Prospective study of bilateral mix-and-match implantation of diffractive multifocal intraocular lenses in Koreans.

ABSTRACT: To evaluate monocular and binocular visual outcomes for near, intermediate, and far distance in patients implanted with diffractive multifocal intraocular lenses (IOLs) with different add power contralaterally.This is a prospective contralateral study. Two diffractive multifocal IOLs with different added power were implanted bilaterally in twenty patients. TECNIS® ZKB00 (+?2.75 D) was implanted in a dominant eye, and TECNIS® ZLB00 (+?3.25 D) was implanted in a non-dominant eye. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and manifest refraction (MR) values were measured at 1 month and 3 months postoperatively. At the 3-month follow-up, defocus curve, contrast sensitivity, and reading performance were evaluated. Quality of vision, overall satisfaction, and spectacle independence were evaluated by questionnaire.Postoperative binocular UDVA, visual acuity at 80 cm, 60 cm, 50 cm, 43 cm, 33 cm were -?0.08?±?0.10, 0.12?±?0.14, 0.09?±?0.09, 0.07?±?0.11, 0.14?±?0.09, 0.25?±?0.11 logMAR. The binocular defocus curve showed an extended range of good visual acuity with sharp vision being observed from 0 D to -?2.50 D defocus (logMAR?0.1). Reading performance was significantly improved compared to baseline. All patients were spectacle-free at distance, and 94.74% of the patients did not require glasses for near and intermediate vision.Mix-and-match implantation of diffractive multifocal IOLs with different add power provides an excellent wide range of vision, as well as high levels of visual quality and patient satisfaction.ClinicalTrials.gov , NCT02556944, https://clinicaltrials.gov/show/NCT02556944.
