What to Expect

Some people may or may not experience the following:

The First Week Following PRK/LASEK

• Pain and discomfort may last for up to 3 days after surgery
• Blurred vision and tearing may occur as the cornea heals
• You will be sensitive to bright lights for the first few days
• The First Two To Six Months Following PRK/LASEK
• Your intraocular pressure may increase due to use of anti-inflammatory medications. This is usually resolved by drug therapy or by stopping the anti-inflammatory medication.
• Your cornea may become hazy or cloudy enough to affect your vision. This haze typically disappears over time, but some patients continue to experience haze over 2 - 3 years.

The First Week Following TF-LASIK

• There should be no pain
• You should experience an immediate return of vision (the next day)
• Epithelial ingrowth could occur (rare: cells growing under the flap)
• Stromal Inflammation
• Flap decentration (rare)
• Flap damages by the microkeratome (rare)

More Than One Year After Surgery

Clinical studies for Conventional LASIK and PRK showed that at one or more years after surgery, the following percentages of patients still had problems with their vision:

Difficulty with night vision*	3.9%
Increased sensitivity to light	3.0%
At least one diopter worsening of nearsightedness	2.8%
Double vision worse after surgery if present before surgery	1.3%

* With the new lasers and laser software, we expect this percentage to decrease.
* With the new lasers, TF-LASIK and WaveFront technology, these percentages can be greatly reduced.The studies also showed that the following vision-threatening events happened less than 1% of the time after Conventional LASIK surgery:

• Losing a significant amount of vision even with glasses.
• Too large a correction (causing farsightedness).
• Lens abnormality (for example: cataract, opacity or cloudiness).
• Visually significant corneal haze.
