FAQs for OCULAR PROSTHESIS

  • What is Ocular Prosthesis?
    Ocular Prosthesis is a customized artificial eye that is fitted in place of a natural eye to match with the fellow eye.
  • Why do I need an Ocular Prosthesis?
    Basically there are four reasons to wear ocular prosthesis:
    Comfort.
    Cosmesis.
    Bony Orbital wall, and
    Eyelid development.
    The physical stress caused by eye volume loss and drooping eyelids is relieved by properly fitted ocular prosthesis. Cosmesis is recaptured with a lifelike appearance that is once more acceptable to you. An adequately sized prosthesis is required to maintain near symmetrical bony orbital wall and eyelid development.

FAQs FOR ORTHOPTICS

  • What is orthoptics?
    Orthoptics is the discipline dealing with the diagnosis and treatment of defective eye coordination, binocular vision, and functional amblyopia by non-medical and non-surgical methods, e.g., glasses, prisms, exercises. The goal of orthoptics is to improve comfort and efficiency of binocular function
  • What is accommodation?
    The ability of the eyes to focus clearly on objects at various distances.
  • What is convergence?
    The aiming of the eyes inwards towards an object.
  • What is fusion?
    The process by which what is seen separately, by each eye, is integrated into a single perception.
  • What is stereopsis?
    The ability to perceive relative depth -- due to distance between two eyes-- commonly called 3D vision.
  • What is Amblyopia?
    Amblyopia or lazy eye is a disorder of the eyes. It is characterised by poor or blurry vision that is not correctable with glasses in an eye that is otherwise physically healthy and normal. The problem is due to either no transmission or poor transmission of the visual image to the brain for a sustained period of dysfunction or disuse during early childhood.
FAQs FOR COMPUTER VISION SYNDROME
  • What is computer vision syndrome (CVS)?
    It's a condition, recognized by the American Optometric Association, that affects users of computer monitors and causes eyestrain symptoms, such as blurred vision, dry or burning eyes, delayed focusing, and headaches. It can arise from failure of the eye muscles to work properly.
