摘　　要：Purpose:The aim of this systematic review was to synthesize and appraise the evidence of the benefits of presbyopic correction on the cornea for visual function.Summary:Comprehensive search was conducted in MEDLINE using keywords like“presbylasik”,“presbyopic refractive surgery”,“corneal pseudoaccommodation”and“corneal multifocality”.We reviewed corrected and uncorrected visual acuities for distance and near(uncorrected distance visual acuity(UDVA),uncorrected near visual acuity(UNVA),corrected distance visual acuity(CDVA),distance corrected near visual acuity(DCNVA),corrected near visual acuity(CNVA)),along with the refractive outcomes in spherical equivalent(SE)and astigmatism comparing the differences observed between preoperative myopic and hyperopic patients,as well as among techniques.Thirty-one studies met the inclusion and quality criteria.Monovision provides excellent distance and near uncorrected acuities,but with a 17%retreatment and a 5%reversal rate.Initial multifocal ablations result in 12%loss of 2 or more lines of CDVA,and a 21%retreatment rate.Laser Blended Vision provides excellent UDVA,but with a 19%retreatment rate.Initial experiences with Supracor show moderate predictability and a 22%retreatment rate.Intracor results in 9%loss of 2 or more lines of CDVA.KAMRA provides excellent UDVA,with only a 1%retreatment rate,but a 6%reversal rate.Initial experiences with PresbyMAX provided excellent UNVA and DCNVA,showing excellent predictability and a 1%reversal rate.Conclusions:The findings have implications for clinicians and policymakers in the health-care industry and emphasize the need for additional trials examining this important and widely performed clinical procedure.
