What is posterior capsular?

What is posterior capsular?

Posterior capsular opacification (PCO) occurs when a cloudy layer of scar tissue forms behind your lens implant. This may cause you to have blurry or hazy vision, or to see a lot of glare from lights. PCO is fairly common after cataract surgery, occurring in about 20% of patients.

Is posterior capsulotomy necessary?

Posterior capsulotomy is a laser surgical procedure which is sometimes necessary to clear vision after cataract surgery.

What causes tight posterior capsule?

Posterior capsule tightness (PCT) is a soft tissue alteration commonly described in overhead athletes. The tightness is described as an adaptation to repetitive high tensile loading on the posterior shoulder capsule during the deceleration phase of throwing,13 which may stimulate posterior capsule fibrosis.

How safe is posterior capsulotomy?

Comment. NdYAG capsulotomy is generally a safe and successful method in relieving the symptoms of posterior capsular opacification. Documented complications include, transient rise in intraocular pressure,2 retinal detachment,3 lens subluxation or dislocation,4 lens pitting,5 and exacerbation of local endophthalmitis.

How long does a posterior capsulotomy take?

Your surgeon will carefully direct a laser beam into your eye. The beam will make a hole in the clouded capsule behind the lens so that light will be able to pass through this to the back of the eye. The procedure usually takes five minutes and is not painful.

Can posterior capsular opacification go away by itself?

Blurring and loss of vision from posterior capsule opacity is usually gradual, just as with real cataracts. While the symptoms are very similar to cataracts, there is no chance of an actual cataract re-forming after cataract surgery.

Can posterior capsulotomy be repeated?

Posterior capsular opacification (PCO) is common after cataract surgery. Recurrence is very rare after a successful Yttrium aluminium-garnet (YAG) capsulotomy in adults. We report a case of visual axis re-opacification after a successful YAG capsulotomy for PCO in an adult.

Is posterior capsulotomy covered by Medicare?

Medicare covers YAG laser capsulotomy if it’s medically necessary due to complications from cataracts and cataract surgery, which typically includes a diagnosis of posterior capsular opacification.

How can posterior capsular opacification be prevented?

The most important contribution to preventing PCO is to use an IOL with a square edge. In particular, I recommend using a 360° square-edged IOL. I do not think that the implantation of a capsular tension ring can reduce the incidence of PCO.
