[Is assessment of complications following intra- and extracapsular cataract extraction with lens implantation biased?].

Extracapsular Cataract extraction with implantation of a posterior chamber lens has become the standard procedure in cataract surgery. Excellent results are accomplished with this method. It is remarkable, however, that there are scarcely any data about the rate of complications, e.g. capsular fibrosis with the necessity of YAG-laser-capsulotomy and its sequelae. Similarly, data on decentration of the lens, its consequences and correction are rare. The arguments against ICCE with implantation of a Choyce-Mark-IX anterior chamber lens like higher rate of retinal detachment, cystoid macular edema and corneal decompensation can not be confirmed by us on the basis of prospective clinical studies. With an appropriate operation technique equivalent results can be obtained as in ECCE. The debates about cataract surgery are carried out more on the basis of clinical impressions than on the basis of thorough scientific data. Surgery should not be a matter of "trends".

Cataract extraction and intraocular lens implantation after fistulizing glaucoma surgery.

Cataract extraction with implantation of an intraocular lens was performed in 33 patients who had previously undergone fistulizing glaucoma surgery. A functioning filtering bleb and normal intraocular pressure were important preoperative criteria, however success depended largely upon enhanced postoperative aqueous outflow. Bleb failure following cataract surgery may be caused by prolonged intraoperative hypotony, vitreous or intraocular lens occlusion of the filtering site, or the presence of postoperative inflammatory components in the aqueous. Extracapsular cataract extraction was the most satisfactory technique. Most cases received prepupillary iridocapsular lenses.

[Stereopsis of the patients after cataract extraction and intraocular lens implantation].

OBJECTIVE: To understand the stereopsis of the patients after cataract extractation and intraocular lens implantation and the related factors. METHODS: In this study were examined the stereopsis of 30 patients who had undergone cataract extraction and intraocular lens implantation and whose post-operative vision acuity measurements were 0.5 or higher. RESULTS: These patients' steroacuity, anisometropia, aniseikonia and scotoma were: 407.67" +/- 390.19", 1.53D +/- 1.96D, 3.93% +/- 3.51%, 3.17" +/- 1.98" respectively. There was no significant correlation between steroacuity anisometropia and aniseikonia. There was siganificant positive correlation between steroacuity and scotoma. CONCLUSIONS: Intraocular lens implantation may ameliorate anisometropia and aniseikonia of the patients after cataract extraction and reduce the damage to stereopsis.

The outcome of the functioning filter after subsequent cataract extraction.

OBJECTIVE: To evaluate and compare the outcome of functioning filtration surgery followed by cataract surgery with posterior intraocular lens implantation by both phacoemulsification and extracapsular cataract extraction (ECCE) techniques in glaucomatous eyes. PATIENTS AND METHODS: We retrospectively evaluated the clinical course of 77 eyes (68 patients) that after successful trabeculectomy, underwent cataract surgery by either phacoemulsification or ECCE techniques. We determined the frequency of partial and absolute failure following cataract surgery by either phacoemulsification or ECCE in eyes with functioning trabeculectomies. Partial failure of intraocular pressure (IOP), control after cataract extraction was defined as the need for an increased number of antiglaucoma medications or argon laser trabeculoplasty to maintain IOP < or =21mm Hg. Complete failure of IOP control after cataract surgery was defined as an IOP >21 mm Hg on at least two consecutive measurements one or more weeks apart or the performance of additional filtration surgery. Failure rates were calculated using the Kaplan-Meier actuarial method. Failure rates between phacoemulsification and ECCE subgroups were compared using the log rank test. RESULTS: The probability of partial failure by the third postoperative year after cataract surgery was 39.5% in the phacoemulsification subgroup and 37.3% in the ECCE subgroup. This small difference is not statistically significant (P = 0.48). The probability of complete failure by the fourth postoperative year after cataract surgery was 12.0% in the phacoemulsification subgroup and 12.5% in the ECCE subgroup. This difference is also not statistically significant (P = 0.77). At the 6-month follow-up visit, visual acuity of both groups improved one or more lines in 87.0% of patients, and worsened one or more lines in 3.9% of patients. Sixty-one percent achieved visual acuity of 20/40 or better. The most frequent complication was posterior capsular opacification requiring laser capsulotomy that occurred in 31.2% of patients. CONCLUSION: Cataract extraction by either phacoemulsification or ECCE following trabeculectomy surgery may be associated with a partial loss of the previously functioning filter and the need for more antiglaucoma medications to control IOP.

Retinal detachment following intracapsular and extracapsular cataract extraction. A comparative, retrospective follow-up study.

In a retrospective study we reviewed the post-operative incidence of retinal detachment in a consecutive series of 762 eyes operated on with intracapsular cataract extraction and a consecutive series of 1351 eyes operated on with extracapsular cataract extraction. Follow-up time was 2 1/2-4 1/2 years in both series. The incidence of retinal detachment was 0.79% after intracapsular cataract extraction and 0.44% after extracapsular cataract extraction. The difference was not statistically significant. Age below 70 years was not statistically significantly correlated to retinal detachment.

Phacoemulsification cataract extraction and posterior chamber lens implantation in patients with uveitis.

PURPOSE: This study reports outcomes of phacoemulsification cataract extraction and posterior chamber intraocular lens implantation within the capsular bag in patients with uveitis. METHODS: We retrospectively reviewed the charts of 32 patients (39 eyes) with uveitis who underwent phacoemulsification cataract extraction and posterior chamber intraocular lens implantation by two surgeons at The Cleveland Clinic Foundation from January 1990 to June 1998. Patients with less than 3 months of follow-up were excluded. RESULTS: Diagnoses of uveitis included idiopathic (15 eyes), sarcoidosis (10 eyes), pars planitis (four eyes), CMV retinitis (two eyes), Fuchs heterochromic iridocyclitis (two eyes), syphilis (two eyes), and one eye each of tuberculosis, Crohn's disease, HLA-B27 associated, and acute retinal necrosis. Average follow-up was 20 months (range, 3 to 63 months). Best-corrected visual acuity improved in 37 eyes (95%). Average improvement was 4 +/- 3 Snellen acuity lines (range, 1 to 10 lines). Thirty-four eyes (87%) attained final visual acuity better than or equal to 20/40. Visual loss occurred in one eye (3%) with CMV retinitis. No improvement in visual acuity was seen in one eye (3%) that developed a retinal pigment epithelial detachment. Posterior capsule opacification occurred in 24 eyes (62%), 12 of which required Nd:YAG capsulotomy (31%). Other postoperative complications included recurrence of uveitis (41%), cystoid macular edema (33%), epiretinal membrane formation (15%), and posterior synechiae (8%). CONCLUSIONS: Phacoemulsification cataract extraction with posterior chamber intraocular lens implantation is safe in patients with uveitis. The incidences of recurrence of uveitis, cystoid macular edema, epiretinal membrane, and posterior synechiae were lower than those reported previously for extracapsular cataract extraction.

Cataract extraction in eyes with congenital colobomata.

Cataract surgery was performed in six eyes of four patients with typical colobomata of the iris, choroid, and retina. Contrary to previous reports of poor surgical results in these eyes, we saw no surgical or postoperative complications. Final visual acuity was excellent in four eyes. The other two had preexisting amblyopia. Most previous reports describe outmoded extracapsular techniques or contemporary intracapsular cataract extraction, all without an intraocular lens. Five of the six eyes in this study had modern cataract surgery--phacoemulsification with a posterior chamber lens placed in the capsular bag.

Retinal detachment after cataract extraction and refractive lens exchange in highly myopic patients.

PURPOSE: To assess the refractive effects and incidence of postoperative complications in patients with high myopia after cataract extraction. SETTING: University Eye Clinic, Trieste, Italy. METHODS: This noncomparative retrospective study comprised all eyes (N = 388) having cataract extraction and implantation of an intraocular lens with a power less than 11.0 diopters (D) between 1986 and 1999. The preoperative and postoperative refractions; preoperative, postoperative, and final best corrected visual acuity (BCVA); and postoperative complications were analyzed. The mean follow-up was 47.16 months +/- 32.83 (SD) (range 8 to 146 months). RESULTS: Phacoemulsification was performed in 237 eyes, extracapsular cataract extraction in 147 eyes, and intracapsular cataract extraction in 4 eyes. The mean preoperative BCVA was 0.20 +/- 0.21 and the mean postoperative BCVA, 0.58 +/- 0.32. At the final evaluation, the mean BCVA was 0.50 +/- 0.33. The mean refraction was -15.95 +/- 5.86 D preoperatively and -2.00 +/- 1.62 D postoperatively. One eye (0.26%) developed a retinal detachment postoperatively. Of the 127 eyes (32.73%) having a neodymium:YAG laser capsulotomy for posterior capsule opacification, 1 had a macular retinal hole. Posterior detachment of the vitreous occurred in 78.6% of cases. Peripheral retinal photocoagulation was required in 8 cases postoperatively. CONCLUSION: Refractive lens exchange led to good functional results and a low incidence of postoperative complications and can thus be regarded as a viable technique to correct high myopia associated with cataract. However, further study is required before it can be routinely recommended for the correction of high myopia in eyes with a transparent crystalline lens.

Current practice of cataract extraction and anaesthesia.

A questionnaire regarding preferred methods of cataract extraction and anaesthesia was sent to 456 consultant ophthalmologists in England and Wales. Replies were received from 86% (n = 392), 83% (n = 380) having completed the questionnaire in full. The most frequently employed surgical approach was non-automated extracapsular cataract extraction. Only 2% of surgeons (n = 8) used phacoemulsification routinely and 2% (n = 7) used intracapsular extraction. Intraocular lens implantation was the standard practice of 99% of surgeons (n = 376). There has been a dramatic increase in the popularity of local anaesthesia, which was employed routinely (in more than three-quarters of their cases) by 20% of surgeons (n = 76). Retrobulbar infiltration remains the most common method of administration. Sedation was given routinely by 45% of surgeons (n = 171) when using local anaesthesia. Medical contraindications and patient preference were considered the most important reasons for selecting local anaesthesia rather than general. The exclusive use of general anaesthesia in cataract surgery appears to be diminishing.

Extracapsular cataract extraction: prognosis and complications with and without posterior-chamber lens implantations.

Four-hundred-and-sixteen eyes that underwent cataract extraction over six years were analyzed. Extracapsular cataract extraction with posterior-chamber intraocular lens implantation (PCIOL) was performed in 186 eyes and extracapsular cataract extraction (ECCE) alone was performed in 230 eyes. The complications and visual acuity were compared in the two groups. The PCIOL group showed a low incidence of postoperative complications. In addition, there were no cases of corneal edema; retinal detachment occurred in 1.33%; cystoid macular edema occurred in 2.67%; and visual acuity recovered to 20/40 or better in 96.67% of eyes. The incidence of complications in the ECCE group was slightly higher.

Combined cataract extraction and glaucoma surgery.

An approach to the surgical management of eyes with concomitant cataract and glaucoma is outlined, and the author's experience in 73 consecutive cases is described. Cataract extraction alone is recommended when glaucomatous damage is minimal, and the intraocular pressure is controlled with a low-dose, well-tolerated medical regimen. When the glaucoma is uncontrolled on maximum tolerable medical therapy and poses an immediate threat to vision, a two-stage procedure of filtering surgery with subsequent cataract extraction is preferred. Between these two extremes of glaucoma control are those cases for which a combined operation is felt to be indicated, especially when cataract surgery is planned in an eye with borderline glaucoma control and/or moderate to advanced glaucomatous damage. The preferred combined approach is cataract extraction with a guarded filtering procedure, and a simplified technique to accomplish this is described.

Posterior capsule opacification in extracapsular cataract extraction and the triple procedure: a comparative study.

We retrospectively studied 330 consecutive cases, comparing the incidence of posterior capsule opacification after 279 extracapsular cataract extractions (ECCEs) or phacoemulsifications and posterior chamber intraocular lens (PC-IOL) insertions, with the incidence of opacification following 51 combined corneal transplantations, cataract extractions, and PC-IOL insertions (ie, triple procedures). Opacification developed less frequently following the triple procedure than after cataract extraction alone (9.8% vs 36.2%, respectively; P < .001). Opacification also developed later following the triple procedure. The mean length of time before capsular opacification after cataract extraction alone was 24.3 months, while a mean of 45.6 months elapsed before opacification developed after the triple procedures (P < .05). Delineation of the mechanisms contributing to these outcome differences may provide a means of reducing the incidence of or preventing posterior capsule opacification after cataract surgery.

Bilateral cataract extractions in one session. A report on 134 consecutive cases.

One hundred and thirty-four bilateral cataract extractions are discussed. Intra-operative and short-term postoperative complications are compared with those of unilateral cataract extraction. Bilateral cataracts may be extracted in one session for socio-economic reasons, since the incidence of bilateral postoperative endophthalmitis is low.

Pars plana vitrectomy for macular holes combined with cataract extraction and lens implantation.

BACKGROUND AND OBJECTIVE: To evaluate the safety and efficacy of cataract extraction and lens implantation at the time of pars plana vitrectomy (PPV) for macular hole (MH) repair. MATERIALS AND METHODS: A retrospective study was conducted of 21 eyes that had PPV for MH combined with cataract extraction and lens implantation. Visual acuities (VA) were followed and complications noted. RESULTS: Of 21 eyes, successful anatomic closure was achieved in 16 (76.2%), and 13 (62.0%) improved in VA by at least 2 Snellen lines. Few complications occurred. CONCLUSION: Procedures that combine PPV for MH with cataract extraction and lens implantation decrease the need for future ophthalmic surgery, allow for clearer intraoperative visualization, and facilitate visual rehabilitation. This combined procedure is a relatively safe and effective alternative to separate pars plana and cataract surgeries.

Extracapsular cataract extraction in diabetic eyes. The role of YAG laser capsulotomy.

Cataract surgery may exacerbate preexisting diabetic retinopathy. Especially diabetics with active retinal neovascularisation are at high risk of rubeosis iridis after intracapsular cataract extraction. Thirty-five eyes previously treated with panretinal photocoagulation underwent extracapsular cataract extraction with posterior chamber lens implantation. Twenty-eight eyes with retinal neovascularisation required further Argon laser PRP after surgery. Fourteen eyes required YAG-laser capsulotomy. From the group of eyes without YAG-laser capsulotomy none developed neovascular glaucoma. From the YAG laser capsulotomy group six eyes developed rubeosis iridis and neovascular glaucoma. Our results indicate that eyes in which PRP has been performed, have an excellent prognosis after ECCE with posterior chamber lens implantation only if YAG Laser posterior capsulotomy is not performed.

A prospective study of alcohol consumption and cataract extraction among U.S. women.

PURPOSE: Alcohol consumption has been implicated in the pathogenesis of cataract in some, but not all analytic studies. To date, no prospective analysis of the relationship between alcohol consumption and cataract has been conducted in women. METHODS: We examined the association between alcohol consumption and cataract extraction in a prospective cohort of female registered nurses. In 1980, 50,461 women were included and others were added as they became 45 years of age for a total of 77,466 women. Information on alcohol consumption and incidence of senile cataract extraction was ascertained during 12 years of follow-up with biennial questionnaires. RESULTS: We observed 1468 cases of cataract extraction in 761,036 person-years of follow-up. Compared to nondrinkers, those consuming alcohol were not at increased risk of cataract, even up to 25 grams or more per day (2 or more drinks). Results remained unchanged after controlling for cataract risk factors including cigarette smoking, body mass index, and diabetes. When risk was examined for specific cataract subtypes only, those in the highest category of consumption had a multivariate relative risk of 1.10 for nuclear cataracts and 1.50 for posterior subcapsular cataracts only. CONCLUSIONS: These prospective data suggest that there is no substantial overall increased risk of senile cataract due to alcohol intake. The possibility that alcohol consumption leads to a modest increased risk of posterior subcapsular type opacities requiring extraction merits further exploration.

Prevalence of circulatory disease among patients undergoing intracapsular cataract extraction.

Prevalences of 15 circulatory diagnoses were investigated for 113,242 patients undergoing intracapsular cataract extraction and 67,052 reference patients discharged from a sample of North American hospitals during 1979. After controlling for distributional differences in age (nine categories between 45 and 89 years), sex, and race (white v nonwhite), seven of the 15 diagnoses occurred with sufficient frequency to allow age-, sex-, and race-adjusted analysis. All seven of those diagnoses were found to have statistically significant differences in prevalences between the two procedure groups. Only benign hypertension was found to be more prevalent among patients undergoing cataract extraction regardless of age, sex, or race. The remaining six diagnoses all had a pattern of elevated prevalence among younger patients undergoing cataract extraction changing to elevated prevalence among other surgical patients at older ages.

Fibrosis adjacent to the anterior lens capsule after extracapsular cataract extraction.

Fibrosis, contraction and opacification of the posterior lens capsule after extracapsular cataract extraction, is a frequent complication following cataract surgery. In these cases, cellular proliferation occurs along an intact posterior capsule. We report a case of fibrosis adjacent to the anterior lens capsule, where cellular proliferations and collagen production completely sealed the anterior capsulotomy three months after a routine extracapsular cataract extraction with implantation of a posterior chamber lens. The fibrosis led to contraction of the remainder of the anterior capsule, significantly reducing vision. Examination of the excised material by light and electron microscopy, and immunohistochemistry, revealed cells with features compatible with fibrocytes that did not stain positive for cytokeratin. The cells were situated in a dense collagen matrix. An anterior capsulotomy that is too small prevents sufficient removal of lens epithelium, and may be a risk factor for this complication.
