“…In patients with asteroid hyalosis, and who have had cataract surgery with implantation of a silicone IOL, whitish-gray deposits with a granular texture can accumulate as a crust-like layer on the posterior surface of the lens. 6 This material has been identified to be hydroxyapatite, consisting of calcium and phosphate. 1 , 2 It is believed to either be derived from the asteroid bodies or from a similar process that resulted in the vitreous condition itself.…”

Purpose To report a rare case of intraocular lens (IOL) calcification in the presence of asteroid hyalosis with in-vivo measurements of straylight before and after treatment. Observations A patient with asteroid hyalosis presented with complaints of disability glare due to calcifications on the posterior surface of the IOL. Straylight, measured with the C-Quant, was 8.2x elevated compared to normal (log(s) 2.08). Dissolution of the posterior face IOL deposits was performed with a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, resulting in a significant decrease in straylight (log(s) 1.76), congruent with the patient's subjective improvement. Conclusions and importance To the best of our knowledge, this is the first report describing a patient with an opacified IOL due to asteroid hyalosis with in-vivo measurements of straylight before and after treatment. It illustrates that awareness of glare complaints in patients with an opacified IOL is important, documentation with C-Quant measurements may be helpful in indicating treatment, evaluating the treatment, and following up the patient, and treatment with a Nd:YAG laser may dissolve the opacifications to a clinically satisfactory level.

“…Asteroid hyalosis is characterized by bright asteroid bodies floating in the vitreous body. [6] Its prevalence is approximately 1% and increases with aging. [8] Analysis of the asteroid bodies demonstrated that calcium and phosphorus were its main components.…”

“…[1234] The opacification is characterized by progressive accumulation of white granular or fleck-like deposits that is localized to the posterior optic surface of the silicone IOL. [5] Although removal the calcification deposits using neodymium:yttrium–aluminum–garnet (Nd:YAG) laser is simple and safe, attempts to use Nd:YAG laser treatment have often been associated with unsatisfactory results or immediate re-accumulation of the deposits on the posterior surface of the IOL[126] IOL exchange have been considered the definitive treatment for the silicone IOL opacification. [1467] However, the method is technically difficult and associated with increased risk of complications.…”

An 86-year-old Asian man with asteroid hyalosis presented with decreased vision in the left eye. He underwent phacoemulsification and implantation of silicone intraocular lens (IOL) in the left eye 18 years ago, and also received neodymium:yttrium–aluminum–garnet (Nd:YAG) laser 3 years ago. At presentation, his corrected visual acuity (CVA) was 20/1000 in the left eye. Slit-lamp examination showed white-gray membranous deposits on the posterior IOL surface. The deposits were removed using Nd:YAG laser treatment. One week later, his CVA improved to 20/30, and opacity of the posterior IOL surface was removed. Six months later, his CVA was 20/30, and visual axis was clear. This case suggests that Nd:YAG laser treatment can be a viable option in some patients with posterior surface opacification of silicone IOL associated with asteroid hyalosis, especially in those who are a poor candidate for IOL exchange due to old age or compromised general condition.

Eintrübung von Intraokularlinsen: Erkenntnisse aus dem Labor und der Klinik

Zusammenfassung Hintergrund Das Spektrum der Komplikationen beim Einsatz von Intraokularlinsen (IOL) ist heute ein anderes als zur Zeit ihrer Einführung. Trübungen im IOL-Material werden vermehrt als Explantationsgrund in der Literatur beschrieben. Ziel der Arbeit Diese Arbeit soll einen Überblick über die verschiedenen Formen von IOL-Materialeintrübungen geben. Material und Methoden Die heute relevanten Formen von IOL-Materialeintrübungen und deren Auswirkungen auf die optische Abbildungsqualität wurden zusammengestellt. Ergebnisse und Diskussion Als Grund für eine Eintrübung steht bei hydrophilen IOL die Kalzifikation im Vordergrund, während bei hydrophoben IOL v. a. über die Entstehung sog. „Glistenings“ berichtet wird. Die meisten Materialeintrübungen beeinflussen verschiedene optische Parameter und führen zu einem erhöhten intraokularen Streulicht. Im Falle einer störenden Materialeintrübung besteht die einzige Therapieoption in einem Austausch der eingetrübten IOL.
