needs to rest in the hospital for a while to ensure that the eyes are stable and comfortable. The doctor will give some suggestions to the patient, such as avoiding rubbing eyes, paying attention to diet and protection, and following medication instructions. In the next few days or weeks, patients may have blurred vision, photosensitivity, increased tears and other symptoms, which are normal postoperative reactions and generally disappear.
However, there are still some risks and side effects during postoperative recovery. Possible complications include infection, corneal flap displacement, inflammatory reaction and dry eye. Therefore, during the recovery period after surgery, patients need to visit again regularly, so that doctors can conduct a comprehensive examination of the eyes, and find and deal with any problems in a timely manner.
Summary
In general, the full femtosecond surgery in Nanjing First Hospital is a safe and effective ophthalmic corrective surgery. However, there are certain risks and side effects in preoperative preparation, surgical process, postoperative recovery and complications. Before deciding to accept full femtosecond surgery, patients should fully communicate with doctors, understand the risks and side effects of surgery, and evaluate their adaptability. In addition, during the recovery period after surgery, patients need to strictly follow the doctor's guidance and return regularly to ensure the effect of surgery and eye health.
