What is wavefront-optimized LASIK?
Wavefront-optimized LASIK is the type of laser treatment available on the Wavelight laser. This treatment is also based On the patient’s eye power and also takes into account corneal curvature and thickness, and applies laser energy in a unique fashion in the periphery of the cornea. This laser has been found to reduce the aforementioned complications such as glare, halos, and other nighttime visual aberrations that can occasionally occur with conventional treatments.
What is wavefront-guided LASIK?
Wave front-guided LASIK, also referred to as custom LASIK or wave front LASIK, is similar to conventional LASIK, except that in addition to treating a patient's basic refractive error, specific alterations in a patient's eye (high order aberrations) can also be treated. In wave front-guided LASIK, special mapping is performed prior to the surgery to identify any small irregularities in the patient's optical system. When these irregularities are severe, they can affect vision quality, contrast sensitivity, and night vision. When significant irregularities in a patient's wave front mapping are found, wave front-guided LASIK can be used, and the treatment will be based on the wave front-map generated.
What is Epi Lasik?
It is a procedure, which combines the advantages of PRK and LASIK, Epi lasik involves the use of a microkeratome, similar to LASIK, however only the superficial epithelial layer of cornea is separated as in PRK and this flap is replaced following the reshaping of the cornea using the Excimer Laser.
Will my vision improve immediately?
You should be able to see reasonably well within a few days after your procedure. If you have had a SURFACE PRK procedure, your vision may fluctuate for the next 1 to 3 months and reading fine print may be difficult. If you have had a LASIK procedure, your vision is likely to stabilize around a month after the procedure.
What are the possible side effects of the procedure?
Early side effects of any corneal procedure include light sensitivity, glare and foreign body sensation in the eye. Both SURFACE PRK and LASIK can sometimes result in under correction or incomplete removal of the refractive error. Occasionally, an overcorrect ion eg., the correction of more myopia than intended, can also occur. A change in the clarity of the corneal tissues – termed corneal haze – can also occur in some patients.
How do I know if I am a suitable candidate for Lasik?
A large percentage of nearsighted, farsighted, and astigmatic patients are potential candidates for LASIK. Patients who are 18 years of age or older, have healthy eyes that are free from retinal problems, corneal scars, and any eye disease are suitable. Along with being medically suitable, the best candidates are people with a lifestyle or occupation in which they are dissatisfied with their contact lenses or glasses. By having an evaluation, examination, and consultation with you, the doctor will be able to determine if you are a good candidate.
