LASIK stands for laser assisted in-situ keratomileusis. This is a highly popular form of eye surgery and is used to correct a range of refractive errors, such as astigmatism, myopia and hyperopia. LASIK is a type of refractive surgery and involves controlled and precise targetting of the corneal tissue with a special laser. Corneal tissue is removed, resulting in a reshaping which enables improved vision
TYPES OF LASIK
CONVENTIONAL LASIK SURGERY
It corrects only spectacle number but does not correct any other distortion.
OPTIMIZED LASIK SURGERY
It corrects spectacle number and optimized correction of distortions to maintain a prolate natural like cornea, thus giving better vision at night and dim illumination.
Wavefront-optimized LASIK, is an enhanced version of conventional LASIK. It does not address pre-operative HOAs, but the laser ablation is adjusted, based on the patient’s eye glasses prescription, to minimize any increase in spherical aberration induced by the treatment.
So whereas the goal of wavefront-guided LASIK is to identify and treat multiple HOAs (including spherical aberration) and refractive error during the corneal reshaping of the eye, the goal of wavefront-optimized LASIK is only to limit any increase in spherical aberration during the treatment of refractive error by the laser.
What Is Custom Lasik?
Custom LASIK is a procedure that involves the use of a wavefront analyzer which helps the surgeon to customize the LASIK procedure to every individual eye. Customized procedure enables a person to see clearer and shaper than before and thus improves the quality of vision.
Custom LASIK uses an equipment called the wavefront analyzer (aberrometer) to accurately measure the way light travels through the eye. The resulting map of the eye is then programmed into the laser, which then treats the eye, based on the personalized 3Dmap. Custom LASIK helps to treat “higher order” aberrations,which are tiny imperfections in the optical system of the eye. They have a significant impact on the quality of vision especially at night . In fact, higher order aberrations are not treatable with contact lenses, glasses or conventional LASIK.
Why Go For Custom Lasik Procedure As Compared To Conventional Lasik ?
The procedure for both custom LASIK and Conventional is the same but the pre assessment tests differ greatly. The wavefront analsyer used with custom LASIK brings a whole new level of knowledge and accuracy for the surgeon to perform this advanced procedure. This treatment has a significant impact on quality of vision and eliminates the problem of glare and halos at night. Topography, Aberrometry and Pachymetry are pre-operative tests required.
