Anterior chamber metal fragments after phacoemulsification surgery

Journal of Cataract and Refractive Surgery
P L Davis, D Mastel

Abstract

To determine whether metal fragments can be shaken loose from phaco needles during surgery and embed in the iris. Private practice, Vernon, British Columbia, Canada, and scanning electron microscope laboratory, Mastel Precision, Rapid City, South Dakota, USA. The surfaces and rims of new and used phaco needles and the lumens of halved new needles were examined by scanning electron microscopy (SEM). To determine whether the fragments on the phaco needles were approximately the same size as those seen in the iris, a photograph of an eye with metal fragments imbedded in the iris was projected and the image size of the metal fragments approximated by using their magnification value. The magnification scale of the SEM images was used to determine the size of the metal fragments photographed on the phaco needles. The SEM studies of new phaco needles revealed tiny fragments of metal firmly adherent to the interior, exterior, and rim surfaces. No fragments were detected on the surfaces of the used phaco needles. Two metal fragments in the eye photograph were calculated to be 0.20 x 0.20 mm and 0.15 x 0.20 mm. Those in the SEM photos were calculated to be 0.03 to 0.10 mm. Althogh SEM of new titanium phaco needles revealed adherent metal...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
