Zusammenfassung

Hintergrund: Wir berichten über Resultate, Wirkungen und Sicherheit der Hinterkammerlinse beim phaken Patienten mit mittlerer bzw. hochgradiger Kurzsichtigkeit. Material und Methoden: 23 Augen von 12 Patienten mit einem präoperativen mittleren refraktiven sphärischen Äquivalent von - 10,94 ± 5,97 D wurde eine Staar-ICL™-Hinterkammerlinse implantiert. Mittleres Follow-up war 12,9 ± 7,4 Monate (4 - 24 Monate). Die prä-und postoperative unkorrigierte und bestkorrigierte Sehschärfe, die subjektive Refraktion, der intraokulare Druck, die Keratometrie, die Zentrierung der Linse und die vorderen subkapsulären Verdichtungen wurden erfasst. Ergebnisse: Die postoperative unkorrigierte Sehschärfe verbesserte sich bei allen Augen. Die beste Korrektur erhöhte sich von 0,82 ± 0,39 auf 1,05 ± 0,24. Die Verbesserung war statistisch relevant (Student-t-Test, p = 0,0097). Das postoperative mittlere refraktive sphärische Äquivalent war - 0,82 ± 1,42 D (p < 0,0001), der intraokulare Druck war 15,65 ± 2,72 mm Hg. Die Linsen blieben befriedigend zentriert und keine vorderen subkapsularen Verdichtungen wurden beobachtet. Drei Patienten litten an postoperativen Komplikationen ohne Verminderung der Sehschärfe. Schlussfolgerung: Die Verwendung einer intraokularen Hinterkammerlinse beim phaken Patienten mit mittlerer bis hochgradiger Kurzsichtigkeit ist eine sichere Technik. Langzeitergebnisse stehen noch aus.

Implantation of a foldable Collamer lens as a posterior chamber phakic intraocular lens in myopia

Background: The purpose of this study was to report results, effectiveness and safety of implanting a negative collagen/HEMA copolymer posterior chamber phakic intraocular lens in moderate to highly myopic eyes. Material and methods: 23 eyes from 12 patients with a mean preoperative spherical equivalent refraction of - 10.94 ± 5.97 D underwent a refractive procedure with the Staar ICL™ posterior chamber phakic intraocular lens. The average follow-up was 12.9 ± 7.4 months (range 4 - 24 months). Preoperative and postoperative uncorrected and bestcorrected visual acuity, subjective refraction, intraocular pressure, keratometry, ICL™ centration and anterior subcapsular opacities were evaluated. Results: Postoperative uncorrected visual acuity improved in all eyes. The best corrected visual acuity increased from 0.82 ± 0.39 preoperatively to 1.05 ± 0.24 postoperatively. The gain in visual acuity was statistically significant (Student t-test, p = 0.0097). The mean postoperative spherical equivalent refraction was - 0.82 ± 1.42 D (p < 0,0001). The mean postoperative intraocular pressure was 15.65 ± 2.72 mm Hg. The intraocular contact lens remained well centred in all eyes and no anterior subcapsular opacities were observed. Three patients underwent transcient complication without affecting the visual outcome. Conclusion: The use of a posterior chamber phakic intraocular lens in myopic eyes is a safe procedure to correct moderate to high myopia. Long-term results are still unknown.
