1.What are keratoplasty lenses? Corneal shaping lens is a kind of hard contact lens with the principle of physical way, after special geometric design, worn on the corneal surface when sleeping, and flattened by tears in the central part of the cornea, to achieve the improvement of vision and control the growth of myopia in a natural way. 2.What are the effects and benefits of wearing keratoconus lenses? There are two major benefits of wearing keratoplasty lenses: (1) No need to wear any glasses during the day, clear vision in the naked eye, to achieve the effect of no myopia. (2) It can effectively curb the rapid progression of myopia, slow down the growth of the eye axis, and reduce the chance of high myopia fundus lesions. 3.Who can wear keratomileusis? (1) Age 8~35 years old (over 35 years old can also try, but there may be discomfort in close reading).

(4) Intraocular pressure between 11~21mmhg. (5) Eye health and good hygiene habits. 4.Does wearing keratoconus have side effects? Theoretically, there are still complications associated with contact lenses, such as corneal infection, epithelial punctal detachment, and conjunctival congestion. However, because these lenses are made of special high oxygen permeable materials and are worn at night, the possibility of complications can be minimized if scientific wearing methods are strictly followed. Most of the problems can be recovered by suspending wearing. 5.How long can a pair of keratoplasty lenses be worn?
