Transmittance characteristics of ultraviolet and blue-light-filtering intraocular lenses

Abstract: The absorption characteristics of some UV and blue-light-filtering IOLs resembled those of the crystalline lens, but some differed. Long-term clinical trials should be performed to determine how blue-blocking IOLs affect the risk for progression of age-related macular degeneration.

“…The spectral transmittance values of the Alcon clear and/or yellow-tinted IOLs, the Hoya clear and/or yellowtinted IOLs, and the Kowa yellow-tinted IOLs have been reported previously [11,[15][16][17][18][19]. To the best of our knowledge, no transmission characteristics of the IOLs identified in the current study (Fig.…”

“…To estimate the hazards of sunlight to the retina, the BLI values and t max values were calculated for both aphakic and phakic eyes based on the guidelines provided by the American Conference of Industrial Hygienists [22,23] and by the International Commission on Non-Ionizing Radiation Protection [18], and for pseudophakic eyes using the percent transmittance data for the IOLs obtained in the current study (Table 1). All IOLs tested had smaller BLI values and longer t max values compared to those for aphakic eyes (15.00 mW/cm 2 and 0.67 s, respectively).…”

“…19 However, previous studies mainly focused on yellow-tinted blue light-filtering IOLs, such as the Acrysof SN60AT Natural (Alcon Laboratories, Inc.) and the Hoya AF-1(UY) YA-60BB (Hoya Surgical Optics, Inc.); the studies found that the transmission rates were slightly higher than that of a middle-aged human lens (approximately 5% at 400 nm and 70% at 500 nm). [43][44][45][46] In contrast, we evaluated an orange-tinted blue light-filtering IOL, the PC 440 Y Orange Series IOL, which is characterized by more powerful spectral absorption properties than a human lens, and compared the results with those of a conventional clear UV lightfiltering IOL, the PC 430 Elite Series IOL. [14][15][16][17][18][19][44][45][46] We evaluated the scotopic and photopic visual acuity, contrast sensitivity, color discrimination, and potential postoperative visual symptoms.…”

“…Based on the specific color of the chromophore, the Orange Series IOL is supposed to mimic more closely the protective physiologic properties of a middleaged human lens (approximately 60 years of age), resulting in less chromatic aberration and glare disability and an overall improvement in visual performance. 43 Laboratory studies measuring transmittance characteristics [43][44][45][46] showed that this IOL has excellent light-attenuation properties with absorption rates of approximately 90% at 427 nm and 43% at 500 nm, being even more powerful than commonly available blue light-filtering IOLs. This might be of interest because blue-light hazard peaks at approximately 430 nm.…”
