PRESBYOND and SMILE offer different solutions for vision correction. PRESBYOND addresses both near and distance vision, while SMILE is mainly for distance correction in people without significant presbyopia.
Technology and indications
PRESBYOND uses excimer laser patterns to create blended vision, often based on LASIK or surface procedures. SMILE employs a femtosecond laser to remove an internal lens of tissue through a tiny incision.
- SMILE is typically used for short-sight and astigmatism without presbyopic design
- PRESBYOND specifically targets age-related near vision loss
- Corneal thickness, curvature, and tear quality influence eligibility
- SMILE may be preferred in younger patients or those at higher dry eye risk
Visual experience and lifestyle
PRESBYOND trades a little optical simplicity for greater spectacle freedom. SMILE maintains simple optics but requires readers as presbyopia appears.
- PRESBYOND may cause halos or different night driving feel, especially early on
- Many enjoy independent near and intermediate vision day to day
- SMILE patients often love the clarity of distance but use readers for close work
- Your eye specialist will help match treatment to age, job, and hobbies
