Cataract surgery is the process for removing the natural lens of the eye that has developed an opacification and replacing it with an intraocular lens. The opacification, which is referred to as a cataract, is developed due to metabolic changes of the crystalline lens fibers over time. Early symptoms of cataract disease include reduced acuity at low light levels, and strong glare from lights and small light sources at night. The cloudy natural lens of the patient is either removed by the process of phacoemulsification or by extracapsular cataract extraction. In phacoemulsification, either a machine with an ultrasonic handpiece with titanium or steel tip, or a cracker machine is used. Extracapsular cataract extraction involves the technique where the entire lens is taken out while the elastic lens capsule is left intact. This enables the implantation of an artificial lens. An intraocular lens is inserted in the surgery through a small or enlarged incision.

Neutrophils are the most abundant kind of granulocytes and white blood cells in humans. They are an integral part of the innate immune system. Neutrophils are the first inflammatory cells to migrate to a site of injury following trauma. Often they require assistance from other types of immune cells in order to resolve certain infections. The cytokines expressed by activated mast cells, endothelium and macrophages cause neutrophils to congregate at a focus of infection. These neutrophils release cytokines which amplify the inflammatory responses generated by other cells. Through the processes of degranulation, phagocytosis and generation of neutrophil extracellular traps, neutrophils directly attack the invading pathogens. Neutropenia or low neutrophil count makes an individual susceptible to infections. Abnormal neutrophil function leads to excessive tissue damage, disruption of pulmonary barrier, hyperglycemia, etc. This book provides comprehensive insights into the clinical frontiers and functions of neutrophils in health and disease. It will also provide interesting topics for research, which interested readers can take up.

Sickle cell disease (SCD) is a group of inherited blood disorders. Sickle cell anemia (SCA) is the most common form of SCD. It is characterized by an abnormality in hemoglobin found in red blood cells. This results in rigid, sickle-shaped red blood cells. SCA typically develops symptoms like anemia, bacterial infections, stroke, pain, swelling in the hands and feet, etc. The gene defect associated with sickle cell disease is a single nucleotide mutation. Normal red blood cells are elastic thereby allowing cells to deform and pass through capillaries. In SCD, low oxygen tension promotes sickling of red blood cells which fail to return to the normal shape when the ideal oxygen tension is restored. These cells are therefore not able to pass through narrow capillaries, leading to ischemia and vessel occlusion. SCA can lead to complications such as stroke, severe bacterial infections, cholelithiasis, avascular necrosis, osteomyelitis, acute papillary necrosis, etc. This book is compiled in such a manner, that it will provide in-depth knowledge about the concerns and challenges in the management of sickle cell disease.
