ICL (implantable lens) corrects vision by placing a lens inside the eye.
If you've been told laser surgery is difficult because your cornea is thin or your myopia is severe, ask about ICL, which places a lens inside the eye without reshaping the cornea.
ICL corrects vision by placing a lens behind the iris without removing corneal tissue. It can correct extreme myopia, astigmatism and hyperopia in one procedure.
The lens's 7 holes support the flow of fluid inside the eye, and its thin center and conical aspheric design keep light loss below 10%.
Diagnostic · Corneal endotheliumTOPCON SP-1PWith the TOPCON SP-1P, which images corneal endothelial cells at high magnification, and the Pentacam, which analyzes the front of the eye, we check the space for the lens and the condition of the cornea.

and after the exam, we recommend only the surgery you need.
ICL corrects vision by placing a lens inside the eye. Because the cornea is not reshaped, people with thin corneas or high myopia who are not suited to laser can also consult us.
A posterior chamber lens placed behind the iris. A wide optic that accounts for the flow of aqueous humor, a thin profile and a conical aspheric design keep light loss under 10%.
Seven holes in the lens help aqueous humor flow smoothly inside the eye.
A thinner center reduces light scattering.
Can correct extreme myopia, astigmatism and hyperopia in one procedure.
Made of a low-irritation material compatible with eye tissue.
A small incision of about 3mm is made at the edge of the cornea.
The ECHO lens is inserted through the incision.
The lens is positioned behind the iris.
ICL places a lens inside the eye without reshaping the cornea. That's why it's considered by people whose corneas aren't thick enough, or whose high or extreme myopia makes other vision correction difficult.
Even with the same prescription, the space inside the eye differs from person to person. So we check the inside of the eye before choosing the lens type and size. If you wear contact lenses, you may need to stop before the exam—please check when booking.
We check whether there's enough space between the cornea and iris for the lens.
We check the number and shape of the inner cells that keep the cornea clear.
We check the pressure inside the eye before surgery.
High myopia often comes with a longer eyeball, so we examine the retina carefully.
We set the power and range to correct.
We choose a lens size and shape that fit the space inside your eye.
Analyzes corneal topography, thickness and shape to detect abnormal corneas such as keratoconus before surgery.
Captures 200° wide-field images out to the peripheral retina without dilating drops, for early detection of macular degeneration, diabetic retinopathy and retinal detachment.
Photographs the inner corneal cells at high magnification to check for signs of trauma, corneal edema and corneal dystrophy.
Measures eye pressure without touching the eye. Used for early glaucoma diagnosis and follow-up.
Based on the US FDA's patient information for phakic intraocular lenses (ICL). You'll receive your own schedule at your visit.
Eye drops or ointment are applied and an eye shield is placed. You may be sensitive to light or feel as if something is in your eye.
We check your progress and explain how to use your eye drops. Drops that reduce inflammation and infection are used for a few weeks.
Vision may be hazy or blurry. Don't rub your eyes, especially for the first 3–5 days.
Vision may fluctuate and usually stabilizes around this time.
This is when the eye heals. Keep water out of your eyes until you're told otherwise, and avoid bending over to pick things up, lifting heavy objects and strenuous exercise.
Regular check-ups monitor the lens and your corneal endothelial cell count. Protect your eyes from UV when outdoors, and rest them after long screen time.
Placing a lens inside the eye carries risks. Below is what the US FDA tells ICL patients.
Pressure inside the eye may rise after surgery and need medication or further treatment.
If corneal endothelial cells decrease too much, the cornea can become cloudy, so we check the cell count regularly.
A cataract, where the natural lens becomes cloudy, can develop.
The risk may increase after surgery inside the eye. If you see flashes, floaters or a blocked part of your vision, get seen right away.
Glare, halos or double vision may occur in dim light.
If the power or size isn't right, additional surgery to reposition, replace or remove the lens may be needed.

No. A small incision of about 3mm is made at the edge of the cornea, and the ECHO lens is placed to sit behind the iris. No corneal tissue is removed.
People whose corneas are thin or whose myopia is severe enough to rule out laser can also consult us. But whether it's possible depends on checking the space for the lens (anterior chamber depth), corneal endothelial cell count, eye pressure and retinal health.
ECHO ICL is designed to correct extreme myopia, astigmatism and hyperopia in one procedure. The actual correction range is determined by your exam results.
The 7 holes in the lens help fluid inside the eye flow smoothly. Its thinner center also reduces glare.
Because there's a lens inside your eye, the lens, eye pressure and corneal endothelial cell count need ongoing monitoring. If you notice flashes, floaters or a blocked part of your vision, say that you've had ICL and get seen right away.
If needed, surgery can reposition, replace or remove the lens. If you later have cataract surgery, the lens is removed at the same time. Each additional surgery carries its own risks (US FDA).
Our director reviews your results and explains them in person.
