Yeni Bir El Aleti Kullanarak Bimanuel Kapsüloreksis: Koyun Gözünde Deneysel Çalışma
Bu çalışma, katarakt cerrahisinde deneyimsiz ve deneyimli cerrahlar için kullanımı kolay, ucuz ve uygun şekil ve boyutta sentralize bir kapsüloreksis yapılabilmesine olanak tanıyan bir el aleti tasarlamak amacıyla yapıldı. Yerel bir mezbahaneden toplanan 45 ölü koyun gözü; grup 1, sürekli eğrisel kapsüloreksis (CCC) grubu (n: 15); grup 2, serklaj tel grubu (n: 15); ve grup 3, polilaktik asit (PLA) aleti grubu (n: 15) olarak ayrıldı. Grup 1’de bir korneal ensizyon yapıldı. Grup 2 ve 3’te, saat 3:00 ve 11:00 yönlerinde iki ensizyon yapıldı. Kapsül, metilen mavisi ile boyandı. Ön kamaraya viskoelastik enjekte edildikten sonra kapsül delindi, cihazlar saat 3: 00 yönünden yerleştirildi. Tüm kapsüloreksisler, cihazların iç kontürünü izleyen Utrata forsepsi kullanılarak gerçekleştirildi. Çalışma sonucunda, grup 1’deki 15 gözün 9’u, grup 2’deki 15 gözün 2’si; ve grup 3’teki 15 gözün 12’sinde kapsüloreksis başarıyla gerçekleştirildi. İstatistiksel olarak, grup 1 ve 2’nin (χ²=7.033, P=0.008); ve grup 1 ve 3’ün (χ²=6.171, P=0.002) dağılımları arasındaki korelasyon anlamlı bulundu. Bu çalışma, deneyimsiz cerrah tarafından yeni tasarlanmış PLA cihaz kullanılarak yapılan CCC’nin klasik yönteme göre daha başarılı olduğunu göstermiştir.
Bimanual Capsulorhexis Using a New Hand Tool: An Experimental Study in Sheep Eye
The purpose of this study was to design a cheap and easy-to-use hand tool that allows a better-centered capsulorhexis of consistent shapeand size for inexperienced and experienced surgeons in cataract surgery. Forty-five eyes of dead adult sheep from a local slaughterhousewere grouped as; group 1, the continuous curvilinear capsulorhexis (CCC) group (n: 15); group 2, the cerclage wire group (n: 15); and group3, the polylactic acid (PLA) hand tool group (n: 15). In group 1, one corneal incision was made. In groups 2 and 3, two incisions were made at3:00 and 11:00 o’clock directions. Methylene blue was used for capsular staining. After injecting viscoelastic into the anterior chamber andthe capsule was punctured, the devices were inserted at 3:00 o’clock. All capulorhexes were performed using the Utrata forceps following theinternal contour of the devices. As a result of the study, capsulorhexes were successfully performed in 9 of 15 eyes in group 1; 2 of 15 eyes ingroup 2; and 12 of 15 eyes in group 3. Statistically, the correlation between the distributions of groups 1 and 2 (χ²=7.033, P=0.008); and forgroups 1 and 3 (χ²=6.171, P=0.002) were found to be significant. This study showed that CCC was performed using the newly designed PLAhand tool more successfully than the classical method by the beginning surgeon
