There are many different types of artificial lenses and it’s important to talk to your doctor about which best meets your needs.
Monofocal vs multifocal
Monofocal lenses have a single focal point and will help you to focus on one point (usually in the distance). You’ll probably need glasses for near vision. These are the lenses used in most cataract surgeries.
Multifocal lenses enable you to focus on distance as well as near vision. They may reduce your need for reading glasses. Some people with this type of lens experience increased glare and loss of contrast.
Your ophthalmologist will explain which type of lens is the best option for you.
Aspheric vs spherical lenses
Aspheric lenses have a shape and optical quality that more closely resembles your eye’s natural lens. So they can produce sharper vision, especially in low light conditions and if you have larger pupils.
Spherical lenses don’t match the shape of the natural lens, so they can induce minor imperfections into your vision. The imperfections can affect your quality of vision, especially in low-light conditions, such as driving at night.
There are aspheric and spherical versions of both monofocal and multifocal lenses.
A toric lens is a used to correct astigmatism, a condition in which light doesn’t focus properly on the back of the eye due to irregularity in the curvature of the front part of the eye (the cornea). If you have astigmatism, you may benefit from a toric artificial lens.
Before deciding on a lens, check if there are out-of-pocket costs, as some types – like multifocal and toric lenses – may be more expensive than others. When you’re weighing up the cost of lens implants, don’t forget to add in the cost savings you may get if you don’t need glasses after your surgery.
