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 spectacle-corrected 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.
