LASIK Complications and Risks (2)

Here's the beginning of LASIK Complications and Risks List :

1. Undercorrection and Overcorrection
Undercorrection is a result of not enough corneal tissue is removed during the surgery, while contrary to undercorrection, too much tissue removed during the LASIK procedure may caused an overcorrection result. Undercorrection is more common than overcorrection in any refractive surgery. Both problems are often temporary and decreases as the cornea stabilizes, but sometimes can be permanent. However, enchancement surgery may likely resolve permanent undercorrection or overcorrection, while temporary conditions of undercorrection and overcorrection can be treated with glasses or temporary contact lenses until they resolve.

2. Irregular Astigmatism
Irregular astigmatism may happen if the laser correction is not centered properly on the eye or if the microceratome results a less smooth corneal surface. This condition can be treated with second LASIK procedure (enhancement surgery).

3. Dry Eye
It is normal if you feel dry, itchy or scratchy on eye after LASIK surgery. This temporary problem lasts for about 4 weeks and decreases as your cornea has healed properly. That is why your doctor will give you lubricating eye drops or maybe artificial tears to treat dry eye.

4. Corneal Abrasion
Corneal abrasion is a small breakdown in the epithelial surface caused when microkeratome makes the corneal flap. This happens in a small percentage of LASIK procedures because in some eyes, the surface cells may not adhere well. But don’t worry, as the epithelium grows back quickly within one to three days. To improves comfort and promotes healing, doctor will give you a very thin bandage contact lenses if this problem occurs.

5. Night Glare, Halos, Sensitivity to Light and Hazy or blurred vision
Most of LASIK patients experience these temporary complications for one week up to one month after LASIK eye surgery. However, some patients may experience these kinds of refractive errors due to the presence of higher order aberrations, which can be treated with Custom LASIK or Wavefront-guided LASIK. Oversize pupil also could cause the night vision problems due to LASIK treatment zone is smaller than pupil’s larger size.
