PRK and PRESBYOND PRK both reshape the cornea, but PRESBYOND is tailored for people with presbyopia who want clearer near and intermediate vision. Understanding the differences helps you choose the most suitable correction.
Standard distance PRK
Traditional PRK targets clear distance vision in both eyes. It does not directly treat the age-related loss of near focus, so reading glasses are still likely later on.
- Simpler optical profile and easier adaptation for most patients
- Best suited to younger people without significant presbyopia
- Near vision can be supported by glasses or contact lenses
- Long-term stability is usually excellent when eyes are well selected
PRESBYOND blended vision
PRESBYOND uses a more complex laser pattern to extend focus range. One eye leans towards distance and the other slightly towards near, with overlap in the middle.
- Reduces dependence on reading glasses for many everyday tasks
- May cause temporary night-time glare or reduced contrast
- Some people still choose glasses for fine print or prolonged tasks
- Thorough assessment ensures your brain can adapt to blended vision
