ALK (Keratoplasty Eye Surgery )

Automated Lamellar Keratoplasty (ALK) is a surgical procedure to correct the vision in people with severe nearsightedness and mild farsightedness.

How is  Keratoplasty Eye Surgery performed?

Keratoplasty eye surgery is performed under local anaesthetic. And, usually takes less than one hour to complete. A cutting device is used to make a small incomplete flap across the cornea. While it is still attached at one side, the corneal flap is folded back to reveal the layer of tissue below. Another very accurate cut is made on the sub-layer of tissue based on the patient’s glass prescription. After the cut, the corneal flap is placed back over the eye to reattach. 

What are the Advantages of Keratoplasty Eye Surgery?

• healing process is relatively quick and comfortable.

• takes lesser time for stable vision to regain.

What are the Disadvantages of Keratoplasty Eye Surgery?

• people with mild to moderate nearsightedness, the keratoplasty eye surgery is not as accurate as other eye procedures. The outcome is more difficult to be predicted.

• it slightly increases the risk of developing an irregular astigmatism.

What are the Potential Side Effects of Keratoplasty Eye Surgery?

How to prepare for keratoplasty eye surgery?

• Eye test, evaluation of  medical history. Likely tests may include measuring corneal thickness, refraction, and pupil dilation. 

• Usually it is advised not to wear rigid gas permeable contact lenses for 03 weeks before surgery while other types of contact lenses shouldn't be worn for at least 03 days prior surgery. 

• Carry your glasses to the surgery so that your prescription can be reviewed.
