【摘要】目的 评价传导性角膜热成形术(CK)治疗衍射型多焦点人工晶状体植入术后正性屈光不正的临床效果.方法 回顾性病例研究.6例(7眼)植入衍射型多焦点人工晶状体后发生正性屈光不正的患者接受CK手术,手术采用CK View Point Refractec(RCS-200,Refractec,Inc.)系统.随访1年,观察患者远近视力、最佳矫正视力、脱镜率、屈光状态、角膜曲率等指标.CK手术前和术后1年远、近视力变化采用非参数秩和检验.结果 CK手术前患者中位数远视力为0.4,中位数近视力为0.25,平均等效球镜+1.10±0.29 D(+0.75～+1.50 D).CK术后1年,患者的中位数远视力为0.8,中位数近视力为0.5,平均等效球镜为-0.39±0.38 D(+0.25～-1.0 D).CK术后1年,患者远、近视力,与术前相比差异具有统计学意义(Z=-2.226,-2.375,P＜0.05).结论 CK可以安全有效地治疗白内障手术后轻度正性屈光不正,并且能提高衍射型多焦点人工晶状体植入术后的脱镜率.%Objective To evaluate the clinical results of conductive keratoplasty (CK) for correcting residual ametropia after multifocal apodized diffractive intraocular lens (IOL) implantation.Methods In this retrospective study,seven eyes of six patients underwent CK with CK View Refractec (RCS-200,Refractec,Inc.) for the correction of residual hyperopia after multifocal apodized diffractive IOL implantation.The
follow-up period was 12 months and uncorrected distance visual acuity (UCDVA),uncorrected near visual acuity (UCNVA),best spectacle-corrected distance visual acuity (BSCDVA),best distance-corrected near visual acuity (BDCNVA),best spectaclecorrected near visual acuity (BSCNVA),manifest refraction and central keratometry were measured and recorded.A nonparametric test was used to analyze the data.Results The median of UCDVA was 0.4,the median of UCNVA was 0.25,and the mean spherical equivalent (SE) refraction was +1.10±0.3 D (range +0.75 to +1.50 D) after cataract surgery and before CK.One year after CK,all eyes had from a UCDVA and UCNVA of 0.5 or better with a mean median UCDVA of 0.8 and a UCNVA of 0.5.The mean SE refraction was-0.4 D±0.4 (range +0.25 to-1.00 D).There were statistically significant differences in UCDVA and UCNVA,after CK surgery (Z=-2.226,-2.375,P＜0.05).Conclusion CK is an effective and safe approach to correct residual hyperopia in pseudophakic eyes with multifocal apodized diffractive IOL implants.
