Astigmatism of 150 degrees can affect vision to varying degrees, so this condition needs to be corrected early. Depending on the age, the method of correction is different. In the case of minors, astigmatism can be corrected by two methods: frame glasses or corneal contact lenses. For adults, in addition to the two methods mentioned above, you can also consider keratoconus surgery to correct astigmatism, including the excimer laser or femtosecond laser, which are commonly used for the correction of astigmatism. Astigmatism is usually caused by irregularities in the shape of the cornea, so this condition does not usually change with age and does not get either larger or smaller.
