Cataract surgery usually takes about 15 minutes and is performed under light sedation. We provide ample anesthesia; therefore, there is no pain during surgery.
Briefly, cataract surgery consists of the following steps:
- A small opening is made on the surface of the eye.
- Specialized instruments are used to break up and remove the lens.
- A lens implant is then placed.
Choosing the Right Intraocular Lens
We offer 3 different kinds of intraocular lenses.
Regardless of which lens you choose, after cataract surgery, your vision is expected to get better. You may or may not need glasses depending on which intraocular lens you choose.
3 types of intraocular lenses
(a) Monofocal Lens
The monofocal lens allows you to see well at a fixed distance. Most people prefer to have the lens set for far vision. After surgery, reading glasses will be needed for near vision.
(b) Mutifocal Lens
The mutifocal lens allows you to see well both far and near. For most of your daily activities, glasses may not be needed.
(b) Toric Lens
The toric lens corrects coneal astigmatism. If you have astigmatism correction in your glasses, the toric lens may help to reduce your need for glasses. You may still glasses for near vision.
The Mutifocal and Toric lenses are not covered by insurance. Please consult your doctor to see if you are a good candidate for these lenses.
Differences in Range of Vision (Monofocal Lens vs. Multifocal Lens)
The Monofocal lens allows you to focus at a set distance. For example, if you choose to focus at far, near vision will be blurry and you will need to wear reading glasses. Image quality is very good.
The Multifocal Lens allows you to focus at near, mid, and far distance. Image quality is slightly inferior to the monofocal lenses. However, there are many patients who do not require glasses at all after choosing multifocal lenses. For prolonged reading or reading fine print, glasses maybe needed. With this lens, some patients experience glare immediately after surgery, but most patients experience reduction in such symptom later on. If you have corneal astigmatism or other ocular conditions, you may not be a good candidate for the multifocal lens.
Differences in image quality (Monofocal Conventional Lens vs. Monofocal Toric Lens)
Corneal astigmatism can cause blurry vision with decreased image quality. The monofocal conventional lens does not correct astigmatism and may result in slightly blurry vision requiring glasses both at near and far distance. The toric lens corrects astigmatism and results in good image quality. Testing prior to surgery will help determine if you are a good candidate for this lens. The toric lens is a monofocal lens. You may need reading glasses for near work.
