How to use SimVis to explain halos?
How pre-surgical halo simulation improves patient understanding, reduces postoperative complaints and enhances outcomes in modern cataract and IOL procedures.
Experience before surgery
Halo simulation in real counselling flow
From explanation to experience
Patients understand optical trade-offs before surgery
Before simulation
Halos are explained verbally, often remaining abstract and difficult to contextualize.
With SimVis
Patients directly perceive the effect, making the conversation clearer and more actionable.
Is there a problem with the current way doctors talk about halos?
Dysphotopsia—especially halos, glare and reduced contrast sensitivity—remains a leading cause of postoperative dissatisfaction in cataract and refractive lens surgery.
Even with advances in IOL technology and surgical precision, many patients experience visual effects they did not fully anticipate.
In a landscape where expectations are as critical as outcomes, aligning perception with reality has become a key clinical challenge.
Traditional pre-operative counselling often relies on explanations that describe the phenomenon, but do not truly let patients experience it.
How to make patients undersand their future vision?
This gap between expectation and outcome is a major driver of complaints, particularly in premium IOL cases.
Pre-surgical visual simulation is transforming this paradigm by allowing patients to experience halos before surgery.
The result is better understanding, stronger decision-making and a more confident surgical journey for both patient and clinician.
This perception gap can lead to anxiety, repeated consultations, reduced trust and, in some cases, explantation of otherwise well-functioning lenses.
Pre-surgical simulation helps turn a difficult conversation into a more intuitive one: patients can understand halos not as an abstract warning, but as an experience they can recognise before surgery.
