Can I Have LASIK with Astigmatism?
This is a common question that many patients have when they are beginning to research whether or not they are a candidate for LASIK. Astigmatism is a commonly misunderstood term; it is a type of refractive error similar to farsightedness or nearsightedness. Astigmatism is actually the most common type of prescription found when determining the power someone needs in his or her glasses or contact lenses. It simply means a person’s vision correcting prescription has two components rather than one, so there is a segment of the prescription that is stronger than the rest.
LASIK with Astigmatism: Utilizing the Latest Technology
Thanks to advancements in technology over the past several years people with astigmatism are likely to still be great candidates for LASIK or PRK. This investment that Dr. Mozayeni as made in the most recent state of the art FDA approved technology, and his 20+ years of vision correction surgery experience, is what truly differentiates Providence Eye & Laser Specialists and allows us to treat astigmatism effectively. We commonly see patients that have been told they are not LASIK candidates at another practice come to who come to Providence Eye for a second opinion and turn out to be great LASIK or PRK candidates.
There are more factors in determining whether patients with astigmatism can have LASIK or PRK eye surgery than just their prescription. In most cases, patients with astigmatism have a cornea that it is steeper or flatter in one direction. At Providence Eye & Laser Specialists, we utilize a corneal mapping device called the Pentacam that provides a three-dimensional image of the cornea, showing its shape, thickness, and structural integrity. With this information, it can be determined if a patient with astigmatism can still safely have LASIK or PRK. Most patients have a corneal shape that is normal for their prescription, even with astigmatism, and LASIK can safely be performed.
There are some corneal diseases, such as keratoconus, that can cause a patient to have astigmatism due to overall cornea instability. Keratoconus causes a gradual weakening of the corneal tissue that causes patients to develop larger amounts of astigmatism over time. In this specific case, neither LASIK nor PRK should be performed because it would compromise the already fragile cornea structure. Dr. Mozayeni’s extensive experience and expertise as a fellowship-trained cornea specialist is critical to ensure you are a good candidate for LASIK eye surgery.
