PURPOSE
To describe a novel surgical technique for the management of progressive keratoconus by simultaneous femtosecond laser-assisted Myoring implantation and accelerated corneal intrastromal collagen cross-linking with Dextran Free Riboflavin.
METHODS
After creating a corneal pocket with femtosecond laser, Dextran Free Riboflavin was injected into the intrastromal pocket. Then the Myoring was implanted in the corneal pocket and accelerated corneal intrastromal collagen cross-linking was performed with no epithelial debridement.
RESULTS
The cornea remained clear and the central keratometry was decreased significantly with marked improvement in uncorrected visual acuity up to two years following treatment. Anterior segment OCT revealed good centration and intended implant depth with desirable increase in the corneal stromal reflectivity confirming effective collagen cross-linking.
CONCLUSION
Simultaneous femtosecond laser-assisted Myoring implantation and accelerated corneal intrastromal collagen cross-linking with Dextran Free Riboflavin is a safe and effective technique for management of keratoconus and improving vision.
目的
描述一种通过飞秒激光辅助同步植入Myoring并使用无右旋糖酐核黄素加速角膜基质内胶原交联来治疗进行性圆锥角膜的新型手术技术。
方法
用飞秒激光制作角膜基质袋后，将无右旋糖酐核黄素注入基质袋内。然后将Myoring植入角膜基质袋，并在不进行上皮清创的情况下进行加速角膜基质内胶原交联。
结果
治疗后两年内，角膜保持清晰，中央角膜曲率显著降低，未矫正视力明显改善。眼前节光学相干断层扫描显示植入物居中良好，植入深度理想，角膜基质反射率增加，证实胶原交联有效。
结论
飞秒激光辅助同步植入Myoring并使用无右旋糖酐核黄素加速角膜基质内胶原交联是一种治疗圆锥角膜和改善视力的安全有效技术。
