Objective To analyze the distribution of the higher order aberrations myopic eyes and observe the influences of the degree of myopic and age in higher aberrations.
近视的回退量与年龄及术后角膜基质床厚度成负相关性，与术前的近视度数成正相关性。
The degree of myopia regression had negative relations to the patient's age and postoperative thickness of cornea stroma, but had positive relations to the degree of preoperative myopia.
结论：角膜塑形镜治疗近视具有特有的降低近视度数速度快、效果显著、安全、可逆的优势，但矫正近视度有一定适用范围。
CONCLUSION: Orthokeratology has the quick, effective, safe, and reversible advantages for myopia, whereas it has certain applicability for correction of myopia.
与角膜厚度、眼压无明显的相关性。结论眼轴长度、角膜屈光力、晶状体厚度、前房深度和年龄对近视度数(等值球镜度数)均有一定的影响。
Conclusion the length of axis, corneal refractive power, lens thickness, anterior chamber depth and age have certain effect on the spherical equivalent refraction.
屈光性角膜切除术(PRK)：当你有低于中等度数的近视或者远视，或者近视加散光，有时会选择prk。
Photorefractive keratectomy (PRK). PRK is sometimes used if you have a low to moderate degree of nearsightedness or farsightedness, or if you have nearsightedness with astigmatism.
怎样可以不让近视的度数加深？
对于假性近视、或预防近视眼度数的加深有好处。
For pseudo myopia, or preventing myopia degree deepened to have the advantage.
图解法分析得出，两次屈光检查度数相差-0．25D左右时即被认为近视已停止进展。
The diagram reveded that the myopia stopped advancing when the difference in examining diopter was about 0. 25D.
如果近视？你眼镜的度数是多少？
If you are near-sighted, what power of your glasses (spectacles, lenses)?
屈光参差者的高度数眼表现出更多的主觉调节滞后量，近视的发生与该眼有更大的调节调节滞后相关。
The high myope eye had the higher accommodation lag. The myope may need higher accommodation stimulus to reach the demand.
然而，如今的年轻人很容易就可避免近视或降低度数，杜克大学的特里-扬说：“人们得到外面走走，看看地平线。
However, , today's youngsters can take some simple steps to try to discourage shortsightedness. Terri Young of Duke University said: "People need to go outside and look at the horizon."
结论：影响近视眼患者角膜中央厚度的主要因素是：配戴角膜接触镜史、屈光度数和眼压。
CONCLUSION: The CCT in patients of myopia was correlated with history of wearing soft contact lens, refraction and IOP.
结论：对于高度近视患者的人工晶体度数的计算，不仅要精确术前的生物测量、选择合适的计算公式，还需要根据患者不同的视力需求进行人工晶体度数的设计。
SRK-T formula had the best predictability. Conclusion: Accurate measurement data, suitable formula selection and the patient's need of visual function are important in myopia IOL calculation.
