Understanding the Different Types of Lenses Used in Cataract Surgery

Cataract surgery usually requires that the surgeon remove the cloudy natural lens in your eye and replace it with an artificial one. This lens should be pre-loaded since it offers shorter, safer and no-touch insertion of the lenses during the surgery. Such lenses while loaded in advance help to make the procedure more smooth and precise.

Unifocal lenses are the simplest type of lenses and are quite popular in use at the moment. They are specifically tailored to give clear vision at a particular distance. This implies that with a Unifocal lens, vision is clear either at distance or near but not at both. If you select a lens for distance vision only, for instance, you may be required to wear glasses for near work. On the other hand, if you choose a lens for near work, you may require eyeglasses for distant vision. Unifocal lenses are simple and provide clear vision for those who do not need to have vision at more than one range.

Alternatively, EDOF lenses enable a broader field of vision as opposed to Unifocal lens. It is a type of lens which has the ability to assist in seeing distant objects and have some capacity for near visions. However, the near vision offered by the EDOF lenses is not so sharp. It can be used for any given activity but if one requires to read small text or do some work in detail then the EDOF lenses may not be very suitable. Although they have their drawbacks, EDOF lenses can help minimize dependence on glasses for everyday tasks.

The PanOptix by Alkon is a multifocal lens intended for use in offering clear vision for different ranges. This simply means you don’t have to wear one glass for distance vision and another for close work as you are able to do both comfortably. Multifocal lenses are particularly helpful when it comes to people that have multiple working distances like reading and driving. However, sometimes they can lead to glares such as when you are driving especially at night. If you often drive in the dark then EDOF lenses might help to eliminate glare.

Choosing the Right Lens

When choosing between these lenses, it is advisable to look at how you will use them and your visual requirements. For most people, multifocal lenses are a convenient option, however, if you experience glare problems or require vision primarily at close distance, EDOF lenses will be more suitable for you. There are certain advantages and possible disadvantages to each type of lens, but it will be easier for you to decide what is best for you, let’s consult with best eye doctor in Ludhiana.
