how much and where?
I have a friend who could not pass the pre-lasik examination, is looking to do a ICL, so could you share what you know?
My degree about 500plus.
Doing it at EEC.
I factored in the cost of the follow ups, medicine, surgery, GST, consultation.
I see... yah ICL is more expensive but i didnt know its so much more...
so why did u choose ICL over lasik?

Where got no need to cut? ICL surgery will cut 2-3 small holes right thru cornea into your eyeball. Otherwise how to implant the lens inside?
Advantages are only that (1) the effect is instant and dun need to touch up unless the lens shifts or your degree changes, (2) the corneal surface in front of pupil is not modified, and (3) lens can be changed but will just need another surgery to cut more holes or open the old holes loh...
But strangely, the eye surgeons always avoid mentioning why is it after ICL surgery no sutures are needed to close up the holes made... So I'm always a little curious whether if you poke your eyeball after the surgery, will your eyeball juices ooze out?

self heal? maybe it is like lasik where they close back your cornea and it will heal over time?

But heal by how much and how fast? So fast that no sutures are needed? I highly doubt that...
And besides, lasik flaps do not really heal, maybe because the corneal stroma portion is poor at healing, or maybe because of how the cut is made... I'm not sure. So it is basically a flap thing hanging there, weakly bonded by the fast regenerating epithelium cells, but the structural strength from the Bowman and 0.1mm or so of stroma thickness is sacrificed.
LASIK Flap Dislocation - The Flap Never Heals
LASIK Complications - Notable Quotes
ICL cuts right through all 5 layers of your corneas (top to bottom: epithelium, Bowman's, Stroma, Descemet's, Endothelium), I dunno how well this sort of cut can heal, but I wouldn't want to bet on my vision...
Quote from wikipedia "Unlike the corneal epithelium the cells of the endothelium do not regenerate. Instead, they stretch to compensate for dead cells which reduces the overall cell density of the endothelium and has an impact on fluid regulation"
I picked epi-lasik because it didn't create a flap through my stroma, instead it directly ablates away my corneal stroma, so I have a slightly flatter cornea than other people, but at least the basic structure is more or less still the same. My epithelium can regenerate, so I only lose my Bowman's layer, which serves to help maintain the corneal shape and act as a substrate for epithelium cells to grown on, seems pretty subsidiary to me, hopefully my epithelium compensates by thickening spontaneously
..., in fact some animals naturally dun have Bowman's layer at all.

THis vid for all those who are still under the illusion that bladeless lasik will not cut your corneas... They just use lasers to do it all instead.
The advantage is only that you avoid the risks of hamfisted doctors operating a blade, the disadvantage is that your cornea stroma is still being cut to create the flap

yeah lasik flaps do really heal totally, thats why I was advised not to do diving.
what's the support or link to this saying?
Medical doc show lasik cuts are permanent and do not heal naturally.

Aha, I thought so
Sentence structure certainly seemed rather weird without the "not"

"The wounds in VISIAN ICL surgery are so small that often they do not even require a suture to close them at the end of the surgery."
Probably they didn't close it because the holes do not have a big impact.
ICL is the newer thing, more expensive, but reversible.
Lasik more history and medical record, but permanent.
Patients with unfavourable Lasik conditions (high degree, thin cornea) usually look for ICL.
ICL seem to have been linked to possible future cataracts problem.
Medical insurance to cover operation and future costs also important, does both have in SG?
Success rates should be about the same.
Surgery or infection that can cause permanent blindness, not sure if Lasik has any case, but ICL have a very low chance of infection too.
Starbursts and halos, dry eyes that can ruin your vision also possible in both.

Look at the ICL surgery vid I posted and tell me again the wounds are small. And it is only reversible in that the lens can be removed/replaced. But the wounds made are still there. The question remains, by how much do they heal?
Anyway, I have an idea why they dun suture the wounds in Lasik and ICL. Its because the suture needs attachment points, this would lead to pressure/tension on the cornea, which would cause asymmetry on the corneal surface, thus leading to astigmatism and other effects... I suppose some sort of glue would be better, but glue would need to be biocompatible, long lasting, adhere strongly despite the aqueous environment, and not exert tension or compressive forces when it forms its bonds. Too stringent conditions, thus the doctors delegated the eye's own epithelium cells to do this job

I read that ICL has got lesser risks and is reversible as compared to Lasik...
and because of this, US army is using ICL to reduce the risks involved.
ICL does not result in possible implications like what Lasik does... dry eyes, halos etc.
Anyone here does ICL already?
Hope to hear more from you!
I'm considering either Lasik or ICL?
Wonder if there are any recent medical talks/forums to attend? I'm interested
