Abstract

Objectives: To evaluate two-year results of small-incision lenticule extraction (SMILE) for correction of high myopia.Materials and Methods: Forty-five eyes of 35 patients with mean spherical equivalent (SE) of -7.10±0.95 D who underwent routine SMILE by a single surgeon and were followed for at least 2 years were analyzed by retrospective chart review. SMILE was performed with a Visumax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Follow-up intervals were at 1, 6, 12, and 24 months after surgery. Uncorrected and best corrected distance visual acuity (CDVA), corneal wavefront measurements, and all complications were recorded.Results: After 2 years, 86% of eyes with plano target had an uncorrected distant visual acuity (VA) of 20/20 or better. Two percent of eyes lost 1 line of CDVA, while 32% gained 1 line. The mean SE after 2 years was -0.30±0.50 D. Corneal total high-order aberrations (HOA) increased from 0.43 to 0.92 µm at postoperative 12 months. There were metallic foreign bodies at the corneal interface in 1 eye of 1 patient which caused no decrease in VA.Conclusion: SMILE for high myopia seems safe and effective in light of two-year follow-up results. The procedure caused a moderate increase in HOA.

Özet

Amaç: Yüksek miyopi tedavisinde küçük kesiden lentikül çıkarılması (SMILE) işleminin iki yıllık sonuçlarını değerlendirmektir.Gereç ve Yöntem: Ortalama sferik eşdeğer (SE) değeri -7,10±0,95 D olan ve tek bir cerrah tarafından rutin SMILE işlemi uygulanmış 35 hastanın 45 gözü çalışmaya dahil edildi ve 2 yıllık takibi içeren dosyalar retrospektif olarak tarandı. SMILE cerrahileri Visumax femtosaniye lazer cihazı (Carl Zeiss Meditec, Jena, Almanya) ile gerçekleştirildi. Cerrahi sonrası takipler 1., 6., 12. ve 24. aylarda yapıldı. Çalışma kapsamında düzeltmesiz görme keskinliği (GK) ve en iyi düzeltilmiş görme keskinlikleri (DGK), korneal wavefront ölçümlerinin verileri ve tüm komplikasyonlar kaydedildi. Bulgular: Cerrahi sonrası 24. ayda, emetropi hedeflenen hastaların %86'sı 20/20 ve üzeri GK'ya sahipti. Gözlerin %2'si DGK'da bir sıra kaybederken, %32'si bir sıra kazanmıştı. İki yıllık takip sonrası ortalama SE değeri -0,30±0,50 D olarak saptandı. Korneanın yüksek sıralı aberasyonlarının (YSA) toplamı 0,43 µm'den 12. ay sonunda 0,92 µm'ye yükselmişti. Bir hastanın bir gözünde korneal ara yüzeyde metalik yabancı cisimler saptandı ancak bunların GK'da azalmaya sebep olmadığı tespit edildi.Sonuç: Yüksek miyopinin tedavisinde SMILE cerrahisinin 2 yıllık takibinin sonuçları güvenli ve etkili bir tedavi seçeneği olduğunu göstermektedir. Bu cerrahi YSA'larda orta düzeyde bir artışa sebep olmuştur.
