PURPOSE
To describe a case of postoperative trabeculectomy-induced corneal astigmatism treated with femtosecond laser-assisted astigmatic keratotomy.
METHODS
After trabeculectomy, the patient demonstrated change in manifest refraction from -0.5 diopters preoperatively to mixed astigmatism of -3.5 + 5.25@100 postoperatively and a decrease in uncorrected distance visual acuity from 20/60 preoperatively to 20/200 at 1 month postoperatively. Because the patient was intolerant to spectacle use, she underwent femtosecond laser-assisted astigmatic keratotomy.
RESULTS
After astigmatic keratotomy there was improvement in corneal topographic astigmatism from 4.15 to 0.81 diopters with uncorrected distance visual acuity of 20/60(-2) and manifest refraction of -0.75 + 1.0@90 at 3 months postoperatively. There were no intraoperative or postoperative complications.
CONCLUSIONS
Femtosecond laser-assisted astigmatic keratotomy may be considered in eyes with postoperative trabeculectomy-induced mixed astigmatism.
目的
描述一例经飞秒激光辅助散光切削术治疗的术后小梁切除术后角膜散光。
方法
小梁切除术后，患者的显斜视从术前的-0.5 屈光度变为术后的混合散光-3.5+5.25@100，未矫正远视力从术前的 20/60 下降至术后 1 个月的 20/200。由于患者无法耐受眼镜使用，因此接受了飞秒激光辅助散光切削术。
结果
散光切削术后，角膜地形图散光从 4.15 降至 0.81 屈光度，未矫正远视力为 20/60(-2)，术后 3 个月的显斜视为-0.75+1.0@90。术中及术后均无并发症。
结论
对于术后小梁切除术后引起的混合性散光眼，可以考虑飞秒激光辅助散光切削术。
