| Summary: |
Much has changed in the
field of refractive surgery in the last decade. The
previous techniques– radial keratotomy and PRK was
replaced by newer techniques – LASIK, LASEK and
Epi-LASIK. Many developments in laser technology,
improvments in laser algorithms and eyetracking systems,
introduction of topography and wavefront guidance
systems have greatly improved visual outcomes, enabled
correction of higher refractive errors and resulted in
less complications. Nowadays surgeons can choose from a
range of techniques, microkeratomes, laser technologies
(broad beam, scanning slit, flying spot). There is
available a new fetomsecond laser for creation the most
predictable corneal flap. The new wavefront and
topography guided system have helped designed better
individualised profile of ablation making possible to
correct a higher optical aberrations. Surface ablation
techniques-LASEK and Epi-LASIK attempt to minimise the
pain and potential for haze of conventional PRK. Phakic
IOLs and refractive lens exchange are methods of
treatment of high myopia and hyperopia. There is no
ideal method for correction of hyperopia. Photoablative
procedures are only useful for lower amounts of
hyperopia, thermal keratoplasty has low level of
predictability and high level of regression and hyeropic
eyes are often unsuitable for phakic IOLs. This paper is
focused on the current status of available technologies
for refractive errors correction. |
