On slit lamp examination, the binocular IOL optics showed homogenous opacification. After extraction of the IOLs, the IOL opacification disappeared during dry storage at 4°C. To investigate the changes in IOL opacification according to temperature and hydration, an extracted IOL was stored in either dry conditions or normal saline at 4°C, room temperature, or 37°C for 24 hours, and then the degree of haziness was examined. To investigate the impact of an opaque optic on visual function, light transmission was performed using an ultraviolet-visible spectrophotometer (U-3000, Hitachi High-Technologies Corp., Tokyo, Japan).Results: The extracted IOL optics at 4°C, room temperature, and 37°C were transparent at dry conditions. When the dried IOL was immersed in normal saline at room temperature and 37°C, opacification appeared. However, when the dried IOL was immersed in normal saline at 4°C, opacification of the IOL did not appear. When compared with the control, light transmission of the extracted IOLs from the right and left eyes stored in 37°C normal saline decreased by 4.7% at 453 nm and by 5.1% at 482 nm, respectively.Conclusion: In acrylic hydrophobic IOLs, optic opacification can occur depending on temperature and hydration conditions.Keywords: intraocular lens, whitening, scattering, opacification, hydrophobic lens, acrylic lensKang JYSong JHLee SJDove Medical Pressarticleintraocular lenswhiteningscatteringopacificationhydrophobic lensacrylic lensOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 3343-3349 (2020)
