LASIK, PRK and SMILE: both eyes, same day
Laser refractive procedures are almost universally done bilaterally in one session. The procedures are extraocular, infection risk is very low, and the recovery is symmetrical. Doing one eye at a time leaves you with a large imbalance between eyes for days or weeks, which is harder to function with than a brief period of blurry vision in both. Expect both eyes done in a single 20 to 30 minute appointment.
Exception: PRK in patients who cannot afford a week of blurry vision, such as sole caregivers, is occasionally staged so one eye stays sharp.
ICL: usually same day, sometimes staged
The ICL is intraocular surgery, and the concern with doing both eyes on the same day is the small risk of bilateral endophthalmitis, a sight-threatening infection. Modern practice mitigates this with separate sterile setups, separate instrument trays and separate lots of viscoelastic for each eye, treating them as two operations. With those precautions, most Colombian and European surgeons do both eyes the same day. Some prefer a two to seven day gap, particularly for very high prescriptions or when they want to confirm the first eye's vault before sizing the second. Neither approach is wrong; ask which yours uses and why.
Refractive lens exchange and cataract surgery: staged by tradition
RLE and cataract surgery have historically been done one eye at a time, often a week apart, for two reasons: bilateral infection risk, and the chance to refine the second eye's lens calculation based on the first eye's outcome. Immediate sequential bilateral surgery is now practised in some centers with the same sterility rules used for ICL, and it is more common for RLE than for cataract because RLE patients are younger and healthier. In Colombia both models exist; the staged model is more common. This is the procedure where trip length matters most.
| Procedure | Typical approach | Nights in Colombia |
|---|---|---|
| LASIK / PRK / SMILE | Both eyes, same day | 4 to 6 |
| EVO ICL | Same day or 2-7 day gap | 7 to 10 |
| RLE / cataract | Usually 3-7 days apart | 8 to 12 |
What staging means for you
- Between eyes you will have one corrected eye and one uncorrected eye. If your prescription is strong, glasses will not work (one lens would be plain) and you may need a contact lens in the untreated eye for a few days.
- Budget the extra nights. Two extra nights in Medellín is cheap; a second international flight is not.
- Ask that the second-eye date is set before you buy your return flight.

Frequently asked questions
Is it safer to do one eye at a time?
For laser procedures, no meaningful difference. For intraocular procedures, staging slightly reduces the already tiny risk of bilateral infection, at the cost of an extra visit.
Can I ask for both eyes the same day for RLE?
You can ask. Many Colombian surgeons will agree for healthy younger RLE patients if they use strict separate-eye sterility protocols.
How long between eyes for cataract surgery?
Commonly one to two weeks locally; for travelling patients most surgeons compress this to three to seven days.
