摘要

目的探讨角膜中央厚度(CCT)、角膜曲率(CC)和眼压(IOP)作为角膜生物力学和屈光手术的决定性因素之间的关系。方法对在眼科准分子激光手术门诊就诊的48只眼进行调查。测量所有受试者的屈光不正、IOP、CCT和CC。3个月后，重复所有检查。结果线性回归显示术前和术后CCT、CC和IOP值呈正相关。prk前IOP与CCT有显著相关性(P = 0.033)， prk后IOP与CCT无显著相关性。prk前后CCT与CC均有显著相关(P < 0.05)。结论术前眼压与CCT有显著相关，术后眼压与CCT有显著差异。PRK前后CCT和CC之间的相关性几乎相同;然而，在基于CCT校正的PRK之后，IOP测量值应该更精确地计算或估计。

Relationship between corneal thickness, corneal curvature, and intraocular pressure before and after laser treatment for simple myopia.

PURPOSE To determine the relationship of central corneal thickness (CCT), curvature (CC), and intraocular pressure (IOP) as determinative factors for corneal biomechanics and in refractive surgery. METHODS The study investigated 48 eyes from subjects who visited the Excimer Laser Surgery Clinic at the Department of Ophthalmology. The refractive error, IOP, CCT, and CC were measured in all participants. After 3 months, all examinations were repeated. RESULTS Linear regression demonstrated a significant positive relationship between pre- and postoperative CCT, CC, and IOP values. The IOP showed a significant correlation with CCT (P = 0.033) for pre-PRK, but no significant relationship was seen post-PRK. The CCT also correlated significantly with CC both pre- and post-PRK (P < 0.05). CONCLUSION The IOP was significantly correlated with CCT before PRK, but its behavior differed after surgery. Nearly the same correlation was seen between CCT and CC before and after the PRK; nevertheless, IOP measurements should be calculated or estimated more precisely after PRK based on CCT corrections.

期刊介绍： Eye science was founded in 1985. It is a national medical journal supervised by the Ministry of Education of the People's Republic of China, sponsored by Sun Yat-sen University, and hosted by Sun Yat-sen University Zhongshan Eye Center (in October 2020, it was changed from a quarterly to a monthly, with the publication number: ISSN: 1000-4432; CN: 44-1119/R). It is edited by Ge Jian, former dean of Sun Yat-sen University Zhongshan Eye Center, Liu Yizhi, director and dean of Sun Yat-sen University Zhongshan Eye Center, and Lin Haotian, deputy director of Sun Yat-sen University Zhongshan Eye Center, as executive editor. It mainly reports on new developments and trends in the field of ophthalmology at home and abroad, focusing on basic research in ophthalmology, clinical experience, and theoretical knowledge and technical operations related to epidemiology. It has been included in important databases at home and abroad, such as Chemical Abstract (CA), China Journal Full-text Database (CNKI), China Core Journals (Selection) Database (Wanfang), and Chinese Science and Technology Journal Database (VIP).
