What operation is full femtosecond in Sichuan Provincial Hospital?
Full femtosecond surgery is a common ophthalmic surgery in Sichuan Provincial Hospital, which is used to correct refractive errors such as myopia, hyperopia and astigmatism. All femtosecond surgery uses laser technology to precisely cut and reshape the cornea to improve vision problems. The full femtosecond surgery will be described in detail in the following four aspects: operation principle, procedure, effect and risk.
Operation principle
All femtosecond surgery uses a technology called femtosecond laser. Femtosecond laser acts on corneal tissue through fast laser pulses, removing only the thin tissue layer without damaging other tissues, thus changing the curvature of the cornea to correct refractive errors. Compared with traditional laser surgery, this surgery has higher accuracy and safety.
In full femtosecond surgery, the cornea is first cut by femtosecond laser, and then the laser is used for optical leveling at the incision, and finally the cornea is naturally healed. The whole operation process is controlled by a computer, and doctors only need to operate a few devices, so the operation is faster and more accurate.
Procedure
Full femtosecond surgery is usually divided into four steps: pre operation examination, pre operation preparation, operation and post operation nursing.
In the pre operation examination, the doctor will make a comprehensive examination of the patient's eyes, including the ocular surface, corneal curvature, fundus, etc. Through the examination results, the doctor will develop a personalized surgical plan.
Preoperative preparation includes comprehensive preoperative communication and informed consent for patients, as well as preparation and commissioning of surgical equipment.
During the operation, the patient needs to lie flat on the operating table, and then the doctor will drop some anesthetic liquid on the surface of the eyeball, and then use a femtosecond laser to cut and reshape it. The operation time is usually very short, usually only a few minutes.
In the postoperative nursing stage, the doctor will give the patient antibiotic eye drops and eye anti-inflammatory drugs. Attention should be paid to avoid external impact on the eyes, and recheck should be carried out according to the doctor's requirements.
Operation effect and risk
The effect of full femtosecond surgery is remarkable, and patients can usually feel the obvious improvement of vision immediately after surgery. After surgery, most patients can no longer rely on glasses or contact lenses to regain good vision. The operation effect is durable and stable, which brings great convenience to the improvement of postoperative quality of life.
Although the technology of all femtosecond surgery is developing continuously, there are still some risks. Possible risks include dry eyes, infection, glare and night vision loss. However, the probability of these risks under standardized operation is low, and patients can make decisions according to their own conditions and doctors' suggestions.
Summary
All femtosecond surgery in Sichuan Provincial Hospital is an ophthalmic surgery that corrects vision problems through laser technology. This operation uses fast and accurate femtosecond laser to cut and reshape the cornea. The operation process is safe and fast, and patients can immediately feel the effect of significantly improved vision after the operation. Although there are certain risks, patients can ensure the safety and effectiveness of the operation by fully communicating with doctors and carrying out necessary pre-operative examinations.
