Evo Visian ICL has been approved by the local health authority, which means it is safe and effective. As with any procedure, there are risks to consider.
Over or under correction
The most common complication with any refractive procedure is overcorrection or under-correction. We take every precaution to take meticulous measurements before your procedure to ensure the right amount of correction is prescribed. Because the EVO lens can be removed, we can make adjustments to reduce any overcorrection or under-correction. The same risks apply to the second surgery.
Halos & night glare
There is a possibility of halos and glare around lights at night in any refractive procedure like Lasik, PRK or EVO Visian ICLs.
Damage to the crystalline lens
Since we place the EVO lens inside the eye, there is a potential risk of touching the eye’s natural (crystalline) lens. This could cause an opacity (cataract) of the lens. In the most serious case, we may need to remove the cataractous natural lens and replace it with a synthetic lens. This problem occurs in less than 1.5% of patients.
Increase in eye pressure
In some cases, an increase in eye pressure can occur as a result of the procedure. In the event of this occurrence, your doctor may quickly correct the problem with additional medication or surgical intervention. If not corrected or left untreated, the increased pressure could result in loss of vision. Remember to speak with your doctor about your personal situation and considerations.
Risk of infection
All surgical or refractive procedures involve invasiveness, which means there is a risk of infection. While uncommon, it’s important to realise that an eye infection can have a range of results, from delayed healing to serious eye damage. We try to reduce this risk by starting with sterile products used in a minimally invasive procedure and preventative treatments administered to the affected area.
Loss of visual acuity
While extremely rare, all refractive procedures can damage the eye, including the loss of visual acuity, including in most severe cases loss of functional vision.
Iridotomy complications (if iridotomy is required)
During the iridotomy phase of the pre-op treatment, we can use a laser to make small incisions in the eye. Complications from this incision rarely occur but can cause natural lens or corneal damage, inflammation, increased intraocular pressure, bleeding and scar formation. Iridotomies are not required for all lens models. We will let you know at your appointment if your lens model requires this step.
