Abstract
Pseudophakic patients have been found with the ability to read both 6/6 and N5 without a reading addition. An explanation of this phenomenon is offered in terms of the depth-of-focus of the pseudophakic eye. Results of experiments to measure the depth-of-focus of the pseudophakic eye for Snellen letters are compared with theoretical predictions from earlier work, and implications in terms of visual acuity and refractive error are discussed.
