Abstract

Aim: To evaluate corneal astigmatism change and intraocular lens (IOL) power values following ectropion surgery.
Materials and Methods: This comparative prospective research included patients with involutional ectropion who were divided using the snap-back test. The severity of ectropion increased progressively to reach the highest levels in Group 4. Patients underwent lateral tarsal strip procedures, and preoperative and 3-month postoperative biometry measurements were performed.
Results: While the mean flattest keratometry (K1), steepest keratometry (K2), and mean keratometry (Km) values exhibited nonsignificant increases at 3 months after surgery in Groups 1 and 2 (p>0.05 for all), the mean values of K1, K2, and Km were increased with statistical significance in Groups 3 and 4 at 3 months postoperatively (p<0.05 for all).
Conclusion: According to the snap-back test, ectropion in advanced stages will affect topographic values and IOL power calculations. If surgeons are going to perform cataract or refractive surgery after ectropion repair, they may consider changing the lens power selection accordingly.

Ektropion cerrahisinin astigmatik vektör ve oküler biyometrideki etkisi

Abstract

Amaç: Ektropiyon cerrahisi sonrası korneal astigmatizma değişimi ve göz içi lens (GİL) güç değerlerini değerlendirmek.
Gereç ve Yöntem: Bu karşılaştırmalı prospektif çalışmada involüsyonel ektropiyon hastaları snap-back testi kullanılarak şiddetlerine göre derecelendirildi. Ektropion şiddeti Grup 1’de en hafif Grup 4’te en ağır seviyedeydi. Hastalara lateral tarsal şerit işlemleri uygulandı ve ameliyat öncesi ve ameliyat sonrası 3. ayda biyometri ölçümleri yapıldı.
Bulgular: Ortalama en düz keratometri (K1), en dik keratometri (K2) ve ortalama keratometri (Km)) değerleri Grup 1 ve 2'de ameliyattan sonraki 3 ayda anlamlı olmayan artışlar gösterirken (hepsi için p>0,05), K1, K2 ve Km ortalama değerleri ameliyat sonrası 3. ayda Grup 3 ve 4'te istatistiksel anlamlı artış gösterdi (hepsi için p<0,05).
Sonuç: Snap-back testine göre ileri evredeki ektropiyonda topografik değerleri ve GİL gücü hesaplamalarını etkileyecektir. Cerrahlar ektropiyon onarımı sonrası katarakt veya refraktif cerrahi ameliyatı yapacaklarsa lens gücü seçimini buna göre değiştirmeyi düşünebilirler.
