Eye surgery is also known as ocular surgery, is surgery performed on the eye or its adnexa, typically by an ophthalmologist. The eye is a fragile organ, and requires extreme care before, during, and after a surgical procedure. An expert eye surgeon is responsible for selecting the appropriate surgical procedure for the patient and for taking the necessary safety precautions. Laser eye surgery and refractive surgery are commonly used. Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye. This is done to correct myopia (short-sightedness), hypermetropia (long sightedness) and astigmatism (uneven curvature of the eye's surface). It is important to note that refractive surgery is not compatible with everyone, and rarely people may find that eye wear is still needed after surgery. A cataract is an opacification or cloudiness of the eyes crystalline lens due to aging, disease or trauma that typically prevents light from forming a clear image on the retina. Canaloplasty is an advanced, nonpenetrating procedure designed to enhance drainage through the eyes natural drainage system to provide sustained reduction of IOP. Canaloplasty utilizes microcatheter technology in a simple and minimally invasive procedure. Oculoplastic surgery or oculoplastics, is the subspecialty of ophthalmology that deals with the reconstruction of the eye and associated structures. Ophthalmic plastic and reconstructive surgery is a specialized area of ophthalmology that deals with the management of deformities and abnormalities of the eyelids, lacrimal (tear) system, orbit (eye socket), and the adjacent face. Refractive surgery aims to correct errors of refraction in the eye, reducing or eliminating the need for corrective lenses.
