Posterior Capsule Opacification (PCO) is the commonest complication of cataract surgery occurring in up to 50% of patients by 2 to 3 years after the operation [1]. This paper proposes a new approach for the assessment of PCO digital images. The approach deploys an unsupervised learning technique for clustering image pixels into different regions based on chromatic attributes. The innovation asp...
Posterior capsular opacification (PCO) is the major complication arising after cataract treatment. PCO occurs when the lens epithelial cells remaining following surgery (LCs) undergo a wound healing response producing a mixture of α-smooth muscle actin (α-SMA)-expressing myofibroblasts and lens fibre cells, which impair vision. Prior investigations have proposed that integrins play a central ro...
Purpose Numerous pharmacologic substances have been proposed for preventing posterior capsule opacification (PCO). The following trial was to compare those drugs to find more suitable options. IOL should then be modified by the pharmaceuticals as a drug-delivery device. Methods A systematic literature search was performed to identify published substances. FHL-124 was used to determine cell pr...
in a fellow-eye-controlled trial, we compared the posterior capsule opacification (pco) rates of single-piece (sa60at) and three-piece (ma60ac) hydrophobic acrylic intraocular lenses (iol) in 54 pair-matched eyes of 27 age-related cataract patients who consecutively underwent bilateral (4-8 weeks apart) phacoemulsification horizontal chopping performed through a capsulorrhexis of approximately ...
BACKGROUND Complete removal of the cortex has been advocated to prevent posterior capsular opacification but carries the risk of zonular dehiscence, hence there is a need for a safe maximal cortical cleanup technique in eyes with severe diffuse zonulopathy in subjects above age 90. METHODS We used bimanual central cortical cleaning by elevating central fibers and aspirating them toward the pe...
