What Is Astigmatism?
Astigmatism is a common refractive error that affects how the eye focuses light onto the retina. It occurs when the cornea or lens has an irregular shape, more like an oval or rugby ball than a perfect sphere. This uneven shape causes light to focus at different points, resulting in blurred or distorted vision.

Astigmatism Treatment Options
Corrective lenses, such as glasses or contact lenses, are commonly prescribed to correct astigmatism and improve vision. For those who are unable to tolerate or prefer not to rely on glasses or contact lenses, LASIK or ICL (Implantable Collamer Lens) may be considered.
Cataract Surgery for Astigmatism Correction
Modern advancements in cataract surgery offer effective options for addressing astigmatism. During cataract surgery, the cataractous lens is replaced with an advanced technology lens implant, which can also correct astigmatism and provide clearer vision, potentially reducing the need for glasses or contact lenses.
