角膜激光术后人工晶状体屈光度预测的研究进展

Research Progress in the Prediction of IOL Refraction after Corneal Laser Surgery

摘要: 随着全球屈光不正患者的日益增多，角膜激光手术迅速发展。角膜激光手术后白内障手术数量也在逐年增加，人工晶状体(Intraocular Lens, IOL)屈光度的准确预测成为眼科医师面临的一个日益严峻的挑战。这些患者通常对视觉质量有很高的期望。然而，传统的IOL屈光度预测公式计算的结果并不准确。在可预见的将来，在人口老龄化的情况下，角膜激光术后需要进行白内障手术的患者数量预计会相应增加。对于这些患者，眼科医师不可避免地面临精准预测IOL屈光度的问题。在我国，角膜激光手术已开展30年，绝大部分近视患者接受的近视矫正方法为准分子激光角膜表面切削术(photo refractive keratectomy, PRK)、准分子激光原位角膜磨镶术(laser in situ keratomileusis, LASIK)和飞秒激光小切口角膜基质透镜取出术(small incision lenticule extraction, SMILE)。本文旨在总结并推荐目前可用的上述角膜激光手术后IOL屈光度预测方法。

Abstract: With the increasing number of patients with refractive errors worldwide, corneal laser surgery is growing rapidly. The number of cataract surgeries following corneal laser surgery is also increasing yearly, and accurate prediction of IOL refraction has become an increasing challenge for ophthal-mologists. These patients often have high expectations of visual quality. However, traditional IOL refraction prediction formulas have inaccurate calculated results. In the foreseeable future, the number of patients requiring cataract surgery after corneal laser surgery is expected to increase accordingly in an aging population. For these patients, ophthalmologists inevitably face the problem of accurately predicting IOL refraction. In China, corneal laser surgery has been performed for 30 years, and the vast majority of myopia patients receive myopia correction by excimer laser photo refractive keratectomy, excimer laser in situ keratomileusis, and femtosecond laser small incision lenticule extraction. The purpose of this paper is to summarise and recommend the currently available methods for predicting IOL refraction after these corneal laser procedures.
