LASIK

LASIK, short form for Laser-Assisted in situ Keratomileusis is a type of refractive laser eye surgery performed by ophthalmologists for correcting myopia, hyperopia, and astigmatism.

The procedure is generally preferred to photorefractive keratectomy, PRK, (also called ASA, Advanced Surface Ablation) because it requires less time for the patient's recovery, and the patient feels less pain, overall; however, there are instances where PRK/ASA is medically indicated as a better alternative to LASIK. Many patients choose LASIK as an alternative to wearing corrective eyeglasses or contact lenses.

Like any others treatment, there must be a few possible complications.
Preliminary results of USAEyes Competence Opinion Relative to Expectation (CORE) patient survey provided to FDA panel on April 25th indicate Lasik is safe, predictable, not always perfect.

The possible Lasik complications are :
• surgery induced dry eyes
• visual acuity fluctuation
• Halos or starbursts around light sources at night
• Light sensitivity
• Ghost images or double visions
• Wrinkles in flap
• Decentered ablation
• Debris or growth under flap
• Thin or buttonhole flap
• Induced astigmatism
• Corneal ectasia
• Floaters
• Epithelium erosion
• Posterior vitreous detachment
• Macular hole
