Full femtosecond laser surgery is mainly used to achieve the purpose of correction by making a lens between the corneas with a laser and then removing the lens. The incision that acts on the cornea is only 2-4mm, and it usually takes only a few minutes to ten minutes to complete the operation. Full femtosecond surgery is characterized by less trauma and faster recovery. It is generally suitable for people with myopia less than 1,000 diopters, astigmatism less than 500 diopters, no other eye diseases, and with sports needs. The price is usually between 1.8w-2.3w, and the cost is usually higher among the three.
Semi-femtosecond surgery mainly involves laser production of corneal flaps to change the shape of the cornea for refractive correction. During the surgery, the incision is usually larger due to the production of corneal flap, and it is not advisable to exercise strenuously after the surgery, which may easily lead to dislocation of the corneal flap, corneal inflammation, etc. Therefore, it is necessary to pay attention to the state of the eyes and eye hygiene after the surgery. 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 slightly lower than that of full femtosecond surgery.
Excimer laser surgery is to make a corneal flap on the cornea through the action of mechanical knife, in the use of excimer laser cutting corneal tissue, in order to achieve the purpose of vision correction. Post-operative stability is weaker than the previous two, if the postoperative care is not appropriate, it is easy to cause eye inflammation and other conditions, so you need to pay more attention to eye conditions during the recovery period, be vigilant about the emergence of abnormal conditions. The price is generally between 1.1w-1.5w yuan, and the price is also low among the three.
What kinds of laser myopia correction are there? Which is the best? Overall, the different types of laser correction surgery certainly have their own characteristics, the specific also need to make a suitable choice according to the individual's physical condition, economic status and so on. What's more, you should choose a regular hospital to perform the surgery, such as the vision of a hundred years of ophthalmology, its medical team are practicing for more than 20 years, "battle-hardened" refractive field experts, and equipped with cutting-edge medical equipment technology, so the vision of a hundred years of ophthalmology technology level in the industry is also at the forefront of the comprehensive speaking is more reliable.
