A new approach to experiencing visual outcomes before cataract and presbyopia surgery
Choosing an intraocular lens (IOL) is one of the most important decisions in cataract and refractive lens surgery. While biometric calculations predict refractive accuracy, they do not fully capture how a patient will perceive visual quality in daily life. Uncertainty about halos, depth of focus and spectacle independence often generates anxiety before surgery.
SimVis Gekko2 is an optical simulation technology designed to allow patients to experience potential visual outcomes before implantation, supporting better-informed decisions and improved expectation alignment.
¿Qué es SimVis Gekko2?
SimVis Gekko2 is an ophthalmic visual simulation device developed to reproduce how different intraocular lens designs may affect vision prior to surgery.
Unlike traditional counseling methods that rely on explanation alone, SimVis Gekko2 aims to provide experiential insight by recreating optical characteristics associated with various lens profiles.
It allows:
-
Comparison between monofocal and presbyopia-correcting lenses
-
Simulation of depth-of-focus behavior
-
Demonstration of potential light distribution patterns
-
Structured support for shared decision-making
The technology is grounded in optical research and developed within a scientific framework associated with advanced vision science.
Why was SimVis Gekko2 developed?
Modern cataract surgery has become refractive in nature.
Patients increasingly ask:
-
Will I still need glasses?
-
Will I see halos?
-
Can I know how I will see before surgery?
Traditional explanation may not fully address these concerns.
As highlighted by the American Academy of Ophthalmology, expectation management plays a central role in patient satisfaction.
SimVis Gekko2 was developed to bridge the gap between explanation and perception.
How does SimVis Gekko2 work?
SimVis Gekko2 uses controlled optical modulation to reproduce visual effects associated with different intraocular lens designs.
It does not implant or test a physical lens.
Instead, it:
-
Modifies light patterns entering the eye
-
Simulates depth-of-focus characteristics
-
Demonstrates potential photic phenomena
The goal is not to guarantee an exact postoperative result, but to provide realistic experiential insight before a permanent decision is made.
Who can benefit from SimVis Gekko2?
SimVis Gekko2 may be particularly valuable for:
-
Patients considering multifocal or EDOF lenses
-
Individuals concerned about night vision quality
-
Patients unsure about reducing glasses
-
Clinics focused on premium differentiation
It supports shared decision-making by making visual trade-offs tangible.
Does SimVis Gekko2 replace surgical planning?
No.
SimVis Gekko2 complements biometric calculations and clinical evaluation.
Biometry predicts refractive power.
Simulation addresses perception and expectation.
Both are part of comprehensive pre-surgical planning.
Is the simulation result guaranteed?
No visual simulation system can perfectly predict subjective perception after surgery.
Visual outcome depends on:
-
Ocular health
-
Neural adaptation
-
Individual sensitivity
-
Residual refractive factors
However, experiential insight reduces uncertainty and improves decision confidence.
Why expectation alignment matters
Research published in leading ophthalmology journals consistently shows that postoperative dissatisfaction is often related to expectation mismatch rather than surgical inaccuracy.
Professor David F. Chang has emphasized that meeting expectations is central to satisfaction in refractive cataract surgery.
Technologies that support expectation alignment contribute to better overall patient experience.
