Abstract
Four hundred one eyes of 219 patients underwent laser in situ keratomileusis(LASIK) at Kangbuk Samsung Hospital from March 1997 to June 1998. Of those, 33 eyes of 25 patients were retreated. Among 33 eyes, we presumed that 3 eyes had decreased visual quality mainly associated with decentration. The mean reftactive error and the amount of decentration of 3 eyes were -1.00 diopter and 2.66mm. After retreatment of these 3 eyes, uncorrected and corrected visual acuity, and visual quality were improved by correction of residual refractive errors, even though the amount of decentration was the same. In cases of decreased visual quality which is suspected to be mainly associated with decentration, we need differentiation between decentration and residual rfractive errors as causes of decreased visual quality. Even though decentration is suspected as a cause of decreased visual quality, visual quality can be improved by correction of residual refractive errors.
Key Words: Decentration;Laser in situ keratomileusis;Residual refractive errors;Visual quality
