我们通过准分子激光手术治疗了 13 只眼睛（12 名患者），通过线性角膜 T 形切除术矫正散光。所有眼睛均接受至少三个月的随访。我们使用新开发的传输系统和特殊的接触掩模来传输 193 nm 准分子光。获得高达 4.16 屈光度的散光矫正。实际校正与生物力学理论预测的预期值非常吻合。随着时间的推移屈光变化与刀切口后观察到的不同，表明不同的修复机制。所有眼睛中充满整个 T 型切除的上皮栓塞持续了一年多。
We treated 13 eyes (12 patients) with excimer laser surgery for correction of astigmatism using linear corneal T-excisions. All eyes were followed up for a minimum of three months. We used a newly developed delivery system and special contact masks to deliver the 193-nm excimer light. Astigmatic corrections of up to 4.16 diopters were obtained. The actual corrections corresponded well with the intended values as predicted by a biomechanical theory. The refractive change over time was different than that observed after knife incisions, suggesting different repair mechanisms. An epithelial plug filling the whole T-excision persisted for over one year in all eyes.
