e are two important elements of the critical first step in evaluating your visual pathway. The only way to truely assess your ocular health and determine if your eye is healthy enough to support laser vision correction is to visualize the retina (inner surface of the eye) through a dilated pupil. During this portion of the exam your prescription is re-measured to minimize any chance of over-correction. This allows a surgeon to accurately gauge levels of astigmatism, farsightedness, nearsightedness and presbyopia.
Fourier Based Wavefront Measurement
During the past few years, new and more refined techniques in laser vision correction have increased the safety and precision of the procedure. Wavefront technology allows surgeons to measure a person's refractive errror or prescription with increased accuracy which can be especially important for low light vision. To date, most experts would agree the most precise measurement of prescription is acquired with a Fourier based wavefront algorithm. All of Dr. Newman's patients are evaluated with this technology. This added detail about a person's individual refractive error is used to create a laser ablation profile which is unique to that particular eye which Dr. Newman uses to reshape the corneal curvature. True wavefront measurements are 25 times more precise than the measurements typically used to prescribe glasses or contacts.This technology can be especially helpful in patients who have problems with night vision.
True Wavefront Technology
True wavefront technology is not to be confused with "wavefront optimized" technology which does not directly measure a person's individual wavefront error. It instead relies on a treatment algorithm which blends the peripheral untreated cornea with the treated central cornea, and applies the same treatment to all patients. The simple difference between this technology and true wavefront measurement based technology is that the latter accurately measures an individual's higher order aberrations and creates the MOST detailed ablation profile possible for that particular eye. In general, the more detail you have about a person's prescription, the more accurate the correction will be leading to an increased probability of achieving the best vision possible. This can be especially helpful when trying to maximize night vision.

Lastly, and most importantly, we tailor the results to your individual needs. Our experience in identifying and targeting your visual potential with your visual requirements are designed to get you the most visual freedom with your customized lasik procedure. We realize vision is very personal and provide a one on one environment with the surgeon. With a 20 year career dedicated exclusively to laser vision correction and the personal experience of over 80,000 procedures, rest assured Dr. Newman has seen your individual prescription many times in the past. Couple this with vision technology that measures your vision 25 times more precisely than the exams you've had in the past for your glasses or contacts and you've got the foundation for the best results possible. In fact, FDA clinical trials of the Visx Customview laser system showed 98% of patients could see 20/20 or better and 100% could see 20/40 one year after their procedure, and four times as many participants reported improvement in their night vision compaired to glasses or contacts.
