The best age for astigmatism to correct vision is before the age of 6, as 0 to 6 years is the period of eye development for children. Methods include early dilated optometry and wearing pillar lenses, in addition to surgical treatment. 1. Wearing column lenses: Different column lenses can be used to correct astigmatism. Convex lenses are used for hyperopic astigmatism and concave lenses for myopic astigmatism. They are categorized according to the type of astigmatism and the degree of astigmatism. 2. Surgical treatments: such as laser keratoplasty, excimer laser refractive corneal surgery, keratotomy, etc. Intraocular refractive surgery is usually a type of artificial lens implantation with crystalline lens and is indicated for astigmatism that is congenital, caused by eye surgery such as cataract or after corneal transplantation. Determining the age of correction should also take into account the specifics of the situation, such as the presence of amblyopia, how cooperative the child is, and the degree of astigmatism. When astigmatism is detected, the child needs to be examined, corrected and treated in a timely manner, and the earlier the intervention, the better the outcome.
