Evaluation of clinical efficacy of accommodating intraocular lens implantation in pseudophakic eyes from the perspective of morphological studies

The accommodating intraocular lens (AIOL) is designed to simulate the accommodation of the crystalline lens and satisfy patients by its ability to focus on an object at any distance independent of spectacles.However, near vision in the short-term or long-term future of some patients with AIOLs is not good in clinical practice and there is still no consistent conclusion as to whether they can restore sufficient accommodation.Most clinical evaluations of AIOL performance have been based on visual function, such as the testing of near visual acuity and subjective measurements of accommodation, but these tests may not determine whether the lenses are actually working according to the principle of their design.With the rapid development of imaging technologies, the performance of AIOLs can be observed from the perspective of morphology.This article described the biometry of the anterior segments in the subjects with AIOL during accommodation in order to understand the actual clinical effects of AIOLs.
