Most surgeons counsel patients on premium IOLs from outside the experience. They know the optics, the data, the published outcomes. They have not lived inside the visual world they are recommending.
Mr Mfazo Hove counsels from inside it.
He has bilateral ZEISS AT LISA tri 839MP trifocal IOLs implanted in his own eyes. He chose the lens after years of implanting it for patients, performing the surgery, following the outcomes, and watching his own near vision change with age. The decision was clinical. The experience now informs every counselling conversation he has on trifocal IOLs.
What Personal Experience Adds to Counselling
This matters in concrete ways:
Neuroadaptation is real and time-bound. It does not happen instantly. The first weeks involve learning, the next months involve refinement, and somewhere around six months the new visual world becomes the only world. Counselling that does not describe this trajectory honestly leaves patients unprepared for it.¹
Haloes recede in subjective awareness without disappearing in measurement. A patient who hears “the haloes are still measurably there at six months” panics. A patient who hears “the haloes recede in your awareness even though they remain detectable in formal testing” understands the actual experience.
The trade-offs are real. Reading menus in dim restaurants is harder than it was at twenty. Threading a needle is harder than it was at twenty. These are not catastrophes, they are trade-offs that come with the package, and patients who hear about them in advance accept them. Patients who do not, do not.²
The Limits of Personal Experience
The lens is not for everyone. A surgeon who can describe his own decision can also describe the patients for whom it would have been wrong. That ability is the heart of honest counselling.³
Trifocal IOLs are a powerful tool for the right patient. The right patient is identified by a consultation that draws on data, on volume, and, when it is available, on personal experience.
Who This Is Not For
Patients seeking a lens recommendation independent of the surgeon’s actual judgement. Personal experience is not an argument for trifocals; it is one input among several.
Clinical Takeaway
Personal clinical experience adds dimension to counselling that data alone cannot replace. It does not replace data, it complements it.
