The EVO Visian ICL ( Implantable Collamer Lens) phakic lenses are an innovative product created by the STAAR Surgical company.
What is a phakic lens?
It is a kind of contact lens, placed on the inside of the eye. Permanently. Perfectly selected and ideal for your visual defect.
Phakic lenses are a highly advanced intraocular lens technology. The EVO VISIAN ICL lenses are implanted between the iris and the eye’s natural lens. The lens aims to correct visual defects by operating inside the eye.
The phakic lens remains in the eye permanently, but can be replaced should the patient’s vision deteriorate.
The phakic lenses work in tandem with the eye, and enable visual defect correction. It is the ideal method for those wanting to rid themselves of glasses or contact lenses, but do not qualify for laser vision correction.
A phakic lens is made from a technologically advanced material called collamer.
„Collamer” was patented by the STAAR Surgical company. It is composed of collagen, po-li-HEMA copolymer, and chromophore benzophenon. It is hydrophyllic and has a high water content reaching 40%. The lenses made out of collamer are highly biocompatible, chiefly due to the addition of collagen. The collagen attracts the fibronectin naturally present in the eye, creating a protective layer around the lens.
High biocompatibility means the phakic lenses are very well tolerated.
The material’s properties are almost identical to those of the human eye’s natural lens.
Visian ICL phakic lenses contain a UV filter, stopping the harmful UVA and UVB radiation from reaching the most sensitive parts of the eye.
Due to these filters, we can prevent the spread of many serious illnesses, some of which (e.g. age-related macular degeneration) can lead to irreversible loss of eyesight.
Who qualifies for the phakic lens implantation procedure?
People wanting to remove glasses and/or contact lenses from their lives
- ages from 21 to 55
- myopic from – 0,5 to -18 diopters
- farsighted from +0,5 to +10 diopters
- astigmatism up to +6D
- a stable visual defect
If the defect is higher than basic, the final decision about the procedure viability is made by the ophthalmic doctor during the qualifying examination.
The treatment is usually used with high visual defects (myopia, farsightedness, astigmatism).
Our ophthalmic clinic usually offers this treatment to people who did not qualify for the laser vision correction for a variety of reasons (too thin cornea, drye eye syndrome, etc.)
How long does the phakic lens implantation procedure take?
The procedure itself takes approx. 20-30 minutes. Added to this must be the preparation period in the clinic, and the time taken for the check-up immediately following the procedure. The combined total stay should take approx. 2-3 hours.
During the procedure only one eye is operated on. The other eye is treated usually within a week or fortnight.
Benefits of phakic lens implantation
- Reversible, the lens may be removed
- No risk of „Dry eye syndrome”
- Rapid achievement of full vision, with good vision only two days after
- Perfect for people with thin corneas
- Contains a UV filter, stopping UVA i UVB radiation
- 99,4% of patients would undergo the procedure again
What are the counterindications to implantation?
Most frequent reasons for not performing the procedure:
- Under the age of 21
- Pregnancy and breastfeeding
- An unstable visual defect
Additional factors precluding the ability to perform the procedure include:
- Conditions following intraocular treatments Stan po zabiegach wewnątrzgałkowych
- Central retina degeneration
- Conditions following uveitis
- Corneal endothelial cell disfunction
- Conreal dystrophy
- Narrow pupils with a weak response to mydriasis
- Connective tissue disease – collagenosis, etc.
Qualification for phakic lens implantation
All patients wishing to undergo the phakic lens implantation must first take a detailed qualifying examination, based on which the doctor will make the decision whether or not the treatment can be performed.
On the day, it is worth taking some time off because the entire qualification lasts from 1.5 to 3 hours. The obtained results allow for visual defect assessment, and help select the best-fitting lens for the patient.
Qualifying examination procedure involves:
- Digital refraction error test and a subjective visual acuity evaluation with the best correction and without it
- A slit lamp test, which allows to evaluate the state of both the frontal and posterior eye segment (macula, optic disc, and the entire retina), as well as the translucency of optical centres
- Corneal topography, testing the exact shape, thickness, and curvature of the cornea
- Intraocular pressure measurement, including corneal elasticity
- Optical biometry
- Pupil diameter
- Endothelial cell density
- Drainage angle evaluation
- Medical interview
Following the detailed ophthalmic examination the patient will, together with the doctor, select the most appropriate Visian ICL lens for them.
WARNING: During diagnostics, pupil-dilating eyedrops are used. The affect the eye increasing light sensitivity (the pupil will not narrow on its own) causing worse vision. The vision reduction can last up to several hours. Due to this, following the examination you will not be able to operate any vehicles (it is highly dangerous).
If you wear contact lenses, read this carefully!
If you make use of contact lenses every day, then prior to the qualifying examination you must switch to glasses. This is very important, because the contact lens changes the shape of the cornea, which in turn causes inaccurate test readings.
If you don’t have any corrective glasses at home, do not worry. Our experts will quickly pick the appropriate strengths or you and write out a prescription.
For how long should you not wear contact lenses?
– soft contact lenses – for two weeks prior to the examination
– hard contact lenses – for four weeks prior to the examination
Between treating the first and the second eye, you must not wear contact lenses on the treated eye. The lens must be removed at least 3 days prior to the surgical treatement.
The decision to qualify the patient for a phakic lens implantation is made by an ophthalmic doctor, specialised in Visian ICL lens implantation.
After qualifying for the phakic lens implantation procedure… how to prepare for the procedure, and what to remember
All that remains for us now is to prepare for the procedure.
Do not cease taking any regular medication.
It is the safest option to forgo eye make-up for 24 hours before the procedure. On the day do not apply any make-up on the rest of your face.
During the first days following the procedure, the ophthalmic doctor will certainly discourage applying eye make-up. You may of course use face creams without worry – provided you avoid areas around the eyes.
When can eye make-up be applied again? This is a very individual concersn and it is worth talking to your doctor about it during the second control check-up.
It is recommended to wear comfortable clothing during the procedure, for example, sweats and comfortable shoes.
Tests and family doctor evaluations
The phakic lens implantation procedure is performed with anesthesiological assistance. This will require a diagnostic blood test and an evaluation from your family doctor or GP.
Time off work
Most patients can return to work without worry as soon as a few days post-procedure. For their own comfort and safety, however, it is recommended to plan several days of rest to allow the eyes to recover. It is worth considering taking time off work, especially on the week between the first and second eye surgery. The second eye is operated on 1-2 weeks after the first.
As opposed to eyeball surface reshaping procedures such as LASIK, lens implantation procedures are not performed on both eyes on the same day. We usually wait the minimal period of a week before implanting the second ICL lens.
For 24 hours prior to the procedure, and 48 godzin afterwards, you must refrain from alcohol consumption. It negatively impacts eye hydration. It’s also recommended to forgo the use of perfume and other high-alcohol content products.
On the day of the procedure, refrain from energy drinks, soda, or strong coffee. We recommend the last meal to be eaten at least 4 hours before the procedure, and the last drink and hour before.
Usually, our patients exhibit vehicle-operating-standard vision as soon as a few days after the procedure; it remains impossible, however, immediately afterwards.
Please arrive for the procedure with a companion. Your return home (or to the hotel) must be overseen by a companion.
Following a phakic lens implantation, it is recommended to rest for a few days in a calm place. It is not recommended to undergo long and tiring journeys immediately following the procedure. There are, however, no counterindications to air travel.
Post-procedure control check-ups
The next day after the procedure we conduct a compulsory control check-up.
Patients arriving from afar are offered a hotel reservation, placed near out Ophthalmic Centre.

Recovery following the phakic lens implantation procedure
- We recommend no swimming in the forst two weeks after the surgery (due to the theoretical danger of infection)
- Attempt to keep your eyes closed while taking showers. Avoid rinsing the eyes.
- Use only the prescribed eyedrops and remove mucus deposits in the corners of your eyes using hygenic sticks moistened with boiled and cooled water.
