UNASSIGNED: This observational cross-sectional study included 59 participants (21 males and 38 females) within the age of 18 to 30yearsand refractive error between +3.00D to -6.00D took part in this study. Subjects with a previous history of non-strabismic binocular vision anomaly, astigmatic error, pathological eye problems, ocular surgery or trauma were excluded from the study. The subjects were allowed to estimate their refractive error with DialVision eyeglasses followed by CSR, which was performed by a single examiner. The visual and refractive outcomes of SR and CSR were collected and analyzed.
UNASSIGNED: The study participants mean age was 22(2) years.The comparison of visual acuity and duochrome between SR and CSR using Paired T test showed a statistically significant difference (P<0.01). Visual acuity attained from SR resulted in a mean acuity of 0.14(0.05) logMAR compared to CSR 0.002(0.007) logMAR. Duochrome test identified 92% of participants being under corrected with SR. No statistically significant difference was observed in contrast sensitivity and cover test (P>0.01).
UNASSIGNED: Visual acuity with SR was acceptable but wasn\'t better than CSR. Appreciable under correction of refractive error with SR raises concern. Encouraging a patient to correct their own refractive error without a comprehensive eye examination can lead to various adverse effects. Even though SR might bring a brief relief towards the burden of uncorrected refractive error, dispensing spectacle based on standard refraction procedure is imperative for good visual performance.
■这项观察性横断面研究包括59名18至30岁的参与者(21名男性和38名女性)和+3.00D至-6.00D的屈光不正参与了这项研究。既往有非斜视双眼视觉异常史的受试者,散光误差,病理性眼部问题,眼科手术或外伤被排除在研究之外.允许受试者使用DialVision眼镜和CSR来估计他们的屈光不正,这是由一名审查员执行的。收集并分析SR和CSR的视觉和屈光结果。
■研究参与者平均年龄为22(2)岁。SR和CSR的视力和十二指肠色素比较采用配对T检验,差异有统计学意义(P<0.01)。与CSR0.002(0.007)logMAR相比,从SR获得的视敏度平均为0.14(0.05)logMAR。Duochrome测试确定92%的参与者被SR校正。对比敏感度和覆盖试验差异无统计学意义(P>0.01)。
■SR的视力可以接受,但不如CSR。对SR矫正屈光不正的重视引起了人们的关注。鼓励患者在没有全面眼睛检查的情况下纠正自己的屈光不正可能导致各种不利影响。尽管SR可能会给未矫正的屈光不正带来短暂的缓解,基于标准屈光程序的眼镜分配对于良好的视觉性能是必不可少的。
