Safety of the ACRIOL 128 Angular-supported Phakic Lens at Three Years of Follow-up

Abstract

Objective: To determine the safety of ACRIOL 128 phakic lens implantation for the correction of high myopia at three-year follow-up.

Methods: Three-year prospective, longitudinal descriptive study of 49 patients (91 eyes) with myopia corrected with ACR-128 phakic lens. Effectiveness and visual quality were determined through the variables uncorrected and best corrected visual acuity, ocular tension, cell density, coefficient of variation, hexagonality and endothelial cell loss, pre- and postoperative; as well as lens-cornea and lens-crystalline distance and complications.

Results: The safety index was >1 and there was no loss of line of sight in the three years; ocular tension with no significant differences between pre- and postoperative (p > 0.05). At 3 and 12 months post-surgery, average endothelial cell loss was 2.08% and 2.86% in the right eye, respectively, and 2.30% and 2.65% in the left eye. At three years it was 3.88 % in OD and 4.07 % in OI. The lens-cornea distance was ≥1.50 mm and lens-crystalline lens ≥0.3 mm, in 100 % of cases.

Conclusions: ACRIOL 128 phakic lens implantation is safe, with no loss of visual acuity and normal ocular strain. It is a procedure well tolerated by the corneal endothelium, with low cell loss, no intraoperative complications and infrequent postoperative complications. The lens position shows safe margins in relation to the anterior segment structures.
