What is Wavefront-Guided LASIK?
Also known as ‘custom’ LASIK, Wavefront-guided LASIK tailors the laser eye surgery to specific alterations in a patient’s eye. Your eyes are unique, much like your fingerprints, and Wavefront mapping can chronicle the details minutely.
It’s based on your prescription, but also takes into account corneal curvature and thickness, and applies laser energy in a unique fashion around the periphery of the cornea.
Treats Higher-Order Aberrations
It’s essentially similar to conventional LASIK but has a major added benefit – in addition to treating a patient’s basic refractive error; specific alterations in a patient’s eye (high order aberrations) can also be treated.
In wavefront-guided LASIK, special mapping is performed before surgery to identify irregularities in the patient’s optical system. When these irregularities are severe, they can affect vision quality, contrast sensitivity; night vision; glares and haloes that can sometime occur after conventional laser eye treatment.
When significant irregularities in a patient’s wavefront mapping are found, wavefront-guided LASIK can be used, and the treatment will be based on the wavefront-map generated.
Other types of refractive surgery
The type of laser eye surgery you need depends on your particular vision issue; your overall health; underlying medical issues and the thickness of your corneas. Optilase perform a comprehensive consultation to ensure the appropriate treatment recommendation for you.
Advanced surface ablation: There are a variety of other techniques that utilize the excimer laser to reshape the cornea in much the same way as LASIK, but without the creation of a corneal flap.
These are generically termed advanced surface ablation (ASA) and include photorefractive keratectomy (PRK), laser subepithelial keratomileusis (LASEK), and epipolis laser in situ keratomileusis (Epi-LASIK).
All of these techniques involve first removing the most superficial corneal layer (epithelium) and then performing excimer laser ablation.
KAMRA and Presbia are two options for patients with age-related degeneration of their reading vision; both methods involve the placement of a corneal inlay/onlay to eliminate dependence on reading glasses for close vision.
