Best answer: What is DLK after Lasik?

What is DLK?

Diffuse lamellar keratitis (DLK) is a sterile inflammation of the cornea which may occur after refractive surgery, such as LASIK. Its incidence has been estimated to be 1 in 500 patients, though this may be as high as 32% in some cases.

How is DLK treated after LASIK?

Given its inflammatory nature, all stages of DLK typically respond well to corticosteroid therapy. In certain cases irrigation beneath the flap followed by flap repositioning can remove subepithelial infiltrates and minimize complications associated with the condition.

What causes DLK after LASIK?

Diffuse lamellar keratitis (DLK) is a relatively infrequent complication of LASIK [1]. It may occur after any surgical procedure in which a corneal lamellar incision has created an interface through the stromal tissue.

How long does DLK last?

DLK is defined by infiltrative white cells at the interface of the LASIK flap. These infiltrative cells are diffuse in the central or peripheral flap interface and respond to increased topical steroids. DLK will typically resolve in 5 to 8 days and only rarely has any impact on the final refractive outcome.

What is toxic Keratopathy?

The Central Toxic Keratopathy (CTK) syndrome describes a rare, acute, self-limited, non-inflammatory process that yields central corneal opacification and significant hyperopic shift after refractive surgery.

How can DLK be prevented?

To reduce the incidence of DLK, LASIK surgeons should follow the standardized aseptic techniques, including using a single blade for every patient. Blades should not be used on multiple patients because of the risk of HIV and hepatitis, as well as prion-associated disease.

How long does inflammation last after LASIK?

1. How long is recovery after LASIK? Most people can see clearly immediately after surgery, and any soreness or redness should be gone in about a week. The cornea does most of its major healing during the first two to four weeks after surgery; however, full recovery takes from three to six months.

What happens if LASIK fails?

Aside from removing too much or too little corneal tissue, surgeons can remove eye tissue unevenly. This mistake can happen if they fail to center the laser properly on the eye. The result can be astigmatism or the general blurring of vision at any distance.

What is infectious keratitis?

Bacterial keratitis is an infection of the cornea (the clear dome covering the colored part of the eye) that is caused by bacteria. It can affect contact lens wearers, and also sometimes people who do not wear contact lenses.
