Purpose:
To compare the visual acuity and satisfaction outcomes of 2 different concepts of extended depth-of-focus intraocular lenses (EDOF IOLs).
Setting:
University Eye Hospital Bochum, Germany.
Design:
Prospective randomized comparative clinical trial.
Methods:
Patients undergoing cataract surgery with the implantation of 2 different concept EDOF IOLs. In the first group (IC-8 Group), a monofocal 1-piece Tecnis Z B00 IOL (Johnson & Johnson Vision Care, Inc.) was implanted in the dominant eye, and an IC-8 IOL (AcuFocus) was implanted in the nondominant eye. In the second group (Symfony Group), a Tecnis Symfony IOL (Johnson & Johnson Vision Care, Inc.) was implanted in both eyes. The target refraction of the dominant eye was emmetropia and slight myopia (mini-monovision, −0.75 diopters) in the nondominant eye. Visual and refractive outcomes and patient satisfaction rates were evaluated 3 months postoperatively.
Results:
This study comprised 76 eyes of 38 patients. No intraoperative or postoperative complications occurred in either group. Target refraction was reached in both groups without statistically significant differences. The uncorrected distance visual acuity (UDVA, photopic and mesopic light conditions) was excellent in both groups with statistically significantly better results in the IC-8 goup (logarithm of the minimum angle of resolution; IC-8 Group (0.1 ± 0.07 logarithm of the minimum angle of resolution [logMAR]; Symfony Group 0.07 ± 0.1 logMAR, P value .02 [photopic]; IC-8 group 0.12 ± 0.09 logMAR, Symfony group 0.22 ± 0.1 logMAR, P value < .01 [mesopic]). Binocular uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) were also good in both groups without statistically significant differences (UIVA: IC-8 Group, 0.01 ± 0.07 logMAR, Symfony Group 0.01 ± 0.08 logMAR, P value .35; UNVA: IC-8 Group 0.14 ± 0.11, Symfony Group 0.09 ± 0.08, P value .14). Subjective satisfaction was high in both groups.
Conclusions:
Both EDOF IOLs provided a very good UDVA with superior results in the IC-8 Group, and a good UIVA and UNVA under photopic light conditions. Subjective patient satisfaction was higher in the IC-8 Group.
PURPOSE:
To compare the clinical outcomes of binocular cataract surgery with and without pinhole corneal inlay implantation.
METHODS:
In the inlay-cataract group, a small aperture corneal inlay was implanted in addition to cataract surgery in the non-dominant eye and routine cataract surgery was performed in the dominant eye. In the control group, conventional cataract surgery was performed in both eyes in separate consecutive surgeries 2 weeks apart. The target refraction was emmetropia. Visual acuity, refraction, contrast sensitivity, and visual field were analyzed 1, 4, and 12 weeks after surgery.
RESULTS:
Sixteen patients with advanced cataracts underwent cataract surgery on both eyes in separate surgeries. There was no statistically significant difference regarding mean age, Lens Opacities Classification System grading, and refractive outcome. The difference in uncorrected distance visual acuity between the control group and inlay-cataract group was not statistically significant after 12 weeks (
P
= .59). Mean uncorrected intermediate visual acuity was significantly better in the inlay-cataract group (
P
= .03). Near visual acuity was better in the inlay-cataract group, but it was not statistically significant (
P
= .07). There was no statistically significant difference between groups under binocular photopic and mesopic conditions with and without glare. The results of the visual field examination showed no statistically significant difference between both eyes.
CONCLUSIONS:
The findings demonstrate that implantation of monofocal IOLs in combination with a small aperture corneal inlay in the non-dominant eye helps to increase intermediate and near visual acuity. The implantation of small aperture corneal inlays seems to be an interesting alternative for pseudophakic patients who desire spectacle independence.
