Abstract
CARDENAS DIAZ, Taimi et al. Safety of an ACR-128 phakic lens implant after one year's follow-up. Rev Cubana Invest Bioméd [online]. 2021, vol.40, n.4 Epub Mar 25, 2022. ISSN 1561-3011.
Objective:
Determine the safety 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 lens implants (31 in both eyes and 5 in one eye). Pre- and postoperative determination was made of ocular tension, endothelial cell loss by count, cell variation coefficient and hexagonality, as well as of postoperative complications and lens position with respect to the endothelium and the crystalline lens. Statistical analysis was based on the paired T-test with a significance level of 95%
Results:
Mean age was 28.06 ± 6.14 (25 women and 11 men). An immediate complication was hypotonia: RE: 1 (3.03%), LE: 1 (2.94%). Pupil irregularity was mediate: RE: 1 (3.03%), LE: 1 (2.94%) and late: RE: 1 (3.03%), LE: 2 (5.88%). Total average ocular tension was 14.09 ± 2.51 preoperative and 14.22 ± 2.64 postoperative (p = 0.90). Cell count was 2667.27 ± 228.72 preoperative and 2591.96 ± 301.21 postoperative, with 2.94% total endothelial loss 75.31 ± 237.41 (p = 0.06). Differences were not found in the variation coefficient (p = 0.60) or in hexagonality (p = 0.57). Lens position was 2.09 mm with respect to the endothelium and 1.08 mm with respect to the crystalline lens.
Conclusions:
ACR-128 phakic lens implantation for high myopia correction is a safe procedure with no postoperative complications or modifications in ocular tension or the corneal endothelium after one year's follow-up.
