• PURPOSE: To determine the visual efficacy over a 6-month follow-up period for the Eyecryl Actv DIYHS600ROH, a diffractive-refractive multifocal intraocular lens (IOL).

  SETTING: Beyoğlu Eye Research and Training Hospital, Istanbul, Turkey.

  METHODS: In this single-centre, observational, retrospective study, we reviewed 13 patients (26 eyes) aged from 41 to 79 years who were treated with a diff ractive refractive multifocal IOL (Eyecryl Actv DIYHS600ROH, Biotech Vision Care Pvt. Ltd., India). Near, intermediate and distance visual acuity outcomes were assessed at 1 week and 1, 3 and 6 months after the second eye surgery.

  RESULTS: The preliminary results showed an overall reduction in refractive error from preoperative to postoperative. At 6 months, residual sphere was 0.076 dioptres (D) (range 0.75 to −1.25 D) and residual cylinder was 0.61 D (range 0 to −1.75 D). There was also a marked improvement in dynamic visual acuity from the preoperative assessment, which continued until slightly over the 6-month period (re-ANOVA p<0.001).

  CONCLUSION: The results of this preliminary study showed a marked improvement in distance vision when preoperative best corrected visual acuity (BCVA) was compared with postoperative uncorrected visual acuity (UCVA), as well as improved intermediate and near UCVA
