Abstract

Purpose: The aim of this study was to investigate the effect of ultrasound time on macular thickness and the influence of macular thickness on visual acuity after uneventful phacoemulsification surgery. Material and Method: In this study, 42 eyes of 30 cataract patients who underwent uncomplicated phacoemulsification surgery were evaluated. The phacoemulsification was performed using 20% “pulse mode” ultrasound energy. The ultrasound time of each case was noted. Visual acuity (logMAR) and macular thickness were measured pre- and postoperatively. Macular thickness was measured by “spectraldomain” optical coherence tomography using “macular map 6” (MM6) programme. Re sults: All patients who underwent uncomplicated phacoemulsification surgery showed a statistically significant improvement in bestcorrected visual acuity in postoperative first and third months (p=0.001). When minimum central macular, mean central zone, mean parafoveal and mean perifoveal macular thicknesses in the postoperative first week, first month and third month were compared with the preoperative values, a statistically significant increase in all zones was detected (p=0.001). The mean ultrasound time applied was 128 sec. ±11 SD: 70.17. No statistically significant correlation was found between ultrasound time and increase in macular thickness in the postoperative first week, first month and third month. There was no significant correlation between best-corrected visual acuity and minimum central macular/central zone macular thickness. Discussion: This study shows that in patients who underwent uneventful phacoemulsification surgery, there is an increase in macular thickness independent of ultrasound time. We also found no correlation between macular thickness and visual acuity.

Özet

Amaç: Fakoemülsifikasyon cerrahisi sırasında uygulanan ultrason süresinin olguların maküla kalınlığına ve maküla kalınlıklarının görme keskinlikleri üzerine etkisinin araştırılması. Gereç ve Yöntem: Bu çalışmada fakoemülsifikasyon cerrahisi komplikasyonsuz tamamlanan 30 hastanın 42 gözü incelendi. Ameliyatlar %20 “pulse mode” ultrason gücü ile fakoemülsifikasyon cihazı kullanılarak yapıldı. Toplam ultrason süresi kaydedildi. Hastaların, cerrahi öncesi ve cerrahi sonrası 1.hafta, 1.ay ve 3.ayda, görme keskinlikleri (logMAR) alındı, oftalmolojik muayeneleri yapıldı ve maküla kalınlıkları “spektral domaine” optik koherens tomografi cihazı ile “macular map 6” (MM6) programı kullanılarak ölçüldü. Sonuçlar: Olguların cerrahi sonrası 1.ay ve 3.ay takiplerinde gözlerin tamamında istatiksel olarak anlamlı bir görme artışı saptandı (p=0,001). Cerrahi öncesi ile cerrahi sonrası 1.hafta, 1.ay ve 3.ayda minimum santral maküla kalınlığı, santral, parafoveal ve perifoveal alanlardaki ölçümler arasında anlamlı kalınlık artışı saptandı (p=0,001). Cerrahi sırasında olgulara uygulanan ultrason süresi ortalaması 128sn±11, SD: 70,17 idi. Ultrason süresi ile santral, parafoveal ve perifoveal alanlar içerisindeki 1.hafta, 1.ay ve 3.ay maküler kalınlık artışları arasında anlamlı bir ilişki saptanmadı. Olguların cerrahi sonrası 3.aydaki görme artışları ile santral zondaki maküla kalınlığı ve minimum santral maküla kalınlığı arasında da anlamlı bir ilişki saptanmadı. Tar t›fl ma: Fakoemülsifikasyon cerrahisi sonrasında tüm olgularda ultrason süresinden bağımsız olarak maküla kalınlık artışı olmaktadır. Ayrıca maküla kalınlık artışı ile görme keskinlikleri arasında da istatiksel olarak anlamlı bir korelasyon bulunmamıştır.
