Objective:

Describe the visual results of correction of high myopia with ACR-128 phakic lens implantation.

Methods:

An observational descriptive longitudinal prospective study was conducted of 60 eyes of 32 patients with myopia corrected with the ACR-128 phakic lens. Determination was made of the expected and observed spherical component, the keratometric cylinder, uncorrected and best corrected visual acuity in the pre- and postoperative periods, and induced astigmatism. Statistical analysis was based on the paired T-test with a significance level of 95 %.

Results:

Mean age was 27.41 ± 5.91 years, preoperative spherical equivalent was -11.54 ± 3.20 diopters, and 68.75 % of the patients were female. Spherical component in diopters expected (-0.53 ± 0.37) and observed (-0.42 ± 0.47) without differences (p= 0.0742). Between ± 1.00 diopters 91.67 % and between ± 0.50 diopter 70 %. No eye was above +0.50D. Keratometric cylinder in diopters, preoperative (1.44 ± 0.76) and postoperative (1.49 ± 0.84) without induced astigmatism (p=0.6377). In 100 % visual acuity without correction ≤ 0.1 preoperative and ≥ 0.3 postoperative. After surgery 10 % reached 1.0 and 71.6% ≥ 0.5. Only 28.33% had the unit corrected in the preoperative period and 70 % in the postoperative period (98.33 % ≥ 0.7).

Conclusions:

ACR-128 phakic lens implantation provides patients with favorable refractive correction and predictability. This is achieved by reducing the spherical component to desired values, not inducing astigmatism and improving visual acuity, all of which leads to an adequate visual result.
