A 42-year-old man had Intacs (Addition Technology Inc.) implantation for early pellucid marginal degeneration (PMD). Two Intacs segments (0.45 mm thickness) were inserted uneventfully in the fashion typically used for low myopia correction (nasal-temporal). Eleven months after the procedure, the uncorrected visual acuity was 20/200, compared with counting fingers preoperatively, while the best spectacle-corrected visual acuity improved to 20/25 from 20/50. Corneal topographic pattern also improved. Although the results are encouraging, concern still exists regarding the long-term effect of this approach for the management of patients with PMD.
一名42岁男性因早期透明边缘变性（PMD）接受了Intacs（Addition Technology Inc.）植入手术。以通常用于低近视矫正的方式（鼻侧-颞侧）顺利插入了两个Intacs节段（厚度为0.45毫米）。术后11个月，未矫正视力为20/200，术前为指数视力，而最佳眼镜矫正视力从20/50提高到了20/25。角膜地形图也有所改善。尽管结果令人鼓舞，但对于这种治疗PMD患者的方法的长期效果仍存在担忧。
