Pain level of femtosecond surgery

Femtosecond surgery is an ophthalmic surgery used to correct myopia, hyperopia and astigmatism. Compared with traditional laser surgery, femtosecond surgery has less pain. The following will be detailed from four aspects: preoperative preparation, surgical process, postoperative pain and comparison with traditional surgery.

Preoperative preparation

Before femtosecond surgery, the doctor will conduct a comprehensive eye examination to assess whether the patient is suitable for surgery. This includes the measurement of corneal curvature, corneal thickness and axial length. Generally speaking, surgery can only be considered if the patient's vision is stable and there are no other eye diseases.

Before the operation, the doctor will explain the specific process and possible risks of the operation in detail to help the patient make a wise decision. In addition, the doctor will ask the patient to stop wearing contact lenses for a period of time so that the cornea can return to normal.

Operation process

Femtosecond surgery uses femtosecond lasers to precisely excite corneal tissue to change its shape and correct vision problems. The operation is usually performed under local anesthesia, and the patient will not feel any pain during the operation.

During surgery, doctors will use light pulses generated by femtosecond lasers to create a corneal flap with controllable depth and shape. Then, the doctor will gently fold the corneal flap to one side and use the laser to correct the problem in the central area of the cornea. The whole process usually takes only a few minutes.

Postoperative pain

Compared with traditional laser surgery, femtosecond surgery has less postoperative pain. Within a few hours after the operation, the patient may feel some discomfort and tingling, but the pain will soon disappear. Doctors usually prescribe some eyedrops to relieve the discomfort of patients according to their conditions.

Within a few days after the operation, the patient may feel that his eyes are more tired than usual and have a slight dry feeling. This is normal. You can relieve discomfort by closing your eyes more and using artificial tears. Most patients returned to normal life and work within one week after the operation.

Recovery time of femtosecond surgery

The recovery time of femtosecond surgery varies from individual to individual, but most patients can recover normal vision within a few days to weeks after surgery. The following is a detailed description of postoperative glasses, vision recovery and daily life.

Postoperative glasses

After femtosecond surgery, patients may need to wear special goggles for a period of time to protect the eyes and speed up the healing process. These goggles usually need to be worn during the day and can be removed at night. The doctor will determine the wearing time and method according to the specific situation of the patient.

As the cornea heals, the degree of the patient's glasses will gradually decrease. Usually after a few months, the patient can completely give up glasses and return to normal vision.

Visual acuity recovery

The visual recovery time of femtosecond surgery will vary with individual differences and different surgical methods. Most patients can feel a significant improvement in their vision on the first day after surgery, but some may need several days or weeks to fully recover.

Most patients can achieve good vision within one week after surgery. However, it may take longer to fully adapt to the new vision, especially in the case of binocular surgery.

daily life

After femtosecond surgery, patients need to follow the doctor's advice and precautions to speed up the recovery process. Within a few days after surgery, patients should try to avoid strenuous exercise and eye collision to avoid unnecessary irritation to the eyes.

In addition, patients should also avoid eye fatigue and dryness, and try to avoid staring at computers, mobile phones and other electronic screens for a long time. When you are outdoors, you should wear sunglasses to avoid the damage of ultraviolet rays to your eyes.

summary

Femtosecond surgery is a modern ophthalmic surgery with less pain and fast recovery time. Preoperative preparation includes eye examination and detailed explanation of operation contents; The patient will not feel pain during the operation; Postoperative pain is mild, but may be accompanied by eye fatigue and dryness; The recovery time varies from individual to individual. Most patients can recover normal vision within a few days to weeks after surgery.

In a word, femtosecond surgery is a safe and effective vision correction surgery, which can help patients get rid of the shackles of glasses and contact lenses and improve their quality of life.
