What are the lens replacement risks?


Lens replacement surgery is like any other operation. It has its own benefits and risks. The risk varies from a very mild, or it could be something more serious that requires additional operations.

Patients after surgery might complain of dry eyes, and this usually lasts between three to six months. Still, it clears quickly and very rarely it remains a problem. Some patients might experience a bit of elevated intraocular pressures, but again, most of the time this clears on its own. Occasionally you might need some special treatment which we call glaucoma management treatment...

There are other risks that could be related to the type of lens implants. As the monofocal lens is doing one task, the quality of the image is very good, especially in terms of contrast sensitivity. When it comes to multifocal lenses implant, however, there might be a bit of compromise on the best-corrected vision or the contrast sensitivity; some patients might describe that the vision is not as sharp as they expected.

Also, glare and halos are often experienced with multifocal lenses. Usually, this wears off gradually, so almost every patient will see a little bit of glare and halos immediately after the operation, but within a few months, this will become less and less, and then they disappear.

The multifocal lenses require a good illumination, especially when it comes to reading small print. We’ve always known that they don’t work so well in dim light and you need good lighting when you do near tasks.
