WebApr 11, 2024 · To explore the efficacy and safety of laser peripheral iridoplasty (LPIp) with different energy levels and locations in the treatment of primary angle closure disease (PACD) assessed by swept-source anterior segment optical coherence tomography (AS-OCT). We enrolled patients with PACD following best-corrected visual acuity (BCVA), … WebWe report the experimental results to continuously tune the coherence length of a semiconductor laser using an optical feedback scheme. The coherence length can be controlled by adjusting the feedback strength when a semiconductor laser operates in a coherence collapse regime.
