Abstract:
One common complaint with natural opacified lenses is the deleterious effects of higher-order ocular aberrations and intraocular scatter, such as halos and starbursts, which are not always remedied with surgery and intraocular lens (IOL) implantation. Blue-light filtering (BLF) IOL filter scatter-prone short-wave light. Here, we determine whether BLF IOL reduce halo and starburst size.
This study was a case-control design, between- and within-subjects (contralateral implantation). Sixty-nine participants with either the BLF IOL (n = 25; AlconSN60AT), clear IOL (n = 24; AlconSA60AT or WF), or both (n = 20) IOL participated. Participants were exposed to a point source of broadband simulated sunlight, which created the appearance of halos/starbursts. Dysphotopsia was measured as the diameter of broadband light-induced halos and starbursts.
A case-control analysis. Halo size was significantly larger (t[35.05] = 2.98, p = 0.005) in participants with the clear control lens (M = 3°55\' ± 2°48\'), compared to the BLF IOL (M = 1°84\' ± 1°34\'). Starburst size was not significantly different between groups. Contralateral analysis. Halo size was significantly smaller (t = -3.89, p = .001) in test eyes with the BLF (M = 3°16\' ± 2°35\') compared to the fellow control eyes (M = 5°42\' ± 3°17\'). Starburst size was also significantly smaller (t = -2.60, p < 0.018) in BLF test eyes (M = 9°57\' ± 4°25\') than the fellow eye with the clear IOL (M = 12°33\' ± 5°25\').
BLF IOL filter short-wave light and mimic retinal screening by the young, natural crystalline lens. Such filtering can reduce some deleterious effects of bright light by decreasing ocular diffusion/halos and starbursts.
摘要:
自然不透明晶状体的一个常见主诉是高阶眼像差和眼内散射的有害影响,比如光环和星暴,这并不总是通过手术和人工晶状体(IOL)植入来补救。蓝光过滤(BLF)IOL过滤易散射的短波光。这里,我们确定BLFIOL是否会减少光环和星爆大小。
这项研究是病例对照设计,受试者之间和内部(对侧植入)。69名参与者使用BLFIOL(n=25;AlconSN60AT),透明IOL(n=24;AlconSA60AT或WF),或两者(n=20)IOL参与。参与者暴露在宽带模拟阳光的点源下,这创造了光环/星暴的外观。视错觉被测量为宽带光诱导的光晕和星暴的直径。
病例对照分析。使用透明对照透镜(M=3°55\'±2°48\')的参与者的光环大小明显更大(t[35.05]=2.98,p=0.005),与BLFIOL相比(M=1°84±1°34)。Starburst大小在组间没有显著差异。对侧分析。与其他对照眼(M=5°42'±3°17')相比,使用BLF(M=3°16\'±2°35\')的测试眼的光环大小明显较小(t=-3.89,p=.001)。BLF测试眼(M=9°57\'±4°25\')的Starburst大小也明显小于(t=-2.60,p<0.018)。
BLFIOL过滤短波光并模拟年轻人的视网膜筛查,天然晶状体。这种过滤可以通过减少眼睛扩散/光晕和星暴来减少亮光的一些有害影响。
