Physico-chemical parameters of Silicone Oil
The study examined the effects of biological media on silicone oil used as an intraocular tamponade in retinal detachment surgery. It found that prolonged exposure to the eye does not alter the oil's physicochemical parameters, but the addition of high-molecular-weight components may decrease emu...

Polyimide cannulas
Researchers compared the injection times of high-viscosity silicone oils using polyimide and metal cannulas. Polyimide cannulas significantly reduced injection times, allowing for the use of ultra-high-viscosity oils, and prewarming the oil further decreased injection times.

Pupil dynamics
This study compares pupil size after three different strategies for intraocular lens (IOL) fixation: anterior iris-fixation, retropupillary iris-fixation, and in-the-bag implantation. The results show that all three strategies do not impair pupil constriction in normal light conditions, but retro...
