Astigmatic Keratotomy (AK) is a surgical procedure at Global Eye Hospital Kukatpally, Global Eye Hospital Narsingi used to correct astigmatism, a common refractive error that results from an irregularly shaped cornea or lens. AK is a type of corneal incisional surgery that involves making precise incisions in the cornea to reshape it and improve vision.
How does Astigmatic Keratotomy work?
AK is performed using a special diamond blade to create small incisions in the cornea. The incisions are made in a specific pattern based on the patient’s individual astigmatism. The incisions cause the cornea to relax and change its shape, reducing the amount of astigmatism present.
What are the advantages of Astigmatic Keratotomy?
One of the main advantages of AK is that it is a minimally invasive procedure that does not involve the use of lasers. This means that the procedure can be performed quickly and is generally less expensive than other types of refractive surgeries.
Another advantage of AK is that it can be used to correct both low and high levels of astigmatism. Additionally, AK is reversible, meaning that the incisions can be adjusted or reversed if needed.
Who is a good candidate for Astigmatic Keratotomy?
AK is generally recommended for patients with low to moderate levels of astigmatism who are not good candidates for other types of refractive surgeries, such as LASIK or PRK. AK may also be recommended for patients who have previously undergone refractive surgery and have developed astigmatism as a result.
Patients with thin corneas or dry eyes may be good candidates for AK as well.
What are the risks and side effects of Astigmatic Keratotomy?
As with any surgical procedure, AK does carry some risks and potential side effects. Some patients may experience dry eyes, glare, halos, or blurred vision after the procedure. These side effects are typically temporary and subside over time.
There is also a small risk of infection or other complications, although this is rare.
Conclusion
Astigmatic Keratotomy is a minimally invasive surgical procedure that can be a good option for patients with low to moderate levels of astigmatism who are not good candidates for other types of refractive surgeries. If you are interested in AK, it is important to consult with a qualified eye surgeon to determine if you are a good candidate and to discuss the risks and benefits of the procedure.
