1. The correction degree is different
Full femtosecond surgery : It can correct myopia within 1000 degrees and astigmatism within 500 degrees.
ICL crystal implantation : It can correct myopia within 1800 degrees and astigmatism within 600 degrees. It is suitable for myopia people with thin corneal, high myopia degree and high requirements for visual quality.
2. The principles of surgery are different
Full femtosecond surgery : "Subtraction" in myopia surgery
Full femtosecond laser scanning to make a corneal tissue diaphragm of the microlens, and make an incision above the cornea to remove the corneal tissue, which is equivalent to making a "pair of lenses" on the cornea to achieve the purpose of removing the mirror.
ICL crystal implantation : "addition" in the eyes
ICL surgery does not require cutting the cornea. It can place an intraocular lens tailored to the patient's eye condition behind the iris in the patient's eye to achieve the purpose of correcting vision.
3. Different surgical positions
Full femtosecond surgery : corneal stromal layer.
Surgery procedure: 1) Pointing the eye surface anesthesia eye drops—2) femtosecond laser scanning to make microlens—3) Femtosecond laser to make microincision—4) Separation and removal of corneal stromal lens—5) The operation is completed.
ICL Crystal Surgery Position: Between the iris and the lens.
Surgery procedure: 1) Point the eye surface anesthesia eye drops - 2) Make a small incision - 3) Inject gel into the eye, and inject ICL into the eye - 4) Adjust the ICL to the appropriate position and suck the gel out of the eye - 5) The operation is completed.
4. The preparation time is different
Full femtosecond surgery : 2-3 days
The first day of preoperative examination (1-2 hours), the second day of surgery + rest (all day), and the third day of re-examination (half hour).
ICL crystal implantation : 1 week-3 months
preoperative examination on the first day (3-4 hours), Swiss pre-order crystal (1 week-3 months), crystal arrives and arranges the operation time + 2 hours after the operation to observe the intraoperative pressure, and postoperative re-examination (half hour).
Note: Because ICL crystals require customized measurements, the operation time needs to be arranged according to the arrival time of the crystals, and the time will take relatively long.
5. The cost of surgery is different
Full femtosecond surgery : Generally more than 20,000 yuan/two-eye.
ICL crystal implantation : Generally more than 30,000 per eyes.
Warm reminder:
In short, full femtosecond and ICL crystal implantation have their own advantages. The surgical method needs to be selected based on the patient's specific myopia status, corneal thickness, etc.
It is recommended that the surgeon give a specific plan after undergoing an ophthalmology professional examination in the hospital. It is not that the more expensive the price, the better, and the best thing that suits you is.
