The visual simulations are a tool that allows the patient to understand how an eye treatment could change their vision, especially in the case of refractive surgery (laser) and in the cataract surgery with premium intraocular lenses (multifocal, trifocal, EDOF or toric lenses).
These simulations are not a substitute for medical assessment, but they are very useful for adjust expectations, The aim is to compare options and help make an informed decision about which technique or lens best suits the individual's lifestyle.
At the clinic in Ali Nowrouzi we use specialised software that integrates objective measurements of the eye, including:
Ocular Aberrometry (high and low order optical aberrations)
Corneal topography (shape and regularity of the cornea)
Ocular biometry (axial length, anterior chamber depth, lens calculation)
Macular status by OCT, where necessary
These simulations are a clinical approach, The use of the new technology is not a guarantee of outcome, but it allows for more accurate and realistic patient-doctor communication.
This test shows an indicative recreation based on objective parameters of the eye. They allow you to understand how you might look with different surgical techniques or lenses, and how visual quality varies according to the option chosen.
They do not represent the exact vision after surgery, but help to anticipate visual sensations and make an informed decision.
It is mainly used in:
Election of premium intraocular lenses in cataract surgery.
Valuation of multifocal lenses or EDOF.
Patients interested in laser surgery to remove glasses.
Situations with irregular astigmatism or optical aberrations where changes should be visualised.
They can also be useful to explain to the patient how certain pathologies (cataract, retinal distortions, corneal irregularities) affect visual quality.
They are reliable as counselling tool, because they are based on precise measurements of the eye.
But they should not be interpreted as a definitive result. Biological factors - scarring, ocular dryness, corneal stability, retinal health - influence the final result.
This is why they are always accompanied by a full assessment and a personalised explanation.
First, the necessary measurements are obtained with:
Macular OCT, if applicable
The software then generates a graphical representation of what the vision might look like depending on the selected lens or technique.
Measurements are usually completed in 5-10 minutes, The simulations are analysed and discussed in the same consultation.
The aim is for the patient to have a clear understanding of what to expect from each option.
No, but they are recommended in cases where there are several equivalent options and the decision depends on the patient's visual preferences:
for example, if you prioritise reading without glasses, intermediate vision, night driving or the highest possible optical quality.
If you are considering laser surgery or an intraocular lens and want to understand how your vision might change with each option, you can book an appointment with Dr. Ali Nowrouzi in Marbella.
Visual simulations will allow you to make a safe and personalised decision.
