Are you considering LASIK to correct your astigmatism? Wondering if it’s really the best procedure for this type of refractive error?
The short and honest answer is yes! LASIK remains one of the safest and most effective treatments for astigmatism and other common vision problems, so you’re in good hands!
If you’re curious about LASIK for astigmatism, you’re in the right place. Read on to learn how the procedure works, how it corrects refractive errors, and key facts you should know.
What is astigmatism?
To gain an understanding of how LASIK for astigmatism works, it helps to understand the type of refractive error you have.
Astigmatism occurs when the cornea has an irregular shape, causing light to focus on two points on the retina instead of just one. Normally, the cornea is round like a basketball, but with astigmatism, it’s shaped more like a rugby ball, more elongated.
Since the light cannot properly focus on the retina, this results in blurred or distorted vision at all distances
Astigmatism is not considered a severe refractive error. In fact, most people have it to some degree, but many don’t require treatment.
When correction is necessary (as recommended by your doctor), it can be managed with glasses or contact lenses. However, LASIK offers a longer-term, more cost-efficient solution since you won’t need to worry about the cost of replacement or repairs.
How does LASIK for astigmatism work?
LASIK may seem complicated and intimidating at first, with all the equipment involved, but it’s actually a pretty straightforward procedure.
LASIK for astigmatism is considered a safe and virtually painless treatment. It works by carefully reshaping the cornea, correcting its uneven curvature to a more rounded form, which improves the way light enters the eye for clearer vision.
During the procedure, a thin flap is created on the surface of the cornea using a femtosecond laser, which is then gently folded back to expose the underlying corneal tissue.
Then, a specialised excimer laser is used to precisely and carefully reshape the corneal tissue, correcting the refractive error. A tiny amount of tissue is removed to achieve the ideal curvature with each movement of the laser beam.
Once the reshaping is complete, the corneal flap is folded back into its original place, where it naturally heals with the need for stitches.
The entire LASIK for astigmatism only takes about 20 to 30 minutes for both eyes, with a quick and hassle-free recovery period. Most patients are able to return to their normal routines within 1–2 days, provided that proper precautions are taken during the recovery period.
Is LASIK for astigmatism effective?
Whether it’s for astigmatism or farsightedness, LASIK is an incredibly effective vision correction procedure, with nearly 90% of patients achieving close to 20/20 vision after full recovery.
It’s worth mentioning here that LASIK may not be suitable for all levels of astigmatism.
For example, mild cases can often be corrected in a single session, while more advanced or severe cases may require additional treatments. Some are even recommended to undergo a combination of procedures to achieve desirable results.
How do you know if you’re qualified for LASIK for astigmatism?
As with any medical procedure, you will have to undergo diagnostic tests to determine if you’re a good candidate for LASIK.
In general, candidates should be at least 18 years old, in good overall health, have a stable prescription for at least a year, and have no other significant eye conditions.
Additional tests are still needed to check whether your eyes have the proper corneal topography and structure for the procedure.
However, certain conditions like severe dry eyes, unstable glaucoma, and uncontrolled diabetes may render you unqualified for the procedure.
