Custom Lasik, also known as wavefront LASIK, is
an advanced form of lasik surgery that can produce sharper vision than traditional,
non-wavefront LASIK. To recognize the importance of custom LASIK, it's vital to
know that every eye is unique and that the human eye is not an ideal optical
system. Most patients are aware of three vision problems, i.e. farsightedness,
nearsightedness and astigmatism. However, nearly, every eye also has subtle
optical errors known as higher order aberrations. These have less known, even
strange names such as coma, aberration and trefoil. Though, it's predicted that
higher order aberrations characteristically account for no more than 10% of the
total refractive error of an average eye, these slight eye defects contribute
to halos, glare, starbursts and other vision problems, particularly in low
light situations, such as driving at night.
Higher order aberrations cannot be noticed by
the tests carried out in a conventional eye exam. Even if the eye specialist
makes use of automated instruments to decide your eyeglasses prescription, it's
quite possible that these instruments only measure farsightedness,
nearsightedness and astigmatism. Foe detecting and measuring high order
aberrations, an advanced technology known as wavefront analysis is required. A
wavefront is typically a three dimensional representation of the optical
quality of a beam of light. If the optical quality of the light beam is
'ideal', i.e. it has not been tainted by
aberrations in an optical system, the wavefront is flat. When the optical
aberrations distort the light beam, the wavefront has a disrupted shape.
Wavefront
Guided LASIK
Wavefront guided LASIK, also known as custom
LASIK or wavefront LASIK, is same as traditional LASIK, except that in addition
to treating a patient's basic refractive error, particular alterations in a
patient's eye can also be treated. In this form of treatment, special mapping
is carried out before surgery to recognize any small indiscretion in the
optical system of the patient. When these indiscretions become severe, they can
affect the quality of vision, night vision and contrast sensitivity. When
significant indiscretions in a patient's wavefront mapping are noticed, advanced wavefront LASIK surgery India
can be used and it will be based on the wavefront map generated.
Better
Night Vision
A recent report released stated the findings of
a study that made comparisons between the night driving vision of the patients
who underwent custom LASIK with that of the patients who underwent traditional
LASIK. The wavefront LASIK that the first group of patients underwent was an
all laser process, with the corneal flap built with a femtosecond laser. The
conventional LASIK process for the second group of patients was a single laser,
traditional procedure, with the corneal flap built with a hand held bladed
microkeratome. Vision test was carried out with a night driving simulator which
stated that patients who underwent all laser, wavefront guided LASIK scored
much better on the night driving simulator tests after surgery than they did
before. On average, these people could detect and identify objects from a
greater distance after the process than they could while wearing corrective
lenses before surgery.
Visual recovery after the custom best lasik eye surgery India is usually
the same as the recovery time after LASIK that doesn't involve wavefront
technology. Generally, vision steadies within a few weeks after surgey, though
it might take longer in some cases. Remember, to carry out this surgery in the best LASIK center in Pune for better
results.
