What does it mean when you have a dense cataract?
A dense brunescent cataract usually has little-to-no epinucleus, because it has stiffened and become a part of the nucleus. The posterior capsule therefore has no protective layer to guard it against laceration by sharp, bulky nuclear fragments.
Are dense cataracts hard to remove?
Hard, dense nuclei are difficult to remove with phacoemulsification or SICS. You may prefer to do a routine extracapsular extraction. Hypermature cataracts have a small nucleus and a wrinkled capsule.
Can a thick cataract be removed?
Surgically, the goal for a dense cataract is to remove the lens while minimizing endothelial damage, avoiding wound burn and intraoperative complications, and minimizing postoperative inflammation, Al-Mohtaseb said. Often, patients with these types of cataracts have small pupils.
How big do cataracts have to be before they can be removed?
A cataract does not have to become “ripe” before it can be removed. In the past, the lens could not be extracted safely from the eye unless it was at a relatively advanced stage of development. With modern advances in cataract surgery, the lens can now be removed from the eye at any stage of development.
What is the main cause of cataract?
Most cataracts develop when aging or injury changes the tissue that makes up the eye’s lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts.
Why is cataract surgery not recommended?
For example, if you have advanced macular degeneration or a detached retina as well as cataracts, it’s possible that removing the cataract and replacing it with a clear intraocular lens (IOL) might not improve your eyesight. In such cases, cataract surgery may not be recommended.
What happens if cataract not removed?
Over time, cataracts become worse and start to interfere with vision. Important skills can be affected, such as driving, and loss of vision can affect the overall quality of life in many ways including reading, working, hobbies and sports. If left untreated, cataracts will eventually cause total blindness.
Is cataract surgery a difficult procedure?
Cataract surgery is quick and painless. It’s an outpatient procedure, and you can expect to be in and out in under an hour. There’s no pain thanks to numbing eye drops you’ll receive before the procedure begins. Your surgeon will make an incision in your eye.

Cataract surgery is very common and is generally a safe procedure.
Can you get rid of cataracts without surgery?
