The dominant eye was targeted for emmetropia and the non-dominant eye for myopia of − 0.50 to − 0.75D. Binocular uncorrected and corrected distance (UDVA, CDVA), intermediate (UIVA, CIVA), and near (UNVA, DCNVA) visual acuity; reading speeds, defocus curve and contrast sensitivity were studied at 6 months post-operatively.Results: At 6 months post-operatively the mean binocular UDVA, CDVA, UNVA and DCNVA were 0.007± 0.07, − 0.13± 0.06, 0.26± 0.09 and 0.44± 0.10 LogMAR, respectively. Binocular UIVA and DCIVA at 60 cm were 0.22± 0.10 and 0.18± 0.08 LogMAR and at 80 cm was 0.16± 0.11 and 0.15± 0.10 LogMAR, respectively. Mean uncorrected reading speeds evaluated with SRD at 40, 60 and 80 cm were 114.4± 6.9, 126.4± 7.9 and 123.16± 5.8 words per minute. Contrast sensitivity values did not show significant difference for any spatial frequency tested. At 6 months, only 12% (3 patients) reported mild halos. Spectacle independence satisfaction scores were 96%, 100% and 88% for distance, intermediate and near.Conclusion: Implantation of monofocal intraocular lens in one eye and ERV intraocular lens in the contralateral with mini-monovision resulted in good outcomes for far and intermediate, and satisfactory outcomes for near vision, with good tolerance to mini-monovision at the end of 6 months.Keywords: hybrid monovision, extended range of vision IOL, monofocal IOL |
