The options for corrective eye surgery are many in this day and age, and of course this is done with preliminary tests and evaluations for eligibility and suitability by professionally trained eye specialists. The vast majority of LASIK patients enjoy good uncorrected vision postoperatively with minimal -if any- complications. Nighttime glare and dryness remain a problem for some patients, at least in the near term. But newer lasers with eye trackers and larger treatment zones allow surgeons to minimize the risk of these glare complications. Eye trackers reposition the laser if your eye moves; doctors sometimes treat a larger area of the cornea in patients whose pupils are larger than average, to ensure good vision after surgery. It's important to understand that before you have LASIK, it is critical to make sure your corneas are totally and completely stable. This is especially important for people who have been using contacts for years before they decide to opt for surgery. Many years of hard lens wear can cause significant alterations in the way your corneas work. They may take up to a year to recuperate and this is the reason that most contact wearers are asked to stop using contacts for a specified period of time before the surgery.
Doctors can't know in advance how long this re-shaping process will take, as every person has individual characteristics and its persons corneas return to their original shapes at their own pace. Usually this is determined by regular check-ups and if two prescription and cornea checks are identical, that's when you are determined ready for permanent surgery. Rushing this preparation process is inherently dangerous to your eyesight and no self-respecting doctor would proceed with the surgery before your eyes check out to be stable. If you wear soft contact lenses all day, but take them out at night, the minimum waiting period after ceasing contact use is at least a week. Other, more conservative surgeons may stretch it out to two or three weeks. If you want the benefits of corrective eye surgery, but don't want to go through he surgery itself, wearing 30-day contact lenses offers benefits similar to those of laser vision correction. Continuous wear contacts may be the right option for people who are considering LASIK but can't afford it, are unwilling to risk a surgical procedure, or aren't very good LASIK candidates because of their vision needs. Both 30-day contacts and LASIK can produce excellent quality of vision for the right candidates. But in addition to your immediate visual outcome, each has implications for your vision later in life that many people don't consider.
