Progression of nonproliferative diabetic retinopathy following cataract extraction.

Eight patients experienced progression of nonproliferative diabetic retinopathy following cataract extraction. Six patients underwent an uncomplicated extracapsular cataract extraction with placement of a posterior chamber intraocular lens, and in two patients, surgery was complicated by vitreous loss. In each case the retinopathy progressed to a severe exudative form of diabetic macular edema, characterized by diffuse retinal thickening and fluorescein leakage with increased dot and blot hemorrhages and lipid deposition. In all patients, clinically significant macular edema developed in the eye that had been operated on, and six patients received laser photocoagulation for this condition. Final visual acuity was worse than preoperative visual acuity in six of eight patients, and it was unchanged in two of six patients. No patient achieved a visual acuity better than 20/50. The fellow eyes, which were not operated on, remained stable during the follow-up period.

Cataract extraction combined with trabeculotomy.

Eyes with glaucomatous damage as well as eyes showing a clear elevation of intraocular pressure (IOP) to levels above normal frequently develop a permanent elevation of IOP after phacoemulsification or extracapsular cataract extraction, whereas the pressure in normal eyes usually decreases. In eyes with glaucomatous damage, we therefore combined cataract extraction with an antiglaucomatous operation, especially if a moderate pressure elevation was present: trabeculotomy and cataract extraction were performed in the same procedure. A corneal incision was used for phacoemulsification or extracapsular cataract extraction. The effects of the operation on the IOP and the visual acuity as well as the incidence of postoperative complications were investigated. In 44 operated eyes, the combination of cataract extraction and trabeculotomy proved to result in few complications and had a sufficient pressure-decreasing effect that continued throughout the 18 months of postoperative follow-up.

Cataract extraction in spontaneous low-flow indirect dural bilateral carotid cavernous fistula.

BACKGROUND: Cataract extraction in a carotid cavernous fistula can cause multiple intraoperative complications during surgery. METHODS: This was a case of bilateral, indirect, carotid, cavernous fistula, type D. The patient developed cataract and visual deterioration in both eyes. We present the difficulties we encountered during extracapsular cataract surgery on one of the eyes. RESULTS: Cataract extraction was done successfully. A self-sealing scleral incision was made. An intraocular lens was implanted. CONCLUSION: Cataract extraction can be done in carotid cavernous fistulas; however, the surgeon should be extremely cautious during the surgery.

Neovascular glaucoma after intracapsular and extracapsular cataract extraction in diabetic patients.

A retrospective study of the rate of development of neovascular glaucoma after cataract extraction in 242 eyes of 186 diabetic patients identified neovascular glaucoma in 13 of 146 eyes (8.9%) after intracapsular extraction, in two of 17 eyes (11.8%) after extracapsular extraction with primary capsulotomy, and in zero of 53 eyes after extracapsular extraction without capsulotomy. The incidence of neovascular glaucoma was significantly lower in patients who underwent extracapsular extraction with preservation of an intact posterior capsule than in those undergoing intracapsular cataract extraction (P less than .01) or extracapsular cataract extraction with primary capsulotomy (P less than .05).

National outcomes of cataract extraction. I. Retinal detachment after inpatient surgery.

Rehospitalization for retinal detachment (RD) was studied in 338,141 Medicare beneficiaries older than 65 years of age who were undergoing inpatient cataract extraction in 1984. Extracapsular cataract extraction (ECCE) was performed in 60% of patients, intracapsular cataract extraction (ICCE) in 31%, and phacoemulsification in 9%. The risk of rehospitalization for RD within 4 years of ICCE was 1.55% over 1.5 times the risk associated with ECCE (0.9%). The risk of RD after phacoemulsification was 1.17%. Cataract surgery accompanied by anterior vitrectomy was associated with a 5.0%, likelihood of RD at 4 years, which is 4.5 times greater than that for cataract surgery alone (1.12%). White patients were 1.7 times more likely to be rehospitalized for RD than were black patients (1.15% versus 0.67%; P less than 0.001). In both races, younger patients were more likely to be rehospitalized for RD than were older patients (P less than 0.001). While the increased rate of RD after ICCE versus ECCE confirms previously held clinical beliefs, the increase in the risk following phacoemulsification (P less than 0.0001) has not been reported previously.

Cataract extraction in the diabetic eye after vitrectomy.

We examined 289 phakic, diabetic eyes for evidence of cataract formation after a successful vitrectomy. Of 289 eyes, 107 (37%) developed or had significant progression of a cataract over a follow-up period of 16 to 108 months. Postvitrectomy hemorrhage and vitreous lavage were associated with an increased rate of cataract formation. Of the 107 eyes, 33 (31%) subsequently had cataract extraction, with 24 eyes (73%) treated by extracapsular cataract extraction and nine eyes (27%) with intracapsular surgery. A posterior chamber lens was used in 11 of the 24 eyes that underwent extracapsular surgery. Of the 33 eyes, 31 (94%) had improved visual acuity after cataract extraction. Intraoperative and postoperative complications were minimal and did not result in permanent reduction of vision. Intraocular lenses were well tolerated in the 11 patients in whom they were used.

Exposure to allopurinol and the risk of cataract extraction in elderly patients.

OBJECTIVE: To determine whether exposure to allopurinol is associated with an increased risk of cataract extraction in elderly patients. METHODS: We conducted a case-control study using data from the Quebec universal health insurance program for all elderly patients. The 3677 cases were patients with a cataract extraction between 1992 and 1994. The 21,868 controls were randomly selected among patients not diagnosed with cataract and matched to cases on the date of the extraction. We determined the odds ratio of cataract extraction according to the cumulative dose and duration of allopurinol use relative to nonusers, using conditional logistic regression analysis. The analysis was adjusted for the effects of age, sex, diabetes mellitus, hypertension, glaucoma, and ophthalmic and oral corticosteroid exposure. RESULTS: A cumulative dose of allopurinol of more than 400 g or a duration of use of longer than 3 years were associated with an increased risk of cataract extraction, with odds ratios of 1.82 (95% confidence interval [CI], 1.18-2.80) and 1.53 (95% CI, 1.12-2.08), respectively. No increase in risk was observed for lower cumulative doses or shorter exposure periods. CONCLUSION: Long-term administration of allopurinol increases the risk of cataract extraction in elderly patients.

Apraclonidine and early postoperative intraocular hypertension after cataract extraction.

The efficacy of topical 1% apraclonidine in controlling early postoperative IOP rise after cataract extraction was evaluated. Topical 1% apraclonidine was applied to 20 patients who underwent extracapsular cataract extraction with posterior intraocular lens implantation. On another 20 patients, who acted as control group a placebo (artificial tears) was given. The IOP was measured before preoperative medication and postoperatively at 6, 12 and 24 h, using the Perkins hand-held applanation tonometer. In the control group, 9 patients (45%) developed intraocular hypertension and in the treated group only 2 (10%) showed hypertension, but with short duration and a moderate IOP rise. The difference in frequency of intraocular hypertension between the groups was statistically significant (p less than 0.02). The statistical analysis showed that the postoperative IOP of operated treated eyes was significantly smaller than the IOP of operated control eyes. Furthermore, the postoperative IOP and the initial IOP did not differ statistically. The results of this study demonstrate the efficacy of topical apraclonidine 1% in controlling the early and transient intraocular hypertension following cataract extraction.

National outcomes of cataract extraction. III. Corneal edema and transplant following inpatient surgery.

We analyzed the likelihood of rehospitalization for corneal edema or corneal transplantation in all 338,141 Medicare beneficiaries older than 65 years who were admitted to US hospitals for cataract extraction in 1984. The rate of rehospitalization for corneal edema or transplant within 4 years of intracapsular cataract extraction was 1.4%, almost twice the rate associated with extracapsular extraction (0.63%) or phacoemulsification (0.62%; P less than .0001). No significant difference in the rate of corneal transplantation was detected between those undergoing extracapsular cataract extraction and those undergoing phacoemulsification. Among patients who had intracapsular cataract extraction, those who underwent concurrent intraocular lens implantation surgery had a higher rate of rehospitalization for corneal edema or transplantation than those who did not (1.11% vs 0.86%; P = .0003). However, this difference is only manifest starting at about 3 years after surgery. Among patients who underwent extracapsular cataract extraction and phacoemulsification, however, those who underwent intraocular lens implantation during surgery had a lower rate of corneal edema or transplantation than those who did not (0.47% vs 0.74%; P less than .0001). This difference was seen almost immediately after surgery. Cataract surgery accompanied by anterior vitrectomy was associated with a threefold increase in the 4-year rate of corneal edema or transplantation compared with cataract surgery alone (2.42% vs 0.87%; P less than .0001).

Persisting corneal oedema following intracapsular cataract extraction.

PURPOSE: The purpose of this study was to reveal the frequency of persisting corneal oedema following intracapsular cataract extraction and at the same time to examine whether the survival rate after penetrating keratoplasty due to this diagnosis differs from the survival rate following penetrating keratoplasty due to primary Fuchs' endothelial dystrophy. METHODS AND MATERIAL: A series of 2455 eyes underwent intracapsular cataract extraction between January 1, 1986 and December 31, 1988, at the Department of Ophthalmology, Arhus University Hospital. The medical files were examined to study the frequency of persisting corneal oedema. Patients with persisting corneal oedema were offered penetrating keratoplasty and the survival rate following this procedure was calculated. RESULTS: The frequency of pseudophakic persisting corneal oedema was 5.3% in the group of patients who underwent intracapsular cataract extraction. The survival of the following corneal transplantation was 54% after 2 years of follow-up. This is a low survival rate compared to the survival rate in primary Fuchs' endothelial dystrophy, but there is a similarity to this disease in a development of a slowly progressive oedema in 17% compared to 13% in primary Fuchs' endothelial dystrophy. CONCLUSION: 5.3% of a group of patients who underwent intracapsular cataract extraction developed persisting corneal oedema within a 5 to 7-year follow-up period. When these patients underwent penetrating keratoplasty the survival rate of the graft was 54% after 2 years of follow-up.

[Personal experience with modern extracapsular cataract extraction].

In the group of 42 eyes with extracapsular cataract extraction the postoperative results were very favourable differing conditions. There did not occur any more serious postoperative complications. Authors verified that for a skillful ophthalmic surgeon this operation is easily performed, on the other hand many of them have to overcome some accustomed aversion and to use at present time the needed extracapsular extraction, in spite of the previous routinely used intracapsular technique, which was successfully performed for many years. Present trend of extracapsular cataract extractions is based on the aim to decrease the number of the postoperative complications and to make possible the implantation of the intraocular lenses into the posterior chamber of the eye.

Penetrating keratoplasty combined with extracapsular cataract extraction.

In my previous prospective study of 132 eyes, the incidence of clinically significant cystoid macular edema was 42% in aphakic penetrating keratoplasty, 33% in combined keratoplasty and cataract extraction with vitrectomy, and only 4% in combined keratoplasty and cataract extraction without vitrectomy. In the present study we added 26 aphakic and 11 pseudophakic keratoplasties and 17 procedures combining keratoplasty with extracapsular cataract extraction. Grafts were clear in 94% of patients, and 43% had visual acuity of 20/40 or better. Clinically significant cystoid macular edema occurred in 35% of aphakic and 27% of pseudophakic keratoplasties. Cystoid macular edema did not occur in combined keratoplasty and extracapsular cataract extraction.

[Corneal astigmatism after tunnel incision for cataract extraction].

PURPOSE: To evaluate the development of astigmatism after cataract extraction depending on the kind of incision MATERIAL AND METHODS: Astigmatism was examined in 107 eyes of 92 patients, who underwent cataract extraction, mostly with IOL's implantation. In 52 eyes phacoemulsification with tunnel incision, measuring 5 mm in 27 and 8 mm in 25, was performed. In the control group of 55 eyes incision with scleral flap measured 2/5 of the corneal circumference. In cases with 5 mm incisions no sutures were used, in 8 mm incisions wounds were closed with single sutures and in control group the double continuous sutures were applied. Astigmatism was measured in two days, one week, four weeks and 3 months after surgery. RESULTS: Post-operative astigmatism decreased gradually and after 3 months was average 0.14 D in the eyes without sutures, 0.68 D in those with single ones and 1.78 D in the control group.

Anterior hyaloidal fibrovascular proliferation after extracapsular cataract extraction in diabetic eyes.

Four patients with proliferative diabetic retinopathy developed anterior hyaloidal fibrovascular proliferation after extracapsular cataract extraction and posterior chamber lens implantation. This complication of cataract extraction has been described after vitrectomy in diabetic eyes. Risk factors for this entity after extracapsular cataract extraction include proliferative diabetic retinopathy, iris neovascularization, and anterior ischemic retina. Anterior hyaloidal fibrovascular proliferation was observed an average of 12 months postoperatively and affected vision in one of four patients. No progression was seen within an average of six months of follow-up, and no complications such as traction retinal detachment and vitreous hemorrhage developed.

Otago Glaucoma Surgery Outcome Study: long term results of cataract extraction combined with Molteno implant insertion or trabeculectomy in primary glaucoma.

BACKGROUND/AIMS: To describe the long term results of cases of cataract extraction combined with either Molteno implant insertion or trabeculectomy for primary open angle glaucoma. METHODS: This prospective case series followed cases which had cataract extraction and Molteno implant insertion (45 eyes) or trabeculectomy (94 eyes) followed up for a mean of 5.3 years and 3.9 years respectively. RESULTS: Cataract extraction and Molteno implant insertion or trabeculectomy controlled the intraocular pressure at 21 mmHg or less with a probability of 1.00 (95% CI 0.93 to 1.00) at 10 years or more after operation and 0.94 (95% CI 0.89 to 0.99) and 0.73 (95% CI 0.46 to 0.99) at five and 10 years after operation respectively. CONCLUSIONS: Cataract extraction combined with insertion of Molteno implants or trabeculectomy controlled the intraocular pressure in 100% (45/45) and 94% (88/94) of cases respectively.

Corneal trauma in intracapsular and extracapsular cataract extraction with lens implantation.

We examined the central corneal endothelium before and eight weeks after cataract extraction and lens implantation in 99 consecutive intracapsular and extracapsular extractions each. There was no statistically significant different between the mean endothelial cell loss of 17.1% in the intracapsular group and 13.6% in the extracapsular group. The variation in individual endothelial cell sizes was less postoperatively in the extracapsular extractions. The central corneal thickness were the same in the two groups. There was no statistically significant difference between the mean endothelial cell loss of 17.0% in 24 posterior chamber lenses and 12.1% in 69 transiridectomy clip lenses, both with extracapsular cataract extraction. When combined with intraocular lens implantation, extracapsular cataract extraction, even when performed by surgeons inexperienced with extracapsular techniques, caused no greater corneal endothelial damage than intracapsular extraction.

[Effectiveness of the use of proteolytic enzymes in extracapsular cataract extraction].

Experimental and clinical study of lekozim and collalysine proteolytic enzymes efficacies in extracapsular cataract extraction was carried out. Local application of these agents in irrigation aspiration of the cortical mass from the capsule sac equator not only simplified the technique of the most intricate stage of surgery, but also proved to be a sufficiently effective means of secondary cataract prevention. A follow-up of up to 3 years has shown secondary cataract development in 5 percent of patients after extracapsular cataract extraction administered lekozim, in 10 percent of those administered collalysine, and in 17.5 percent of cases with mechanical vacuum extraction. Lekozim and collalysine may be used in all the cases when extracapsular cataract extraction is possible.
