Zusammenfassung

Hintergrund

Ziel der vorliegenden Studie ist die Evaluierung des klinischen Verhaltens der hydrophilen Acryllinse ACR6D SE (Corneal®) mit scharfer umlaufender Kante und 10° angulierten Haptiken.

Setting

Universitätsklinik für Augenheilkunde und Optometrie, Allgemeines Krankenhaus, Wien, Österreich.

Methoden

Retrospektive Erhebung an 97 Augen bei 80 Patienten nach Operation einer altersbedingten Katarakt. Die postoperativen Untersuchungen fanden nach durchschnittlich 1,8 Jahren statt (Range: 1–4 Jahre) und umfassten die Feststellung der Best Corrected Visual Acuity (BCVA), Spaltlam-penuntersuchung, die subjektive Beurteilung der Linsen-Kapsel-Abstände (LK), Buttonholding, Falten der posterioren Kapsel, Anterior Capsular Opacification (ACO), regeneratorischer (PCOr) sowie fibrotischer PCO (PCOf). Die PCOr wurde zusätzlich objektiviert anhand retroilluminierter digitaler Bilder unter Verwendung des AQUA-Systems ausgewertet.

Ergebnisse

Die postoperative Best Corrected Visual Acuity (BCVA) betrug 0,8 Snellen ± 1,8 Linien (0,11 ± 0,19 [log MAR], n = 91). Das mittlere sphärische Äquivalent betrug -0,48 ± 0,65 dpt (Range: −1,75 bis +1,00). Der vordere Linsen-Kapsel-Abstand (LKa) war in 52 Augen (61%) positiv (n = 85), der hintere Linsen-Kapsel-Abstand (LKp) in 6 Augen (7%) positiv (n = 86). Eine ACO fand sich insgesamt bei 59 Augen (70%, n = 84). PCOf bestand bei 17 Augen (19%, n = 95), PCOr bei 69 Augen (78%, n = 88). Der subjektive PCOr-Score lag bei 1,9 ± 1,6 [Skala 0–10]. Die objektive Auswertung mittels AQUA ergab einen Score von 1,7 ± 1,4 [Skala 0–10]. Eine YAG-Kapsulotomie wurde bei 10 Augen (11%, n = 95) durchgeführt.

Zusammenfassung

Die wesentlichen Eigenschaften der ACR6D SE sind die weit posteriore Lage im Kapselsack (bedingt durch die 10°-Angulierung) mit einem hohen Anteil von Augen mit positivem LKa und dadurch weniger ACO. Die Angulierung der Haptiken und die scharfe umlaufende Kante dürften bei dieser Linse eine höhere PCOr, die aufgrund der geringen Fusion der Kapselblätter zu erwarten wäre, verhindern.

Summary

Background

To evaluate the clinical performance of the ACR6D SE (Corneal®), a hydrophilic acrylic intraocular lens (IOL) with a sharp optic edge and a 10° haptic angulation.

Setting

Department of Ophthalmology and Optometry, General Hospital, Vienna, Austria.

Methods

97 eyes of 80 patients with age-related cataract were included in this retrospective study and received an ACR6D SE IOL. The postoperative examinations took place after a mean of 1.8 years (range: 1–4 years) and comprised the assessment of the Best Corrected Visual Acuity (BCVA), slit-lamp examination, the subjective assessment of the lens-capsule distances (anterior: LKa, posterior: LKp), buttonholding, capsular folds, anterior capsular opacification (ACO) and regeneratory (PCOr) as well as fibrotic posterior capsule opacification (PCOf). In addition, the PCOr was evaluated in an objective manner using retroilluminated digital images and the AQUA system.

Results

The postoperative Best Corrected Visual Acuity (BCVA) was 0.8 Snellen ± 1.8 lines (0.11 ± 0.19 [log MAR], n = 91). The mean spherical equivalent was −0.48 ± 0.65 dpt (range: −1.75 to +1.00). The anterior lens-capsule distance (LKa) was positive in 52 eyes (61%) (n = 85), the posterior lens-capsule distance (LKp) positive in 6 eyes (7%, n = 86). ACO was found in 59 eyes (70%, n = 84). PCOf was found in 17 eyes (19%, n = 95), PCOr in 69 eyes (78%, n = 88). The subjective PCOr score was 1.9 ± 1.6 [scale 0–10]. The objective assessment showed a score of 1.7 ± 1.4 [scale 0–10]. Nd-YAG laser-capsulotomy was performed in 10 eyes (11%, n = 95).

Conclusion

The ACR6D SE shows a high rate of positive LKa which leads to less ACO. The angulation of the haptics and the sharp optic edge could inhibit higher PCOr that would be expected with a view to the lacking fusion of the capsular sheets.
