PRESBYOND PRK and conventional PRK use similar surface laser techniques, but PRESBYOND adds a blended vision profile for presbyopia. Standard PRK focuses on distance correction only.
Visual aims
Conventional PRK aims for sharp distance in both eyes, leaving near work to reading glasses. PRESBYOND modifies the profile so one eye leans towards distance and the other towards near, with overlap.
- PRESBYOND is targeted at people already noticing reading difficulties
- Standard PRK is better for younger, non-presbyopic patients
- Both preserve corneal strength by avoiding deeper flaps
- Corneal thickness and surface mapping guide suitability
Recovery and day-to-day impact
Surface healing time is similar, but the way vision feels afterwards differs. PRESBYOND offers more freedom at the cost of some complexity.
- Expect several days of discomfort and blurring regardless of profile
- PRESBYOND may bring halos or mild contrast reduction initially
- Standard PRK usually needs reading glasses but offers clean distance optics
- Careful counselling helps you choose based on work, hobbies, and night driving
