“…Der Patientenanteil, der angab, komplett auf eine Brille verzichten zu können, betrug ebenfalls 13%. Diese Zahlen sind vereinbar mit denen von Boerner et al [5] bei voller Monovision, in deren Patientenkollektiv postoperativ 11% stets und 14 % niemals eine Brille verwendeten. Finkelmann et al konnten eine komplette Brillenunabhängigkeit bei 25 % der Patienten nachweisen [23], was möglicherweise doch auf die höhere Anisometropie von im Mittel 1,16 dpt zurückzuführen ist.…”

Das menschliche Auge eines Erwachsenen ist nahezu kugelförmig, misst im Durchmesser etwa 24 mm und wiegt etwa 7,5 g. Die Wand des Augapfels besteht außen aus der weißen, bindegewebigen Lederhaut (Sklera), die dem Augapfel die Form gibt und von der Bindehaut bedeckt wird, und der klaren Hornhaut (Kornea). Letztere weist eine stärkere Krümmung auf. g max = g + gw g min = g -gn Da die Gegenstandsweite mit der Lage des Fernpunktes gleichgesetzt wird, muss für jede Gegenstandsentfernung eine entsprechende Brennweite berücksichtigt werden.

“…Das andere Auge wird mit einer IOL mit einer Brechkraft für die Nahkorrektur versehen. Die erste Erwähnung fand die pseudophake Monovision 1984 durch Boerner und Trasher [5]. Zur Anwendung der pseudophaken Monovision existieren nur wenige Publikationen, dennoch ist sie eine lang bekannte und genutzte Methode zur Brillenunabhängigkeit [6].…”

“…A prospective assessment of spectacle independence with patients in whom the refractive aims of monovision were successfully achieved found only 14% managed without glasses. 4 Myopic astigmatism inevitably limits distance acuity [5][6][7] which many surgeons would find unacceptable. A zoom principle accommodating IOL has been designed (BioComFold, Morcher, Stuttgart, Germany); unfortunately the anterior-posterior movement induced by accommodation is inadequate to produce the desired increase in effective power.…”

Aims To evaluate the functional effect of bilateral implantation of two different multifocal intraocular lenses (IOL) compared with the standard monofocal IOL. Methods Sixty-nine patients were recruited into a prospective, double-masked, randomised, controlled trial at a single hospital in the United Kingdom. Sixty completed follow-up; 16 implanted with monofocal IOLs, 29 with AMO 'ARRAY' multifocal IOLs and 15 with Storz 'TRUEVISTA' bifocal IOLs. Phacoemulsification and IOL implantation was performed to a standardised technique in both eyes within a 2-month period. The main outcome measures were distance and near visual acuity, depth of field and validated assessment of subjective function (TyPE questionnaire). Results Unaided distance acuity was good, and equivalent across the three groups. Corrected distance acuity was significantly lower in the bifocal group. Patients with multifocal and bifocal IOLs could read smaller absolute print size than those in the monofocal group (P = 0.05), but at a closer reading distance such that mean unaided near acuity was equal in the three groups. Corrected near acuity was significantly higher in the monofocal control group (P Ͻ 0.05). Depth of field was increased in multifocal (P = 0.06) and bifocal (P = 0.004) groups. Overall visual satisfaction was equal in the three groups, while near visual satisfaction was higher in the multifocal group than the monofocal (P = 0.04). Spectacle independence was not seen in the monofocal group, but was achieved in 28% of multifocal IOL patients and 33% of bifocal patients (P Ͻ 0.001). Adverse symptoms such as glare and haloes were significantly more bothersome with multifocal (not bifocal) IOLs than monofocals (P = 0.01). Conclusions Multifocal and bifocal IOLs improved unaided near vision performance, with around one in three patients becoming spectacle-independent. The main adverse effect was an increased incidence of subjective glare and haloes in the multifocal IOL group.

“…However, conventional IOLs have a single focus, which does not allow patients good, spectacle-free vision at both far and near distances. Various attempts to reestablish some degree of pseudoaccommodation after cataract surgery have been made, such as aiming for myopic astigmatism, 1 targeting 1 eye for myopia as in monovision, 2 or multifocal IOL implantation. 3 Substantial commercial investments have been made in the engineering, manufacturing, and clinical investigation of a wide variety of multifocal IOLs.…”

To evaluate visual results after bilateral implantation of multifocal intraocular lenses (IOLs) with asymmetrical light distribution for the far and near focus. Methods: Twenty-nine patients underwent bilateral implantation of silicone-optic, foldable, diffractive IOLs in a prospective, 2-center, noncontrolled interventional study. Each patient had a distant-dominant multifocal IOL implanted in 1 eye and a near-dominant multifocal IOL implanted in the fellow eye. Refractive and visual results, including contrast acuity and binocular visual function, were determined. Patients were questioned for postoperative spectacle usage. Results: Visual and contrast acuity in the dominant focus of either lens was superior to that in the nondomi-nant focus at 3.5 to 12 months postoperatively, ie, performance was best at distance for the distant-dominant and at near for the near-dominant lens. In binocular viewing, the monocular maximal results added up to an improved binocular visual performance. Binocular visual function was within normal limits. Eighty percent of patients reported no use of spectacles at any time postoperatively. Conclusions: Bilateral implantation of asymmetrical diffractive IOLs is an effective alternative for restoring simultaneous distance and near vision with a potential for improved contrast sensitivity compared with conventional multifocal IOLs.
