Abstract

Purpose: To evaluate the results of Pars Plana Vitrectomy (PPV) with either phacofragmentation or crushing technique for the removal of retained lens materials in the vitreous during the cataract surgery. Materials and Methods: Twenty seven patients (17 male, 10 female) who underwent PPV for the removal of the lens fragments in the vitreous as a complication of cataract surgery from May 1998 to January 2005 were retrospectively evaluated; in terms surgical techniques, peroperative and postoperative complications and visual success. Results: The mean age of the 27 patients was 70.7 years(56-86 years) and the average follow-up period was 10.7 (3-36) months. The average period between cataract surgery and PPV was 14.8 days (2-48). Intraocular inflammation (51.8%), corneal edema (44.4%), and increased intraocular pressure (IOP) (29.6%) were the most common findings before PPV. The lens material was removed with phacofragmentation in 12 patients, crushed between the vitrectomy instrument and light pipe in 10 patients and through limbal extraction with the help of perfluorocarbon liquid in 5 patients. The peroperative complications were three iatrogenic tears in phacofragmentation groups (25%) and one choroidal detachment in crushing group (10%). The final visual acuity was (p+p+)-hand motion in 3 eyes, counting finger at 1-4 meters in 4 eyes, 0.1-0.4 in 10 eyes and 0.5 or better in 10 eyes. The visual acuity improved in 74.1% of eyes, remained the same in 18.5% of eyes, and deteriorated in 7.4% of eyes in the postoperative period. Postoperative complications were temporary corneal edema (18.5%), increased intraocular pressure (11.1%), rhegmatogenous retinal detachment (7.4%), cellophane maculopathy (7.4%) and bullose keratopathies (7.4%). Conclusion: Pars plana vitrectomy with crushing technique may be safer than phacofragmentation in selective cases with retained lens material after cataract surgery.

Özet

Amaç: Katarakt cerrahisi sırasında vitreus içine lükse lens parçalarına fakofragmantasyon veya crushing tekniği kullanılarak yapılan pars plana vitrektomi (PPV) sonuçlarının değerlendirilmesi. Gereç ve Yöntem: Mayıs 1998-Ocak 2005 tarihleri arasında katarakt cerrahisi sırasında vitreusa düşmüş nükleus parçalarının çıkarılması amacıyla PPV yapılan 17 erkek 10 kadın toplam 27 olgu, uygulanan cerrahi teknik, peroperatif ve postoperative komplikasyonlar ve görsel başarı yönünden retrospektif olarak incelendi. Bulgular: 27 olgunun ortalama yaşı 70.7 (56-86) ve ortalama takip süresi 10.7 (3-36) ay idi. Katarakt cerrahisi ile PPV arasında geçen süre ortalama 14.8 (2-48) gündü. PPV öncesi en sık rastlanan bulgular göz içi enflamasyon (%51.8), kornea ödemi (%44.4) ve göz içi basınç (GİB) artışı (%29.6) idi. Olguların 12 ‘sinde fakofragmantasyon, 10’unda vitrektomi ve ışık probu kullanılarak yapılan crushing yöntemi uygulanırken 5 olguda lens sıvı perflorokarbon ile yüzdürülerek limbal yolla çıkarıldı. Peroperatif komplikasyon olarak fakofragmantasyon uygulanan 3 (%25) gözde iatrojenik yırtık, crushing uygulanan 1 (%10) gözde koroid dekolmanı gelişti. Sonuç görme keskinliği 3 olguda p+p+ - el hareketi, 4 olguda 1-4 mps, 10 olguda 0.1-0.4 ve 10 olguda da 0.5 ve üzeri idi. Postoperatif dönemde görme keskinliğinin %74.1 olguda arttığı, %18.5 olguda aynı düzeyde kaldığı ve %7.4 olguda ise azaldığı saptandı. Postoperatif dönemde geçici kornea ödemi %18.5, medikal tedavi ile kontrol edilebilen GİB yüksekliği %11.1, regmatojen retina dekolmanı %7.4, selofan makülopati 7.4 ve büllöz keratopati %7.4 oranında saptandı. Sonuç: Katarakt cerrahisi sonrası vitre içine lükse olmuş lens parçalarının temizlenmesinde PPV ile beraber uygun olgularda crushing yöntemi fakofragmantasyona göre daha güvenli bir cerrahi yöntem olabilir.
