Some risks of Lasik include:

• Incomplete Corrections
• Decentered Ablations
• Oversized pupils
• Haze
• Irregular flaps
• Dry eye
• Diffuse Lamellar Keratitis
• Epithelial Growth
• Infection

See below, these are addressed in the following table:

Complications	Symptoms	Treatments
Incomplete corrections (undercorrection, overcorrection, residual astigmatism)	Blurry, less-than-perfect vision	Glasses or contact lenses; eyedrops; re-treatment with laser
Decentered ablations	Visual aberrations	Eyedrops; re-treatment with laser
Oversize pupils (pupils wider than treatment zone)	Visual aberrations	Eyedrops; re-treatment with laser
Haze	Visual aberrations	Eyedrops; re-treatment with laser
Irregular flap (folds, wrinkles, striae)	Visual aberrations	Surgical correction; second laser procedure
Dry eye	Dry, itchy or scratchy eyes, often with redness and sense of foreign object in eye, and sometimes pain	Prescription dry eye medication; artificial tears; punctal occlusion (blockage of tear ducts in order to retain tear film on eye), oral flaxseed oil
Diffuse lamellar keratitis (eye inflammation)	Visual aberrations	Eyedrops; surgical rinsing of cells
Epithelial ingrowth	Visual aberrations	Surgical removal of epithelium
Infection	Redness, oozing of eyes, sometimes pain	Eyedrops; oral medications
