| Titel | Iol Calculations after Previous Refractive Surgery | 
| Doel | To evaluate a new technique in our diagnostic tools. | 
| Methodes | The theory of aberrometry will be explained. | 
| Resultaten | In cases of visual complaints, aberrometry goes beyond refraction and standard topographical maps: it helps us to understand why some patients remain unhappy after refractive surgery, despite of a perfect procedure and a perfect anatomical result. Some examples will be presented. | 
| Conclusie | Aberrometry is an invaluable tool for the clinician and the surgeon; however, it is time consuming, requires a perfectly trained technician, and is more difficult to interprete than corneal topography. |
