Many patients hear anecdotes or advertising suggesting they’ll have vision “better than ever” after cataract surgery – and often, vision does improve dramatically – but it’s important to dispense with the idea of absolute perfection.

First, human eyes even at their best have limitations – for example, as we age, even after cataract surgery you may need more light to read small print or more contrast to see fine details. If you expect to never wear any glasses again for any task, that could be unrealistic unless you opt for certain lens strategies (and even then, you might still use readers in dim light or very fine print).

Also, some premium lenses (MFIOLs) come with small compromises like halos; they provide great functional vision but not a “bionic” perfect eye. Other premium lenses (LAL), provide high quality, sharp vision and the ability to choose how you see after surgery, but they do  not offer full range of vision – we utilize strategies like blended vision to reduce your dependence on readers if you choose LAL.  Another aspect: if you have other eye issues (mild macular degeneration, early glaucoma), cataract surgery fixes the lens but not those conditions – so while things will be clearer, some distortion or missing pieces from other diseases might remain. Some patients think cataract surgery will also fix long-standing issues like lazy eye (it won’t change an amblyopic eye’s vision much), and unfortunately that is not true.

We also aren’t going to remove your floaters at the time of surgery (not yet anyway! That may happen in the future though!) The good news is cataract surgery can often restore vision to how it was in youth when colors were bright and images clear – that can feel “perfect” compared to living with a cataract. But expecting supervision (like microscopic reading of far-away signs at night in the rain without glasses) is setting the bar unrealistically high. By removing the myth of perfect, we set the stage for excellent vision that you can appreciate without fixating on tiny imperfections. And if your outcome is really outstanding (which it frequently is), it’ll feel like a wonderful bonus.
