Abstract

Purpose: To analyze the stromal pocket and opaque bubble layer (OBL) formation during femtosecond laser flap creation using the anterior segment optical coherence tomography (AS-OCT). Materials and Methods: During femtosecond laser assisted laser in situ keratomileusis (LASIK), 20 eyes of 10 patients were examined prospectively by AS-OCT to evaluate the flap-OBL-pocket relations immediately after flap creation. High resolution corneal images in four quadrants were recorded and analyzed using the software's flap tool. Results: The mean age of the patients (3 women, 7 men) was 42.06.2 years. No preoperative or postoperative complications were observed. An OBL was observed in 10 eyes without pocket formation; the mean OBL thickness was 251 μm, and the mean OBL depth was 393.8 μm. Pocket formation was programmed to be performed on 10 eyes; it was rudimentary and could hardly be detected in 3 eyes by AS-OCT. In eyes containing stromal pocket, a lower amount of OBL was also found to expand to the limbus. The mean pocket thickness was 85 μm and the mean pocket depth was 301.2 μm. Conclusion: AS-OCT is a useful tool to evaluate the flap-OBL-pocket relations in vivo immediately after femtosecond laser during LASIK procedures. The presence of flap related stromal pockets significantly decrease OBL formation in femtosecond laser assisted LASIK.

Özet

Amaç: Femtosaniye lazerle flep oluşturulurken meydana gelen stroma cebi ve opak kabarcık tabakası gelişiminin (OPKT) ön segment optik koherens tomografisi (ÖS-OKT) ile analiz edilmesi. Gereç ve Yöntemler: Femtosaniye lazer yardımıyla yapılan lazer in situ keratomileusis (LASİK) ameliyatı esnasında flep-OPKT-cep ilişkisini incelemek amacıyla 10 hastanın 20 gözü flep oluşturulmasından hemen sonra ÖS-OKT ile geriye dönük olarak incelendi. Yüksek çözünürlüklü kornea görüntüleri 4 kadranda kaydedildi ve yazılımdaki flep aracı ile analiz edildi. Bulgular: Hastaların (3 kadın, 7 erkek) yaş ortalaması 42.0±6.2 yıldı. Ameliyat öncesi ve sonrası komplikasyon gelişmedi. OPKT cep formasyonu olmayan hastalarda gözlendi; ortalama OPKT kalınlığı 251μm ve ortalama OPKT derinliği 393.8 μm idi. On hastada cep oluşumu önceden programlanmıştı; bu gözlerden üçünde cebin güçlükle saptanabilecek kadar küçük oluştuğu gözlendi. Stroma cebi olan hastalarda az miktarda OPKT'nin limbusa kadar yayıldığı gözlemlendi. Ortalama cep kalınlığı 85 μm ortalama cep derinliği 301.2 μm idi. Sonuç: ÖS-OKT, LASİK prosedürlerinden hemen sonra flep-OPKT-cep ilişkilerini in vivo değerlendirmek bakımından faydalı bir gereçtir. Femtosaniye lazer yardımıyla yapılan LASİK ameliyatında fleple bağlantılı stroma cebinin varlığı OPKT oluşumunu anlamlı olarak azaltmaktadır.
