CustomLASIK uses the wavefront analyzer which brings a whole new level of knowledge and accuracy to your procedure.
The wavefront analyzer is used to acurately measure the way light travels through your cornea and the laser treats your cornea based upon that personalized 3D map and your prescription.
CustomLASIK helps to treat "higher order" aberrations, which are tiny imperfections in the cornea that can have a significant impact on one's quality of vision. In fact, higher order aberrations have been linked to visual glare and halos. These minute corneal imperfections are not treatable with glasses or conventional LASIK.
Optimal results require precise alignment of the laser treatment - which is why Iris Registration is so important. By linking diagnostic wavefront information with the treatment itself during the Advanced CustomVue procedure, Iris Registration provides a much higher level of alignment accuracy and precision, giving the surgeon confidence that the treatment will be placed in the correct location.
Registration + Resolution
The AMO WaveScan WaveFront™ System leads the industry for outstanding wavefront acquisition and diagnostic capabilities. Fast and powerful, the WaveScan System delivers unprecedented measurement accuracy, enhancing the precision of the Advanced CustomVue™ procedure.Using AMO Fourier algorithms, WaveScan captures the unique imperfections of each patient's eye using 100 percent of the available Hartmann-Shack data points for more accurate wavefront error reconstruction. The system provides the highest resolution available for any shape pupil, enabling precise, individualized treatment for the broadest range of visual imperfections.
Personalizes the Advanced CustomVue™ treatment for each patient.
During treatment delivery, Iris Registration:
- Finds and unwraps the iris in preoperative and operative images.
- Selects prominent reference points.
- Applies a set of sophisticated algorithms to find multiple matching reference points for each iris.
- Calculates the ablation torsional angle from multiple matching reference points, and adjusts the treatment positioning prior to ablation.
- Automatically checks the solution quality to help prevent false matches.
Optimal Outcomes With Iris Registration (IR)
A patient's pupil center will move relative to the outer iris boundary in different environments. To minimize the impact of this movement, IR:
- Records the outer iris boundary at the WaveScan and laser.
- References the WaveScan pupil center to the outer iris boundary.
- Records the pupil center relative to the outer iris boundary and compares it under the laser to the WaveScan reading.
- Centers the laser ablation over the WaveScan pupil center.
