Wet and Dry Corneal Topography? – A New Contraindication for the LASIK Procedure in Refractive Surgery

The corneal topographer is an indispensable tool and plays a critical role in the practice of refractive surgery. In corneal refractive surgery, corneal topography is used preoperatively to detect irregular astigmatism, ectatic corneal disorders, or other abnormalities, and to monitor topographic stability following discontinuation of contact lens wear. Postoperatively, it is used to monitor and assess the surgical outcomes, detect the causes of visual symptoms, and refine and develop surgical techniques for retreatment. 1. Examining the corneal topography carefully is a necessity for a successful corneal ablation procedure like in PRK, LASEK, EpiLASIK and LASIK. 2. However it must be understood that when performing a corneal topography, the anterior surface of the cornea is NOT measured but the anterior surface of the tear film. 3. In this study the topography of the tear film was studied in detail and the topography of this film is called the TOPOFILM.
