Inclusion criteria
Inclusion criteria: 1. Age at surgery ranged from 18 to 45 years old. 2. Preoperative refractive error: myopia from -0.5 D to -18.0 D, with or without astigmatism = 6.0 D. 3. Bilateral eyes implanted with either EVO+ ICL (V5) or EVO+ Toric ICL (V5).
Exclusion criteria
Exclusion criteria: 1. Patients with low/abnormal corneal endothelial cell density, Fuchs endothelial corneal dystrophy, or other corneal diseases. 2. Ocular hypertension in either eye. 3. Presence of any type of cataract in the operative eye, or non-traumatic cataract in the fellow eye. 4. Primary open-angle glaucoma or narrow-angle glaucoma. 5. Narrow anterior chamber angle (e.g., grade less than ? confirmed by gonioscopy). 6. Pregnancy or lactation period. 7. History or presence of any ocular disease that is expected to result in a postoperative visual acuity worse than 0.477 logMAR (20/60 Snellen) or inability to achieve better postoperative visual sensitivity. 8. Anterior chamber depth (ACD) of the eyes scheduled for lens implantation, measured from the corneal endothelium to the anterior lens capsule, less than 2.80 mm.
