Astigmatism correction is a treatment designed to address visual distortion resulting from an irregularly shaped cornea or lens. This condition occurs when the cornea or lens is uneven, causing light to focus incorrectly on the retina, which leads to blurred or distorted vision. Correction methods include toric lenses, specifically designed to counteract the corneal irregularities, and surgical procedures like laser treatments that reshape the cornea. The primary goal is to correct the alignment of light on the retina, thereby providing clearer and more focused vision. Various techniques are available to address astigmatism based on individual needs and severity.
