Abstract

Purpose: Analysis of changes in corneal curvature and astigmatism after phacoemulsification for senile cataracts.

Methods: Retrospective collection of clinical data from patients who underwent uncomplicated phacoemulsification at the First Affiliated Hospital of Soochow University. The changes in total corneal curvature, anterior surface curvature, posterior surface curvature, and astigmatism were measured by the Sirius system. The axial length was measured by Lenstar 900.

Results: The total corneal curvature and anterior surface curvature at 3 months were all larger than those before phacoemulsification, and the difference was statistically significant (p < 0.05). Compared with preoperative results, there was no significant change in corneal posterior surface curvature and astigmatism 3 months after surgery (p > 0.05). Changes in corneal curvature and astigmatism were not significantly correlated with age at 3 months after surgery (p > 0.05). Postoperative astigmatism was increased with the growth of axial length, while corneal curvature was decreased (p < 0.05).

Conclusion: Phacoemulsification can lead to increased postoperative corneal curvature in elderly cataract patients, and with the growth of the axial length, the corneal astigmatism was increased.

超声乳化术后老年性白内障患者角膜曲率和散光的变化。

目的：分析老年性白内障超声乳化术后角膜曲率和散光的变化：回顾性收集在苏州大学附属第一医院接受无并发症超声乳化术的患者的临床数据。总角膜曲率、前表面曲率、后表面曲率和散光的变化由 Sirius 系统测量。结果：结果：3 个月时的总角膜曲率和前表面曲率均大于超声乳化前，差异有统计学意义（P P > 0.05）。术后 3 个月，角膜曲率和散光的变化与年龄无明显相关性（P > 0.05）。术后散光随着轴长的增长而增加，而角膜曲率则下降（p 结论：角膜曲率和散光的变化与年龄无明显关系（p > 0.05）：超声乳化术可导致老年白内障患者术后角膜曲率增加，并且随着轴长的增长，角膜散光也会增加。

期刊介绍： Frontiers in Medicine publishes rigorously peer-reviewed research linking basic research to clinical practice and patient care, as well as translating scientific advances into new therapies and diagnostic tools. Led by an outstanding Editorial Board of international experts, this multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide. In addition to papers that provide a link between basic research and clinical practice, a particular emphasis is given to studies that are directly relevant to patient care. In this spirit, the journal publishes the latest research results and medical knowledge that facilitate the translation of scientific advances into new therapies or diagnostic tools. The full listing of the Specialty Sections represented by Frontiers in Medicine is as listed below. As well as the established medical disciplines, Frontiers in Medicine is launching new sections that together will facilitate - the use of patient-reported outcomes under real world conditions - the exploitation of big data and the use of novel information and communication tools in the assessment of new medicines - the scientific bases for guidelines and decisions from regulatory authorities - access to medicinal products and medical devices worldwide - addressing the grand health challenges around the world
