Can laser eye surgery fix astigmatism?
What is Astigmatism?
Astigmatism is a refractive error that affects how the eye focuses light, leading to blurred or distorted vision at various distances. Unlike nearsightedness (myopia) or farsightedness (hyperopia), which result from irregularities in the shape of the eyeball, astigmatism is primarily caused by irregularities in the curvature of the cornea or the lens inside the eye.
What are the symptoms of Astigmatism?
- Blurred or distorted vision at all distances.
- Eyestrain and fatigue, particularly after extended periods of visual tasks.
- Difficulty driving at night due to glare and halos around lights.
- Headaches, especially after prolonged visual activities.
Diagnosing astigmatism typically involves a comprehensive eye examination conducted by an optometrist or ophthalmologist. This examination may include tests such as visual acuity assessment, refraction test, keratometry, and corneal topography to precisely measure the curvature of the cornea.
Treatment options for astigmatism vary depending on the severity and individual preferences. Traditional methods include prescription eyeglasses or contact lenses, which correct refractive errors by altering the way light enters the eye. However, for those seeking a more permanent solution, laser eye surgery offers a transformative approach.
Can laser eye surgery fix astigmatism?
Laser eye surgery, also known as refractive surgery, encompasses various procedures aimed at reshaping the cornea to correct refractive errors such as astigmatism, myopia, and hyperopia. Among the most widely performed techniques for astigmatism correction are LASIK (Laser-Assisted In Situ Keratomileusis) and LASEK (Laser Epithelial Keratomileusis)
LASIK (Laser-Assisted In Situ Keratomileusis):
LASIK is a popular and highly effective procedure for correcting astigmatism. During LASIK surgery, a thin flap is created on the surface of the cornea using either a microkeratome blade or a femtosecond laser. The flap is then lifted, and an excimer laser is used to reshape the underlying corneal tissue to correct the astigmatism. Finally, the flap is repositioned, where it adheres naturally without the need for sutures.
LASEK (Laser Epithelial Keratomileusis):
LASEK is another laser eye surgery option for astigmatism correction, particularly suitable for individuals with thin corneas or those ineligible for LASIK. Unlike LASIK, which involves creating a corneal flap, LASEK removes the outer layer of the cornea (epithelium) entirely before reshaping the underlying corneal tissue with an excimer laser. The epithelium naturally regenerates over several days following the procedure.
Advantages of Laser Eye Surgery for Astigmatism:
- Precise Correction: Laser eye surgery offers precise customization, allowing surgeons to precisely reshape the cornea to correct astigmatism and achieve optimal visual outcomes.
- Rapid Recovery: Many patients experience rapid visual recovery following laser eye surgery, with significant improvements in vision within the first few days after the procedure.
- Reduced Dependence on Corrective Eyewear: By addressing astigmatism at its source, laser eye surgery can significantly reduce or eliminate the need for prescription eyeglasses or contact lenses, providing greater freedom and convenience.
- Long-Term Results: Laser eye surgery provides long-term correction of astigmatism, offering lasting improvements in visual acuity and quality of life for eligible candidates.
Whether through LASIK or LASEK, laser eye surgery offers an opportunity to those seeking clarity and freedom from the limitations of astigmatism and the use of corrective glasses or contact lenses.
