【 摘 要 】

AIM: To evaluate the effect of rigid gas permeable contact lens(RGPCL)for high myopia with corneal astigmatism.

METHODS: Totally 72 patients(118 eyes)with high myopia with corneal astigmatism were fitted with RGPCL, and the corrected visual acuity were recorded after one month. The MPMVA(maximum plus to maximum visual acuity)were recorded by comprehensive refraction. The corrected visual acuity of RGPCL was compared with the MPMVA.

RESULTS: There were 17 eyes of 4.7(14.4%), 52 eyes of 4.8(44.1%)and 49 eyes of 4.9-5.0(41.5%)in comprehensive refraction. There were 6 eyes of 4.7(5.1%), 21 eyes of 4.8(17.8%)and 91 eyes of 4.9-5.0(77.1%)in RGPCL corrected visual acuity. RGPCL corrected visual acuity of(4.9-5.0)improved in 42 eyes(35.6%), and the difference was statistically significant.

CONCLUSION: The application of RGPCL can correct high myopia with corneal astigmatism, and has an excellent clinical result.
