AMO Custom Wavefront Guided Procedure – Why is it the treatment of choice for your eyes?
The custom treatment Kelowna Laser Vision offers is a marriage of two innovative technologies: the Wavescan Wavefront Diagnostic System and the Star S4 IR™ Laser Platform. Using the Wavefront Diagnostic System, our experts map your eyes to obtain a prescription individual to you. We then use the advanced Star S4 IR Laser to correct your vision precisely to that prescription. This diagnostic and treatment system combined allows us to locate and correct the unique anomalies of each eye for maximum vision improvement.
At Kelowna Laser Vision we recommend the Custom Wavefront Guided procedure. Medical studies show that this technology gives patients the potential for better overall clarity of vision than with glasses or contact lenses, enhanced night vision, and better vision than laser surgery with conventional or optimized laser procedures. The published studies also show significantly lower retreatment rates for custom wavefront guided procedures than with optimized or conventional procedures.
The Wavescan Wavefront Diagnostic System – Technology that makes a difference.
The Wavescan, AMO’s exceptional wavefront aberrometer, measures the refractive error and all imperfections of the human eye at an unprecedented level and provides:
- Precision: 25 times more precision than standard methods of refractive error measurement.
- Fourier based wavefront calculations: delivers the highest resolution available of the wavefront error. It accurately reconstructs the wavefront image for treatment.
- Acuity Maps®: Chart the optical imperfections of the eye.
- Point Spread Function: Demonstrates how a patient would see a point source of light.
The Star S4 IR Laser – Why it’s Technology Matters to You
AMO’s latest excimer laser system represents the most advanced laser technology platform available. Integrating data collected by the WaveScan System, the Star S4 IR utilizes these patented and proprietary technologies:
- ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements and aligns laser pulses in precisely the correct location regardless of patient eye movement during surgery. This means you do not have to hold your eye perfectly still, but can relax, knowing your treatment is precisely centered on your eye.
- Iris Registration (IR): The first FDA-approved, fully automated method of rotational alignment of wavefront data to the correct corneal location. This is very important to ensure the treatment of all aberration, especially astigmatism and high order aberration is in proper position. It also compensates for changes in pupil center position (call pupil centroid shift) under different lighting conditions. This reduces the possibility of decentered treatment.
- Variable Spot Scanning (VSS): Variable laser beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area. This conserves corneal tissue and allows for faster treatment times.
- Variable Repetition Rate (VRR): VRR delivers treatment at varying repetition rates, optimizing treatment time. Less energy build-up is needed for small laser spot sizes allowing laser pulses to be applied faster, thus decreasing the overall time for treatment.
