return to surgeries

Astigmatic keratotomy eye surgery is safe and effective, but in recent years has been largely replaced by LASIK. The cornea of people who have astigmatism is shaped like a football. Astigmatic keratotomy eye surgery corrects astigmatism by making one or two incisions at the steepest part of the cornea. These incisions cause the cornea to relax and take a more rounded shape.

People with mild prescriptions generally have the best success in obtaining normal vision after astigmatic keratotomy eye surgery. People with more severe astigmatisms may still require glasses or contact lenses after astigmatic keratotomy eye surgery.

Today, most patients have AK done in conjunction with another surgery, for example NLR or cataract surgery to reduce or eliminate residual astigmatism. It is rarely a primary procedure anymore.

What Are the Advantages of Astigmatic Keratotomy Eye Surgery?

Astigmatic keratotomy eye surgery is a safe and effective way to correct astigmatism.

What Are the Disadvantages of Astigmatic Keratotomy Eye Surgery?

• Slow healing process (about three months)
• Discomfort (usually lasting 2-3 days)
• Results, both good and bad, are irreversible

What Are the Potential Side Effects of Astigmatic Keratotomy Eye Surgery?

Although rare, side effects from astigmatic keratotomy eye surgery can occur. They may include:

• Fluctuating vision, especially during the first few months after surgery
• A weakened cornea, more vulnerable to rupture if hit directly
• Infection
• Difficulty in fitting contact lenses
• Glare or starburst around lights that can sometimes be permanent
