Custom contact lenses and cornea-scleral contact lenses from irregular astigmatism

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.
