Abstract

Purpose: evaluate the reasons for intraocular lens (IOL) reposition and exchange in our clinic. Materials and Methods: 75 eyes of 73 patients with a history of cataract extraction having either IOL reposition or IOL exchange in our clinic was evaluated retrospectively from the patient charts. Visual acuity, the place of IOL implantation (either anterior or posterior chamber), the structure of GIL and indication of IOL exchange or reposition was noted. Results: In the study 39 eyes underwent IOL exchange and 36 eyes IOL reposition. Of 39 eyes having IOL exchange 12 eyes had bullous keratopathy, 10 eyes incorrect IOL power, 7 eyes (one eye due to capsular phymosis and 6 eyes due to psoudoexfoliation) IOL subluxation, 5 eyes cataract progression secondary to fakic IOL, 4 eyes IOL opacification and one eye with fakic IOL experienced chronic inflammation. Of 36 eyes having IOL reposition 13 had zonular damage (12 eyes due to pseudoexfoliation and one eye due to ocular travma), 4 eyes capsular phymosis and 19 eyes IOL dislocation due to either one or both of the haptics remaining outside the capsular bag. Conclusion: A significant number of eyes requiring IOL exchange or reposition may be prevented by the experience and cautiousness (vigilance) of the surgeon.

Özet

Amaç: Kliniğimizde uygulanan göz içi lens (GİL) repozisyonu ve değişimi nedenlerini tespit etmek. Gereç ve Yöntem: Katarakt cerrahisi geçirmiş olup kliniğimizde GİL çıkarılmış veya repozisyon uygulanmış olan 73 hastanın 75 gözü incelendi. Hastaların yaşları, cinsleri, ilk muayenedeki GİL yeri(ön kamara/arka kamara) ve GİL yapısı, görme keskinlikleri (GK) ve GİL çıkarılma veya repoze etme endikasyonları kaydedildi. Bulgular: Yetmiş beş gözün 39’una (%52 ) GİL çıkartılması, 36’sına (%48) GİL repozisyonu uygulanmıştır. GİL’leri çıkartılan gözlerin; 12’sinde (%16) büllöz keratopati, 10’unda (%13) hatalı dioptride GİL, 7’sinde (%9) arka kamara GİL subluksasyonu 6’sı psödoeksfolyasyona bağlı, 1’i kapsüler fimozise bağlı), 5’i (%6) fakik GİL’e bağlı katarakt gelişimi, 4 gözde (%5) GİL kesafeti ve 1 gözde de (%1) fakik ön kamara GİL sonrası kronik inflamasyon mevcuttu. GİL repozisyonu uygulanan 36 gözün 13’nde (%36) (12 gözde psödoeksfolyasyona bağlı, 1 gözde travmaya bağlı) zonül hasarı mevcuttu. 4 gözde (%11) kapsül fimozisi nedeni ile; 19 gözde(%53) ise GİL’in bir veya iki haptiğinin kapsüler kese içi yerine kapsül üzerinde kalmasıyla dislokasyon gelişmişti. Sonuç: GİL çıkarılması ve repozisyonu gerektiren patolojilerin önemli bir kısmı cerrah tarafından tecrübe ve dikkat ile önlenebilecek nedenlerdir.
