Inclusion criteria
Inclusion criteria: 1. Stable refractive status, defined as a change in spherical equivalent (SE) of =2.8 mm, as measured by ultrasound biomicroscopy (UBM) or anterior segment optical coherence tomography (AS-OCT), to ensure sufficient space for ICL implantation; 3. Sufficient corneal endothelial cell density (ECD) of >=2000 cells/mm² without significant endothelial dysfunction, indicating tolerance for the surgical procedure; 4. Normal ocular anatomy with no significant pathology such as corneal disorders, glaucoma, cataracts, retinal breaks or detachment, or uveitis. The same inclusion criteria were applied to the study subjects in both the retrospective and prospective phases of the research.
Exclusion criteria
Exclusion criteria: 1. Unstable refractive status, defined as a change in spherical equivalent (SE) of >0.50 diopters (D) over the past year or the presence of progressive refractive disorders such as uncontrolled pathological myopia; 2. Insufficient anterior chamber depth (ACD) of 21 mmHg or the presence of glaucoma risk factors such as a family history of glaucoma or narrow anterior chamber angles; 5. Retinal pathology, including retinal degenerative lesions, breaks, a previous history of retinal detachment, or severe vitreous opacity precluding adequate examination. The same exclusion criteria were applied to the study subjects in both the retrospective and prospective phases of the research.
