subject: The Technology Of Wavefront Lasik Eye Treatment [print this page] Wavefront technology is a subset of standard lasik laser eye treatment. In regards to lasik, before operation commences a screening test is used to ensure your suitability. Aside from improving the success rates of laser eye surgery, the screening tests also help regulate the crucial parameters for setting up the operation.
With standard lasik, your preoperative prescription is the main factor considered when setting up the excimer laser used to vaporise the cornea. The issue with this is your spectacle prescription assumes the front surface of the eye, as well as the other optical surfaces throughout the eye are regular and perfectly smooth.
In reality, everyone's eyes are different. For instance, alike prescriptions in both the right and left eye, upon near analysis, will uncover minor inconsistencies.
Wavefront technology is a system of laser eye treatment which takes into account "higher order aberrations". Essentially, this means the way the front of the eye scatters light is observed and considered when the process of lasik is applied.
Wavefront analysis is done in the screening process. An instrument called aberrometer is used to execute 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.
The common and many symptoms associated with standard lasik are minimized with wavefront laser eye operation. Symptoms normally experienced with laser eye treatment include night time haloes and glare. This is especially concerning when driving at night and much more noticeable when there is rain or fog. With the precision used in wavefront operation, this unnerving symptom is minimised.
Another widespread issue with lasik eye operation is the postoperative vision. While 20/20 is usually known as "prefect sight", you may not achieve this with standard lasik eye operation. Wavefront guided operation ensures you the best chance of achieving this level of vision after refractive surgery.
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 amount of cornea affected is decreased which means that even those with thin corneas can now be considered likely candidates. Surgery results are very successful and 20/20 vision is now becoming a reality.
After wavefront lasik surgery, the usual post operative care is applied. Antiobiotics and lubricants to stop dry eyes and irritation are given by ophthalmologists. Regular visits to your laser eye clinic will be scheduled to ensure the healing process is steady and post operative complications are not seen. A small amount of people need a second process to well-defined up any residual prescriptions which may be apparent. The second operation is often done within the first six months of the lasik eye treatment.
