摘　　要：目的:探讨配戴角巩膜接触镜对圆锥角膜患者视力和角膜参数的影响。方法:前瞻性研究。共纳入43例(83眼)圆锥角膜患者。配戴角巩膜接触镜,并分别在戴镜前、戴镜3、6 mo后行裂隙灯检查、客观验光和主观验光、裸眼视力(UCVA)和最佳矫正视力(BCVA)、角膜曲率(Kmax、K1和K2)、中央角膜厚度和内皮细胞计数检查。结果:配戴6 mo框架眼镜后平均BCVA(LogMAR)为0.34±0.23,角巩膜接触镜为0.03±0.05(P<0.001)。戴镜6 mo后,Kmax由52.80±5.93 D变为51.51±5.64 D(P<0.001),角膜中央厚度由483.84±34.69μm变为476.28±35.38μm(P<0.001),角膜中央细胞计数由2559.18±275.7 cells/mm^(2)变为2572.73±274.3 cells/mm^(2)(P<0.001)。结论:临床中角膜参数未发生明显变化,角巩膜镜可显著提高视力,且可安全用于圆锥角膜患者。AIM:To investigate the effect of wearing corneoscleral contact lens on visual acuity,and corneal parameters in keratoconus patients.METHODS:In this prospective study,43 cases(83 eyes)with keratoconus were included and examined.A corneoscleral contact lens was fitted,and thorough exams were carried out at baseline,3 and 6 mo after wearing lenses,including slit lamp examination,objective and subjective refraction,uncorrected visual acuity(UCVA),and best-corrected visual acuity(BCVA),keratometry(Kmax,K1 and K2),central corneal thickness and endothelial cells count.RESULTS:Mean BCVA(LogMAR)improved from 0.34±0.23 with the spectacles to 0.03±0.05 with the corneoscleral contact lenses in 6 mo(P<0.001).Kmax changed from 52.80±5.93 D to 51.51±5.64 D in 6 mo(P<0.001),central corneal thickness changed from 483.84±34.69μm to 476.28±35.38μm(P<0.001),and endothelial cell count changed from^(2)559.18±275.7 cells/mm^(2) to 2572.73±274.3 cells/mm^(2) after wearing corneoscleral contact lens for 6 mo(P<0.001).CONCLUSION:Corneoscleral lenses could significantly increase visual acuity,since there were no clinical noticeable changes in the corneal parameters,this lenses can be used safely in patients with keratoconus.
