Monofocal lenses are standard lenses used in cataract surgery. People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes ...
However, people receiving multifocal lenses may experience more visual problems than with monofocal lenses. [6] The most common adverse visual effects from multifocal IOLs include glare, halos (rings around lights), and a loss of contrast sensitivity in low-light conditions. [13]
Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [4] [10] Cataracts usually develop slowly and can affect one or both eyes. [4]
If this does not help, surgery to remove the cloudy lens and replace it with an artificial lens is the only effective treatment. [1] Cataract surgery is not readily available in many countries, and surgery is needed only if the cataracts are causing problems and generally results in an improved quality of life. [1] [11] [4] [12]
IOLs can be used to correct other vision problems, such as toric lenses for correcting astigmatism. [38] IOLs can be classified as monofocal, toric, and multifocal lenses. [39] Ocular anaesthesia has improved since Alfred Einhorn synthesised procaine in 1905, which was used in retrobulbar anaesthesia.
Surgery [ edit ] Multifocal intraocular lens implantation is a new possible treatment involving clear lens extraction and multifocal intraocular lens implantation [ 5 ] but it may not be appropriate for patients who have had resistant spasm of accommodation for a long period of time.

Multifocal intraocular lenses are designed to avoid the need for glasses by providing two or more points of focus. Multifocal glued IOL procedures have been done with the ReZoom (Abbott Medical Optics), and Tecnis (Advanced Medical Optics (AMO)) IOLs. This makes it possible to offer the accommodative IOL advantage even to patients with an ...
