Abstract

Purpose: To evaluate the results and complications of deep anterior lamellar keratoplasty for treatment of keratoconusMethods: Forty eyes of 40 patients with keratoconus were included in this study. In all patients, big-bubble technique was tried to perform deep anterior lamellar keratoplasty. When failed, manual dissection was applied. Pre- and postoperative best-corrected visual acuity, refractive results, surgical technique and complications were analyzed. Results: There were 40 patients; 18 females and 22 males, with a mean age of 24.02±6.20 years (range15-36 years), the mean follow-up period was 14.92±2.39 months (range 10-18 months). Postoperative refraction was mean -3.29±1.46D (+2.00 to -5.50D) spherically, and mean -4.24±0.72D (-2.50 to -5.50D) cylendirically (p˂0.05). Keratometric values were 45.16±2.84D (37.30-50.89D) SimK1, and 48.50±2.78D (40.42-53.85D) SimK2. Postoperative pachymetry was mean 558.64±22.02µm (514-614µm), and endothelial cell density was mean 2369.52±265.59 cell/mm². Intraoperative microperforation of Descemet membrane occured in 6 patients. In postoperative follow-up, double anterior chamber developed in 3 eyes, epithelial defects were seen in 26 eyes, foreign bodies were detected in the graft-bed interface in 10 eyes, and suture abscess in 2 eyes. There were no endothelial rejection.Conclusion: Deep anterior lamellar keratoplasty is safe and effective surgical technique in patients with keratoconus. Visual outcome is comparable to standard penetrating keratoplasty, without the risk of endothelial rejection.

Özet

Amaç: Keratokonus tedavisinde derin ön lameller keratoplasti sonuçlarını ve komplikasyonlarını değerlendirmek Yöntem: Keratokonus tanısı almış 40 hastanın 40 gözü çalışmaya alındı. Tüm hastalarda büyük hava kabarcığı oluşturulmaya çalışılarak derin ön lameller keratoplasti uygulandı. Büyük hava kabarcığı oluşturulamayan olgularda manuel disseksiyon yapıldı. Ameliyat öncesi ve sonrası en iyi görme keskinliği, refraksiyon sonuçları, cerrahi teknik ve komplikasyonlar değerlendirildi.Bulgular: On sekizi kadın, 22’si erkek olan 40 hastanın ortalama yaşı 24,02±6,20 yıl (15-36 yıl), ortalama takip süresi 14,92±2,39 ay (10-18 ay) idi. Ameliyat sonrası refraksiyon değerleri sferik ortalama -3,29±1,46 D (+2,00 ile -5,50 D arası), silindirik ortalama -4,24±0,72 D (-2,50 ile -5,50 D arası) olarak bulundu (p˂0,05). Ameliyat sonrası keratometri değerleri SimK1 45,16±2,84D (37,30-50,89D), SimK2 48,50±2,78D (40,42-53,85) idi. Ameliyat sonrası pakimetri değerleri 558,64±22,02µm (514-614µm), endotel sayısı 2369,52±265,59 hücre/mm² bulundu. Hastaların 6’sında ameliyat sırasında mikroperforasyon gelişti. Ameliyat sonrası takiplerde 3 hastada ikinci ön kamara, 26 hastada epitel defekti, 10 hastada arayüzeyde yabancı cisim ve 2 hastada sütür absesi gözlendi. Hastaların hiçbirinde endotelyal red görülmedi. Sonuç: Derin ön lameller keratoplasti, keratokonus hastalarında görsel sonuçları standart penetran keratoplasti ile karşılaştırılabilir düzeyde olan, ve endotelyal red riski olmayan oldukça güvenli ve etkili bir cerrahi yöntemdir.
