Abstract Details

Purpose:

To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a “mix & match” approach.

Setting:

Dokuz Eylul University, School of Medicine, Dep of Ophthalmology, Izmir – Turkey

Methods:

Prospective. Twenty patients (40 eyes) were involved in this prospective, nonrandomized, casecontrol study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients’ dominant eyes and diffractive multifocal IOLs (Tecnis ZMA00) were implanted in their nondominant eyes. Patients were followed for 6 months. Monoocular and binocular uncorrected distance, intermediate and near vision acuity (logMAR), contrast sensitivity levels were measured 1, 3 and 6 months later after cataract surgery. Defocus curves, reading speeds, patient satisfaction, spectacle dependence, halo and glare symptoms were also evaluated at 6 month after the surgery. Postoperative quality of life was assessed with the Turkish version of NEI VFQ-25 (National Eye Institute Visual Function Questionnaire-25).

Results:

The study group consists of 8 females and 12 males, with mean age 69.45 ± 10.76 (31-86) years. At 6 months after the surgery the mean spherical equivalent was -0.04 ± 0.12 D in ReZoom implanted eyes and -0.11 ± 0.2 D in Tecnis implanted eyes. The uncorrected distance and intermediate visual acuity levels were significantly better in ReZoom implanted eyes at 6 months after the surgery (p=0.026 and p=0.037,respectively). There was no statistically significant difference in the uncorrected near viasual acuity (p>0.05). At the final visit, the mean binocular uncorrected distance visual acuity was -0.05±0.1 logMAR, the mean binocular uncorrected intemediate visual acuity was 0.1±0.2 logMAR and the mean binocular uncorrected near visual acuity was 0.1±0.1 logMAR. There was no statistically significant difference in contrast sensitivity, reading speed, halos, or glare between the groups (p<0.05). Contrast sensitivity measurements under photopic and mesopic conditions were within normal limits during all the follow-up periods. The mean patient satisfaction was 95% and all patients were totally spectacle independent. A low degree of glare/halo was detected in 40% of the subjects. There was no postoperative complication.

Conclusions:

Mixing and matching multifocal IOLs in selected cataract patients provide an excellent visual outcome, a high level of patient satisfaction and spectacle independency.
