Functional results and photic phenomena with Mini WELL Ready IOL
The study evaluated the clinical outcomes of the Mini WELL Ready extended-depth-of-focus intraocular lens (EDOF-IOL) in 14 cataract patients. The lens provided good postoperative functional results at far and intermediate distances, with high rates of spectacle independence and satisfaction in everyday life. Patients reported little to no dysphotopsia, and the lens improved visual and reading acuity at reading distances.

EDOF wavelength dependence
The latest paper from the David J Apple Lab, titled "The Effect of a Spectral Filter on Visual Quality in Patients with an Extended-Depth-Of-Focus Intraocular Lens," has been accepted for publication in the American Journal of Ophthalmology. The study examines the impact of spectral filters on visual quality in patients with diffractive intraocular lenses, finding that while red filters do not improve distance vision, they can cause visual deterioration at near distances.

Multifocal intraocular lenses (IOLs) have advanced significantly, offering improved visual outcomes and spectacle independence after cataract surgery. These lenses divide light into different focuses, enhancing near vision but potentially causing halos, glare, and lower contrast sensitivity. Recent research aims to optimize their optical design, and careful patient selection and surgical technique are crucial for success.
In publication, Sep 07, 2017 Hydrophilic acrylic IOLs and Lamellar keratoplasty
Researchers at the David J Apple International Laboratory for Ocular Pathology analyzed 13 hydrophilic intraocular lenses (IOLs) that became opacified after posterior lamellar keratoplasty, finding that the opacification was caused by calcium phosphate deposits on the IOL surface. This opacification significantly deteriorated the optical quality of the IOLs. The study suggests that the instillation of air or gas into the anterior chamber during these procedures increases the risk of IOL opacification, and recommends avoiding hydrophilic acrylic IOLs in patients who may require such procedures.
