Laser Vision Correction

Additional Issues to Consider
Although not technically considered as risks of refractive surgery, the following potential problems should be considered by anyone contemplating refractive surgery.

Impaired Night Vision: Recent media reports suggested a link between LASIK and reduced night vision. However, these were based on an English study that used old lasers on patients requiring high levels of correction. The vast body of evidence from studies conducted at world-recognized refractive laser centers demonstrates an incidence rate of less than 2%. In most cases, these effects are not troublesome. It should be noted that night vision problems after LASIK are linked to factors such as large pupil size, unusually flat corneas or the use of a laser with a small treatment zone. Checking for factors which would pre-dispose someone to night vision problems is a routine part of a pre-operative exam at the Casey Vision Correction Center. Casey's excimer lasers can be programmed to treat larger optical zones thus minimizing the incidence of night vision problems.

Possibly needing corrective lenses. No refractive surgery can promise everyone perfect results and no reputable surgeon will make such a guarantee. Every eye has its own unique healing pattern and the occasional person may not heal as expected. In these cases, glasses may be needed for activities such as driving or watching television. In general, the more severe the focusing problem before surgery, the greater the likelihood that an enhancement may be appropriate or that glasses may be needed occasionally after surgery.

Needing reading glasses. No eye surgery can prevent presbyopia, so if you already need reading glasses or bifocals, you will still require reading glasses after surgery. If you are in your twenties or thirties, reading glasses will probably become necessary in the next few decades. For some people, monovision (different levels of correction for each eye) may be a viable alternative.
