Pupils are frequently dilated on the daytime before cataract surgery and for retinal detachment surgery so the fundus can be examined.
The lens sit right trailing the pupil. You have to know how to get to it.
Cataracts are spots on the lens of the eye. To bring to the lens you must dilate the pupils to get to the cataract to fix them.
I'm not a physician but am an ex cataract surgical rep. The reason the pupil is dialated prior to the procedure is to faciliatate a better picture of the cataract and to allow it to be more easily removed from the eye. Dialating the pupil is standard procedure for adjectives cataract surgeries.
During the actual removal of the cataract a physician inserts a tiny needle that emit sound side at a very dignified frequency. These sound top break up the cataract which is then removed through the tip of the hypodermic.
Once the cataract has be removed, an implantable silicone lens will be inserted in its place and will allow night light to focus on the retina. This will restore your vision.
From around 3 months out from the surgery or later, you could originate to notice a haziness contained by your vision. This is not the formation of a unusual cataract. A simple procedure known as a Yag procedure will clear this right up. It's painless, does not require anesthesia or anything and can be perform in smaller amount than 5 minutes. Whether or not you have to own this procedure done is dependent upon a lot of things but it should be your end step in restoring your trance.
