Wavefront technology measures the unique way the eye processes light. During a wavefront eye exam, a computerized instrument called an aberrometer analyzes how light travels through the eye and creates a unique map, which is sometimes referred to as a "fingerprint" of the eye because no two are the same. This map, which was first used in wavefront-guided LASIK, can now be used to create customized, high definition lenses that account for all vision errors.
What lenses with wavefront technology treat
Wavefront-guided lenses treat both lower order and higher order aberrations.
Lower order aberrations include:
Higher order aberrations refer to other vision errors such as:
While conventional lenses only correct for lower order aberrations, lenses created using wavefront technology correct for higher order aberrations as well. The high definition lenses created using wavefront technology can be used to treat anyone who needs corrective lenses.
Benefits of lenses created using wavefront technology
Lenses created using wavefront technology address lower order aberrations as well as higher order aberrations that couldn't previously be addressed with corrective lenses. Now individuals can achieve clearer, crisper vision with glasses or contacts. Since wavefront-guided lenses address vision problems such as glare and halos, they can greatly improve night vision. Wavefront-guided lenses can also be beneficial for those who had a refractive procedure such as LASIK, but still have vision problems that conventional lenses are not able to address.
Problems with lenses created using wavefront technology
One drawback of wavefront-guided lenses is the cost, as they are typically 25 to 30 percent more expensive than conventional lenses. Also, since wavefront technology is still relatively new and requires special equipment, not all eye doctors offer it, so be sure to ask before you schedule an appointment.
