Process of full femtosecond surgery in Hong Kong hospital
Femtosecond LASIK is an increasingly popular vision correction surgery in Hong Kong in recent years, and is widely recognized as one of the safest and most effective methods for myopia treatment. Hong Kong hospitals generally provide full femtosecond surgery, and continue to innovate and improve in the surgical process, equipment technology, and postoperative care to provide patients with high-quality vision correction services.
Surgical preparation
Before the full femtosecond surgery, Hong Kong hospitals will require patients to have a comprehensive eye examination to ensure that patients are suitable for surgery. These examinations include intraocular pressure, corneal measurement, corneal topography and other items. The doctor will evaluate the operation risk of the patient according to the examination results, and explain the operation process and postoperative precautions for the patient.
On the day of operation, the patient needs to stop wearing contact lenses and receive local anesthesia. Anesthetic eyedrops will be dropped into the patient's eyes to relieve the patient's discomfort.
Before entering the operating room, patients will wear surgical caps, masks and shoe covers to ensure that the operating environment is clean and sterile. Doctors and nurses will also wear appropriate protective clothing and gloves.
Operation process
In full femtosecond surgery, doctors will use a high-precision laser instrument to perform surgery. The surgical instrument can accurately cut the cornea and correct myopia by emitting nanosecond laser pulses. The whole procedure usually takes only a few minutes.
First, doctors will use a laser to create an extremely thin corneal flap on the cornea. This process is often referred to as "corneal flap fabrication". Later, the doctor will turn up the corneal flap so that the laser can directly act on the surface of the eye.
Next, the doctor will adjust the laser instrument according to the actual situation of the patient, and peel the tissue layer by layer on the cornea through the laser pulse. This process is often referred to as "tissue cutting". The patient will not feel any pain during the operation. At most, there will be some slight pressure on the eyes.
When the tissue is cut, the doctor will put the corneal flap back to its original position and wait for its natural bonding. Without suturing, the corneal flap will soon self firm and adapt to the new shape.
Postoperative care
Hong Kong Hospital attaches great importance to nursing and reexamination after full femtosecond surgery. The patient will be asked to take a rest for a period of time on the day of operation and give detailed postoperative guidance. The doctor will tell the patient how to use the eye properly, how to drop eye drops correctly, and provide some suggestions on eye protection measures.
One or two days after the operation, the patient needs to go to the hospital for reexamination. The doctor will carefully check the eye condition and further treat the patient as needed.
The recovery period after full femtosecond surgery usually lasts about a week. During this period, patients need to avoid strenuous exercise, overuse of eyes, squatting and other movements to avoid unnecessary irritation to the eyes. About one month after the operation, the patient's vision will reach a relatively stable level, and can resume normal life and work.
summary
The full femtosecond surgery provided by Hong Kong Hospital is a safe and effective myopia correction surgery. The operation process includes operation preparation, operation process and postoperative care. Full femtosecond surgery has been widely recognized and welcomed for its excellent results and short recovery period.
Although full femtosecond surgery is generally feasible in hospitals in Hong Kong, patients still need to carefully consider the reputation of the hospital, the experience of doctors, and the advanced level of equipment when choosing a surgical hospital. Only formal and professional hospitals and doctors can ensure the safety and effect of the operation.
