摘　　要：目的研究硬性透气性角膜接触镜（RGP）对矫正角膜裂伤愈合后的不规则散光的作用。方法角膜裂伤愈合后继发不规则散光20例（20眼），分别验配框架眼镜及RGP，记录其矫正视力，并在配戴RGP后随访观察3个月。结果所有试验眼在配戴RGP后，较配戴框架眼镜视力平均提高（4．40±0．88）行（标准对数视力表）。对比配戴框架眼镜，配戴RGP后的矫正视力明显提高，差异具有统计学意义（t=13．58，P=0．00）。结论配戴RGP能提高角膜裂伤愈合后不规则散光的患眼的视力。Objective To study the effect of rigid gas permeable contact lens （RGP） on irregular astigmatism caused by corneal laceration. Methods twenty eyes of 20 patients with irregular astigmatism caused by cornea/ laceration were collected. The fram glasses and RGP fitting were performed, and the corrected visual acuity was recorded. The follow-up time was 3 months. Results Compared with wearing frame glasses, the corrected visual acuity of all the eyes had an average increase of （4.40 ± 0.88 ） lines when wearing RGP. And the difference was statistically significant （ t = 13.58, P = 0.00）. Conclusion Wearing RGP could improve the visual acuitv of eves with irregular astigmatism caused by corneal laceration.
