The study object is moderate and high myopia patients, underwent ICL implantation. OCTA was used to image the superficial and deep retinal vascular plexuses before ICL implantation surgery and at 3 months follow-up. OCTA images were corrected for magnification, skeletonized, separated the large vessels and partitioned. Retinal microvascular density was measured by using fractal dimension analysis. The aim of this study was to uncover potential retinal vascular network alterations induced by ICL implantation surgery.
To observe the retinal microvascular alteration during 3 months follow-up after Implantable Collamer Lens (ICL) operation in moderate and high myopia patients using quantitative optical coherence tomography angiography (OCTA) analysis.
