1. what is the 'capsule' referred to in cataract posts. Is it the recess into which the implant is inserted?
2. post-op blurring can be either in the capsule or in the implant, I read. YAG laser clears both?
3. How is it that a plastic implant can get a cloudy spot?

Shape and design of IOL especially square edges, better instruments for "polishing" the posterior capsule during surgery.

What has made the difference in the reduction of "secondary cataracts" from the 90's to current rates?
Does the type of IOL material have any impact, Collamer vs silicone for example?

A posterior cloudy membrane "secondary cataract" is NOT a complication of cataract surgery. It occurs due to the continuance of normal human lens physiology. The risk associated with yag capsulotomy are small but will vary from person to person depending on pre-operative degree of myopia, whether there is a family history of retinal detachment or retinal pathology such as lattice degeneration. You should discuss this with your surgeon.

thank you. <i'm acheduled for both eye yag capsulotomy in six weeks after cataract surguery with brilliant inicial success but suddenly deleloped blurry areas. I see that`s a 25-25% risk. Thst's fine- just my luck. But I believe you said the other day that yag has only one chance in1000 of going wrong-? I`ll face it better knowing that. .

2. Wrong, there are many other causes of poor or reduced vision post cataract surgery such as glaucoma, macular degeneration, diabetic eye disease that will NOT be helped by yag capsulotomy
3. It's not the IOL that turns cloudy its the human sack that use to hold the cataract. The cloudy come from the living tissue producing lens fibers that migrate, die and turn cloudy.
4. Great progress has been made in keeping the posterior capsule from turning cloudy (secondary cataract) and the % has dropped from 90%+ in the 80's to about 20-25% now.
