摘　　要：角膜屈光手术光学区及术后形成的有效光学区大小对视觉质量有着显著影响，研究证实，部分患者出现的夜视力降低、眩光及光晕等视觉不良症状与有效光学区较预计光学区偏小有关。作为激光切削前后提供功能性视觉的角膜表面区域，对有效光学区的精确测量和正确评估极为重要，这不仅可以有效指导手术方案的设计，还可减少或避免手术并发症的产生。The optical zone and effective optical zone have been proven as a significant factor in de- termining the outcomes of corneal refractive surgery. It have been evidenced that the occurrence of night vision symptoms such as glare and haloes were directly related to the effective optical zone reduced compared with the programmed ablation zone. As a area of corneal surface with a high level of optical quality, the accurate measurements and evaluation of the effective optical zone are very important. This not just guide the design of the surgery but evidently avoid the occurrence of surgical complications.
