摘　　要：目的探讨Q值调整的个性化准分子激光原位角膜磨镶术（F-CAT）治疗中高度散光的安全性和有效性。方法采用德国Wavelight公司的鹰视酷眼准分子激光系统，对36例（53只眼）中高度散光进行F-CAT手术治疗，术前等值柱镜度数-2．00～-6．00D，平均（-2．65±0．93）D。结果术后12个月的平均裸眼视力为1．01±0．24，裸眼视力达到或超过术前矫正视力48只眼（90．6％）。术后散光度较术前明显改善，除2只眼因角膜厚度所限，分别残留-1．5D，-1．75D散光，其余患者术后1年复查散光度均〈1D，且一直较为稳定。术前Q值介于-0．05～-0．50，其中Q1值-0．29±0．10，Q2值-0．33±0．12。目标Q值-0．15～-0．45，平均-0．29±0．09。术后12月角膜中央30度范围内Q值与术前球镜和柱镜之和相关性较强。结论F-CAT治疗中高度散光安全有效，视觉质量较好。Objective To investigate the safety and validity of fine adjusted-customized ablation treatment（F-CAT） for moderate and high astigmatism.Methods 36patients （53 eyes） of moderate and high astigmatism ranged from -2.00D to -6.00D（The mean cylindrical refraction were -2.65 ± 0.93D） were treated with German Wavelight Allegretto wave Eye-Q bye means of F-CAT.Results The mean uncorrected Visual acuity was 1.01 ± 0.24 at 12 months after operation, 48 eyes（90.6%） reached or exceeded the pre-operation corrected visual acuity, the astigmatism was clearly amended except 2 eyes had still- 1.5D and -1.75D cylindrical refraction because of the limitation of cornea thickness, other patients＇ cylindrical refractions were lower 1D at one year after operation and were stable.The pre-operation Q-value ranged from -0.05 to -0.50. and Q1-value was -0.29 ± 0.10. Q2-value was -0.33 ± 0.12. the average of target Q-value was -0.29 ± 0.09（rang from -0. 15- -0.45）. the Q-value with 30i,vertex of conea had good relativity with the summation of pre-operation spherical and cylindrical refraction. Conclusion F-CAT treatment for moderate and high astigmatism is effective, safe and patients have better visual quality.
