Rollercoasters after ICL surgery — is it actually risky long-term?

Hi all,

I had ICL (implantable collamer lens) surgery in November last year. My vision is great now and my recovery was smooth.

When I asked my surgeon about high-adrenaline activities, he said I should avoid bungee jumping permanently because of the forces on the eye, and that rollercoasters might also be best avoided. His reasoning was that there have been some cases where rides caused lens dislocations or other eye problems.

Here’s where I need your input:

  • Has anyone here ridden rollercoasters after ICL surgery — months or years later?

  • Any documented cases of ICL dislocation from a rollercoaster?

  • Are mild/family coasters likely to be fine, with the risk mainly from high-G rides with sudden jerks/rotations?

  • What’s the actual long-term risk once healing is complete? Is it a “1 in a million” scenario or something more?

  • From an ophthalmologist’s perspective, is this about sustained G-forces or the sudden whiplash-type motion (like bungee rebound or violent launches)?

I’m going to Fuji-Q Highland in Japan, which has some of the most intense coasters in the world (Takabisha, Eejanaika, Do-Dodonpa). I’m trying to decide if I should avoid those entirely and just stick to the gentler rides — or if, 9 months post-op, the risk is negligible.

Any ophthalmologists, optometrists, or fellow ICL patients who’ve been in this situation — I’d love to hear your advice or experiences.

Thanks!
