First of all, the principle is different
1, full femtosecond: do "subtraction" on the cornea: adjust the diopter of the eyeball by cutting the cornea with femtosecond laser, so as to achieve the purpose of correcting vision. Because the curved small incision looks like a smiling face, it is commonly known as a full femtosecond smile.
2.ICL: Intraocular "addition": under the condition of not cutting the corneal thickness, the vision is corrected by implanting ICL intraocular lens in the eye, with a wide correction range (myopia 1800 and astigmatism within 600 degrees), which can be taken out or replaced at any time.
Second, the location is different.
1, full femtosecond: corneal ablation site: corneal stroma layer
2.ICL:ICL implantation position: located behind the iris (the colored part of the eye)
Third, the process is different.
1, Full Femtosecond Surgery: 1) Eye drops for topical anesthesia. 2) Fabrication of microlens by femtosecond laser scanning. 3) Femtosecond laser is used to make micro-incision. 4) separating and taking out the corneal stroma lens. 5) The operation is completed.
2, ICL operation process: 1) Eye drops for topical anesthesia. 2) Make a small incision between the black and white eyes. 3) Inject the gel into the eye to protect the tissue in the eye, and then inject the ICL into the eye. 4) Adjust the ICL to a proper position and suck the gel out of the eyes. 5) The operation is completed.
Fourth, it is suitable for different people.
1, full femtosecond: it is suitable for athletes and other patients who have high requirements for corneal stability and safety after operation.
2.ICL: People with high myopia and thin cornea who are not suitable for laser myopia correction can consider it.
Fifth, the preparation time is different
1, full femtosecond: 2-3 days are reserved from preoperative examination to operation (available on weekends). Preoperative examination (2 hours), rest for surgery on the second day (all day), and reexamination on the third day (half an hour). Actual operation time: 10 minute.
2, ICL: from preoperative examination to surgery, reserved for about one month. Preoperative examination (2 hours the day before), crystal reservation (1-2 weeks), operation time+hospitalization observation 1 day after crystal arrival, and postoperative review (half an hour). Actual operation time: 10 minute.
Sixth, the price is different.
Icl crystal implantation >: full femtosecond
The difference in cost mainly lies in the crystal, because ICL artificial crystals are tailor-made, and its higher cost directly determines its relatively higher price.
