We have analyzed the ultraviolet transmittance of some commercial intraocular lenses (IOLs). The results show differences of wavelength cutoff among them.
The purpose of this study was to measure and compare the ultraviolet light transmittance of different IOLs made out of acrylic hydrophobic, hydrophilic, and hydrophilic with hydrophobic surface materials from different manufacturers.
The spectral transmission curves of eight monofocal IOLs with the same dioptric power of +20.0 diopters were measured using a PerkinElmer Lambda 35 ultraviolet/visible spectrometer. Two IOLs of each type were tested three times. The ultraviolet cutoff wavelength at 10% transmission and the mean values were calculated.
All lenses prevented transmission of ultraviolet C (200 to 280 nm) and B radiation (280 to 315 nm). However, not all IOLs provided the same filtering properties in ultraviolet A (315 to 380 nm). Within the ultraviolet A range, the ultraviolet radiation cutoff wavelength of 10% ranges from approximately 360 to 400 nm. HOYA iSert 250 provided a cutoff wavelength of 398.4 nm; AcrySof SA60AT, 396.2 nm; AcrySof SA60WF, 395.7 nm; CT Asphina 404, 378.34 nm; Tecnis ZCB00, 377.70 nm; CT Lucia 607P, 379 nm; C-Flex 570C, 377 nm; and enVista MX60, 360 nm.
Intraocular lenses of different materials and manufacturers have different ultraviolet transmission characteristics. AcrySof (SA60AT and SA60WF) and HOYA iSert 250 provided the highest ultraviolet radiation transmission; the cutoff wavelength of 10% is close to 400 nm. In contrast, enVista IOL showed the lowest ultraviolet radiation cutoff.
我们分析了一些市售人工晶状体（IOL）的紫外线透过率。结果显示它们之间存在波长截止差异。
本研究的目的是测量和比较不同制造商生产的由丙烯酸疏水、亲水以及具有疏水表面的亲水材料制成的不同人工晶状体的紫外线透过率。
使用珀金埃尔默Lambda 35紫外/可见光谱仪测量了八个屈光度为+20.0屈光度的单焦点人工晶状体的光谱透射曲线。每种类型的两个人工晶状体进行了三次测试。计算了10%透过率时的紫外线截止波长和平均值。
所有晶状体都能阻止紫外线C（200至280纳米）和B辐射（280至315纳米）的透射。然而，并非所有人工晶状体在紫外线A（315至380纳米）范围内都具有相同的滤光特性。在紫外线A范围内，10%的紫外线辐射截止波长约为360至400纳米。豪雅iSert 250的截止波长为398.4纳米；爱尔康AcrySof SA60AT为396.2纳米；AcrySof SA60WF为395.7纳米；蔡司CT Asphina 404为378.34纳米；爱尔康Tecnis ZCB00为377.70纳米；蔡司CT Lucia 607P为379纳米；C-Flex 570C为377纳米；以及眼力健enVista MX60为360纳米。
不同材料和制造商的人工晶状体具有不同的紫外线透射特性。爱尔康（SA60AT和SA60WF）和豪雅iSert 250具有最高的紫外线辐射透射率；10%的截止波长接近400纳米。相比之下，眼力健IOL显示出最低的紫外线辐射截止值。
