Supplementary Material for: Phacoemulsification wound burn and its management

Introduction: the production of ultrasonic energy during phacoemulsification is associated with heat generation that could damage ocular tissues, particularly at the corneoscleral wound site. Case presentation: an 89-year-old patient with senile hypermature cataract and Fuchs endothelial dystrophy developing severe thermal corneoscleral injury during phacoemulsification. At presentation visual acuity was finger count at 40 cm and there was a 1x2-mm area of corneal melting at the corneal tunnel with diffuse corneal oedema. After 1 month a temporal circular corneal patch graft was applied to the corneal burn. A penetrating keratoplasty was performed 16 months after the first surgery. Conclusion: Corneal surgery, including lamellar patch grafts and full-thickness penetrating grafts, could be used, when necessary, to restore the cornea’s integrity. These procedures could eliminate corneal scarring, decrease astigmatism, and improve vision in patients with phacoemulsification burns.引言：超声乳化术（phacoemulsification）过程中产生的超声能量会伴随热量生成，该热量可能损伤眼部组织，尤其易累及角巩膜切口部位。 病例报告：1名89岁老年性过熟期白内障合并Fuchs内皮营养不良（Fuchs endothelial dystrophy）的患者，在超声乳化术中出现严重角巩膜热损伤。就诊时患者视力为40cm处数指，角膜隧道处可见1×2mm的角膜融解区，伴弥漫性角膜水肿。术后1个月，医师为该角膜烧伤患者实施了颞侧圆形角膜板层移植片移植术。首次手术后16个月，患者接受了穿透性角膜移植术。 结论：必要时可通过角膜手术（包括板层移植片移植与全层穿透性角膜移植）恢复角膜完整性。此类手术可消除角膜瘢痕、降低散光程度，并改善超声乳化术烧伤患者的视力。
