Wavefront Lasik Eye Treatment Technology
Wavefront technology is a subset of standard Lasik laser eye treatment. With Lasik, a screening test is conducted prior to surgery to guarantee an individual’s suitability. Aside from improving the success rates of laser eye operation, the screening tests also help fix the essential parameters for setting up the operation.
For standard Lasik procedures, the preoperative prescription is the most significant component considered when setting up the excimer laser that will be used to vaporize the cornea. With the spectacle prescription, it assumes that all surfaces of the eye, front and other optical surfaces, are regular and precisely smooth.
The truth is, no two individuals have the same eyes. Even if you have the same prescription in your right and left eye, there are slight inconsistencies when comparing the two closely.
With wavefront technology, “higher order aberrations” are taken into account in this manner of laser eye treatment. Essentially, this means the way the front of the eye scatters light is observed and considered when the operation of Lasik is applied.
The screening process involves wavefront analysis. An instrument called aberrometer is used to perform such test. By taking into account the small discrepancies over the front of the eye, a “fingerprint” of the eye is created and greater precision in laser eye treatment is employed.
With wavefront laser eye operation, many symptoms noticed with standard Lasik are minimised. The most generally observed symptom with laser eye treatment is haloes and glare at night time. This is especially concerning when driving at night and much more noticeable when there is rain or fog. Because of the precision of wavefront surgery, this unnerving sign is minimized.
Another usual issue with Lasik eye operation is the postoperative sight. “Perfect vision” or 20/20 visual acuity is not often achieved with standard Lasik eye surgery. Surgery guided by wavefront engineering is the best assurance this level of visual acuity after refractive surgery is achieved.
If your corneas (front of the eye) are extremely thin, standard Lasik is not suitable. With wavefront technology, the ablation or vaporisation is better controlled. The portion of cornea affected is decreased which means that even those with thin corneas can now be considered possible candidates. Surgery results are very successful and 20/20 vision is now becoming a reality.
Similar post surgical attention is also applied after an individual undergoes wavefront Lasik surgery. Your ophthalmologist will give you antibiotics as well as lubricants to stop symptoms of dry eye and discomfort. To guarantee that the healing process goes as expected and that post operative complications are prevented, repeated visits to the laser eye clinic will be scheduled. A small amount of people need a second process to clearly up any residual prescriptions which may be apparent. This is generally done within the first 6 months after Lasik eye treatment.
