ABSTRACT
 Objective: To evaluate the outcomes of posterior-chamber phakic intraocular lens (pIOL) implantation in patients with high myopia. Material and Methods: Seventy-six eyes of 38 patients who had high myopia and undergone Eyecrylphakic IOL implantation were enrolled in the study. Eighteen of them (47%) were males and 20 (53%) were females. Their mean age was 28.97±4.10 (22-36) years. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), autorefractive and keratometric measurements were evaluated pre and postoperatively. Results: The mean 1st week, 1st month and 6th month postoperative spherical, astigmatic and spherical equivalent (SE) values were significantly lower than those of preoperative values, and the mean 1st week, 1st month and 6th month postoperative UCVA and BCVA values were significantly higher than preoperative values (p0.05). The postoperative first-week mean spherical value was 0.11±0.44 D, and it was stable until the 6th month. Postoperative 6th month mean endothelial cell loss was 3% in comparison with preoperative values. The difference was not significant (p>0.05). Additionally, no abnormal morphologic changes in endothelial cell layer were observed in specular microscopy. Conclusion: Eyecrylphakic IOL implantation is a safe, effective, predictable, and stable treatment method for high-myopia patients in the short-term. Long-term results of pIOL implantation should be investigated in further studies.

Keywords: High myopia; phakic IOL; spherical equivalent; uncorrected visual acuity
ÖZET
 Amaç: Yüksek miyopisi olan hastalarda arka kamara fakik intraoküler lens (pIOL) implantasyonunun görsel sonuçlarını değerlendirmek. Gereç ve Yöntemler: Yüksek miyopisi olan ve Eye cryl Fakik IOL implantasyonu uygulanan 38 hastanın 76 gözü çalışma kapsamına alındı. Hastaların 18'i (%47) erkek, 20'si ise (%53) kadındı. Ortalama yaşları 28,97±4,10 (22-36) yıl idi. Düzeltilmemiş görme keskinliği, düzeltilmiş görme keskinliği, otorefraktif ve keratometrik ölçümler ameliyat öncesi ve sonrasında değerlendirildi. Bulgular: Ortalama ameliyat sonrası 1. hafta, 1. ay ve 6. ay sferik, astigmatik ve sferik eşdeğer (SE) ameliyat öncesi değere göre anlamlı olarak daha düşüktü ve ameliyat sonrası düzeltilmemiş ve düzeltilmiş görme keskinliği, ameliyat öncesine göre anlamlı olarak daha yüksekti (p0,05). Ameliyat sonrası 1. hafta ortalama sferik değer 0,11 ± 0,44 D idi ve bu değer 6. aya kadar stabil seyretti. Postoperatif 6. aydaki endotel hücre kaybı %3'tü, preoperatif değere gore anlamlı bir düşüş değildi (p>0,05). Ayrıca, speküler mikroskopide endotel hücre tabakasında anormal morfolojik değişiklikler gözlenmedi. Sonuç: Eyecryl Fakik IOL implantasyonu, yüksek miyopisi olan hastalarda kısa dönemde güvenli, etkin ve ön görülebilir bir tedavi sağlamaktadır. Uzun dönem sonuçları için ileri çalışmaların yapılması gerekir.

Anahtar Kelimeler: Yüksek miyopi; fakik IOL; sferik eşdeğer; düzeltilmemiş görme keskinliği
