Abstract：
PURPOSE:To describe the rationale behind elliptical and other transition designs used with the excimer laser. SETTING:Casey Eye Institute, Oregon Health Sciences University, Portland, Oregon, USA. METHODS:Ablation zone designs were analyzed for the number of transition points for myopia and hyperopia. The advantages and disadvantages of elliptical transition zones are demonstrated graphically, with an emphasis on smooth ablation zone design to maximize the optics and biologic tolerance by the eye. RESULTS:The use of an individualized elliptical transition maximizes a circular effective optical zone and can enhance the smoothness of the transition zone while minimizing excessive tissue removal. CONCLUSION:Elliptical transition zones may improve the optics and biologic tolerance of excimer laser treatments.
