Postoperative manifest refraction was also improved by surgery, showing minimal but significant regression after 1 year. Final BCVA loss was seen in 10 eyes of 7 patients; in 7 cases, there were obvious reasons such as the progression of cataracts in 3 eyes, epithelial disintegrity due to dry eye in 2 eyes, irregular astigmatism due to flap striae in 1 eye, and age-related macular dystrophy in 1 eye.

手术后的显然验光视力也有提高，在1年后表现为极微量却显著的回退。7例患者的10只眼发生了最佳矫正视力的下降，但均有明显原因，如3只眼发生了白内障，2只眼角膜上皮不完整，1只眼由于角膜瓣皱褶导致不规则散光，1只眼为年龄相关性黄斑萎缩。

The mechanism in which trehalose is produced from dextrin or starch hydrolyzate by endocellular enzymes of bacterium D-97 can be elucidated by high performance liquid chromatography with differential refraction detection basically, including the effect of the different carbon sources on the endocellular trehalose-producing enzymes in bacterium D-97 and the possibility or ability of the endocellular enzymes to produce trehalose using maltooligosaccharides of different chain lengths.

通过高效液相色谱/示差折光检测系统分析可获得细菌D-97利用糊精或淀粉水解物合成海藻糖的基本生物学信息，包括微生物培养碳源对细菌D-97胞内海藻糖合成酶系的影响以及该酶系利用不同种类或不同分子链长度的麦芽寡糖合成海藻糖的能力及作用过程。
