Purpose: To evaluate the changes in the angle of the AC and lens vault after IPCL implantation by AS-OCT in myopic patients.
Methods: A prospective observational study involving 30 myopic eyes which were implanted with IPCL with AS-OCT was used for evaluation of the anterior chamber angle parameters as anterior chamber angle (ACA), angle opening distance (AOD) and, trabecular iris space area (TISA) and lens vault at 1,3 and 6 months postoperatively.
Results: There were high significant changes between the preoperative values of ACA, AOD and, TISA and first follow-up after 1 month postoperatively with no significant changes between second and third follow-up after 3 and 6 months postoperatively. Regarding the vault, there were stable vault values with no significant changes after 6 months follow-up.
Conclusion: IPCL is a safe method of correction of myopia with stable AC angle narrowing which was monitored by the safe noncontact tool, AS-OCT.
