BACKGROUND
Scarring may follow refractive surgery, causing irregular astigmatism and loss of visual acuity.
METHODS
A case report of scarring and irregular astigmatism occurring in a corneal transplant following photorefractive keratectomy and arcuate incisions is presented.
RESULTS
Following surgical excision of the scar, unaided visual acuity improved from 1/60 to 6/12. Histopathology of the excised scar was obtained.
CONCLUSIONS
Refractive surgery following corneal transplantation may produce scarring. The origin of the scar in the present case has not been established.
背景
屈光手术可能会导致瘢痕形成，引起不规则散光和视力下降。
方法
本文报告了1例在准分子激光原位角膜磨镶术和弧形切口后的角膜移植术中出现瘢痕和不规则散光的病例。
结果
手术切除瘢痕后，裸眼视力从1/60提高到6/12。对切除的瘢痕进行了组织病理学检查。
结论
角膜移植术后进行屈光手术可能会产生瘢痕。本病例中瘢痕的起源尚未明确。
