However, in rare cases severe complications can occur shortly after the intervention. Therefore, patients are advised to undergo an ophthalmological examination postoperatively, which should be performed as soon as possible in case of emergencies.

Attaining optimal flange size with 5-0 and 6-0 polypropylene sutures for scleral fixation.

A technique for achieving an optimal flange size with 5-0 polypropylene and 6-0 polypropylene used for flanged intrascleral intraocular lens fixation is described. Flange size in polypropylene sutures is dependent on heating length and independent of forceps grip during heating. It was identified that heating of 1 mm created the optimal flange size for a 5-0 polypropylene suture when used for a 27-gauge needle scleral tunnel and for a 6-0 polypropylene suture when used for a 30-gauge needle scleral tunnel.

The human lens: An antioxidant-dependent tissue revealed by the role of caffeine.

Cataract is the leading cause of blindness worldwide and surgery is the only option to treat the disease. Although the surgery is considered to be relatively safe, complications may occur in a subset of patients and access to ophthalmic care may be limited. Due to a growing and ageing population, an increase in cataract prevalence is expected and its management will become a socioeconomic challenge.

Methods: This prospective randomized trial was designed as a pilot study with two groups: ILM peeling with ILM flap transposition over the macular hole vs. classic ILM peeling.

Comparison of methods to experimentally induce opacification and elasticity change in ex vivo porcine lenses.

At the moment, cataract, which is the opacification of the eye's lens, can only be treated by surgery. In order to develop and test new pharmacological treatment strategies for the disease, there is a need for an appropriate in vitro model using ex vivo animal lenses. In this study, porcine lenses were incubated in either culture medium, glucose, triamcinolone acetonide, sodium chloride, hydrogen peroxide, sodium selenite, neutral buffered formalin, or were exposed to microwave heating to experimentally induce lens opacification.
