Arka kapsül bütünlüğü olmayan olgularda arka kamara göz içi mercek implantasyonu

Amaç: Bu çalışmanın amacı yeterli arka kapsüler desteği olmayan hastalarda primer iris-fiksasyonlu ve skleral fiksasyonlu arka kamara göz içi mercek implantasyonlarının sonuçlarını karşılaştırmaktır.Gereç ve Yöntem: Katarakt ameliyatı sırasında yetersiz arka kapsül desteği nedeniyle primer sütüre arka kamara göz içi mercek implantasyonu yapılan hastaların prospektif analizi yapıldı. En iyi düzeltilmiş görme keskinliği, görme keskinliği artışı ve gelişen komplikasyonlar değerlendirildi.Bulgular: Çalışmamızda 13 hastaya (%30,2) iris-fiksasyonlu ve 30 hastaya (% 69,8) skleral fiksasyonlu arka kamara göz içi mercek implantasyonu uygulandı. İris fiksasyonlu grupta 11 hastada (%84,6), skleral fiksasyonlu grupta 25 hastada (%83,3) görme keskinliği , Snellen eşeline göre en az 1 sıra arttı. İris fiksasyonlu grupta % 30,8 hastada (n = 4), skleral fiksasyonlu grupta % 50 hastada (n = 15) 0,5 ve üzerinde en iyi düzeltilmiş görme keskinliği mevcuttu. Sonuç: Primer iris-fiksasyonlu ve skleral fiksasyonlu arka kamara göz içi mercek implantasyonları tatmin edici görsel sonuçlar vermektedir. Sütüre arka kamara göz içi merceğin fikse edileceği bölgenin seçiminde altı çizilmesi gereken noktalar; gözünün ameliyat öncesi durumu, arka kamara göz içi merceğin fikse edilecek bölgenin durumu, lensin türü ve cerrahın tercihidir.

Implantation of posterior chamber intraocular lens in cases without posterior capsular union

Purpose: The purpose of this study was to compare the results of primary iris-fixated and scleral-fixated posterior chamber intraocular lens implantations in patients with in sufficient capsular support.Materials and Methods: A prospective analysis of patients who underwent primary sutured posterior chamber intraocular lens implantation secondary to insufficient posterior capsular support during cataract surgery was performed. Outcome measures were; best corrected visual acuity, change in visual acuity and complications.Results: In this study, 13 patients (30.2%) underwent iris-fixated and 30 patients (69.8%) scleral-fixated posterior chamber intraocular lens implantations. The visual acuity improved by at least one Snellen line or remained unchanged in 11 patients (84.6%) in the iris-fixated group and in 25 patients (83.3%) in the scleral-fixated group. Patients with best corrected visual acuity of 0.5 or higher were 30.8% (n = 4) in the iris-fixated group and 50% (n = 15) in scleral-fixated group postoperatively. Conclusion: Both primary iris- fixated and scleral-fixated posterior chamber intraocular lens implantations can provide favorable visual outcomes. The points to underline for the fixation of the sutured posterior chamber intraocular lens are; the preoperative condition of the patient's eye, the situation of the area to be fixed, the type of lens and the preference of the surgeon.
