The corneal shape is significantly altered after LASIK, necessitating new contact lens designs and fitting techniques for optimal postoperative contact lens performance.
Procedures for fitting soft and rigid gas-permeable lenses are described on the basis of the authors' experience. Topographic map options are explored to assess the best curvature and contour data to assist in RGP lens fitting.
Standard soft and rigid lenses are often used with success after LASIK. When fitting standard and reverse geometry RGP lenses, axial topographic maps provide the best curvature values to assist in the fitting of RGP lenses.
Although patients may be apprehensive to pursue contact lens fitting after elective LASIK refractive surgery, new fitting techniques should turn a potentially difficult fitting into a teachable science.
准分子原位角膜磨镶术(LASIK)后角膜形状会发生显著改变,这就需要新的隐形眼镜设计和验配技术,以实现术后隐形眼镜的最佳性能。
根据作者的经验描述了软性和硬性透气性隐形眼镜的验配程序。探索了地形图选项,以评估最佳曲率和轮廓数据,辅助硬性透气性隐形眼镜的验配。
LASIK术后,标准的软性和硬性隐形眼镜常常能成功验配。在验配标准和反几何设计的硬性透气性隐形眼镜时,轴向地形图可提供最佳曲率值,辅助硬性透气性隐形眼镜的验配。
尽管患者在选择性LASIK屈光手术后可能对接种隐形眼镜有所顾虑,但新的验配技术应能将潜在的困难验配转变为一门可传授的科学。
