Abstract

CARDENAS DIAZ, Taimi et al. Effectiveness of an ACR-128 phakic lens implant after one year's follow-up. Rev Cubana Invest Bioméd [online]. 2020, vol.39, n.4, e754.  Epub Jan 01, 2021. ISSN 0864-0300.

Introduction:

Correction of moderate-severe ametropia with phakic lenses makes it possible to preserve accommodation and provides better optical quality, reversibility of the procedure and the option of correcting residual refractive defects by minimally invasive corneal surgery.

Objective:

Determine the effectiveness of ACR-128 phakic lenses for high myopia correction one year after implantation.

Method:

A cross-sectional study was conducted of 67 eyes of 36 patients with myopia corrected with ACR-128 phakic lenses. Determination was made of the biometric and refractive characteristics of each eye, the relationship between the expected and the observed spherical component, the distribution of the expected and the observed spherical component per eye, the relationship between the pre- and postoperative keratometric cylinder, and the relationship between pre- and postoperative uncorrected and best corrected visual acuity.

Results:

Mean age was 28.06 ± 6.14 (25 women, 11 men). Average preoperative spherical equivalent was -10.77 ± 4.23 diopters RE and -10.77 ± 3.72 diopters LE. Spherical component in diopters: expected (-0.56 ± 0.38) and observed (-0.43 ± 0.69), without statistically significant differences (p= 0.14). Keratometric cylinder in diopters: preoperative (1.41 ± 0.74) and postoperative (1.24 ± 0.88), without induced astigmatism (p = 0.12). In 100 % visual acuity without correction was ≤ 0.1 preoperative and ≥ 0.5 postoperative.

Conclusions:

One year after ACR-128 phakic lens implantation for high myopia correction, the treatment remains effective, reducing the spherical component and maintaining it at the desired level, not inducing astigmatism and preserving best visual acuity.
