Presbyopia — the natural, age-related decline in near-vision focusing ability that affects nearly everyone by their mid-40s to 50s — adds a genuine complication to standard refractive surgery planning that's worth understanding clearly.
Why presbyopia complicates standard LASIK
Standard LASIK corrects distance vision — it doesn't address the separate, age-related decline in near-focusing ability. A patient over 40 who gets standard LASIK to fully correct distance vision will often still need reading glasses afterward, which surprises some patients who assumed LASIK would eliminate all corrective eyewear.
Full distance correction and complete reading-glasses independence aren't automatically the same outcome for patients over roughly 40–45. This is worth discussing explicitly in your consultation rather than discovering as a surprise after surgery.
Monovision as an option
One approach: correcting one eye for distance vision and the other slightly for near vision, allowing your brain to naturally favor each eye for its respective task. This isn't right for everyone — some patients adapt well, others find the vision difference between eyes uncomfortable, which is worth testing with a contact lens trial before committing surgically.
Other approaches worth discussing
- Correcting both eyes fully for distance and accepting reading glasses for near tasks — a completely reasonable choice many patients make
- Blended vision approaches, a less extreme version of monovision
- Discussing timing — some patients prefer to wait and address presbyopia separately with a future procedure once it's more fully progressed
What to bring to this conversation
Be explicit with your surgeon about your priorities — how much you value distance vision independence vs. near vision independence — since this genuinely shapes which approach is recommended, more than a generic "best" answer exists for every patient over 40.
