Posterior capsulorhexis in adult eyes with intact and clear capsules.

PURPOSE: To evaluate the feasibility and risks of primary posterior capsulorhexis. SETTING: Department of Ophthalmology, University Hospital of Liège, Belgium. METHODS: Retrospective analysis of 319 patients with cataracts who had phacoemulsification or manual extracapsular cataract extraction with a simultaneous circular posterior capsulorhexis between August 1993 and April 1994. The number of intraoperative complications and the number of postoperative complications that could be related to the posterior capsule opening were looked at. Fluorescein angiography was performed in a random sample of patients. RESULTS: Twelve intraoperative complications consisted of 5 irregular tears, 4 vitreous prolapses into the posterior capsulorhexis, and 3 vitreous prolapses into the anterior chamber; 11 occurred in eyes with positive posterior pressure. Postoperative complications consisted of 3 vitreous prolapses into the pupil and 1 retinal detachment. Two of the 3 late vitreous prolapses occurred in eyes in which the posterior capsulorhexis was larger than the intraocular lens (IOL) optic. The retinal detachment occurred in an eye with a 25.79 mm axial length. Fluorescein angiography of 49 cases revealed 3 with cystoid macular edema. CONCLUSIONS: Based on our results, we believe that primary posterior capsulorhexis can be a routine procedure during cataract surgery and IOL implantation in adults, except in cases of positive pressure. The diameter of the posterior capsulorhexis should be smaller than the diameter of the IOL optic.

[Posterior capsulorhexis in adults].

PURPOSE: To evaluate the feasibility and the risks of posterior capsulorhexis. MATERIAL AND METHODS: Retrospective analysis of 504 cases operated by phacoemulsification or manual extracapsular cataract extraction with a circular posterior capsulectomy. These cataracts were due to age or of unknown etiology. We analysed the intraoperative and postoperative complications. Fluorescein angiography was performed in a sample of unselected cases. RESULTS: The intraoperative complications consisted in 5 uncontrolled tearing and 7 prolapses of vitreous (4 of the 7 only in the posterior capsulectomy). Eleven of these twelve incidents occurred in case of positive posterior pressure. In the postoperative period, 3 additional prolapses of the vitreous in the pupil were observed; two of these capsulorhexis had been made larger than the optic of the intraocular lens. Three eyes with 25.79; 34.69 and 26.3 mm axial length presented a retinal detachment. Among 49 cases submitted to fluorescein angiography, 3 showed cystoid macular edema. CONCLUSIONS: Posterior capsulorhexis would be feasible in the cataract-implant surgery in adults, except in case of positive pressure. The diameter of the capsulorhexis has to be smaller to the diameter of the intraocular lens optic.

[Infectious complications of cataract-implant surgery].

We hold a review of essential notions concerning frequency, origin and signs of the infection that can follow an extra capsular cataract extraction with insertion of an intraocular lens. Prevention is briefly considered.

[Cataract extraction in uveitis].

UNLABELLED: As a frequent and important complication of uveitis, cataract poses a number of problems concerning surgical indications and techniques. This report discusses thirty patients operated for cataract as a complication of uveitis. The intervention was performed on eyes which had been quiet for six months. Sarcoidosis and Fuch's heterochromia were the principle etiologies. In some cases however, the etiology was unknown. Surgical methods and results are discussed. IN CONCLUSION: if particular indications are respected and if adequate postoperative anti-inflammatory treatment is provided, surgery for cataract secondary to uveitis has a relatively good prognosis.

[Capsulorhexis and manual extracapsular extraction].

Capsulorhexis is the best method of anterior capsulectomy. It is easier to perform a small capsulorhexis, suitable for phacoemulsification than a large capsulorhexis, suitable for a manual extracapsular extraction. We describe manoeuvres enabling the control of tearing the anterior capsule in such a way that the capsulorhexis will be adapted to the passage of the nucleus during the manual extracapsular extraction.

Glaucoma-lens ectopia-microspherophakia-stiffness-shortness (GEMSS) syndrome: a dominant disease with manifestations of Weill-Marchesani syndromes.

We report on a syndrome of progressive joint stiffness, glaucoma, and lens dislocation observed in three generations and compare it with two previous records of short stature, lens ectopia, and articular limitation. This family confirms the existence of a dominant Weill-Marchesani-like syndrome. We suggest that it could be related to the Moore-Federman syndrome. We coin the acronym GEMSS syndrome (Glaucoma, Ectopia, Microspherophakia, Stiff joints, Short stature) to distinguish this dominant Weill-Marchesani-like syndrome from the classic, recessively inherited syndrome.

[The value of pharyngo-esophageal manometry in the study of deglutition disorders].

Pharyngoesophageal manometry is an excellent tool for the study of pharyngeal swallowing disorders, and allows quantifying the various anomalies. The comparison of pre- and postoperative results allows better differentiation of the indications for myotomy or myectomy of the cricopharyngeal muscle. On the basis of a series of 10 cases with sufficient distance in time, the operation can be regarded as even more beneficial as the manometric anomalies are confined to the sole upper esophageal sphincter.

Two-year postoperative results of Galand lens implantation.

The Galand lens is a closed J-loop implant for capsular-bag fixation. We present a retrospective study of 214 eyes implanted with this lens. Eyes were examined at three months, six months, one year, and two years after surgery. Results indicate that 82.2% of eyes obtained a visual acuity of 20/40 or better at two years after implantation. If patients with other ocular pathology were excluded, the percentage of those whose visual acuity was 20/40 or better at two years was 93.7%. Although this implant avoids "spring action" within the capsular bag, the rate of dislocation into the posterior chamber was low (0.93% in this series). Early stability, before sealing of the capsular leaflets, was obtained by limiting the anterior capsulectomy to the pupillary area. No late zonular rupture was observed. Secondary posterior capsulotomy has been performed in 9.8% of the eyes.

Preliminary report on the rigid disc lens.

Theoretically, a circular and lenticular implant is the most appropriate for implantation in the capsular bag. Various prototypes have led to a single-piece model in polymethylmethacrylate with a bioconvex 7-mm optic and a 9-mm total diameter. This so-called disc lens has been implanted in 61 eyes. The longest follow-up is 18 months. Thus far, the clinical results are excellent. It appears that this 9-mm disc lens permits centration without acting as a spring in the capsular bag. A large mydriasis and the use of viscoelastic material are mandatory for inserting the rigid disc lens. A circular implant appears to be an advance in IOL design adapted to the capsular bag configuration. A greater number of cases and longer follow-up are necessary to evaluate the rigid disc lens.

[Magnetic resonance imaging of craniofacial pathology].

Effectiveness of nuclear magnetic resonance imaging (MRI) was compared with that of the CT scan in several cases involving different lesions: intracranial, base of skull, facial sinuses, parapharyngeal spaces. MRI provided excellent contrast in soft tissues with good detection of tumors and their limits, the condition of neighboring tissues and any local or regional tumor extension. Vessels were also visualized. It was not influenced by dental artefacts, and allowed three-dimensional sections to be obtained simply without manipulation of patients. In contrast, bone structures were analyzed less clearly than by the CT scan. Marked progress in MRI technical features and results obtained can be expected in the very near future.
