What does posterior capsule opacification look like?
Over time, the capsule can become clouded by various proteins within the eye. Posterior Capsule Opacification symptoms are very similar to cataract symptoms. These include: blurring of vision, glare in daytime or when driving and difficulty seeing near objects that were clear after cataract surgery.
Why does PCO occur?
PCO occurs because cells remaining after cataract surgery grow over the back (posterior) of the capsule causing it to thicken and become slightly opaque (cloudy). This means that light is less able to travel through to the retina at the back of your eye.
How do they fix astigmatism after cataract surgery?
Another way to correct astigmatism during cataract surgery is called limbal relaxing incisions (LRI). In this procedure, one or more arc-shaped incisions are made near the periphery of the cornea. This gently reshapes the cornea into a more spherical shape, eliminating astigmatism.
What is the purpose of toric lens?
Toric contact lenses are designed for people with astigmatism. Toric contact lenses correct for astigmatism issues that arise from a different curvature of the cornea or lens in your eye (referred to as regular astigmatism, corneal astigmatism or lenticular astigmatism).
What causes PCO after cataract surgery?
What does PCO vision look like?
Sight can become blurred and cloudy, or you may have problems with bright lights and glare. The effects of PCO on your sight are very similar to the changes you may have had when your cataract first started to cause you problems.
Why do I need a YAG capsulotomy?
YAG laser capsulotomy is surgery to help you see clearly after cataract surgery. You may need this surgery because months or years after cataract surgery, your vision may get fuzzy again. This happens when a membrane in your eye, called the posterior capsule, becomes cloudy.
What are IOL implants for cataract surgery?
IOL Implants: Lens Replacement After Cataracts. The lens bends (refracts) light rays that enter the eye, helping you to see. Your lens should be clear. But if you have a cataract, your lens has become cloudy. Things look blurry, hazy or less colorful with a cataract. Cataract surgery removes this cloudy lens and replaces it with a clear IOL…
Why is my lens capsule clear after cataract surgery?
Your lens capsule is clear and remains clear following your cataract surgery. PCO occurs because cells remaining after cataract surgery grow over the back (posterior) of the capsule causing it to thicken and become slightly opaque (cloudy).
What happens during cataract surgery?
During cataract surgery, the cloudy lens inside the eye is removed and replaced with a clear artificial lens implant. The cataract is surrounded by a clear cellophane-like wrapping. During cataract surgery, the front cellophane wrapping is removed. Then the cataract is removed and the implant placed.
What happens to the cellophane wrapping after cataract surgery?
The cataract is surrounded by a clear cellophane-like wrapping. During cataract surgery, the front cellophane wrapping is removed. Then the cataract is removed and the implant placed. The back cellophane wrapping (known as the posterior capsule) remains intact.
