Attention is a phenomenon hard to define, but can be conceptualized as a mental function ranging from sustaining readiness to perceive stimuli to understanding the nature and value and selecting stimuli that are most relevant to the given situation. Manifestations of attention include vigilance, and focused, directed, selective, divided, and sustained attentions. While basic attentional tone is controlled by the interaction among reticular activating system, thalamus, and prefrontal cortex, direction and selection of attention is controlled by neural circuits of prefrontal, posterior parietal, and limbic cortex. It is expected that understanding of attention and its neural could provide answers to the relationship between pathophysiology and clinical symptoms of some major psychiatric disorders. More effort are required to develop tools to assess more detailed and various aspects of attention in Korea.

We evaluated the effect of retreatment for under- of overcorrection after laser in situ keratomileusis(LASIK). We performed LASIK enhancement after lifting flap(8 eyes) and transepithelial PRK(1 eye) for the 9 eyes of undercorrection and 1 eye of hyperopic correction after primary LASIK procedures were performed from October 1996 through May 1997. The average preoperative refractive error was -12.88D and preretreatment refractive error was -3.53D in spherical equivalent. The average period from primary LASIK to retreatment was 85.7 days and we evaluated the stability, predictability, efficacy, safety, and complications after 6 months. At 6 months postretreatment, the average refractive error was -0.31D and 8 eyes obtained a refraction within +/-1.0D of emmetropia. Uncorrectedvisual acuity(UCVA) was improved from 0.24 to 0.71. There was one eye with grade III corneal haze and decentration after transepithelial PRK on corneal flap. And it had 1 line loss of best corrected visual acuity(BCVA) compared with preretreatment BCVA. The final average refractive error of the 7 eyes which underwent retreatment after 1 month was closer to emmetropia than that of the other 3 eyes which underwent retreatment within 1 month, but there was no statistically significant difference(p>0.05). In conclusion, LASIK tetreatment may be considered for the correction of under- and overcorrection after LASIK.
