Intercapsular cataract surgery with lens epithelial cell removal. Part I: Without capsulorhexis.

Endocapsular phacoemulsification or intercapsular cataract extraction with lens epithelial cell removal using an ultrasound technique was performed on 30 eyes. The anterior capsule was not removed after posterior chamber intraocular lens implantation. After a mean follow-up period of 16.4 +/- 2.8 months, anterior capsule opacification was observed in six eyes, posterior synechias in six eyes, and shrinkage of the anterior capsule below the pupillary area, which resulted from the large opening needed for the intercapsular extraction, in 11 eyes. Other postoperative complications caused by lens epithelial cells such as posterior capsule opacification, intraocular lens dislocation, and fibrinous reaction did not occur. These results suggest it is necessary to remove the lens epithelial cells and the anterior capsule after posterior chamber lens implantation in intercapsular cataract extraction.

Capsulorhexis-related lacteocrumenasia.

Three patients who presented with a milky fluid in the space between the posterior surface of implanted intraocular lens (IOL) and the anterior surface of the distended posterior capsular bag are described. The patients were followed and were noted to have changes in their benign course after several years. The occurrence of this milky-fluid-filled capsular bag is extremely uncommon and is difficult to perceive if the observer is not looking for it.

Decentration of 5.1 mm intraocular lenses after continuous curvilinear capsulorhexis and in-the-bag fixation.

PURPOSE: To determine the incidence of decentration in eyes with 5.1 mm optic intraocular lenses (IOLs) and to assess the effect on vision. SETTING: Clinical Cataract Research Unit, Oxford Eye Hospital, Oxford, England. METHODS: Patients having phacoemulsification and small IOL implantation over 12 months were identified and invited for assessment. Intraocular lens decentration was measured geometrically using a modified, digital, retroillumination camera. The expected incidence of symptoms caused by decentration was estimated by determining the presence of an IOL edge within an artificial pupil overlaid on the digital image. RESULTS: In 13 eyes (20%), IOL decentration was more than 0.5 mm. Symptoms were expected in 38 patients (59%) but occurred in only 14 (22%). CONCLUSION: Decentration of the 5.1 mm optic IOL caused fewer clinical problems than anticipated, although the results raise concerns that such IOLs may be inappropriate in patients who need excellent vision in scotopic illumination.

Decentration of the posterior chamber lens implant: a comparison of capsulorhexis with endocapsular surgery.

The optical effect of posterior chamber lens decentration is a well-recognised complication of cataract surgery causing significant symptoms even with the larger-diameter implant optics available. In this paper we present the results of a study of implant decentration occurring with extracapsular surgery, in which we compared a group of patients with one tear in the anterior capsule with a second group with two tears in the anterior capsule. Our findings show that lens decentration is greater in those patients with two tears of the anterior capsule, and this difference is statistically significant.

[Theory and surgical technic of capsulorhexis].

Kapsulorhexis is a surgical technique for opening the anterior lens capsule with a circular, smooth-edged and continuous margin. Basically, the technique consists of a precisely controlled continuous capsular tear (rhexis), using only a sharp disposable needle with a bent tip. The method is reproducible, requires minimal instrumentation, is compatible with all current techniques of extracapsular surgery, and can be learned at no risk.

Secondary closure of posterior continuous circular capsulorhexis.

We examined the hypothesis that removing the center of the posterior capsule would reduce the risk for posterior opacification (PCO). We considered the prevalence of post-operative complications after PCCC like retinal detachment and cystoid macular edema, as found after Nd-YAG laser capsulotomy.
