The principle of corrective surgery for myopia is the same as that of wearing glasses. It is divided into two correction methods: click to consult manual customer service to learn more
First, perform myopia surgery on the cornea For corrective surgery, the normal myopia lens is a concave lens, which can cut a part of the cornea to make the cornea concave, that is, make the cornea look like a myopia lens.
Second, corrective surgery involves intraocular lens implantation for phakic eyes. Since you don’t want to wear a mirror and want to correct myopia, you can put the myopia lens directly into the eye, that is, calculate the degree of the myopia lens. Then the corresponding intraocular lens is implanted into the eye to correct myopia. This is very similar to cataract surgery, but for cataract surgery, the original lens is taken out and the intraocular lens is inserted. In myopia correction surgery, the original lens is not moved and another lens is placed in front of the lens.
Currently commonly used corrective surgeries for myopia include excimer laser, femtosecond laser, and semi-femtosecond laser. If you are not suitable for these surgeries, a very high degree of myopia, for example, a myopia degree greater than 1,000 degrees. When the astigmatism reaches 1,200 degrees, or exceeds 1,200 degrees, and the astigmatism is within 600 degrees, another option is to undergo ICL intraocular lens implantation. It is to place the intraocular lens in the phakic eye. It is placed in front of the normal lens. It is called posterior chamber phakic intraocular lens implantation. The problem it solves is mainly ultra-high myopia.
