Dysfunctional Lens Syndrome (DLS) part of which is Presbyopia, is a progressive lens disorder that worsens with age and can result in the need to rely on reading glasses to perform near tasks. It encompasses the aging of the crystalline lens, with or without lens opacities, the inability to accommodate due to presbyopia and increased spherical aberrations and/or coma.
Between the ages of 40 to 50 years the lens starts to harden and lose focusing power, near vision starts to deteriorate and development of higher-order aberrations
At 50 to 65 years of age, the loss of near vision or focussing ability, Light scatter and Decreased contrast and night vision
65 Year Olds and above usually would have developed cataracts as the nucleus of the lens yellows, causing reduced vision, affecting color perception
For patients with DLS – Refractive lens exhange is the treatment of choice, with Monovision or Blended Vision being an effective alternative in reducing dependancy on glasses for near tasks such as reading, computer, sewing, reading menu or looking at price tags or lists when shopping.
