Objective: To show the improvement of visual acuity in five clinical cases of irregular astigmatism, achieved with contact lenses of different materials and geometries.  Case reports: Five case reports are exposed and their adaptations for the use of this type of lenses are evaluated. After inserting corneo-scleral lenses or soft contact lenses, each adaptation is evaluated.  Results: All patients have improved meaningfully their visual acuity without affecting their corneal integrity and improving their quality of life.  Conclusion: Advances in the design and materials of contact lenses have helped eye-care professionals to solve visual problems that would have been difficult to solve years ago.  Keywords: irregular astigmatism, keratoconus, keratoplasty, custom contact lenses, cornea-scleral contact lenses
