Filter by:Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). Implantation of the IOLs is bilaterally.
This is a prospective, non-randomised, controlled, single-surgeon, single-center post-market clinical follow up study whereby patient undergoing routine cataract surgery will have bilateral implantation of a recently introduced TGA (Therapeutics Goods Authority, Australia) approved trifocal intraocular lens FineVision Evo (PhysIOL, Liège, Belgium). The primary and secondary effectiveness data for visual acuity, defocus curves, contrast sensitivity and any adverse events will be collected.
The study is a prospective randomised controlled study. The patients get monolateral IOL implantation of POD F GF and POD F in the contralateral eye. Both IOLs are trifocal IOLs consisting of the same optical design. The difference between the IOLs is the material (hydrophilic and hydrophobic). To decide which eye receives POD F and which eye receives POD F GF, a randomization table will be provided to the principle investigator.
With the rapid growing aging population, age-related eye diseases including cataract are becoming more prevalent. The demand for cataract surgery and post-surgical care posed enormous financial burdens to the government. Vitamin C, also known as ascorbate, is a highly effective antioxidant which may help to protect the cells including the crystalline lens components from oxidative damage, which is believed to be one of the causes of senile cataract. Lycium barbarum, on the other hand, contains lutein and zeaxanthin which can filter the phototoxic blue light and neutralize the reactive oxygen species, thus provide a protective effect against cataract formation. This study aims to determine the effects of Vitamin C and Lycium barbarum Supplements on the progression of senile cataract in Hong Kong Chinese elderly.
