3. What is a cataract?
A cataract is the clouding of the normally clear lens of the eye, which prevents light entering the eye from being properly focused on the retina. The lens of our eye clouds naturally as we age, resulting in a gradual reduction of vision.
4. What is glaucoma?
Glaucoma is a progressive condition where the internal pressure in the eye increases, causing damage to fibers in the optic nerve that can result in permanent loss of vision. Glaucoma is a leading cause of blindness and visual impairment today, affecting over two percent of the population over the age of 35. Individuals who are especially at high risk for glaucoma include: individuals with a family history of glaucoma; diabetics and individuals who are very nearsighted or have had a previous eye injury.
5. What is myopia?
Myopia, or nearsightedness, is a common vision condition, or refractive error, that affects nearly 30 percent of the population. A refractive error means that the shape of your eye doesn’t refract the light properly, so the image you see is blurred. Myopia occurs when the curvature of the cornea is too steep or the eyeball is too long, causing light entering the eye to be focused in front of the retina, rather than directly on the retina. Near objects are seen clearly, but objects in the distance appear blurry. For our eyes to be able to see, light rays must be bent or “refracted” so they can focus directly on the retina, the nerve layer that lines the back of the eye. Together, the cornea and the lens refract light rays. The retina receives the picture formed by these light rays and sends the image to the brain through the optic nerve.
6. What is presbyopia?
The word “presbyopia” comes from the Greek and means “elder eye”. Presbyopia is the vision condition where as we age the crystalline lens of the eye loses its flexibility making it difficult to focus up close. After age 40, people begin to experience blurred vision at near points such as when reading or working on a computer. This happens to everyone when they age, even those individuals who have never had a prior vision problem. A common way to address this problem is by wearing bifocal or progressive spectacles. Surgical treatment involves implantation of multifocal lenses. Some patients may be suitable for PresbyLASIK. Dr Khng will be able to assess your suitability for any of thiese procedures.
7. What is astigmatism?
Astigmatism is a common vision condition, or refractive error, that often accompanies myopia (nearsightedness) and hyperopia (farsightedness). A refractive error means that the shape of your eye does not refract the light properly, so that the image you see is blurred. Astigmatism occurs when the curvature of the cornea is irregularly shaped, scattering light rays entering the eye so that they are focused both in front of and behind the retina, rather than directly on the retina. Vision is blurred at all distances. For our eyes to be able to see, light rays must be bent or “refracted” so they can focus directly on the retina, the nerve layer that lines the back of the eye. Together the cornea and the lens refract light rays. The retina receives the picture formed by these light rays and sends the image to the brain through the optic nerve.
8. What is conjunctivitis?
Conjunctivitis is an inflammation of the thin, transparent layer that lines the inner eyelids and covers the white part of the eye. There are three types of conjunctivitis: infectious, allergic and chemical. This condition is normally treated with eyedrops.
9. What is dry eye syndrome ?
Dry eye syndrome is a chronic lack of sufficient tear lubrication to naturally moisten the eye or in some cases, tears may have a chemical composition that causes them to evaporate too quickly. Sometime, this may be caused by medications like antihismatimes and other cold medicines. Rarely, this may be caused by underlying medical problems like autoimmune diseases. Most commonly, aging is the cause. This condition may be treated with tear replacement eyedrops, punctal plugs, or special eyedrops to increase tear production.
10. I don’t know what’s wrong with my eye, I am experiencing vision deterioration. There is pain in my eye. WHAT SHOULD I DO?
You may have something serious going on with your eye, such as acute glaucoma or a corneal ulcer. Seek immediate eye care. If you are experiencing an eye emergency, please contact our office as soon as possible. Go to the next page for contact details.
