ResourcesConventional, Optimized vs CustomVue Treatments? |
"Conventional" Treatments |
|
Conventional treatments are based upon measurements obtained from the tried and true phoropter instrument. This is the instrument that you sit behind and answer the seemingly endless stream of questions, "Which is better one or two?" that ultimately allow us to determine your eyeglass prescription in terms of nearsightedness, farsightedness, and astigmatism. This data is then entered into the laser's computer for your treatment. We have treated over 10,000 eyes with conventional technology, and although this was groundbreaking technology at one time, Hale Vision's mission is to deliver the highest quality vision correction care available at all times and this is now represented by iLASIK and wavefront guided laser treatments provided by the Visx S4 IR laser system. |

CustomVue Treatments |
 On May 23, 2003 the FDA approved the VISX Wavefront Guided CustomVue laser vision correction treatment and set a new standard for vision correction, with the potential to enable better vision than contacts or glasses, even at night.CustomVue treatments are based upon measurements obtained from the VISX WaveScan aberrometer, a new diagnostic system that captures a "fingerprint" of the eye which is 25 times more precise than what was previously measurable by the conventional phoropter method. In addition, the WaveScan evaluates more than nearsightedness, farsightedness, and astigmatism, as it captures other, more specific imperfections in each individual's vision. This data is then used to generate an individualized CustomVue treatment. Since its' introduction, wavefront-guided CustomVue treatments have become the new gold standard of excimer laser refractive treatments. We have experienced a definite increase in 20/20 postoperative uncorrected visual acuities and an almost doubling of patients seeing 20/15 or better after surgery. It has also been determined that a patient is ten times less likely to complain of night vision issues following customized treatments vs. the older conventional treatments. |
| In August of 2005, SIGHTLab, our state-of-the-art surgical facility, became the first facility in Wisconsin to use the new Visx Star S4 Iris Registration system. This system utilizes infrared technology to map the individual characteristics of the human iris during the analysis portion of the patients' workup. |

Rotation can occur when the patient changes from the seated to the lying position. This can result in a misalignment of the laser treatment pattern. |
| When the patient is positioned under the laser for treatment, another infrared camera compares those characteristics and aligns the treatment pattern to adjust for the normal eye rotation that occurs when a patient shifts from the seated position to the lying position. |
|
The Iris Registration system recognizes and corrects and misalignment in the laser treatment pattern. |
| Even fairly small rotations can degrade the effect of the laser treatment and, subsequently, the quality of the patients' visual result. |
|
Image degradation occurs when the treatment is not properly aligned. The lower row shows the effect on the image quality with increasing rotation from 1 to 30 degrees. |
"Optimized" Treatments |
|
Another type of laser refractive treatment is called "Optimized" or "Wavefront Optimized". This treatment represents a hybrid between Conventional and Custom Wavefront Guided treatments. The Optimized treatments are based off the traditional phoropter measurements and NOT from an aberrometer as are wavefront guided treatments. An optimized treatment is a conventional treatment "optimized" by the addition of a spherical aberration adjustment (one of the many higher order aberrations measured by an aberrometer). This correction factor is obtained by population based data and not any measurement of the patient. This treatment will usually represent an improvement over the "Conventional" treatment unless the patient is one of a small percentage of the population with an unusual spherical aberration for their age and can then lead to problems postoperatively. You should ask specifically whether you are having a "wavefront guided" versus a "wavefront optimized", or even a conventional treatment as they are not of the same quality and often patients are misled to believe they are receiving the "latest" technology. |
