What are the best cataract lens replacements?

Several Options: There are many lens choices for vision correction. Although the standard monofocal implant has stood the test of time (63 years to be exact), it has limited ability to provide you with glasses freedom. Toric implants correct astigmatism, while multifocal and accommodating lenses can provide distance and reading vision without glasses. Ask your eye surgeon about which may work best for you. ...Read more

Premium IOL: Toric iols correct astigmatism . Multifocal and accommodative iols correct presbyopia. Multifocals provide better reading compared to accommodative iols but can result in a degradation in the overall quality of vision and produce side affects such as haloes around lights. Accommodative iols are monofocal so there is no degradation in the quality of vision but don't perform as well for near. ...Read more

What happens when the lens is removed from a baby due to cataracts?

Will need watching: If a cataract is removed in a baby, either a lens implant is placed during surgery, or contact lenses and/or glasses are prescribed afterwards. It is difficult to accurately predict the exact prescription needed in infants because their eyes may continue to grow, causing a change in their prescription. Regardless of which method is used, close follow-up is needed to avoid losing vision over time. ...Read more

Can the lens be replaced if it is put not in the right place after cataracts removal?

Usually: Lenses are rarely put in the wrong place after cataract surgery, even when it is complicated and there are problems. Lenses get out of place when there are variations in the internal anatomy of the eye, fragile components which are unpredictable and some degrees of trauma. These can usually be fixed at a second surgery. ...Read more

When having your cataracts removed, can you have a lens put in to improve your vision?

When having your cataracts removed, can you have a lens put in to improve your vision?

Yes, that is routine: A cataract is the clouding of the eye's natural lens. Virtually all cataract surgery involves removing the cloudy lens and placing an artificial intra-ocular lens (iol) implant in its place. There are some newer more advanced iols that act like intraocular invisible bifocals to minimize need for postoperative glasses (multifocal iols) or to treat pre-exisiting astigmatism (toric iol). ...Read more

Night glare with cataract lenses?

Possibly: I assume you mean intraocular lens implants. If the lenses have not been properly inserted, are multifocal, or if there is a residual refractive error, this may occur, although it is fairly uncommon. Another cause could be opacification of the membrane behind the implant, which can be cleared with the use of a laser. ...Read more
