Related articles: Presbyopia Definition Presbyopia is the loss of the crystalline's ability to vary its curvature to focus images placed at different distances. This is not a real disease, but a natural process related to advancing age. With aging, in fact, there is a progressive stiffening of the crystalline lens, which thus loses the power of accommodation and the ability to change shape to allow the correct focusing of nearby objects

Short summary Progressive and irreversible, cataract is an eye disease typical of the elderly, which consists in the gradual opacification of the lens. In simple terms, the cataract is a pathological state in which there is a loss of transparency of the lens. When not surgically treated, the cataract can first cause a slight blurring of the vision which, then, almost always leads to the most absolute blindness
Introduction "How to observe the world under water": this is how many patients suffering from cataracts define their ability to perceive an image, while fixing it carefully. Cataract is an eye disease in which the crystalline lens, the biconvex natural lens that refracts light to focus on an object, undergoes a progressive opacification
Definition of cataract Cataract is defined as a partial or total opacification of the crystalline lens, the natural transparent lens inside the eye that allows to correctly display an object, a figure or any other image. The lens plays a very important role for the eye: similarly to the lens of a camera, this lens placed inside the eyeball has the task of focusing on the retina the light that exceeds the cornea
Introduction Keratitis is a general inflammation of the cornea. Although often infectious in nature, keratitis can also be caused by surgical trauma or favored by the penetration of an object into the eye. Although it may ideally affect anyone, infectious keratitis occurs more often in severely immunocompromised patients (eg those affected by the HIV virus) and weakened; the a traumatic variant of keratitis is instead a typical - albeit not exclusive - condition of contact lens wearers
Definition of Keratitis In medicine the term keratitis identifies a generic inflammation of the cornea, the thin membrane that covers the iris and pupil of the eye. Although the most common keratitis has an infectious origin, the causes of corneal inflammation can also be found in traumas of a different nature
Definition Keratoconjunctivitis is a pathological condition characterized by the simultaneous inflammation of the cornea (keratitis) and conjunctiva (conjunctivitis). There are different sub-categories of keratoconjunctivitis, essentially distinguished on the basis of the causal agent and the symptoms with which they occur
What is that Antibiotic eye drops - together with ophthalmic ointments with antibiotic action - is the main medicine used for the treatment of bacterial eye infections. Of course, the use of antibiotic eye drops must be carried out only on the doctor's instructions and dispensing can only take place upon presentation of a specific recipe
Watch the video X Watch the video on youtube Choice of eye drops The eye drops are undoubtedly the drugs of first choice for the treatment of conjunctivitis, a disorder that is characterized by the inflammation of the conjunctiva. The administration of drugs in the form of eye drops is extremely advantageous because, by directly instilling the active ingredient in the eye, the healing time of the disease is accelerated
