          Abstract

          Purpose

          To compare long-term clinical outcomes between patients with bilateral implantation of +3.0 diopter (D) multifocal intraocular lenses (IOLs) and mix and match implantation of +2.5 D and +3.0 D multifocal IOLs.

          Material and Methods

          This retrospective observer-masked cohort study comprised 66 eyes of 33 patients with two different strategies of binocular multifocal IOLs implantation: bilateral +3.0 D (17 patients) (bilateral group) and mix and match +2.5 D and +3.0 D (16 patients) (blended group). Patients were recruited 1 year (±3 months) after second-eye surgery. The primary effectiveness endpoint was binocular uncorrected intermediate visual acuity (UCIVA) at 70 cm. The secondary assessments included binocular visual quality tests and quality-of-vision questionnaire.

          Results

          The blended group showed clinically better UCIVA (0.10 ± 0.07 logMAR) at 70 cm than the bilateral group (0.26 ± 0.09 logMAR) with a difference of 0.16 ± 0.08 logMAR ( P < 0.001). Similar binocular visual acuities were achieved between the two groups at the near and far distance. The binocular defocus curves showed better performance in the blended group from 50 cm to 1 m. The mean binocular contrast sensitivities under the photopic conditions with or without glare and mesopic condition without glare were clinically better in the blended group. Both the groups reported low rate of visual phenomena, high rate of spectacle independence, and satisfaction.

          Conclusions

          Comparing with bilateral implantation of +3.0 D multifocal IOLs during the cataract surgery, mix and match implantation of +2.5 D and +3.0 D multifocal IOLs provides a wider depth of binocular focus, especially for intermediate distances, and better binocular visual quality.

          Multifocal intraocular lenses: An overview.

          Multifocal intraocular lenses are increasingly used in the management of pseudophakic presbyopia. After multifocal intraocular lens implantation, most patients do not need spectacles or contact lenses and are pleased with the result. Complications, however, may affect the patient's quality of life and level of satisfaction. Common problems with multifocal lenses are blurred vision and photic phenomena associated with residual ametropia, posterior capsule opacification, large pupil size, wavefront anomalies, dry eye, and lens decentration. The main reasons for these are failure to neuroadapt, lens dislocation, residual refractive error, and lens opacification. To avoid patient dissatisfaction after multifocal intraocular lens implantation, it is important to consider preoperatively the patient's lifestyle; perform an exhaustive examination including biometry, topography, and pupil reactivity; and explain the visual expectations and possible postoperative complications.
