Tendency of excimer laser corneal refractive surgeries

Abstract

In next decade, the excimer laser corneal refractive surgeries will keep the role of main stream with the continuing development and employment of femto-second laser thin flap,advanced surface ablation, wavefront and topography guided ablation, eyeball online tracking,modified monovision for compensating presbyopia. Pre-operational screening and ruling out sub-clinical keratoconus is crucial for preventing corneal ectasia and secondary keratocouns after corneal ablations.In the correction of extreme high myopia, phakic IOL implantation seems to be superior in visual quality to excimer laser corneal refractive surgeries and can keep the intact corneal biomechanical structure, suggesting that it may be a better surgical option for the treatnent of such eyes.
