Vacuoles and more dense granular deposits (plaques) can progress peripherally in a sharply demarcated platelike configuration. Posterior capsular opacification is a multifactorial disease and is influenced by the increased levels of several cytokines and growth factors, including TGF-β, FGF-2, hepatocyte growth factor, IL-6, and epithelial growth factor. The side effect is called posterior capsule opacification, also known as a secondary cataract. We found a significant decrease in the BCVA and increase in the OSI with the development of posterior capsule opacification. This may cause you to have blurry or hazy vision, or to see a lot of glare from lights. The procedure is performed by an ophthalmologist (eye surgeon).

Complications are uncommon but may include retinal detachment, IOL damage, cystoid macular edema, increased intraocular pressure, iris hemorrhage, corneal edema, IOL subluxation, iritis, macular hole, corneal endothelial cell loss, and exacerbation of localized endophthalmitis. In this approach, the emulsified material is aspirated out of the eye through the handpiece in a manner similar to phacoemulsification. 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). Posterior capsule opacification (PCO), also known as after-cataract and secondary cataract, is the most prevalent complication following cataract surgery. 2005;31(4 .

Over time after cataract surgery, the posterior capsule may lose its clarity. The decrease of BCVA was statistically correlated with the increase of OSI (r = 0.812, P < 0.01).In patients who reported visual disturbances without decreased visual acuity, OSI decreased to <1.3 and subjective symptoms were resolved in all cases although there . Cause And Symptoms. This opacification affects 30-50% of the patients. This is caused by some lens epithelial cells (LECs) remaining in the capsule. Potential complications of untreated CBS include: glaucoma, posterior capsule opacification, and posterior synechiae [4]. examined the capsular bags with IOLs in 190 donor eyes. Posterior capsule opacification (PCO, secondary cataract, after cataract) is a nagging postsurgical complication following extracapsular cataract surgery (ECCE) and intraocular lens (IOL) implantation. However, in some cases, a hazy membrane can form just behind the intraocular lens implant. You are not able to tolerate brilliant sunlight either as this type of cataract leads to greater scattering of light. The text that follows aims to provide a background of events following cataract surgery, the study systems that can inform and lead to better . Usually the vision is decreased, particularly while reading. Posterior capsular opacification is a result of clouding of a membrane that surrounds the replacement lens implanted during cataract surgery.

The YAG Laser Procedure The capsulotomy requires the use of a Nd:YAG (Neodyium - doped yttrium, aluminum, and garnet) laser, which is generally just called a YAG. Posterior Capsule Opacification 1 Part of the tissue covering the lens (the capsule) is left to help hold the IOL in place. PCO may be associated with capsular bag distension and cyst-like structures at the posterior capsule. Posterior capsule tightness leads to GIRD (glenohumeral internal rotation deficit). Some patients report that it seems as though their . The back (posterior) part of the capsule which is just behind the artificial lens can become cloudy (opacify) in up to 10-20% of eyes that have undergone routine uncomplicated cataract surgery.
