1️⃣ Stage of Keratoconus
Earlier stages generally respond more favorably, with greater improvement in visual acuity. In advanced stages, functional gain may be more limited.
2️⃣ Morphological Type of Keratoconus
Not all keratoconus patterns behave the same. Topography and detailed examination guide us in predicting the likely response.
3️⃣ Age of the Patient
Corneal biomechanics differ with age. Younger corneas tend to be more elastic and adaptable, while older corneas show less remodeling capacity.
4️⃣ History of Cross-Linking
Prior cross-linking often results in a stiffer cornea, which can reduce the degree of postoperative corneal reshaping achieved with CAIRS.
5️⃣ Presence of Corneal Opacities or Scarring
In advanced keratoconus, and particularly in eyes that have undergone cross-linking, corneal clarity may be reduced by central scarring or haze. This subgroup typically demonstrates less visual improvement.
🌟 While outcomes vary, the overarching principle is that CAIRS aims to regularize corneal shape and improve functional vision. Even in advanced cases, patients may benefit, though expectations should be realistic. In contrast, earlier intervention often leads to more substantial visual gains and improved quality of life.
