Semi-femtosecond laser treatment for myopia, the price usually ranges from 7000-10000 dollars. If it is purely semi-femtosecond, the price is around$7,000. If semi-femtosecond is added with individualized cutting, such as corneal topography-guided excimer laser or Q-guidance-guided excimer laser, plus the cost of iris localization and so on, it is about$10,000. Semi-femtoseconds are divided into two steps: first, a corneal flap is made with a femtosecond laser in about 10 seconds. Second, after the flap is made, the excimer laser is used to cut the cornea, and the cutting time is also about 10 seconds for one eye. So the semi-femtosecond laser is generally divided into two steps, the two steps add up to the time of about 1 minute, the price is basically in the 6000-10000 dollars.
