Crystalline lens accommodation in vivo quantified in 3-D by OCT, published in Biomedical Optics Express
We used 3-D quantitative OCT to quantify the anterior segment biometry and crystalline lens surface topographies in humans as a function of accommodation. Relationships between anterior and posterior lens surface aberrations were investigated. For example, the astigmatic axis differed on average ~80 deg between the anterior and posterior lens surfaces and the elative anterior/posterior lens astigmatic angle shifts (10-20 deg) with accommodation. The study has been just published in Biomedical Optics Express.
