Astigmatism is a common refractive error in which the cornea or the eye's lens has an uneven curvature. This causes light to focus unevenly, resulting in blurred or distorted vision at near or far distances. Astigmatism may occur on its own or alongside myopia (short-sightedness) or hyperopia (long-sightedness). Mild astigmatism may not cause noticeable symptoms, while more significant astigmatism can interfere with reading, driving, and other daily activities.
Timely treatment matters because it provides clear, comfortable vision and can reduce eye strain, headaches, and difficulty seeing at night. In children, early detection matters because significant, untreated astigmatism can interfere with normal visual development and may contribute to amblyopia (lazy eye). Regular eye exams can identify astigmatism early and determine the best vision correction.
Causes
Risk Factors
Refractive surgery: Refractive surgery can treat astigmatism, depending on its type and severity. Some of the surgical techniques are
LASIK (Laser-assisted in-situ keratomileusis) : In this procedure, an eye surgeon makes a thin, hinged flap in the cornea, uses an excimer laser to sculpt the cornea's shape, and then repositions the flap.
Cost Start From 2500Explore Options
LASEK (laser-assisted subepithelial keratectomy): The surgeon loosens the corneal surface (epithelium), which is a thin cover on the cornea. Utilizes an excimer laser to alter the curvature of the cornea and then repositions the loosened epithelium over the cornea.
PRK (Photorefractive keratectomy): This procedure is similar to LASEK, except the surgeon removes the epithelium. The epithelium regenerates to form the new corneal shape. You may need a bandaged contact lens for a few days after surgery.
SMILE (small incision lenticule extraction): This newer type of refractive surgery reshapes the cornea by using a laser to make a lens-shaped bit of tissue (lenticule) below the cornea's surface. The surgeon then extracts the lenticule through a very small incision.
