Astigmatism is a common refractive error that occurs when the cornea or lens of the eye has an irregular shape, causing blurred or distorted vision at any distance. Fortunately, several treatment options are available to correct astigmatism and improve visual acuity.

1. Eyeglasses: Prescription eyeglasses are a common and effective treatment for astigmatism. Specially designed lenses, known as toric lenses, compensate for the irregular shape of the cornea or lens, allowing light to focus properly on the retina.

2. Contact Lenses: Toric contact lenses are another popular option for correcting astigmatism. These lenses have different powers in different meridians, aligning with the irregular curvature of the eye to provide clear vision. Soft toric lenses are available for mild to moderate astigmatism, while rigid gas permeable (RGP) lenses may be recommended for more severe cases.

3. Refractive Surgery: LASIK (Laser-Assisted in Situ Keratomileusis) and PRK (Photorefractive Keratectomy) are surgical procedures that can reshape the cornea to correct astigmatism, along with nearsightedness or farsightedness. During LASIK, a laser is used to create a flap in the cornea, which is then reshaped to correct the refractive error. PRK involves removing the outer layer of the cornea before reshaping it with a laser. These procedures offer long-term vision correction but require careful evaluation and candidacy assessment by an eye care professional.

4. Implantable Lenses: For individuals with high levels of astigmatism or those ineligible for LASIK or PRK, implantable collamer lenses (ICLs) or toric intraocular lenses (IOLs) may be considered. These lenses are surgically implanted inside the eye to correct refractive errors and provide clear vision.

Overall, the choice of treatment for astigmatism depends on factors such as the severity of the condition, lifestyle preferences, and the individual’s overall eye health. Consulting with Dr. Rachna Kapoor, an eye care specialist, can help determine the most suitable treatment option for each individual.
