keratoconus and computer use

We have developed a finite element model of the cornea, that tries to predicts keratoconus-like behavior and its evolution based on material properties of the corneal tissue. Early stage keratoconus is treated by using spectacles or contact lenses. Setting A single-centre study. Soft contact lenses containing spherical or toric corrections are considered as the best option while performing sport activities. METHODS: Corneal material properties were modeled using bibliographic data and corneal topography was based on literature values from a schematic eye model. Keratoconus is an eye condition that affects the cornea, where it thins and reshapes into a cone-like structure causing blurred and distorted vision. What is Keratoconus. How do I do this? It is theorised that by rubbing eyes that are predisposed to keratoconus, you traumatise the cornea. Many individuals with keratoconus (KC) wonder if using a computer will worsen their condition. But I am unaware of any reliable data suggesting that computer use can worsen keratoconus or speed its progression. I have been referred from another hospital for cross-linking. In keratoconus, the shape of the cornea is changed and vision distorted as a result; therefore, it may cause problems with some activities, such as driving a car, using a computer, watching television, and reading. Is this normal? Many cases are relatively minor and you only need glasses to correct them. None … Learn more on +AllAboutVision.com: Computer Eye Strain: 10 … Should I be worried? Maybe your job requires hours of work at a computer. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. Keratoconus is a progressive disease in which the normal cornea becomes more irregular in shape over time resulting in astigmatism, and can progress to a stage where the cornea becomes thinner and begins to bulge into a cone-like shape . In addition, irritated eyes during reading or computer use were reported in 16 per cent of keratoconus participants versus zero per cent of control participants (p = 0.002). Slit-lamp examination. Within the keratoconus group, the amount of blepharitis in participants who reported eye rubbing several times a day and those who reported less eye rubbing was similar (28 per cent versus 22 per cent, p = 0.64). If keratoconus is not treated, it causes serious vision problems. There are several methods that doctors use to diagnose keratoconus. Prev; Next; Comments # Ani 2015-10-26 12:46. This causes a distortion in vision that often cannot be corrected with glasses. Keratoconus is a progressive eye disease which affects your cornea, the clear window at the front of your eye. In this condition, the front part of your eye, called the cornea, thins out and gets weaker over time. It could be as easy as having the patient look downwards and having the doctor carefully view the contour of the cornea as it interfaces with the lower eyelid. My vision is sometimes better on one day than it is the next. In a slit-lamp examination, your eye doctor will shine a vertical beam of light on your eye and use a low-power microscope to examine the cornea's shape. Conditions such as keratoconus (affects the front of the eye, where the cornea grows into the shape of a cone) are on the rise. Computer Eyewear; Safety Eyewear; Sunglasses; Keratoconus . I would like to bring my appointment forward. Therefore it is very important to have strategies to decrease the urge to rub. Meanwhile, the following are four ways to cope with vision loss and other keratoconus symptoms in the college environment. This causes it to become thinner and distorted in shape. A: Extensive computer use can decrease blink rate and lead to dysfunction of the meibomian glands and subsequent dry eye. If you (or your college-age offspring) has keratoconus, speaking with a professional at the Precision Keratoconus Center can help you to understand keratoconus treatment options. Corneal crosslinking is a procedure that strengthens the thin and weakened cornea in keratoconus. Whatever the reason, your body is probably feeling the effects of spending too much time staring at a computer monitor, which could result in Computer Vision Syndrome (CVS). ABSTRACT: Using a computer-assisted videokeratoscope, we determined the topographic findings of 14 eyes of 10 patients with keratoconus. The role of the cornea is to direct light onto the retina at the back of your eye to allow you to see clearly. Since the cornea is the primary focusing lens of the eye, any distortions in it lead to a distorted image projected onto the retina. Figure: Computer-generated topographic map of the right eye of a 26year-old male with a family history of keratoconus with recent onset of spectacle blur. It involves the use of riboflavin (vitamin B) eye drops, in combination with ultraviolet light. This affects how it focuses light onto your retina, at the back of your eye.
