Free LASIK Complication Management Questions and Answers

Question 1

What is the most common complication following LASIK surgery?

Accepted Answer

Dry eye syndrome

Answer

Dry eye syndrome is the most common complication following LASIK surgery. The creation of the corneal flap can temporarily disrupt corneal nerves responsible for tear production and sensation, leading to reduced tear film stability and increased dryness. While usually temporary, it can cause discomfort and blurry vision, requiring management with artificial tears.

Question 2

What complication can occur if the corneal flap is not properly repositioned?

Accepted Answer

Flap striae

Answer

Flap striae are microscopic folds or wrinkles in the corneal flap that occur if it is not perfectly smoothed and aligned after repositioning. These striae can cause visual distortion, glare, and reduced visual acuity. Proper intraoperative technique and careful repositioning are crucial to prevent them, ensuring a smooth optical surface.

Question 3

Which sign indicates the presence of diffuse lamellar keratitis (DLK)?

Accepted Answer

Sterile interface inflammation

Answer

Diffuse lamellar keratitis (DLK), also known as 'sands of the Sahara,' is a sterile inflammatory reaction that occurs in the interface between the corneal flap and the stromal bed. It is characterized by a diffuse haze or granular appearance in the interface, caused by an accumulation of inflammatory cells. It is not an infection but an inflammatory response.

Question 4

How is epithelial ingrowth best managed postoperatively?

Accepted Answer

Lift flap and irrigate interface

Answer

Epithelial ingrowth occurs when epithelial cells from the corneal surface grow under the repositioned flap. If significant or visually compromising, the most effective management is to lift the flap and mechanically remove the epithelial cells from the interface. This is followed by thorough irrigation to prevent further growth and potential flap melting or irregular astigmatism.

Question 5

What is the initial treatment for DLK?

Accepted Answer

Corticosteroids

Answer

Diffuse lamellar keratitis (DLK) is a sterile inflammatory condition, not an infection. Therefore, the initial and primary treatment involves topical corticosteroids to suppress the inflammatory response. Early and aggressive treatment with steroids can often resolve DLK and prevent progression to more severe stages that could impact vision.
