The Tecnis multifocal lens implant is a cataract surgery involving the removal of the eye's natural lens. The lens is then replaced with a clearer artificial lens implant (IOL).
By 'multifocal, it means that the implanted lens is designed to produce a clearer vision for both near and distant visions without the glasses. This is different from a monofocal IOL, which is designed for specific visions without a clear range of focus.
Tecnis multifocal IOL sets the patient free from using contact lenses.
It uses wavefront technology. The technology corrects visual distortion (optical aberrations) that may cause halos, glare, and low visual quality.
Tecnis is a diffractive lens that comes with concentric rings of distinct power. The rings provide vision at distance and near levels. The lenses are independent of the patient’s pupil size. It improves the reading vision even in low light conditions.
Tecnis multifocal lens implant offers quality vision at multiple distances. The enhanced vision for a specific near point is often personalized to the patient's lifestyle. This allows them to focus on places they use their vision most.
The lenses correct presbyopia and astigmatism while reducing one's dependence on contact lenses.
Beneficiaries of this procedure are patients with healthy eyes who want to stop using glasses at all distances. It cannot work well if the eye has severe glaucoma or macular disease (macular scar or hole, macular pucker, or macular degeneration). Also, Tecnis multifocal lens implant cannot correct astigmatism, especially if it’s significant.
A multifocal lens implant works best when implanted in both eyes. If performed in one eye, the patient may need glasses to accomplish some tasks. This procedure aims to provide independence from contact lenses at every distance.
The good thing about the Tecnis multifocal lens is the lack of risk during surgery. After surgery, a patient may experience some halos and glare with night driving. There’ll also be slight ghosting or blurring or a waxy vision for a short period.
