摘要
相干光断层扫描(OCT)是20世纪90年代初才发展起来的一种新型无创影像学诊断技术，具有非接触性、非侵入性及高分辨率等特点，在许多眼科疾病的诊断中发挥了其独特的优势。近年来，随着近视眼发病率的增加以及屈光手术技术的发展，有越来越多的人选择了通过角膜屈光手术来矫正视力，达到摘掉眼镜、提升美观的目的。然而，合并有圆锥角膜、青光眼、干眼及部分眼底疾病的患者并不适宜实行角膜屈光手术。因此，术前对这些疾病的筛查检出尤为重要。本文中笔者就OCT对常见而不适宜行角膜屈光手术的疾病在术前筛查和评估方面的运用进行综述，强调此项检查技术在临床上广泛应用的优势，以避免多种术后并发症的发生，提高角膜屈光手术的安全性。
Abstract
Coherent optical tomography (OCT) is a new non-invasive imaging diagnostic technology developed in the early 1990s. It has the characteristics of non-contact, non-invasive, and high-resolution, and has played its unique advantages in the diagnosis of many ophthalmic diseases. In recent years, with the increase of the incidence rate of myopia and the development of refractive surgery technology, more and more people choose corneal refractive surgery to correct their vision, so as to remove glasses and improve their beauty. However, patients with concomitant keratoconus, glaucoma, dry eye, and some fundus diseases are not suitable for corneal refractive surgery. Therefore, it is particularly important to screen and detect these diseases before surgery. The application of OCT in preoperative screening and evaluation of common and unsuitable diseases for corneal refractive surgery were reviewed in this paper, emphasizing the advantages of this examination technique in clinical application, in order to avoid various postoperative complications and improve the safety of corneal refractive surgery.
