PURPOSE
To assess a decision tree analysis system to further optimize refractive surgery outcomes.
METHODS
A 5-step decision tree, the Decision Assistant Wizard, based on previous experience with the SCHWIND AMARIS laser, was applied for selecting a customized refractive surgery treatment mode (aspheric aberration neutral, corneal wavefront-guided, or ocular wavefront-guided) to eliminate or reduce total aberration.
RESULTS
Using the Decision Assistant Wizard, 6467 LASIK treatments were performed over a 30-month period; 5262 and 112 for myopic and hyperopic astigmatism, respectively, using aspheric aberration neutral (AF) profiles, 560 using corneal wavefront-guided profiles, and 533 using ocular wavefront-guided profiles. Twenty-two (0.3%) retreatments were performed overall; 18 (0.3%) and 0 (0%) after myopic and hyperopic astigmatism, respectively, using AF, 3 (0.5%) after corneal wavefront-guided profiles, and 1 (0.2%) after ocular wavefront-guided profiles.
CONCLUSIONS
Decision Assistant Wizards may further optimize refractive surgical outcomes by providing the most appropriate ablation pattern based on an eye's anamnesis, diagnosis, and visual demands. The general principles may be applied to other laser systems; however, specifics will depend on manufacturers' specifications.
目的
评估决策树分析系统，以进一步优化屈光手术效果。
方法
采用五步决策树分析系统——决策助手向导（Decision Assistant Wizard），该系统基于先前对 SCHWIND AMARIS 激光的经验，用于选择定制的屈光手术治疗模式（非球差中和、角膜波前引导或眼波前引导），以消除或减少总像差。
结果
在 30 个月的时间里，使用决策助手向导共进行了 6467 例 LASIK 治疗；其中 5262 例为近视散光，112 例为远视散光，分别采用非球差中和（AF）模式、560 例采用角膜波前引导模式和 533 例采用眼波前引导模式。总共进行了 22 例（0.3%）的翻修手术；其中，18 例（0.3%）和 0 例（0%）分别为近视散光和远视散光患者采用 AF 模式，3 例（0.5%）为角膜波前引导模式，1 例（0.2%）为眼波前引导模式。
结论
决策助手向导可以根据患者的病史、诊断和视觉需求，提供最合适的消融模式，从而进一步优化屈光手术效果。这些一般原则可应用于其他激光系统；但是，具体情况将取决于制造商的规格。
