Visian ICL Procedure – What to Expect
Understanding the Visian ICL (Implantable Collamer Lens)
The Visian ICL is a tiny, flexible lens made from a material called Collamer, which contains collagen. Our eye doctor places the lens through a small incision and positions it behind your iris, the colored part of your eye. The ICL works with your natural lens to focus light correctly on your retina, improving your vision without permanently changing the shape of your cornea.
Because the lens sits inside your eye, it is invisible to you and to others. The Collamer material is designed to work naturally with your eye and does not cause your body to reject it.
You may be a good candidate if you have moderate to high nearsightedness, with or without astigmatism, and your prescription has been stable for at least one year. The procedure is approved for adults between 21 and 45 years of age, though we may recommend it outside this range in specific cases. You should have healthy eyes with no history of glaucoma, cataracts, or certain other eye conditions.
- Stable prescription for at least 12 months
- Adequate space inside the eye for the lens
- Healthy corneas and retinas
- No active eye inflammation or infection
- Not pregnant or nursing
Certain eye conditions make Visian ICL unsafe or less effective. If you have glaucoma or uncontrolled eye pressure, the ICL can block fluid drainage inside your eye and worsen the problem. People with a shallow anterior chamber do not have enough room for the lens, and those with unstable prescriptions may not get lasting results.
We also do not recommend the procedure if you have had uveitis or iritis, have cataracts, or are pregnant or breastfeeding. During your consultation, our eye doctor will measure your eye structures and review your medical history to make sure this procedure is right for you.
One of the biggest advantages of the Visian ICL is that it can correct higher levels of nearsightedness than laser vision correction. The lens is removable, so if your vision changes or you develop cataracts later in life, we can take it out. Many patients notice sharper night vision and less glare compared to some laser procedures.
However, the ICL does not correct presbyopia, the age-related loss of near vision that typically begins in your 40s. You may still need reading glasses as you get older. There is also a small risk of complications such as increased eye pressure, cataract formation, or infection, which we will monitor closely during your follow-up visits.
Preparing for Your Visian ICL Procedure
Before scheduling your procedure, you will have a thorough eye exam that includes checking your vision, measuring your eye pressure, and examining the health of your cornea, lens, and retina. Our eye doctor will also test your tear film to make sure you do not have significant dry eye, which can affect healing. This exam helps us determine whether the ICL is safe and appropriate for your eyes.
We will also discuss your medical history, including any medications you take and any past eye surgeries or injuries. Be sure to tell us if you have diabetes, autoimmune diseases, or a family history of eye conditions, as these factors can influence your treatment plan.
Accurate measurements are critical for selecting the right lens size and power. We use specialized imaging to measure the length of your eye, the depth of your anterior chamber, and the curvature of your cornea. These measurements ensure the ICL fits properly and provides the best possible vision correction.
- Corneal topography to map the shape of your cornea
- Optical biometry to measure eye length and chamber depth
- Pupil size measurement in different lighting conditions
- Refraction to determine your exact prescription
Contact lenses can temporarily change the shape of your cornea, which can affect the accuracy of your measurements. We may recommend stopping soft contact lenses for at least one week before your pre-operative measurements. If you wear rigid gas permeable lenses, you may need to stop wearing them for three weeks or longer.
Your corneas need time to return to their natural shape so we can get the most precise readings. Our eye doctor will give you specific instructions based on the type of lenses you wear and how long you have been wearing them.
You will not be able to drive yourself home after the procedure because your vision will be blurry and you will have received sedation. Arrange for a responsible adult to drive you to and from the surgery center and stay with you for the first few hours at home. Plan to take at least one or two days off work to rest and start your recovery.
Prepare your home by setting up a comfortable place to rest with extra pillows, and have your prescribed eye drops ready. Avoid wearing makeup, lotions, or perfumes on the day of surgery, and wear comfortable clothing.
In the days before surgery, we may prescribe antibiotic eye drops to reduce the risk of infection. You may also receive anti-inflammatory drops to use before and after the procedure. Follow the dosing schedule carefully and wash your hands before applying any drops.
- Antibiotic drops to prevent infection
- Anti-inflammatory drops to reduce swelling
- Dilating drops on the day of surgery
- Any oral medications as directed by our eye doctor
What Happens During the Visian ICL Procedure
On the day of your procedure, arrive at the scheduled time so the staff can check you in and prepare you for surgery. You will change into a surgical gown and have your vital signs checked. The team will review your medical history one more time and answer any last-minute questions you may have.
A nurse will place numbing drops in your eyes and may give you a mild sedative to help you relax. You will be awake during the procedure, but you should feel calm and comfortable.
We use topical anesthetic eye drops to numb the surface of your eyes, so you will not feel pain during the procedure. The drops work quickly and last throughout the surgery. You may also receive a light oral sedative or intravenous medication to help you stay relaxed.
Your eye will be held open gently with a small instrument called a lid speculum, so you will not need to worry about blinking. Our eye doctor will make sure you are completely comfortable before beginning.
Our eye doctor creates a tiny incision, usually less than three millimeters, at the edge of your cornea. The ICL is folded and inserted through this small opening using a special injector. Once inside your eye, the lens gently unfolds and our eye doctor carefully positions it behind your iris and in front of your natural lens.
The lens has small holes that allow fluid to flow naturally inside your eye. After positioning the ICL, our eye doctor checks that it is centered and stable. The incision is so small that it typically seals on its own without stitches.
The actual procedure usually takes about 20 to 30 minutes per eye. If you are having both eyes treated on the same day, the total time in the operating room will be longer. Most of the time in the surgery center is spent preparing you and letting the numbing drops take effect.
After the procedure, you will rest in a recovery area for a short time while the staff monitors your eye pressure and comfort level. You can usually go home within an hour or two.
You should not feel pain during the procedure, though you may notice pressure or mild sensations as our eye doctor works. Your vision will be blurry during surgery because of the bright lights and the drops in your eyes. You may see shapes, colors, or movements, but you will not see the instruments clearly.
Some patients feel anxious even with sedation, and that is normal. Our eye doctor and the surgical team will talk to you throughout the procedure to keep you informed and reassured.
Recovering After Visian ICL Surgery
Your vision may be blurry or hazy right after the procedure, and your eyes might feel scratchy or watery. These sensations are normal and usually improve within the first day. You may also notice glare or halos around lights, especially at night, which should decrease as your eyes heal.
- Rest with your eyes closed as much as possible
- Use your prescribed eye drops on schedule
- Wear the protective eye shield while sleeping
- Avoid rubbing or touching your eyes
- Do not get water or soap in your eyes
Most patients notice significant vision improvement within the first few days, though your vision may continue to fluctuate slightly as your eyes adjust to the new lens. You might see better at some distances than others initially, and this usually evens out over the first few weeks. Some people experience mild light sensitivity or dryness during this period.
If your vision seems worse than before surgery, or if you notice sudden changes, contact our office right away. Gradual improvement is expected, but sharp declines or new symptoms need immediate evaluation.
You will need to use antibiotic and anti-inflammatory eye drops several times a day for at least a week, and possibly longer depending on how your eyes heal. Wash your hands thoroughly before using any drops. Tilt your head back, pull down your lower eyelid gently, and place one drop inside without letting the bottle tip touch your eye or eyelashes.
If you need to use more than one type of drop, wait at least five minutes between each medication. Set reminders on your phone to help you remember the schedule, because consistent use is important for preventing infection and reducing inflammation.
For the first week after surgery, avoid strenuous exercise, heavy lifting, swimming, and hot tubs. These activities can increase eye pressure or introduce bacteria that could cause infection. You can watch television, use a computer, and read as long as your eyes feel comfortable, but take breaks if you notice strain or dryness.
- No swimming or hot tubs for at least two weeks
- Avoid rubbing your eyes for several weeks
- No contact sports or activities with risk of eye injury for one month
- Wear sunglasses outdoors to protect from bright light and dust
Many patients return to desk work or light activities within one to three days, depending on how quickly their vision clears and how comfortable their eyes feel. If your job involves physical labor, exposure to dust or chemicals, or requires very precise vision, you may need to wait a week or more. Our eye doctor will give you personalized guidance based on your occupation and recovery progress.
You can resume driving once your vision meets legal requirements and our eye doctor clears you, which is often within a few days. Always bring a driver to your first follow-up visit, as we may dilate your pupils and blur your vision temporarily.
Follow-Up Care and Monitoring
We will see you for a follow-up visit within the first day or two after surgery to check your eye pressure, confirm the ICL is positioned correctly, and assess your healing. Additional visits are typically scheduled at one week, one month, three months, six months, and one year after the procedure. These appointments allow us to monitor your vision and catch any potential issues early.
Even if your eyes feel fine, it is essential to attend all scheduled visits. Some complications, such as gradual increases in eye pressure, may not cause symptoms until they become serious.
At every follow-up appointment, we measure your eye pressure to make sure the ICL is not blocking fluid drainage. We also test your vision to see how well you are seeing at different distances and check the position of the lens inside your eye. Using a special microscope, our eye doctor examines the health of your cornea, the area around the ICL, and your natural lens.
- Eye pressure measurement
- Visual acuity testing at near and far distances
- Slit lamp examination of the ICL position
- Assessment of corneal clarity and health
- Evaluation of the natural lens for early cataract changes
Once your eyes have fully healed, you should continue to have annual comprehensive eye exams to monitor the ICL and your overall eye health. The lens is designed to stay in place permanently, but we will check for any shifts in position or changes in your eye structures. You should also maintain good general health, as conditions like diabetes can affect your eyes over time.
Protect your eyes from injury by wearing safety glasses during sports or work activities that pose a risk. If you develop new symptoms such as flashes of light, floaters, or pain, contact our office promptly even if your next scheduled visit is months away.
Although serious complications are rare, you should seek immediate care if you experience sudden vision loss, severe eye pain, intense redness, or a sudden increase in floaters or flashes of light. These symptoms could indicate increased eye pressure, infection, retinal detachment, or lens displacement. Rapid treatment is essential to prevent permanent damage.
- Sudden decrease in vision or loss of vision
- Severe or worsening eye pain not relieved by over-the-counter pain medication
- Intense redness or discharge from the eye
- New or worsening flashes of light or shower of floaters
- Seeing halos or rainbows that worsen over time
Frequently Asked Questions
Most patients achieve excellent distance vision without glasses after the procedure, though you may still need reading glasses once you reach your 40s because the ICL does not correct presbyopia. Some people also choose to wear glasses for specific tasks like computer work or night driving if they want even sharper vision, but this is usually optional rather than necessary.
Yes, one of the key advantages of the Visian ICL is that it can be removed or replaced if your vision changes significantly or if you develop cataracts later in life. The removal procedure is similar to the original implantation, and most patients who have their ICL removed do not experience lasting effects on their eye structure.
The Visian ICL is designed to remain in your eye indefinitely and does not have an expiration date. Clinical studies show that the lens remains stable and effective for decades. However, your natural vision can still change over time due to aging, and you may eventually need cataract surgery or other treatments unrelated to the ICL itself.
Serious complications are uncommon but can include infection, increased eye pressure that may lead to glaucoma, cataract formation if the ICL touches your natural lens, or retinal detachment. There is also a small risk of the lens rotating or moving out of position, which may require a second procedure to reposition or replace it. Our eye doctor will discuss your individual risk factors during your consultation.
If your vision changes after ICL implantation, you may be able to have LASIK or PRK to fine-tune your prescription, though this is rarely necessary. When you eventually need cataract surgery, the ICL can be removed during the same procedure, and an intraocular lens will be implanted in its place. The presence of an ICL does not prevent you from having other eye surgeries in the future.
The procedure itself is not painful because we use numbing drops and often mild sedation to keep you comfortable. You may feel pressure or slight sensations during the surgery, but you should not experience sharp pain. After the procedure, some patients have mild discomfort, scratchiness, or light sensitivity for a day or two, which can usually be managed with over-the-counter pain relievers and your prescribed eye drops.
