Topography-Guided Custom Ablation Treatment for Post-Traumatic Corneal Irregularities—Case Reports

Biomedicines
Background: Post-traumatic corneal wounds that require suturing are quite common; they reduce corneal transparency and cause corneal distortion, leading to corneal astigmatism and higher-order aberrations.
