I'm trying to find out the success rate with this type of surgery but googling only comes up with how complex the surgery is and doesn't really . Cataract surgery is accompanied by a high rate (0−36%) of posterior capsule tear that is attributed to the inherent weakness or the absence of the posterior capsule (5,6). These types of posterior lens opacities can progress over the years and become more visually significant, leading to a decline in visual acuity and necessitating cataract surgery. All surgeries were performed by a single surgeon. 667. Surgery to remove a cataract is generally very safe and has a high success rate. Osher and colleagues (1990) reported a 26% (8 of 31 eyes) incidence of posterior capsule rupture during surgery in eyes with a posterior polar cataract. Posterior polar cataract, a distinctive subtype of lens opacity, presents as an area of degenerative and malformed lens fibers that form an opacity in the central posterior subcapsular area of the. The surgeon needs to adhere to special surgical strategies to minimize the risk of a posterior capsule rupture. Posterior subcapsular polar cataract . Early symptoms can worsen as a cataract increases. A cortical cataract involves the anterior, posterior, or equatorial . Recognize it. Forceful hydrodissection can lead to intraoperative "capsular block syndrome" with rupture of the dehiscent posterior capsule leading to drop of the entire nucleus [ 4 , 5 ]. Every surgeon can expect one, but anticipation and preparation can make a rupture in the posterior capsule a manageable crisis. It causes a small, cloudy area to form underneath the eye's lens. Terry Kim Studies in the peer-reviewed literature report a 26%-36% incidence of posterior capsular rupture with posterior polar cataracts. Osher and colleagues (1990) reported a 26% (8 of 31 eyes) incidence of posterior capsule rupture during surgery in eyes with a posterior polar cataract. You may be confusing it with either a posterior POLAR cataract which does have a higher risk of capsule rupture. Although cataract surgery has been proved to be an effective treatment, its cost and the lack of well-trained surgeons limit its availability in many parts of the world, contributing to its leading course of blindness, especially in developing countries. My technique to handle posterior polar cataract . The value of routine preoperative medical testing before cataract surgery. Schein OD, Katz J, et al. Lens Luxation . Publication types . When located in the back, outer layer of the lens, it's called a posterior capsular cataract. Incidence is not well characterized though they are proportionally less common than most other forms of cataract. Cataract surgery is most effective in the first month after birth. Posterior polar cataracts are associated with remnants of the hyaloid system or tunica vasculosa lentis . In the United States, about 4 million cataract surgery procedures are performed every year.. Cataract surgery is very safe. The visual acuities similarly improved in all eyes in the two groups . the incidence of pcr cited in literature is as high as 36% in eyes with ppc.7 another study reports an incidence of 26%.8 more recently, the incidence has been reduced to 7 and 6%.9, 10 a likely explanation for the low incidence of pcr is an understanding of the anatomical abnormality in the posterior capsule and perhaps the anterior vitreous and … The ideal stage of cataract development for surgery is immature. 2. This type of congenital cataract is not associated with systemic symptoms. Posterior polar cataract is a rare form of congenital cataract. To determine the rate of posterior capsular rupture (PCR) and assess the postoperative outcomes in patients of posterior polar cataract (PPC) undergoing phacoemulsification using a combination of "V" or "λ" nucleofractis and viscodissection.

Posterior polar cataract (PPC) is a unique form of congenital cataract, which results in defective distance and near vision and affects the patient's daily activities. This film showcases how modern bio-imaging (Optical coherence tomography) can help in pre-operative detection of a PC defect, and possibly increase safety during phacoemulsification . You also want to have the best possible results. Posterior polar cataract represents one of the uniquely challenging To prevent posterior capsular rupture, various measures have been suggested in the literature, including slow-motion phaco-emulsification with low aspiration flow rate, a low level of vacuum . The difficult ones are deep brown and extremely hard. Surgery in these patients can be challenging and should only be performed by highly experienced surgeons. Over the years, several technical modifications have been suggested to enhance safety and reduce posterior capsule rupture rates in these polar cataracts. Various genes have been implicated in the pathogenesis of PPC. Monovision: a review.

Dr. Devgan is an amazing surgeon and a wonderful human being! 1. Posterior polar cataract: Posterior polar cataracts are often associated with dehiscence of the central part of the posterior capsule. After completion of the continuous curvilinear capsulorrhexis (CCC), controlled hydrodelineation was used to separate the endonucleus from the epinuclear shell with limited viscodissection. Phacoemulsification was then carried out by making a "V" or lambda-shaped nucleofractis with the . Genetics. 1 depending on the clinical presentation, ppc can be divided into three categories: (1) ppc with. The 3 RCTs included in this review reported results for 21,531 total cataract surgeries with 707 total surgery-associated medical adverse events, including 61 hospitalizations and 3 deaths. Eyes were randomly assigned to two groups prior to emulsification: cortical viscodissection (Group 1) or non-viscodissection (Group 2). If the cataract is located in the center of your lens, it's called a nuclear cataract. Sporadic posterior polar cataracts are typically unilateral and associated with remnants of the tunica vasculosa lentis, an embryologic hyaloid structure that fails to regress. You can expect some slight pain and mild discomfort as well as general itching for a few days. Here's what you need to know to find the right doctor for you.

A controlled and gentle approach to phacoemulsification has proven to be the key factor for success in posterior polar cataracts. What are the causes of senile cataract? Cataract surgery in white or hypermature cataracts has been associated with increased risk for incomplete capsulorhexis, posterior capsule rupture, endothelial cell loss, and incision complications, such as wound burn. One study of more than 221,000 cataract surgery patients showed that 99.5% of the patients had no serious complications . The Study of Medical Testing for Cataract Surgery study team. 2012;119;891-899 Posterior polar cataract surgery is associated with an increased incidence of posterior capsular rupture. The success rate of optic capture also depends on the specific IOL design. In some cases, posterior capsulotomy may cause unexpected irregular posterior capsule rupture, which may cause the IOL to drop into the vitreous cavity ( Figure 7 ). N Engl J Med 2000;20:342:3:168-75. of high-viscosity sodium hyaluronate and double capsulorhexis allow the surgeon to achieve capsulorhexis with a high success rate. Due to the relatively lower success rate and higher recurrence rate for anterior capsulotomy, some doctors may choose posterior capsulotomy . Posterior polar cataract Sumeet Agrawal.
