Today’s cure for refractive insanity is Wavefront guided laser treatments. So what exactly is Wavefront? That can be a complicated question to answer. However, remember how the Hubble telescope was out of focus when NASA first sent it into orbit. To correct the scientific blunder, optical engineers fitted the blurry Hubble with a Wavefront corrective lens and the new images were “out of this world” – well actually nearly out of this universe. Incredible space age stuff. Well, that same technology is what drives advanced wavefront guided laser vision correction.
Most normal eyes can experience some blur, glare or halo effects around lights or have some residual blur even with the best glasses and contact lenses. In addition, in the past, it would occasionally happen that post LASIK patients experienced an exaggerated effect of those same unwanted visual distortions. These problems are caused by small irregularities in the way that the light is bent or refracted by an optical system – problems that optical engineers refer to as higher order aberrations – things like coma, trefoil, spherical aberration, tetrafoil and a myriad of others that are only referred to through mathematical symbols.
