Abstract Details

Purpose:

To compare monocular and binocular visual performance in cases of bilateral implantation of multifocal intraocular lens (MIOL) or Monofocal Intraocular lens (IOL) implantation , and to compare the subjective perception of near vision.

Setting:

BMI Southend Hospital

Methods:

100 participants presenting to the BMI Southend Hospital requiring bilateral cataract surgery were randomised (1:1 allocation ratio) to receive the Bi-Flex MY MIOL or parent IOL (Bi-Flex 677AB) Patients underwent bilateral phacoemulsifcation and intraocular lens implantation with one of the two IOL types and assessed at 3-6 months and 12-18months after surgery.

Results:

Uncorrected (IOL 0.08 ± 0.11, MIOL 0.10 ± 0.08 LogMAR) and best corrected distance VA (IOL 0.01 ± 0.07, MIOL 0.04 ± 0.06) were comparable (p>0.05) between groups. UNVA and DCNVA were significantly better in the MIOL group (IOL UNVA 0.55 ± 0.20, MIOL UNVA 0.23 ± 0.13; IOL DCNVA 0.54 ± 0.17 and MIOL DCNVA 0.24 ± 0.13). Defocus curves show an increased range of focus with MIOLs (MIOL, 4.16D ± 1.09 and IOL 2.30D ± 1.04). Subjective perception of near vision was better in the MIOL group (IOL NAVQ 53.76 ± 23.89 and MIOL 20.12 ± 22.25).

Conclusions:

Unaided near visual acuity was significantly better with the MIOL, and greater spectacle independence was found in this group. Halos and glare were reported in the MIOL group, but the prevalence did not show an adverse effect on overall satisfaction.
