This represents a further step forward in enhancing the precision of laser refractive surgery. Spectacles, contact lenses and conventional lasik correct only sphero - cylindrical refractive errors. The human eye is known to suffer only sphero-cylindrical refractive errors. The human eye is known to suffer from numerous, minute optical imperfections, other than sphero-cylindrical refractive errors. These additional imperfections are measured by an instrument called an aberrometer and incorporated into the treatment procedure. Thus, the 'wavefront - guided' treatment becomes a 'customized or 'tailor-made' approach that refines the procedure to correct not only the refractive error but also the other aberrations of the individual eye.
