Abstract

Objective: To examine the clinical outcomes of mini-scleral lenses for visual rehabilitation after penetrating keratoplasty. Material and Method: A retrospective review was conducted for 14 patients (14 eyes) who had a history of prior penetrating keratoplasty and were fit with mini-scleral lenses between January 2013 and May 2014. Mini-scleral contact lens were applied to the patients. Topographic measurements were evaluated with Sirius Scheimpflug kamera. The main outcome measurements were best corrected visual acuity according to logMAR, keratometric values (K1, K2, Kmax), topographic astigmatism and scleral lens parameters. Results: The indication for penetrating keratoplasty was keratoconus in 5 eyes, pseudophakic bullous keratopathy in 6 eyes central opacity in 1 eye, Fuchs’ endothelial dystrophy in 1 eye. The best-corrected visual acuity with a scleral lens was increased to 0.10±0.14 logMAR from 0.8±0.27 logMAR (p<0.001). Similarly K1, K2, Kmax and topographic astigmatism values were improved significantly with scleral lens (p<0.001). Scleral lens parameters were BC 7.80±6.57 mm, Vault=400 μm and scleral curve=13.50 mm. Conclusion: Mini-scleral use allowed successful visual rehabilitation after penetrating keratoplasty. Majority of patients achieved 20/40 vision or better. Our results reveal that mini-scleral lenses can be an succesful visual rehabilitation method for the treatment of irregular corneal astisgmatism.

Özet

Amaç: Mini-skleral lenslerin penetran keratoplasti sonrasındaki görsel rehabilitasyon sonuçlarını değerlendirmek. Gereç ve Yöntem: Retrospektif çalışmaya Ocak 2013-Mayıs 2014 arasında penetran keratoplasti yapılan 14 hastanın 14 gözü dahil edildi. Tüm hastalara mini-skleral kontakt lens uygulandı. Topografik ölçümleri Sirius Scheimpflug kamera ile yapıldı. LogMAR eşeline göre en iyi düzeltilmiş görme keskinliği, keratometrik değerler (K1, K2, Kmax), topografik astigmatizma ve skleral lens parametreleri değerlendirildi. Bulgular: Keratoplasti endikasyonları 5 hastada keratokonus, 6 hastada psödofakik büllöz keratopati, 2 hastada geçirilmiş travmaya bağlı santral korneal opasite, 1 hastada ise Fuchs’ endotelyal korneal distrofi idi. Mini-skleral lens öncesinde gözlükle en iyi düzeltilmiş görme keskinliği düzeyi 0,8 logMAR’dan 0,10±0,14 logMAR’a yükselmiştir (p<0,001). Benzer şekilde K1, K2, Kmax ve topografik astigmatizma değerlerde skleral lens uygulama sonrasında istatistiksel olarak anlamlı bir artış izlendi (p<0,001). Skleral lens parametreleri ortalamaları ise BC= 7,80 ± 6,57 mm, Vault=400 μm ve skleral eğim ise 13,50 mm olarak bulundu. Sonuç: Mini-skleral lens kullanımı penetran keratoplasti sonrası görsel rehabilitasyonu başarılı bir şekilde artırmaktadır. Hastaların büyük bir bölümünde 20/40 ve üzerinde görme artışı sağlanmıştır. Çalışmamızın sonuçlarına göre mini-skleral lensler korneal düzensizliğe bağlı düzensiz astigmatizma tedavisinde başarılı bir görsel rehabilitasyon seçeneğidir.
