Abstract

Abstract Purpose: To evaluate the changes in corneal clarity and anterior segment parameters following phacoemulsification surgery. Material and Methods: Fifty eyes of 36 patients with a complaint of blurred vision diagnosed with cataract who underwent phacoemulsification surgery were included in the study. Anterior chamber angle (ACA), anterior chamber volume (ACV), angle opening distance (AOD), trabecular iris space area (TISA), and anterior chamber parameters measured with anterior segment optical coherence tomography (AS-OCT) and corneal tomography were evaluated. Densitometry values prior to the surgery, at the first week, and first month postoperatively were compared. Results: Of all patients 19 (52.8%) were female. The mean age was 62.8±11.3 years. The mean best corrected visual acuity (BCVA) of the patients increased significantly, and the intraocular pressure (IOP) decreased significantly after surgery (p=0.001). The ACA, AOD, and TISA via AS-OCT increased significantly postoperatively (p=0.001 for all). A significant postoperative increase was observed in the ACA and ACV obtained with the Pentacam HR device (p=0.001 for all). In corneal densitometry values, a significant increase was observed in several circular area measurements in the anterior, central, and total layers (p<0.05 for all), while no significant difference was observed in the posterior layer (p>0.05). Conclusion: The anterior chamber deepens following cataract surgery, and an increase in ACA, AOD and TISA is observed. Increase in corneal densitometry particularly within the anterior and central layers has been postulated, potentially attributable to postoperative corneal edema, surgery-induced onset of dry eye, and epithelial alterations secondary to topical medication use.

Özet

Özet Amaç: Fakoemülsifikasyon cerrahisi sonrası kornea şeffaflığı ve ön segment parametrelerindeki değişimleri değerlendirmek. Gereç ve Yöntem: Çalışmaya, görme bulanıklığı şikayeti bulunan, katarakt tanısı konmuş ve fakoemülsifikasyon cerrahisi yapılmış 36 hastanın 50 gözü dahil edildi. Ön segment optik koherens tomografi (ÖS-OKT) ve kornea tomografisi ile ölçülen ön kamara açısı (ÖKA), ön kamara hacmi (ÖKH), açı açılma mesafesi (AAM), trabeküler iris boşluk alanı (TİBA) ve ön kamara parametreleri değerlendirildi. Ameliyat öncesi, ameliyat sonrası birinci hafta ve birinci aydaki kornea dansitometri değerleri karşılaştırıldı. Bulgular: Hastaların 19'u (%52,8) kadındı. Ortalama yaş 62,8±11,3 yıldı. Hastaların ortalama en iyi düzeltilmiş görme keskinliği (EİDGK) cerrahi sonrası anlamlı şekilde artarken, göz içi basıncı (GİB) anlamlı şekilde azaldı (p=0,001 tümü için). ÖS-OKT ile ölçülen ÖKA, AAM ve TİBA değerlerinde ameliyat sonrası dönemde anlamlı artış izlendi (p=0,001 tümü için). Pentacam HR cihazı ile elde edilen ÖKA ve ÖKH değerlerinde ameliyat sonrası anlamlı bir artış gözlendi (p=0,001 tümü için). Korneal dansitometri değerlerinde; ön, merkezi ve total tabakalardaki çeşitli dairesel alan ölçümlerinde anlamlı artış saptanırken (p<0,05 tümü için), arka tabakada anlamlı bir fark gözlenmedi (p>0,05). Sonuç: Katarakt cerrahisini takiben ön kamara derinleşmekte; ÖKA, AAM ve TİBA değerlerinde artış görülmektedir. Özellikle ön ve merkezi tabakalarda kornea dansitometrisinde gözlenen artışın; ameliyat sonrası kornea ödemi, cerrahi kaynaklı kuru göz başlangıcı ve topikal ilaç kullanımına ikincil gelişen epitelyal değişikliklere bağlı olabileceği öne sürülmüştür.
