Interview with “The Ophthalmologist”
Irregular astigmatism knows various underlying causes, including previous complicated eye surgery, and diseases like keratoconus. A common feature of irregular astigmatism is the fact that it cannot be readily corrected with glasses or conventional contact lenses.
Here, therapeutic refractive laser surgery may help. The aim here is not to free a patient from glasses or contact lenses, but rather to regularize the cornea, improving vision that can otherwise not be improved with glasses/contact lenses.
