The prevalence of keratoconus is now between 1/600 and 1/1000 in general, and is even higher in certain regions of the world. Early detection of keratoconus is crucial, given that effective treatments are now available to counter its progression and maintain optimal vision and quality of life. The methods for detecting conus are presented, highlighting those that may be useful in the absence of topography, which remains the standard. With the help of case reports, this conference describes the lifelong journey of the keratoconus, from detection at a young age, through to post-treatment needs – and the selection of appropriate visual correction methods. The speaker then discusses the adaptations required as visual needs change, particularly with presbyopia and cataracts. The choice of an appropriate implant is then crucial for the future. Finally, the speaker discusses how we can support elderly patients for whom traditional methods of correction are no longer an option. In particular, the importance of refraction in keratoconus patients is highlighted. With the help of case reports, participants will understand that keratoconus is a disease of a lifetime.
