Scheimpflug topographical changes after Femtosecond LASIK for mixed astigmatism - theoretical aspects and case study.

Objective

To evaluate the corneal topographical changes after Femtosecond-LASIK surgery in eyes with mixed astigmatism.

Methods

We present the analysis of the corneal Scheimpflug topographies of a patient treated with Femtosecond-LASIK technique for bilateral mixed astigmatism.

Results

Three-dimensional reconstruction maps and differential anterior curvature maps were used to demonstrate the ablation profile and its stability in time.

Conclusions

Visual and refractive results were very good after surgery, being topographically confirmed by the corneal reshaping which was performed as planned, the achieved ablation being stable during the one-year follow-up period.
