Quality of Life and Uncorrected Binocular Visual Acuity (UBVA) Evaluation in Patients Undergoing Cataract Surgery Using 4 Different Types of Lens Implant Combinations: a Multicenter, Prospective, Comparative and Randomized Study

The most common surgical procedure in France is cataract surgery by ultrasonic phacoemulsification. This is a presbyopia compensation scheme that aims to cause a slight blurring of one eye for near vision in one eye, but the other eye being intended for distance vision. Patients are often still active on a medical basis, so choosing the intraocular implant to use is a difficult challenge. In addition, there is also a lack of scientific evidence surrounding implants, during a surgical treatment of cataract lenses by phakoexeresis, for otherwise healthy eyes and in a situation where patients no longer wear glasses postoperatively. Different studies have emerged comparing the simultaneous implantation of various types of multifocal implants with each other, but no research has been conducted into mixed batches of mix - match'" implants.

Comparison of Treatment With Preservative-free Dexamethasone 0.1% (Monofree Dexamethason) and Diclofenac 0.1% (Dicloabak) Eye Drops Versus Preserved Dexamethasone 0.1% (Maxidex) and Diclofenac 0.1% (Voltaren Ophtha) Eye Drops After Cataract Surgery

According to Daien et al. , the incidence of cataract surgery in France in 2012 was 11/1000 person-years. Benzalkonium chloride is the most common eye drop preservative and is associated with a variety of ocular adverse effects, including dry eye and ocular surface inflammation. Moreover, anterior chamber inflammation was found in two clinical trials comparing the effects of BAK-containing and preservative-free eye drops, despite a year of exposure to BAK. BAK may also play a role in macular edema formation, according to some reviews. Preservative-free eye drops have been produced in the last decade, providing preservative-free alternatives for nearly all the eye medications due to the well-established adverse effects of preservatives. The aim of this research is to see whether omitting preservatives from the postoperative topical care of cataract surgery can reduce symptoms and signs of ocular surface disease, intra-ocular inflammation, and the risk of cystoid macular edema. In addition, ocular microbiome research has been included in our study due to its known correlation with the ocular immune system. Although the ocular surface is continuously colonized by a commensal microbial species, the healthy ocular surface is not in an inflammatory state. Our expert in the field of ocular microbiome research is affiliated with the University of Ghent's department of biochemistry and microbiology.
