To describe a long-term outcome of a new technique using the femtosecond laser to assist with keratopigmentation (corneal tattooing).
Nineteen eyes of 18 patients with a history of significant visual disability related to iris defects underwent femtosecond laser-assisted keratopigmentation (FAK) for functional restoration of their visual disabilities. Postoperative visual acuity and symptomatic resolution were collected during their postoperative visits.
After FAK surgery, all patients had improvement in their previous visual-related symptoms. Eighteen of 19 eyes (94%) had improvement in their best-corrected Snellen visual acuity. Eight of 19 eyes (42%) had at least 1 line improvement, 8 of 19 eyes (42%) had at least 2 lines of improvement, and 2 of 19 eyes (10%) had at least 3 lines improvement. The average follow-up period was approximately 60 months.
The FAK technique offers a long-term effective and safe technique for visual disabilities and improves visual acuity in patients with various traumatic iris defects.
描述一种使用飞秒激光辅助角膜染色（角膜纹身）的新技术的长期效果。
18 名患者的 19 只眼因虹膜缺损导致严重视力障碍，采用飞秒激光辅助角膜染色（FAK）技术，以恢复其视力障碍的功能。在术后随访期间收集术后视力和症状缓解情况。
FAK 手术后，所有患者的先前与视力相关的症状均有改善。19 只眼中有 18 只（94%）最佳矫正视力提高。19 只眼中有 8 只（42%）提高至少 1 行，8 只（42%）提高至少 2 行，2 只（10%）提高至少 3 行。平均随访时间约为 60 个月。
FAK 技术为各种创伤性虹膜缺损患者的视力障碍提供了一种长期有效且安全的治疗方法，并提高了患者的视力。
