Standard PRK mainly corrects distance vision, while PresbyMAX PRK uses a special profile to address both distance and near focus. The choice depends on whether you want freedom from reading glasses as well.
Different visual goals
Conventional PRK aims for sharp distance vision in one or both eyes. PresbyMAX introduces a controlled multifocal effect to extend depth of focus for near tasks.
- PresbyMAX is usually offered to people with presbyopia over about forty
- One or both eyes may be targeted for blended near and distance vision
- Standard PRK may still require reading glasses as you age
- Detailed testing checks dominance, pupil behaviour, and corneal regularity
Adaptation and trade-offs
PresbyMAX requires brain adaptation to new optical patterns. Some people notice mild compromises that standard PRK does not create.
- Halos, glare, or reduced contrast may be more noticeable initially
- Contact lens trials of monovision can help you preview blended vision
- Standard PRK keeps optics simpler but less flexible for close work
- Careful counselling ensures expectations match likely outcomes
