All-femtosecond surgery is mainly to make a lens between corneas by laser and then take it out to achieve the purpose of correction. The incision acting on the cornea is only 2-4mm, and it usually takes only a few minutes to ten minutes to complete the operation. All-femtosecond surgery has the characteristics of less trauma and quick recovery. Generally suitable for people with myopia/kloc-below 0/000 degrees and astigmatism below 500 degrees, who have no other eye diseases and need exercise. The price is generally between 1.8w-2.3w, and the cost is usually higher among the three.
Semi-femtosecond surgery is mainly to make corneal flap by laser to change corneal morphology and achieve refractive correction. Because the corneal flap is made during the operation, the incision is usually large, so it is not suitable for strenuous exercise after the operation, which may easily lead to dislocation of the corneal flap and corneal inflammation. After the operation, more attention should be paid to the eye condition and eye hygiene. Semi-femtosecond is suitable for people with myopia not higher than 1200 degrees, astigmatism less than 600 degrees and no other eye diseases. The price is generally between 1.7w-2.0w, which is generally slightly lower than that of full femtosecond surgery.
Excimer laser surgery is to make corneal flap by mechanical knife acting on cornea, and then cut corneal tissue with excimer laser to achieve the purpose of correcting vision. Postoperative stability is weaker than the first two, and improper postoperative maintenance can easily lead to eye inflammation. It is necessary to pay more attention to eye conditions and be alert to abnormal conditions during the recovery period. Compared with the first two, it is applicable to a wider range of people, and the price is generally between 1. 1w- 1.5w, which is also the lower of the three.
What kinds of myopia are corrected by laser? Which is the best? Generally speaking, different types of laser correction surgery certainly have their own characteristics, and it is necessary to make appropriate choices according to the personal physical condition and economic situation. More importantly, we must choose a regular hospital for surgery, such as Vision Centennial Ophthalmology. Their medical team is an expert in the field of refraction who has been working for more than 20 years and is equipped with cutting-edge medical equipment and technology. Therefore, the technical level of visual ophthalmology in the past 100 years is also at the forefront in the industry, and it is relatively reliable as a whole.
