People usually associate Lasik with only one Lasik vision correction method. In fact, Lasik now encompasses several surgical approaches with quality differences in vision direct improvement. The cost of Lasik also varies considerably.

If you're considering Lasik vision correction surgery on your eyes, bear in mind that this entails a significant investment on your part. Unless you get financing, you may have to cover the costs yourself, since the costs of Lasik vision correction are generally not included in dental and vision insurance coverage.

You may have learned about cut-rate prices for Lasik surgery. The ads announce low price, but they don't mention that such prices are applicable only to those who have minimal vision problems and have no astigmatism. The presence of astigmatism can make Lasik vision correction more expensive.

For Lasik vision correction to be truly effective, consider that until recently, ophthalmologists could only measure your eye as a whole, and they based their prescription for lenses on that average measurement. Traditional Lasik simply replicates the power of vision obtainable with corrective lenses based on one overall prescription for each eye.

More recent Lasik vision correction technology recognizes that your eye is not perfectly shaped thus each spot would need its own prescription. You can never get that degree of detail with lenses. The lasers divide your cornea into several hundred smaller sections, measure each section for its individual prescription, and subsequently perform individual corrective treatments for each spot.

The new instruments also enable a better measurement of your pupil in the dark (without shining a light into your eyes). This helps to correct one problematic aspect of traditional Lasik where patients report poor night-time vision and haloing.

The power of vision you get after such Lasik vision correction surgery is better than the vision you get with traditional Lasik. You may spend more for it, though.
