Abstract
Purpose:
To compare angle measurements and vault changes before and after ICL V4c Implantation, in patients with high myopia.
Methods:
Observational, case series. High myopic patients who underwent implantation of ICL4 were analyzed were evaluated using an Anterior Segment OCT. The iridocorneal angle and the ICL vault were measured. OCT measurements were made under different conditions of light to record the changes on vault and angle. Measures were done at day 1, 7, 30, 90 and 180. Paired T-test was used to compare pre and postoperative data.
Results:
10 eyes of 6 patients were enrolled in the study. On postoperative day 1 the angle measurement decreased around 10 degrees in all patients, this being statistically significant (p< 0.05), however over time the change was not significant. On postoperative day 1 the vault was measured around 570 +130 microns (μ) without a significant change on day 7,30,90 and 180.
Conclusions:
The present study demonstrates that with the implantation of ICL V4c for the treatment of high myopia, induces angle measurements changes. The greater the angle measurement the lesser the vault was reported in the majority of patients. There were no changes in vault measurement under the same conditions of light over time.
