An excellent question that probably isn’t asked often enough. Folks see the word ‘LASIK’ and generally assume all procedures are the same. However, they are not. If you really want to do your homework and be knowledgeable about a surgery that affects your eyesight, learning the difference is important.
First of all, LASIK is an acronym that stands for Laser-ASsisted In situ Keratomileusis. The basic procedure behind LASIK is simply that a laser is used to create a flap in the cornea. The cornea is then reshaped using one of different methods to return your eyesight to as close to 20/20 as possible.
An aberration of a lower order would be near-sightedness, farsightedness or astigmatism. An aberration of a higher order would be night blindness and other night vision problems such as seeing halos around lights. (Aberration is just a fancy doctor word for vision problem.) Most ophthalmologists agree that the traditional form of LASIK surgery is better suited to resolving the lower order vision problems, while custom LASIK can treat lower order and higher order problems equally well.
Now, to the differences. First, let’s look at traditional LASIK. Your existing vision prescription is the basis for the laser settings used to reshape the cornea, which is what defracts light so you see clearly (or not so much). Unfortunately, this method is not pinpoint accurate, so the results may be less than 20/20.
Custom LASIK, on the other hand, uses the relatively new wavefront technology. Wavefront technology is used much like a roadmap. The technology maps out an exact route for the laser to take so the results are predictable and much more accurate.
Both traditional and custom LASIK procedures are fairly quick, with recovery procedures and timelines being somewhat similar. Most patients are back at work within a day.
Keep in mind that this is a very basic description of the two types of procedures. You are strongly encouraged to discuss all of your laser vision correction options in detail with the LASIK surgeon you choose. If you are completely satisfied with the answers you get to all your questions, consider seeking a second opinion.
As with any field, not all laser vision correction surgeons are created equal. Some use old, out-of-date equipment that may mean a higher risk factor for you. Others use modern technology with state-of-the-art equipment and have a staff that is fully trained to provide you the best possible outcome and care possible.
This is your eyesight we’re talking about. Having what is considered for many to be an elective surgery is not something to be taken lightly. Go in knowing as much as you can, ask all your questions and be sure you feel completely comfortable with the surgeon you select.
