No two eyes are alike, and like your DNA or fingerprint, your vision is unique. For hundreds of years, glasses have been used to correct vision by eliminating one or more of the three basic elements of blurring; nearsightedness, farsightedness and astigmatism. However, advances in optics have demonstrated that these three basic elements are only part of the picture. There are tiny imperfections or distortions in every eye, even when the perfect glasses or contact prescription is used. To understand this further, imagine two people who visit the eye doctor and obtain exactly the same glasses prescription. Using standard laser correction, those two individuals would be treated with exactly the same laser treatment plan, despite the fact that their eyes each have a unique set of naturally occurring tiny imperfections and distortions. And while we have achieved excellent results by treating only these three basic elements (nearsightedness, farsightedness, and astigmatism), we can now offer even more.

Dell Laser Consultants offers the technological advantage of Custom wavefront-guided laser vision correction. Custom laser correction involves a diagnostic device that maps the entire optical path of your eye, including the tiny distortions and imperfections naturally present in all eyes. This is effectively a unique “fingerprint of your vision,” and provides us with extremely precise and detailed information about your vision. The technology involved is highly complex, and it is based upon mathematical techniques used to improve the performance and image quality of deep space telescopes. This customized unique map of your eye is then loaded into the computer of the excimer laser, which generates a wavefront customized treatment appropriate for the individual “fingerprint” of your eye.

Results of an FDA clinical trial of this technology demonstrated that an incredible 94% of patients treated were able to see 20/20 or better without glasses. Four times as many people in the trial were very satisfied with their night vision after LASIK, compared to their night vision before with glasses or contacts. These results are superior to those obtained with standard laser correction, and the dramatic improvement in night vision may be the greatest single advantage of Custom laser correction. Custom correction can be applied to both LASIK and Advanced Surface Ablation treatment.

You are probably already familiar with one application of wavefront-guided optical technology. In December 1993, Space Shuttle Mission STS-61 installed the COSTAR (Corrective Optics Space Telescope Axial Replacement) upgrade to the Hubble Space telescope to correct a spherical aberration in the lens system of the telescope. Spherical aberration is one of the main phenomena corrected by Custom wavefront guided laser correction.
