How to choose a suitable femtosecond surgery method?
The eye is one of the most important sensory organs in our body, so it is very important to choose the appropriate surgical method when deciding to perform laser myopia surgery. Lanzhou Femtosecond Hospital, as a professional ophthalmic hospital, provides patients with a variety of femtosecond surgery methods, so that each patient can choose their own surgery method.
Operation mode 1: LASIK
1. Operation principle:
LASIK surgery is to change the shape of cornea by laser cutting corneal tissue, so as to achieve the effect of correcting myopia. The corneal tissue is cut to change its shape and focus light on the retina to reduce myopia.
2. Applicable population:
LASIK is suitable for myopia, hyperopia and astigmatism patients, but the correction effect for astigmatism patients is relatively weak. The patient must be 18 years old, with stable eye health, and meet the minimum corneal thickness and other relevant indicators.
3. Surgical advantages:
LASIK has the advantages of short operation time, fast recovery and stable correction effect. The patient's vision will recover quickly after surgery, and it usually takes a few days to a month to gradually stabilize. After the operation, there is no need to be hospitalized for observation, just regular follow-up.
Operation mode 2: PRK
1. Operation principle:
PRK removes epidermal cells by laser, and then uses laser to etch the cornea to change the shape of the cornea and achieve the effect of correcting vision. Compared with LASIK, PRK does not need to make corneal flap, which protects the integrity of the cornea.
2. Applicable population:
PRK is suitable for patients with unstable vision, thin cornea and high myopia. The patient must be 18 years old, with stable eye health, and meet the minimum corneal thickness and other relevant indicators.
3. Surgical advantages:
The advantage of PRK surgery is that it is less invasive to the cornea, and it is especially suitable for people engaged in high myopia after surgery. After surgery, new epithelium needs to grow on the corneal surface, so the vision recovery process is slower than LASIK.
Operation mode 3: ReLEx SMILE
1. Operation principle:
ReLEx SMILE surgery is to directly create a 3-4mm micro incision in the cornea by laser, and then remove the corneal tissue in the cornea to change the shape of the cornea, thus correcting myopia. The whole process does not need to make corneal flap.
2. Applicable population:
ReLEx SMILE surgery is suitable for patients with diopter between - 1.0 and - 10.0, thin corneal thickness and large corneal radian. The patient should be 18 years old, and the eye health should be stable and meet the relevant indicators.
3. Surgical advantages:
ReLEx SMILE surgery has the advantages of less trauma and less postoperative dry eye. During the operation, only one incision is needed to complete the operation. The postoperative vision recovers quickly, and the incidence of dry eye is also low.
Operation mode 4: ICL
1. Operation principle:
ICL (Implantable Collier Lens) surgery is to implant a customized ICL into the eye to change the visual condition of the eye. ICL surgery does not change the shape of the cornea, but changes the ocular diopter by implanting lenses.
2. Applicable population:
ICL surgery is suitable for patients with high myopia, cornea not suitable for laser surgery or poor laser surgery effect. The patient should be over 18 years old, and the eye health should be stable and meet the relevant indicators.
3. Surgical advantages:
The advantage of ICL surgery is that it can correct high myopia without changing the shape of the cornea, and it can restore the natural physiological state of the eyeball after surgery. The operation process does not need to cut corneal tissue, and the lens implantation process is short and safe.
Summary:
Lanzhou Femtosecond Hospital provides patients with a variety of femtosecond surgery methods suitable for different populations, including LASIK, PRK, ReLEx SMILE and ICL. Patients should consider their own eye health, age, myopia degree and other factors when choosing the operation mode, and make decisions under the guidance of doctors. By choosing a suitable surgical method, the patient can obtain a stable correction effect and a good postoperative recovery effect.
