Geometry of Modern Presbyopia-Correcting Intraocular Lenses and Changes in Haptic–Capsular Bag Behavior According to Compression and Different Well Diameters: A Bench Study Using Computed Tomography

The laboratory experiments highlight differences in the haptics, the OHJ geometric characteristics, and behavior of samples in different well diameters. The results support the idea that specific IOL designs may have advantages or disadvantages depending on anatomical dimensions. We cannot make any classification or rating (good versus bad) for clinical practice on the basis these experimental results, as many other factors play a role. However, knowledge of IOL geometry seems important to select the best option in each individual case.
