Purpose: To evaluate the changes in the angle of the AC and lens vault after IPCL implantation by AS-OCT in myopic patients. Methods: This was a prospective observational study involving 30 myopic eyes implanted with IPCL. AS-OCT was used to evaluate lens vault and AC angle parameters including anterior chamber angle, angle opening distance and trabecular-iris space area (TISA) at 1, 3 and 6 months postoperatively. Results: All 3 AC angle parameters were significantly reduced at the 1st postoperative month compared to preoperative values, but remained stable thereafter with no significant change at the 3rd or 6th postoperative months. The lens vault showed no significant change over the entire follow-up period. Conclusion: IPCL implantation is a safe method for correction of myopia with stable AC angle narrowing over the course of 6 months postoperatively as monitored using AS-OCT. [ABSTRACT FROM AUTHOR]

Purpose: To introduce the use of corneal epithelial mapping by anterior segment optical coherence tomography (AS-OCT) as an ancillary testing for the identification of areas of loose epithelial adherence in recurrent corneal erosion syndrome (RCES), and the subsequent treatment of the latter with anterior stromal puncture (ASP). Methods: Five patients were presented with RCES following traumatic corneal abrasions. Following resolution of acute episodes, AS-OCT epithelial mapping was performed revealing in all patients an area of increased epithelial thickness (hot spot) corresponding to the site of loose attachment of the epithelium to the epithelial basement membrane. ASP to the area of epithelial thickening, as delineated by the epithelial map, was performed. Results: To date, none of the patients has shown any signs of disease recurrence over a period ranging from 6 to 20 months following the application of epithelial map-guided ASP. Conclusions: AS-OCT epithelial mapping can reveal the exact area of loose epithelial adherence in RCES. Hence, epithelial mapping can delineate the target area for treatment with ASP and may decrease the high failure rates of ASP. [ABSTRACT FROM AUTHOR]
