Objective Measurements of Lens Opacification After Intravitreal Injections

2019-06-02 23:09:17 | BioPortfolio


The main hypothesis is the opacification of the lens would be increase by the IVT.

The opacification of the lens can be objectived by :

- the objective scatter index (OSI) on the OQAS device

- the average lens density (ALD) on the IOLMaster device.

Eligible patients will be followed at least 12 months after in intravitreal injection and the opacification of their lens is regularly controlled with OSI and ALD.

The objective is to study the dynamics of lens opacification in IVT-treated eyes evaluated by OSI for at least 1 year.

Medical and Biotech [MESH] Definitions

Clouding or loss of transparency of the posterior lens capsule, usually following CATARACT extraction.

Procedures performed to remove CAPSULE OPACIFICATION that develops on the POSTERIOR CAPSULE OF THE LENS following removal of a primary CATARACT.

Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.

The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.

Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.
