影响角膜屈光手术矫正散光效果的因素
|
Abstract:
近年来，角膜屈光手术在近视矫正方面取得了良好的效果，但部分患者出现术后视觉质量下降。散光是屈光不正的一种，其矫正效果与术后视觉质量密切相关。深入研究影响散光矫正效果的因素，不仅有助于优化手术流程，减少术后并发症，还有助于获得更优的术后效果。本文简要概述了目前角膜屈光手术矫正散光的主要术式，同时分析了影响散光矫正效果的多个因素，包括术前散光的大小、来源及类型、术中激光能量的设置、术中眼球的旋转和瞳孔中心移位、术后角膜上皮再生、年龄等。通过对这些因素的综合考量，可以为眼科临床医生提供更精确的手术规划和个性化的治疗建议，达到更佳的矫正效果，以期提高患者的术后满意度。
In recent years, keratorefractive surgery has achieved great results in the correction of myopia, but some patients have experienced a decline in postoperative visual quality. Astigmatism is a type of refractive error, and its correction is closely related to the postoperative visual quality. In-depth study of the factors affecting the correction of astigmatism not only helps to optimize the surgical process and reduce postoperative complications, but also contributes to achieving better postoperative outcomes. This article outlines the main surgical procedures currently used for correcting astigmatism in keratorefractive surgery, and analyzes several factors that affect the correction effect of astigmatism, including age, the diopter, source, and type of preoperative astigmatism, the setting of intraoperative laser energy, intraoperative rotation of the eyeball, the deccentration of the pupil center, and postoperative corneal epithelial regeneration. By taking a comprehensive consideration of these factors, we can provide ophthalmic clinicians with more accurate surgical planning and personalized treatment recommendations, achieving better correction effects, with the aim of improving patient satisfaction after surgery.
