In fact, for patients with microphthalmia syndrome whose inner canthus distance is obviously widened and whose inner canthus is overgrown, the price is about 4,000 to 5,000 yuan. Mohs method is the best method at present, which can correct epicanthus and the width of epicanthus distance, and there is no vertical scar passing through the epicanthus after operation, and no new epicanthus will be produced. Its disadvantage is that the scar is obvious after operation, and it takes a year to gradually recover.
