Objective: To determine the biometric modifications in myopic patients with ACRIOL 128 phakic lens implantation.
Methods: A cross-sectional study was performed on 31 eyes (17 patients) with high myopia treated with ACRIOL 128 phakic lens implant, between September 2016 and February 2019, which had preoperative biometric measurements with the IOL Master 3.0.2 system and postoperative refractive stability (≤0.5 diopters) after three months of implantation. Postoperative measurements were performed with the IOL Master 3.0.2 in phakic lens mode and with the Scheimpflug Pentacam AXL system for comparison, using the t-test for paired data, with 95% significance.
Results: The average age was 29.82 ± 5.99 years, 82.4% female. The mean preoperative spherical equivalent was -12.00 ± 4.10 diopters. The difference in axial length and anterior chamber depth in millimeters between pre- and postoperative was significant with IOL Master 3.0.2 (0.13 ± 0，33 and -0.08 ± 0.17) and Pentacam AXL (0.12 ± 0.32 and -0.10 ± 0.24), respectively. However, postoperative between the two teams were not significant (p > 0.05) for these variables but significant for keratometries.
Conclusions: Implantation of the ACRIOL 128 phakic lens modifies the measurement of axial length and anterior chamber depth. The IOL Master 3.0.2 and Pentacam AXL provide similar postoperative axial length and anterior chamber depth measurements, but not for keratometries.
