Síndrome de contracción capsular bilateral / Bilateral capsule contraction syndrome

El síndrome de contracción capsular se describe como una reducción progresiva y acelerada del diámetro de la capsulorrexis y del saco capsular tras la extracción extracapsular del cristalino. Se reporta el caso de una paciente femenina, con antecedentes de miopía elevada, a quien se le realizó cirugía de catarata de ambos ojos sin complicaciones transquirúrgicas, y regresa con síndrome de contracción capsular bilateral al mes de operada. Se comenta la conducta seguida en ambos ojos(AU)

Capsule contraction syndrome is described as progressive, accelerated reduction in capsulorhexis and capsular bag diameter after extracapsular crystalline lens extraction. A case is presented of a female patient with a history of high myopia who underwent cataract surgery of both eyes without any intraoperative complication. One month after surgery the patient presents with bilateral capsule contraction syndrome. Comments are made on the clinical management of each eye(AU)

Clinical results of capsular sac relaxing surgery for capsular contraction syndrome / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To evaluate the clinical effects of capsular sac relaxing surgery(CBRS)on capsular contraction syndrome(CCS). <p>METHODS: This was a retrospective study, 8 patients(8 eyes)with CCS after cataract phacoemulsification. Eight eyes were treated by CBRS for a second continuous curvilinear capsularrhexis(CCC). Best corrected visual acuity(BCVA), diameter of the anterior capsule opening, absolute spherical equivalent and Intraocular astigmatism were observed before and 1wk after operation.<p>RESULTS: BCVA were significantly improved. The diameter of the anterior capsule opening were increased form(2.53±0.80)mm to(5.19±0.53)mm(<i>P</i><0.01). The intraocular astigmatism were decreased form(-2.22±0.51)D to(0.44±0.55)D(<i>P</i><0.01).<p>CONCLUSION: CBRS is an effective method for patients with CCS.

Comparison of endolaser or cryotherapy on capsule contraction syndrome after phaco - vitrectomy surgery for rhegmatogenous retinal detachment / 国际眼科杂志(Guoji Yanke Zazhi)

·AIM: To compare the influence of endolaser or cryotherapy on capsule contraction syndrome (CCS) following phaco - vitrectomy and intraocular lens implantation in patients with rhegmatogenous retinal detachment. ·METHODS: A total of 244 eyes were enrolled in this retrospective analysis. The surgical approach was standard vitrectomy combined with phacoemulsification and intraocular lens (IOL) implantation simultaneously. There were 198 eyes underwent endolaser and 46 eyes underwent cryotherapy during the surgery. The main outcome measures were postoperative clinical outcomes including anatomical position of retina, the capsules and the position of IOLs and best corrected visual acuity (BCVA) at 1d,1wk,1,2,3,6mo and 1a. ·RESULTS: There were 6 eyes (3.0%) of CCS occurred in endolaser group and 5 eyes (10.9%) of CCS occurred in cryotherapy group. The different procedures during the surgery were significantly associated with the incidence of CCS (odds ratio:0.256,P=0.021,95% Cl:0.075-0.880). ·CONCLUSION: Different procedures during phaco -vitrectomy surgery are significantly associated with the incidence of CCS. Endolaser is more beneficial than cryotherapy in preventing CCS following phaco -vitrectomy and intraocular lens implantation.

The Evaluation of Capsule Contraction Syndrome

As increasing demands for CCC (Continuous Curvilinear Capsulorhexis) fincreases, the incidence of capsule contraction syndrome is also increasing in cataract surgery. We tried to classify and treat this syndrome with 44 eyes who have capsule contraction. It is known that the basic mechanism of capsule contraction is fibrotic dysplasia of anterior capsule, and we found that capsular contraction can arise with glaucoma, diabetes mellitus, uveitis, retinitis pigmentosa, psuedoexfoliation syndrome and old aged group as ordered. It can also be frequently can be found in age 50 to 60. In order to decrease the complication of capsule contraction(IOL dislocation, retinal detachment, etc.), we incised the anterial capsule with Nd:Yag laser at the time of fibrotic change. For the case of weak zonules, we made a radial incision in the 12 o'clock direction after IOL insertion.

A Case of Capsule Contraction Syndrome following Continuous Curvilinear Capsulorhexis

Capsule contraction syndrome is severe constriction of the anterior capsular opening and equatorial capsular bag diameter after extracapsular cataract surgery. It is relatively common in patients with continuous curvilinear capsulorhexis, but rarely in can-opener capsulotomy or anterior radial capsular tears. It is due to capsular bag contraction from fibrous dysplasia of residual lens epithelial cells with weakened zonular resistance. We experienced a case of capsule contraction syndrome in a 72-year old woman with retinitis pigmentosa, who had phacoemulsification following an intact 5.0mm-continuous curvilinear capsulorhexis 4 months before. After successful YAG laser radial anterior relaxing capsulotomy, her visual acuity restored to 0.3, limited by cystoid macular edema.
