Purpose

To evaluate refractive outcomes, defocus curve, wavefront analysis, and automated
refraction of a novel monofocal intraocular lens (IOL) with higher-order aspheric coefficients
and controlled curvature change.

Setting

Medical University of South Carolina (MUSC), Storm Eye Institute (SEI), South Carolina,United States

University of Sao Paulo (USP), Sao Paulo, Brazil

Waring Vision Institute, Mount Pleasant, South Carolina,United States

Methods

This prospective observational study included 29 eyes of 29 consecutive patients
with healthy eyes and normal visual potential who had undergone cataract surgery and
implantation of enVista Aspire IOL (EA, Bausch + Lomb, Inc.). Outcome measures included
monocular UDVA, CDVA, DCIVA (at 66 cm), DCNVA (at 40 cm), defocus curve, wavefront
analysis, mean refractive prediction error, automated (ARSE) and manifest refraction
spherical equivalent (MRSE).

Results

The mean UDVA was 20/22, with 93.1% of eyes 20/25 or better. Mean CDVA was
20/20, with all eyes 20/25 or better. Mean DCIVA was 20/34, with 90% of eyes 20/40 or
better. Mean DCNVA was 20/38, with 83% of eyes 20/40 or better. The monocular defocus
curve demonstrated ~1.50 D depth of focus for visual acuity of 0.2 logMAR or better.
Postoperative mean MRSE was close to emmetropia (0.02 ± 0.29 D), and 96.6% of eyes were
within 0.50 D. Automated refraction measured with ray tracing, dynamic sciascopy, and
Hartman-Shack devices were within ± 0.25 D of the subjective refraction. The postoperative
ocular 4 th -order SA measured with Hartmann shack aberrometer was 0.08 µm and 0.15 µm
for 4.5 mm and 6.0 mm pupil, respectively.

Conclusions

The implantation of a new enhanced monofocal IOL demonstrated useful near
and intermediate vision while maintaining excellent distance acuity. Wavefront analysis
revealed minimal post-operative spherical aberration, and the automated refraction was near
emmetropia.
