The aim of this study was to report cases that had used mini-scleral lenses to manage keratoconus and post-laser-assisted in situ keratomileusis (LASIK) ametropia and keratectasia. The first patient was a 32-year-old man who came to our clinic seeking to correct his vision. Following the LASIK procedure, his refraction gradually shifted toward hyperopia. He initially tried wearing spectacles and traditional rigid gas permeable (RGP) lenses, neither of which showed improvement. The second patient was a 28-year-old woman who complained of gradually worsening vision in her right eye after having received LASIK. She was diagnosed with corneal ectasia after a complete ophthalmic examination. She tried wearing spectacles and soft contact lenses, but neither showed any improvement. The third patient was a 29-year-old man with a long history of poor vision. He was first diagnosed with keratoconus in our clinic. He initially tried wearing a Rose K contact lens for the keratoconus in his right eye, but the lens rode low. After the initial treatment attempts, all three patients tried mini-scleral lenses, and their visual acuity improved to between 20/50 and 20/20. They were all able to wear the lenses for more than 10 hours a day without feeling any discomfort. In conclusion, mini-scleral lenses provide better comfort and vision in patients with keratoconus and post-LASIK keratectasia and ametropia.
