Clinical study of laser in situ keratomileusis for treatment of hypermetropia / 眼科新进展

ABSTRACT

Objective　To evaluate therapeutic effect and opportunity of laser in situ keratomileusis(LASIK) for treatment of hypermetropia.Methods　Three hundred and ninety hypermetropia eyes were treated with LASIK using solid excimer laser instrument(made in Novatec Corporation, USA),and were reexamined at 1,3,6 and 12 months after LASIK.Results　Therapeutic effect of LASIK was more remarkable, stable and reliable, that of other methods in treating +2.00～+10.00D hypermetropia and astigmatism, and the rate and degree of refraction regression were small. The diopter has been stable in 6～12　months after LASIK. Diopter of 87 percentage of all eyes≤+2.00D, and 61 percentage≤+1.00D. LASIK had shorter recovery time, more gently operation reaction, more remarkable droping of diopter than other methods. Elevation of vision was remarkable after LASIK. Elevation of vision of amblyopia children who were treated with LASIK was quicker and more remarkable after treatment of amblyopia than that of other amblyopia children who were not treated with LASIK.Conclusion　At present, LASIK is the best therapeutic method to treat hypermetropia.
