Not bad. General myopia surgery clinical recruitment is free. Now many hospitals in China can carry out PRL crystal implantation surgery. The correction range of the first generation product is between1000 and 3000 degrees, and PRL-S5 intraocular lens is the second generation product based on the mirror. Now it is being recruited in clinic, and the scope of correction is wider, which can correct myopia of 300~2800 degrees. You can find out for yourself if you need it. Because the two generations of products have the same correction principle and the same crystal material, the only difference lies in the product design, so the overall safety and effectiveness are still very worth looking forward to.
