PURPOSE: To investigate the effects of light scattering from the surface of hydrophobic acrylic intraocular lenses (IOLs) on visual function. METHODS: A 67-year-old man was implanted with an IOL (MA60BM) in January 1998, but became aware of decreased visual function in May 2008. Observation with a slit lamp revealed light scattering throughout the entire optic of the IOL, which was extracted and replaced. Postoperative visual function improved at 1 month. The cause of light scattering was investigated with a focus on water permeating the IOL material. To confirm the effect of light scattering on visual function, light transmission of the extracted IOL was measured in physiological saline at 33°C, and the simulated retinal image was evaluated in a model eye. RESULTS: Observation of the extracted IOL showed light scattering from the optic surface layer, the main cause of which was phase-separated water within the IOL material. Light transmission in the extracted IOL was 16.3% lower than that in an unused IOL in the visible range. Moreover, the simulated retinal image was hazy compared to that of the unused IOL. CONCLUSION: Severe surface light scattering from an IOL optic may decrease visual function. |
