NUH ophthalmologist, Dr David Chen shares about the causes and treatment of vision conditions such as presbyopia (lao hua or age-related long-sightedness), myopia (short-sightedness) and hyperopia (long-sightedness). He gives a quick rundown on how our eyes work. In short-sightedness, the light rays converge in the front of the retina with near objects appearing clear but distant objects appearing blurry. In long-sightedness, the light rays converge at the back of the retina where distance objects appear clear but near objects appear blurry. Presbyopia (age-related long-sightedness) usually occurs from around 40 years old for most people. The flexibility of the lens to see near objects is lost as one ages.
LASIK (Laser In Situ Keratomileusis) is a type of laser refractive surgery that reshapes the cornea so that light rays can converge on the retina. This is used to treat short-sightedness and long-sightedness.
Although LASIK is almost synonymous with laser vision correction, it is not the only type of laser refractive surgery available. Other options include PRK (Photorefractive Keratectomy) and SMILE (Small Incision Lenticular Extraction) and ICL (Implantable Collamer Lens) surgery.
