Astigmatism is a common vision condition that results from an irregular curvature of the cornea or lens of the eye. This irregularity can cause blurred vision, headaches, and eye strain. Fortunately, there are several effective methods to correct astigmatism, ensuring patients can enjoy clearer vision. Below, Dr. Stein discusses available treatment options.
Understanding Astigmatism
In a healthy eye, the cornea and lens typically have a smooth curvature that helps to focus light directly onto the retina. In astigmatism, these surfaces are unevenly curved, resembling more the shape of a football than a basketball. This causes light to focus on multiple points within the eye or in front of or behind the retina, leading to visual distortion.
Corrective Lenses
For many individuals, the primary treatment for astigmatism is the use of corrective lenses. These include:
- Eyeglasses: Specifically designed glasses with cylindrical lenses help to compensate for the uneven curvature of the cornea.
- Contact Lenses: While standard contacts might not correct astigmatism, toric contact lenses are shaped in a way that helps to counteract the irregularity. For more severe cases, rigid gas-permeable (RGP) lenses may be recommended because they maintain their shape on the eye, providing clearer vision.
Surgical Options
Surgical treatments are also available and can provide a permanent solution to astigmatism. These include:
- LASIK Surgery: Perhaps the most well-known, LASIK involves creating a thin flap in the cornea, allowing a laser to reshape the corneal surface beneath. This procedure is highly effective for correcting both mild and moderate astigmatism.
- PRK (Photorefractive Keratectomy): Similar to LASIK, PRK removes the outer layer of the cornea completely to reshape it with a laser. It’s particularly suitable for people with thin corneas.
- LASEK (Laser-Assisted Sub-Epithelial Keratectomy): LASEK combines elements of LASIK and PRK. It involves loosening the outer corneal layer without removing it, thus allowing for laser reshaping.
- Refractive Lens Exchange: In cases where laser surgery isn’t appropriate, the eye’s natural lens can be replaced with an artificial one to correct vision.
Considerations and Consultation
Deciding on the best method to correct astigmatism involves considering various factors, including the severity of the astigmatism, the thickness of the cornea, and the overall health of the eyes. It is crucial to consult with a qualified ophthalmologist like Dr. Stein, who can provide a thorough examination and discuss the best treatment options tailored to individual needs.
