Abstract

Purpose: To examine foldable intraocular lens (IOL) movement along the anteroposterior axis, measured as a change in anterior chamber depth (ACD) caused by accommodation in young pseudophakic cases. Material and Method: This study included twenty-two eyes of 22 patients with uveitis (group 1) and twenty-five eyes of 25 patients with diabetes mellitus (group 2), who were planned for phacoemulsification and foldable IOL implantation. Before and two months after surgery, anterior chamber depth (ACD) was measured with Orbscan Corneal Topography System (Orbtek, Inc.) during physiological accommodation and two hour after instillation of cyclopentolate 1%. Results: The mean age of the patients was 26.4±9.8 years in group 1 (8 female, 14 male) and 29.3±5.7 years in group 2 (12 female, 13 male). The values of mean preoperative ACD were 3.52±0.42 mm in group 1 and 3.61±0.39 mm in group 2 during physiological accommodation; 3.63±0.37 mm in group 1 and 3.71±0.41 mm in group 2 after cyclopentolate instillation. The values of mean postoperative ACD were 4.38±0.23 mm in group 1 and 4.43±0.36 mm in group 2 during physiological accommodation, 4.56±0.28 mm in group 1 and 4.61±0.31 mm in group 2 after cyclopentolate instillation. The mean postoperative ACD was significantly higher than the mean preoperative ACD in the two groups. There was no significant difference in IOL movement between accommodation and cyclopentolate instillation in the two groups. Discussion: With accommodative effort, ciliary muscle contracts and capsular bag expands, which might allow the IOL to move forward. However, in this study, there was no significant difference in IOL movement along the anteroposterior axis, induced by accommodation in eyes of young pseudophakic patients.

Özet

Amaç: Genç psödofakik gözlerde, akomodasyonla oluşan ön kamara derinlik değişikliklerini ölçerek katlanabilir göz içi lenslerin (GİL) ön arka eksendeki hareketini incelemek. Gereç ve Yöntem: Bu çalışmaya fakoemülsifikasyon ve katlanabilir GİL konulması planlanan 22 üveitli olgunun 22 gözü ve diyabetes mellituslu 25 olgunun 25 gözü dahil edildi. Ameliyat öncesi ve ameliyattan 2 ay sonra olguların fizyolojik yakın nokta akomodasyonu sırasında ve %1’lik siklopentolat damlatıldıktan 2 saat sonra Orbtek Orbscan Korneal Topografi ile ön kamara derinliği (ÖKD) ölçümleri yapıldı. Sonuçlar: Olguların ortalama yaşı 1. grupta 26,4±9,8 yıl (8 kadın, 14 erkek), 2. grupta 29,3±5,7 yıldı (12 kadın 13 erkek). Ameliyat öncesi ÖKD, fizyolojik yakın nokta akomodasyonu sırasında 1. grupta 3,52±0,42 mm, 2. grupta 3,61±0,39 mm, siklopentolat damlatıldıktan sonra ise 1. grupta 3,63±0,37 mm, 2. grupta 3,71±0,41 mm olarak bulundu. Ameliyat sonrası ÖKD, fizyolojik yakın nokta akomodasyonu sırasında 1. grupta 4,38±0,23 mm, 2. grupta 4,43±0,36 mm, siklopentolat damlatıldıktan sonra ise 1. grupta 4,56±0,28 mm, 2. grupta 4,61±0,31 mm olarak bulundu. Her iki grupta ameliyattan sonraki ortalama ÖKD, ameliyattan öncekine göre anlamlı düzeyde daha derindi. Her iki grupta yakın nokta akomodasyonu sırasında ve siklopentolat uygulamasından sonraki GİL hareketi arasında anlamlı fark yoktu. Tartışma: Akomodasyon sırasında siliyer kas kasılır ve kapsul yatağı genişleyerek GİL’in öne yer değiştirmesine olanak sağlayabilir. Fakat bu çalışmada genç psödofakik olgularda akomodasyona bağlı olarak, GİL’in ön arka eksendeki hareketinde farklılık yoktu.
