Wavefront Lasik Surgery

What is wavefront-guided LASIK?

Wavefront-guided LASIK, also named as custom LASIK or wavefront LASIK, is like conventional LASIK, except that in addition to addressing a patient’s basic refractive error, particular adjustments in a patient’s eye can in addition be treated.

In wavefront-guided LASIK, specialised mapping is carried out before surgery to discover any little abnormalities in the patient’s optical system. Once these irregularities are serious, they can impact upon vision quality, contrast sensitivity, and night time vision. Once significant irregularities in a patient’s wavefront mapping are ascertained, wavefront-guided LASIK could be applied, and the treatment will be grounded on the wavefront-map generated.

What other types of refractive surgery are obtainable?

Additional types of refractive surgery are accessible and may be more advantageous than LASIK for certain persons.
Advanced surface ablation: There are a range of other methods that use the excimer laser to reshape the cornea in much the same means as LASIK, but without the creation of a corneal flap. These are generically termed advanced surface ablation (ASA) and include photorefractive keratectomy , laser subepithelial keratomileusis (LASEK), and epipolis laser in situ keratomileusis (Epi-LASIK).

All of these techniques call for first taking away the most superficial corneal layer (epithelium) and and so doing excimer laser ablation.

Phakic intraocular lenses, For patients with extreme shortsightedness, LASIK and sophisticated surface ablation are not sensible options. In these instances, a phakic intraocular lens possibly be used. This lens is imbedded inside the eye and can effectively address nearsightedness up to -20 diopters.

Conductive keratoplasty: Conductive keratoplasty (CK) is a process that can be applied for the impermanent rectification of hyperopia or presbyopia. CK necessitates using radiofrequency waves in the peripheral cornea to make peripheral corneal shrinkage and central steepening. This routine is very safe, but its consequence is often not long-lasting, and simple regression is common after a few years
