Corneal transplant surgeries have a broad range of indications with outcomes largely dependent on surgeon experience. Traditional manual techniques have certain limitations pertaining to the preparation of donor tissue and the recipient bed that might affect the predictability of visual outcomes. Use of lasers for keratoplasty procedures not only improves the repeatability and consistency of the technique, but also enables the surgeon to control the thickness and shape of the transplant tissue tailored to the specific condition. Despite the advantages, cost-effectiveness and technical know-how remain the major challenges. We discuss the various techniques of laser-assisted keratoplasties with respect to their methods, precision, and efficacy in various corneal indications.
角膜移植手术有广泛的适应证,其结果在很大程度上取决于外科医生的经验。传统的手动技术在供体组织和受者床的准备方面存在一定的局限性,这可能会影响视觉结果的可预测性。角膜移植术中使用激光不仅提高了技术的可重复性和一致性,还使外科医生能够根据具体情况控制移植组织的厚度和形状。尽管有这些优势,但成本效益和技术诀窍仍然是主要挑战。我们讨论了各种激光辅助角膜移植技术,包括其方法、精度和在各种角膜适应证中的效果。
