Presbyopia Correction

An advanced method of laser vision correction used for treating patients with age-related loss of near vision, also known as presbyopia. In Auckland, it is available exclusively at Auckland Eye.

Presbyopia is often referred to as 'the ageing eye condition' because it is a disorder that affects everyone during the natural ageing process. Presbyopia results in the inability to focus up close, a problem associated with refraction in the eye. Most people begin to notice the gradual effects of presbyopia sometime after age 40.

Presbyopia symptoms include:

  • A tendency to hold reading material further away to make the letters clearer
  • Blurred vision at normal reading distance
  • Eye strain or headaches after reading or doing close up work

What Causes Presbyopia?

With young eyes, the lens of the eye is soft and flexible, allowing the tiny muscles inside the eye to easily reshape the lens to focus on close and distant objects.

However, during the ageing process, the natural lens inside our eyes begins to gradually harden and become less flexible. As a result, the lens can’t change shape as easily and it is unable to bend light properly in order to focus it on the retina.

The ageing process also affects the muscle fibres around the lens making it harder for the eye to focus. The ineffective lens causes light to focus behind the retina, resulting in blurred vision when looking at objects up close.

Presbyopia Correction

Although presbyopia is an unavoidable age-related condition, fortunately, it can be easily diagnosed through a routine eye exam and there are various treatment options available to help restore near vision.

Non-surgical treatment options include eyeglasses and contact lenses. However, due to the fact that both eyeglasses and contact lens require ongoing maintenance, they are usually a temporary solution for patients with presbyopia. As a result, with the recent developments in ophthalmology, people are now opting for more permanent solutions through refractive (focus correcting) surgery for presbyopia.

PRESBYOND® Laser Blended Vision

PRESBYOND® Laser Blended Vision from Carl Zeiss transcends conventional monovision methods by offering clear sight at all distances: near, intermediate, and far. Better yet, virtually all patients will no longer require reading glasses.

PRESBYOND® Laser Blended Vision represents the next stage in eye care excellence. Similar to conventional monovision, the dominant eye is corrected for distance vision to almost plano (i.e. no refractive error, or what can be referred to as normal vision), whereas the non-dominant eye is corrected to be slightly myopic (i.e. nearsighted, or when distant images are blurred).

This micro-monovision strategy is then enhanced further by increasing the depth of field of each eye using a wavefront-optimised ablation profile to create a continuous refractive power gradient for the whole optical zone of the cornea. PRESBYOND® Laser Blended Vision is an absolutely individualised treatment plan based on the patients eye function. As a result, a customised fusion of the two images for near and distance vision is created for each patient – the so called Blend Zone.
