摘　　要：●AIM:To analyze one year clinical outcomes and subjective rating of hybrid bi-aspheric multifocal central presbyLASIK with micro-monovision for correction of presbyopia and myopic astigmatism.●METHODS:Seventy-four eyes of 37 patients consecutively treated with presbyLASIK were assessed.The mean age of the patients was 43.8±3.0 y with a mean spherical equivalent refraction of-5.21±1.87 diopters(D)and mean astigmatism of-0.82±0.64 D.Visual acuity,manifest refraction,contrast sensitivity,aberrometry and patients’subjective rating were evaluated pre-and postoperatively.●RESULTS:At 1 y postoperatively(68 eyes of 34 patients),the mean spherical equivalent(SE)refraction in distance eyes was 0.06±0.05 D,whereas the achieved SE in near eyes was-0.83±0.05 D.Ninety-nine percent of eyes were within±0.50 D of target correction of SE.The binocular mean uncorrected distance visual acuity(UDVA)was 0.00±0.18 logMAR(20/20).Sixty-four percent of patients achieved 0.0 logMAR(20/20)or better of UDVA and 0.1 logRAD or better of UNVA as well.There was a binocularly loss of one line CDVA after surgery for only one patient(3%,1/34)and no patient lost 2 lines.The changes in binocular contrast sensitivity(CS)in all test conditions were not significant at any frequency after surgery.The changes of entire eye total higher order aberrations(tHOA)and spherical aberrations(SA)significantly higher in near eyes than in distance eyes.The overall satisfaction score for surgery was 93±8.●CONCLUSION:The hybrid bi-aspheric multifocal central presby LASIK with micro-monovision appears to be an efficacious option for myopic presbyopes.One year postoperative outcomes in a relatively young presbyopia population indicate improvements in both far and near vision with high satisfaction.● AIM: To analyze one year clinical outcomes and subjective rating of hybrid bi-aspheric multifocal central presbyLASIK with micro-monovision for correction of presbyopia and myopic astigmatism.● METHODS: Seventy-four eyes of 37 patients consecutively treated with presbyLASIK were assessed.
