The term “Lasik” applies to an assortment of eye surgery options, such as:

  • All laser Lasik;
  • Conventional;
  • PresbyLasik;
  • Monovision Lasik;
  • Customer Lasik or Lasek.

Applicants for any of these events undergo careful examination to make sure that this surgery option is suitable for their condition.

Excimer laser refractive surgery

This is normally known as laser correction, and has been accessible for the past twenty years.  This is a surgery procedure performed to reduce or eliminate the need for contact lenses or glasses.  If you are considering laser surgery, you need to know what it is, what to expect and what the benefits, risks and alternative are.

Designed for

Laser surgery is surgery developed to help those who are hyperopic or farsighted, or myopic or near-sighted, as well as astigmatism, which is an irregularity in the surface of the cornea in the front of the eye

Not for everyone

Laser surgery is regrettably not for everyone.   A good candidate for this surgery is:

  • Over the age of 18 years old;
  • Wants to reduce or eliminate the need for contact lenses or glasses;
  • Vision stable for at least one year;
  • No contraindications for the surgery;
  • Profession/job/vocation does not stop you from having this procedure.

Problems affecting healing

There are some medical problems that might affect healing and could make an individual a poor candidate for laser vision correction.  These conditions can include:

  • Lupus;
  • Collagen vascular diseases;
  • Rheumatoid arthritis;
  • HIV.

These associated diseases might influence wound healing properly, which is needed to achieve a good result.

Certain conditions

Some eye problems such as eyes that are dry, irregular astigmatism, Sjogren’s syndrome, thin corneas or keratoconus might also make the procedure not appropriate for you.

Designed for

This laser correction is developed to eliminate or reduce the need for contacts or glasses.  Although many people can function well with no glasses or contact lenses, some still need optical correction for some tasks.  Additionally, laser surgery does not change the problem known as presbyopia, a common problem with doing any close work and occurs when a person reaches the age of 40.  There are monovision surgeries, involves one eye corrected for close up vision and the other for seeing far away as an option to reduce presbyopia.

Most commonly performed

LASIK is the commonly performed refractive laser surgery. It involves cutting a very thin flap in the cornea, folding it back on its hinge and then an excimer laser is used to vaporize a small amount of corneal tissue.  The flap is then placed back into position.

Other technologies

Like all technologies, Lasik and other laser surgeries continue to get better.  Currently there are ways to adapt the process of laser removal of the corneal tissue to match each person’s eyes, making results better and more predictable, with fewer side effects visually.


Photo-refractive keratectomy involves using this laser method without making the usual Lasik flap.  This technology came first before Lasik surgery but was replace by Lasik, now it is making a come-back as a favourable choice for those patients having thinner corneas or pre-existing dry eyes.
