摘要
目的比较中高度散光患者配戴框架眼镜和透气性硬性接触镜(RGPCL)的主客观视觉质量。方法选取2008年6月-2011年5月中高度角膜散光20例共40只眼进行角膜地形图、综合验光仪验光等检查后,选择合适试戴片作配适评估并定制RGPCL。要求患者戴镜后1周、1个月、3个月和6个月复查,记录矫正视力、镜片配适、眼部情况,并在第4次复查时进行对比敏感度视力检查及主观问卷调查。结果 RGPCL矫正视力优于框架眼镜,但两者对比敏感度视力在各空间频率均无明显差异。主观评分时,远视力两者无明显差别;中距离视力框架眼镜评分(3.825±0.245)分,RGPCL评分(3.525±0.302)分,差异有统计学意义(t=5.339,P=0.000);近距离视力框架眼镜评分(3.795±0.233)分,RGPCL评分(3.690±0.194)分,差异有统计学意义(t=3.462,P=0.030)。有45%患者选择RGPCL为主要配戴方式;40%患者选择RGP CL和框架眼镜交替使用的方式;10%患者选择仅在有特殊社交需求时使用RGPCL;另5%患者放弃使用RGPCL。结论 RGPCL和框架眼镜矫正中高度角膜散光均能取得较满意效果,在中近距离精细作业时框架眼镜矫正视力更为稳定清晰。但由于RGPCL在成像质量和外观上的优势,多数患者仍愿意坚持配戴RGPCL。
Objective To explore whether spectacles or rigid gas-permeable （RGP） contact lenses provide better visual performance for moderate to severe astigmatism. Methods Between Jtme 2008 and May 2011, 20 individuals （40 eyes） were fitted with both RGP lenses and spectacles. They first underwent corneal topography and refractometry, then were fitted with RGP trial lenses and lastly fitted with RGP lenses. When regularly followed up, the corrected visual acuity, wearing condition and eye health were evaluated respectively. For each type of lens, contrast visual acuity was evaluated. Each subject was asked to select the lens type of choice and to rate quality of vision in day-to-day activities through a questionnaire. Results The corrected visual acuity with RGP lenses was better than that with spectacles. But there was no difference in contrast visual acuity in all spatial frequency. Subjectively, there was no difference in vision, but most of the subjects prefer the computer-visual acuity and reading-visual acuity corrected by spectacles. About 40% of patients choose RGP contact lens as the main corrected method, and 45% of patients preferred using RGP lenses and spectacles alternately. About 10% of patients only wear RGP lenses when it was necessary. Two patients dropped out. Conclusions Both RGP lenses and spectacles leads to good results in correcting moderate to severe astigmatism. Though spectacles get higher scores in near vision, because of the better visual performance and appearance offered by RGP contact lens, a majority of patients can insist on wearing it.
