Brief Background of Allegretto Lasik Vision Correction
The Allegretto laser is an extremely fast and accurate laser that uses a new concept in laser vision correction procedures, called wavefront optimization.
According to a Los Angeles lasik surgeon, this laser has justly developed a reputation as having some of the best results of any laser used in the world to deliver low re-treatment rates, minimal glare and halo side effects, and excellent eye tracking, centration and laser treatment profile technology.
It uses invisible ultraviolet (UV) light pulses to remove precise amounts of corneal tissue from the eye to reduce or eliminate farsightedness and astigmatism (distorted vision)
How does Lasik it work?
The Lasik system treats farsightedness by removing tissue from the outer areas of the cornea to make it steeper.
It treats astigmatism by flattening the central cornea by different amounts and at different locations to correct uneven focus.
When is Lasik used?
Eye surgeons say that the laser system is intended for the LASIK (Laser-Assisted in Situ Keratomileusis) treatment of patients who:
- have farsightedness up to +6.0 diopters (D) and astigmatism up to 5 D with a maximum manifest refraction spherical equivalent (MRSE) of +6.0 D
- are 18 years of age or older, and
- have had stable eyesight for the year prior to the pre-operative examination.
What will it accomplish? Allegretto laser treatment is intended to reduce or eliminate farsightedness and/or astigmatism.
Side effects of Allegretto Lasik
- glare from bright lights
- halos (rings around lights)
- light sensitivity
- night driving glare, and
- visual fluctuation
When should Lasik not be used?
The Lasik laser system should not be used on patients who:
- are pregnant or nursing
- have a collagen vascular disease (such as rheumatoid arthritis or scleroderma)
- have an autoimmune or immunodeficiency disease (such as AIDS or cancer)
- show signs of keratoconus (an eye disorder in which there is a thinning of the cornea that results in blurred or distorted vision), or
- are taking medications with visual side effects (such as Accutane or Cordarone)
