IC-8 IOL may improve range of focal distances in cataract patients

Small-aperture technology in an IOL implanted monocularly may effectively improve a broad range of vision in presbyopic patients who require cataract surgery, according to a study.

The prospective, noncomparative multicenter case series investigated the visual performance of 12 cataract surgery patients implanted monocularly with the small-aperture hydrophobic IC-8 IOL (AcuFocus).

Mean monocular uncorrected near, intermediate and distance visual acuity improved significantly from 0.66 ± 0.23, 0.52 ± 0.22 and 0.42 ± 0.18 preoperatively to 0.13 ± 0.15 (P < .0001), 0.09 ± 0.12 (P = .0002) and 0.03 ± 0.10 (P < .0001), respectively, at 12 months.

Additionally, all patients achieved uncorrected distance and intermediate visual acuity of 20/32 or better monocularly and binocularly, while 83% of patients achieved the same uncorrected near visual acuity monocularly and 92% binocularly at month 12.

All eyes had 20/40 or better visual acuity over a defocus range of +0.5 D to –1.5 D.

According to a patient questionnaire, blurry/fluctuating vision was significantly better at the 3-, 6- and 12-month follow-ups, and glare was significantly lower at 12 months postoperatively.

Next, a CE-marked injector designed for the IC-8 IOL will allow implantation through a 3.5- mm incision, rather than 6 mm, to reduce induction of astigmatism, the study said. – by Kristie L. Kahl
