Introduction of femtosecond ophthalmic surgery in Zhongshan Second Hospital, Guangzhou
The Department of Ophthalmology of Guangzhou Zhongshan Second Hospital is a branch of Zhongshan Central Hospital in Zhongshan City, Guangdong Province. It has advanced equipment and technology to provide patients with high-quality ophthalmic services. Among them, ophthalmic femtosecond surgery is an important technology of the hospital.
Femtosecond laser surgery is one of the most advanced refractive surgery in the field of ophthalmology. As a leader in the medical field, the ophthalmology department of Guangzhou Zhongshan Second Hospital has introduced and mastered this technology. The surgery removes a layer of corneal epithelium through laser, and then reshapes the corneal curvature to correct vision problems such as myopia, hyperopia and astigmatism. Compared with traditional laser surgery, femtosecond laser surgery is more accurate and safe.
Necessity to stop wearing contact lenses
Before the femtosecond ophthalmic surgery, the ophthalmologist of Guangzhou Zhongshan Second Hospital will ask the patient to stop wearing contact lenses for a period of time. This is mainly to ensure the safety and effect of the operation.
First of all, wearing contact lenses will lead to changes in corneal morphology, making the preoperative corneal measurement inaccurate. Femtosecond laser surgery requires accurate measurement of the shape and thickness of the cornea. If the patient still wears contact lenses before surgery, the measurement results may be inaccurate, which will affect the surgical effect.
In addition, contact lenses may cause some eye diseases, such as keratitis, corneal ulcer, etc. These eye diseases may increase the risk of surgery, so stopping wearing contact lenses for a period of time can help patients recover their eye conditions and reduce the risk of surgery.
To sum up, it is necessary to stop wearing contact lenses for ophthalmic femtosecond surgery, which can ensure the accuracy and safety of surgery.
Time to stop wearing contact lenses
In the ophthalmology department of Zhongshan Second Hospital in Guangzhou, doctors usually ask patients to stop wearing contact lenses for a certain time before surgery. The specific length of stopping time will depend on the individual condition of the patient.
Generally, patients need to stop wearing hard contact lenses for at least 2 to 4 weeks, and stop wearing soft contact lenses for at least 1 to 2 weeks. This is because hard contact lenses have been used for a long time and have a more obvious impact on the cornea, requiring a longer recovery time. Soft contact lenses, however, have a relatively short use time, have a relatively light impact on the cornea, and require a relatively short recovery time.
In addition, the doctor will make a detailed assessment based on the patient's individual conditions and eye examination results to determine the most appropriate time to stop wearing. Therefore, before undergoing ophthalmic femtosecond surgery, patients need to stop wearing contact lenses in strict accordance with the doctor's recommendations.
Resume wearing contact lenses after surgery
After the femtosecond ophthalmic surgery, the ophthalmologist of Guangzhou Zhongshan Second Hospital will decide when to resume wearing contact lenses according to the patient's operation and recovery progress.
Usually, patients can use eyedrops and blackout glasses on the first day after surgery, and do not need to wear glasses or contact lenses. The doctor will visit again regularly to observe the patient's eye condition and decide when to resume wearing contact lenses according to the recovery.
However, for some patients, the corneal morphology after surgery may change to a certain extent, leading to the original way of wearing no longer applicable. In this case, the doctor will re measure the corneal curvature and glasses matching degree according to the specific situation of the patient, and adjust new contact lenses for them.
conclusion
It is necessary to stop wearing contact lenses before the femtosecond operation in the ophthalmology department of Zhongshan Second Hospital in Guangzhou, which can ensure the safety and effect of the operation. The specific stop time will depend on the individual condition of the patient, and the recovery of wearing contact lenses after surgery will depend on the recovery of the patient. By effectively managing the time of wearing contact lenses, the success and effect of femtosecond surgery can be ensured to the greatest extent. The ophthalmology department of Guangzhou Zhongshan Second Hospital has rich experience and authoritative technology in this field, so patients can safely choose this hospital for ophthalmic femtosecond surgery.
