PURPOSE
To report the front corneal versus central and paracentral corneal changes after Bowman layer transplantation for keratoconus in a tertiary hospital in the United Kingdom.
METHODS
Five eyes of 5 patients receiving Bowman layer transplant for advanced keratoconus in Royal Gwent Hospital (Newport, United Kingdom) were included. Preoperative and postoperative visual acuity; Kmax; Kmean, and corneal cylinder in the front cornea, 4.5 mm central, and 6 mm central; and corneal thickness were analyzed.
RESULTS
Corneal flattening and reduction in corneal astigmatism was observed, more marked in the central and paracentral zone, allowing for improvement in best-corrected visual acuity with the aid of visual correction in 4 eyes.
CONCLUSIONS
These results support previous data reporting Bowman layer transplantation as a useful strategy in the treatment of advanced keratoconus and suggest greater attention may be focused on central or paracentral corneal changes.
目的
报告在英国一家三级医院进行Bowman 层移植治疗圆锥角膜后前角膜与中央和旁中央角膜变化。
方法
纳入在英国皇家格温特医院（纽波特）接受 Bowman 层移植治疗晚期圆锥角膜的 5 例 5 只眼。分析术前和术后视力；Kmax；Kmean 和前角膜、4.5mm 中央和 6mm 中央角膜散光；以及角膜厚度。
结果
观察到角膜变平，角膜散光减少，在中央和旁中央区域更为明显，在 4 只眼中借助视力矫正可改善最佳矫正视力。
结论
这些结果支持先前报告 Bowman 层移植作为治疗晚期圆锥角膜的一种有效策略的数据，并表明可能需要更多关注中央或旁中央角膜变化。
