Abstract Details

Purpose:

To evaluate the post-operative far, intermediate, near visual acuity and contrast sensitivity of the eye implanted with a small-aperture extended depth of focus IOL

Setting:

San Bassiano Hospital, Bassano del Grappa (VI), Italy

Methods:

We implanted 7 patients affected by bilateral cataract. Any ocular pathologies, astigmatism more than 1,75 D and potential visual acuity less than 20/25 were exclusion criteria. All eyes were implanted in dominant eye with monofocal Tecnis IOL achieving emmetropia. In non dominant eye IC-8 IOL (Acufocus, Inc.) was implanted achieving -0,75 target refraction. Post operative UDVA, UIVA, UNVA were evaluated by ETDRS test after 1st week, 1st month, 3rd months, 6th months. Defocus curve, macular OCT and contrast sensitivity by Optec ® 6500P stereo optical company, Inc. and patients satisfaction questionnaire were evaluated at 3rd months.

Results:

Mean age for this cohort was 72.6 years +/- 6.02. The mean achieved binocular UDVA, UIVA and UNVA was -0.07 +/- 0.10 (6/4.8), 0.00 +/- 0.04 (6/6) and 0.1 +/- 0.10 (6/7.5) respectively at 6 months. Binocular defocus curve showed that monocular small aperture IC-8 IOL implantation extends depth of focus providing 3.0 diopters of functional vision. Mesopic binocular contrast sensitivity with no glare was 1.674 logCS at 1.5 cpd, 1.696 logCS at 3 cpd, 1.388 logCS at 6 cpd and 0.748 logCS at 12 cpd.

Conclusions:

All patients achieved binocular uncorrected visual acuity of 20/25 Snellen equivalent or better for far, intermediate and near vision with excellent visual acuity across all focal distances. Mesopic binocular contrast sensitivity with no glare was within normal range. No patients complained of blurry vision, fluctuating vision, glare, halo, double vision and ghosting image. All reported “satisfied” or “very satisfied” on overall vision.
