Blended vision
The dominant eye is set for distance and the other eye slightly nearsighted, so that between them the brain has a clear image at most distances. With laser correction, the EVO ICL or monofocal lens implants, it reduces reading glass use substantially for most patients who tolerate it, and a contact lens trial beforehand shows whether you will. Depth perception is slightly reduced, and fine print in dim light may still need readers. It suits patients in their forties whose lens is still clear.
Multifocal and trifocal lens implants
Replacing the natural lens with a trifocal such as PanOptix gives distance, intermediate and near vision in each eye, and most patients read, work and drive without glasses. The trade-off is halos around lights at night, which fade for most patients over months, and a need for a healthy macula and regular cornea. It is the most complete route to independence and is chosen by many patients over 45 in Refractive Lens Exchange and at cataract surgery.
Extended depth of focus lenses
Lenses such as Vivity and Symfony give a continuous range from distance through intermediate with fewer night visual effects than a trifocal. Everyday near tasks are usually comfortable; small print often needs light readers. Blending EDOF lenses between the eyes improves near vision. For patients who drive at night or work at screens, this is often the preferred compromise.
The Light Adjustable Lens
At cataract surgery, set as blended vision and fine tuned after surgery, the LAL lets you try the balance between distance and near before it is locked in, with monofocal clarity and fewer halos than multifocal lenses. It suits patients who prize night vision and want blended vision set precisely.
Non-surgical routes
Multifocal contact lenses reduce readers for many patients and can be trialed easily. Presbyopia-correcting drops constrict the pupil for several hours of improved near focus and suit occasional use. Neither is permanent, and both are reasonable ways to test what you want before considering surgery.
Choosing
The consultation examines the lens, the macula, the cornea and the tear film, asks how you use your eyes and how you feel about night halos, and recommends the approach that fits. The likely result, and when you may still reach for readers, is set out plainly.
