The lens is a biological structure that is surrounded by the capsule. It consists of epithelial cells that are responsible for the growth and development of the entire ocular lens (Andley, 2008).The tissue of the lens has the ability to grow throughout the life cycle however, the pattern of growth in the embryo is greater than it is in adults. Additionally, cell division in the human lens occurs only in limited lens cells (Andley, 2008). The addition of new cells to the outside of the lens causes the lens growth however, the lens nucleus cells do not change since birth ( Hughes, et al., 2015). Therefore, any damaged lens cells are not replaced.
The lens cells could be damaged due to environmental factors such as exposure to radiation, aging (presbyopia), diseases (Aphakia, Ectopia lentis, Lens regeneration, etc), chemical exposure, etc.
This results in decreasing the light transmission and focusing into the retina even in the normal aged lens. The damaged lens could be replaced surgically, however, this can cause abnormal growth of the leftover cells that might cause the replacement to be incompetent.
I am an enthusiastic BSC pharmacology graduate with research experience in the microbiology pharmacology field. I graduated from Kingston university with first class bachelor's degree with honours in pharmacology. Through study and practical experience, I gained an understanding of the regulatory framework and an ability to organize work effectively, pay attention to details and communicate clearly and concisely. I aim to develop my career into microbiology through postgraduate study and to build on my current knowledge in a clinical trials administration role.
