PURPOSE To establish the nationwide rate of postoperative endophthalmitis (PE) after cataract extraction (CE) and to study the relationship between PE and type of incision and other possible risk factors. DESIGN Prospective, multicenter, comparative, nonrandomized, observational study. PARTICIPANTS All cataract surgeries in Sweden performed from January(More)
The Swedish National Cataract Register (NCR) has been collecting data on cataract extractions in Sweden since 1992. This unique national database now contains data pertaining to more than 400 000 operations, representing 93.4% of all operations performed nationwide during 1992-2000. Clinic participation in the NCR is voluntary. Tests have shown NCR data to(More)
A transitory deposit of a fibrin-like material in the anterior chamber following extracapsular cataract extraction and intraocular lens (IOL) implantation is described. In two studies, one retrospective of 352 operations and one prospective of 189 operations, the fibrinoid reaction was observed in 17% and 11% of the eyes, respectively. The reaction appeared(More)
The differences between two careful applanation tonometries performed by one and by two observers, respectively, were compared. Two measurements by one observer differed by 2 mmHg or more in 8% of the pairs of measurements and by 3 mmHg or more in 2% of the pairs. One tonometry each by two observers differed by 2 mmHg or more 40% of the pairs of measurement(More)
PURPOSE To define the incidence of capsule complication and its risk factors in Sweden over an 8-year period. SETTING Fifty-two ophthalmic surgery units in Sweden. DESIGN Database study. METHODS Data were collected prospectively in the Swedish National Cataract Register (NCR) from 2002 through 2009. The NCR contains 97.3% of the total number of(More)
To study the prognosis of capsular glaucoma (102 eyes) as compared to simplex glaucoma (58 eyes), a retrospective comparison of the functional status of these diseases when first diagnosed and five years afterwards was made. At the first examination the capsular glaucoma eyes were on average more seriously damaged. After five years this tendency was more(More)
PURPOSE To investigate the epidemiology of postoperative endophthalmitis (POE) following cataract surgery in Sweden during a 3-year period, using the framework of the Swedish National Cataract Register. METHODS Clinically presumed cases of POE were reported in a prospective survey involving all Swedish ophthalmic surgical units except one. Data on results(More)
BACKGROUND The coexistence of cataract and age related macular degeneration (AMD) is not unusual, especially in the very elderly. The outcome of cataract surgery in these cases depends on the effect of AMD on vision. In this study the authors have compared the outcome of cataract patients with AMD to that of cataract patients with no vision threatening(More)
A total of 128 descendants from one large family with a history of hereditary macular degeneration (HMD) were examined with EOG. Of these, 42 were affected patients, 48 were healthy offsprings to affected parents, and 38 were normal controls. Affected subjects had a light peak/dark trough ratio smaller than 1.40. In the group of offspring of affected(More)
We studied the intraocular pressure (IOP) following extracapsular cataract extraction and posterior chamber lens implantation in 75 cases. Sodium hyaluronate (Healon) was used in all cases. In 40 cases, Healon was left in the eyes; in 35, the eyes were irrigated to remove Healon from the anterior chamber. When Healon was left in the eyes, 35% had an IOP(More)
