Abstract

Purpose: To investigate the effectiveness and reliability of the stretch pupilloplasty technique in cases which pupil can not be dilated with pharmacologic methods preoperatively. Material and Method: The patients were examined in three groups. In Group I, 19 eyes of 16 patients in whom pupil could not be dilated preoperatively (smaller than 4 mm) and phacoemulsification performed without intervention to pupil was evaluated. In Group II, small pupils were dilated with pupil stretching maneuvers in 19 eyes of 16 patients and in Group III, 19 eyes of 17 patients were evaluated as control group in which phacoemulsification was performed without pupil problem. The groups were harmonious statistically according to age, sex, laterality of the eyes, cataract density, preoperative visual acuity and follow-up period. Results: In Group I, II and III, mean phaco time was 1.96±1.33, 1.18±0.43 and 1.09±0.48 minutes and mean effective phaco time was 21.62±13.11, 12.84±5.88 and 10.58±5.27 seconds respectively. Group I was statistically different from Group II and III according to both values (p<0.05, p<0.01 and p<0.01, p<0.01) and there wasn't difference between Groups II and III (p>0.05 and p>0.05). Difference was not seen according to intraoperative complications (hemorrhage, iris damage and posterior capsule rupture) and postoperative complications (anterior chamber reaction, fibrillary membrane formation, corneal edema and intraocular pressure increase) (p>0.05). Postoperative pupil evaluation according to following three categories; 'esthetic and functional', 'esthetic but not functional' and 'irregular' showed no difference between groups (p>0.05). Achieved postoperative visual acuity was not different between groups (p>0.05). Conclusion: Pupil stretching technique, in eyes which pupil can not be dilated more than 4 mm, makes the operation easier and diminishes the phaco time and effective phaco time. In spite of this, it doesn't make up any difference according to intraoperative and postoperative complications

Özet

Amaç: Ameliyat öncesinde farmakolojik yöntemlerle pupillası genişletilemeyen olgularda kullanılan "germe pupiloplasti (=stretch pupiloplasty) yönteminin etkinlik ve güvenilirliğini araştırmak. Gereç ve Yöntem: Hastalar 3 grupta ele alındı. Birinci grupta ameliyat öncesi pupillası genişlemeyen (4mm.'den az) ve pupillaya müdahale olmadan ameliyatları gerçekleştirilen 16 hastanın 19 gözü, 2. Grupta küçük pupillaları, ameliyat sırasında pupiller germe manevrası ile genişletilen 16 hastanın 19 gözü, 3. Grupta da pupiller sorunu olmaksızın ameliyatları gerçekleştirilmiş olgulardan rastgele seçilmiş 17 hastanın 19 gözü kontrol grubu olarak yer aldı. Gruplar yaş, cins, lateralite, katarakt sertliği, pre-operatuar görme keskinliği, takip süreleri yönünden istatistiksel olarak uyumlu idi. Bulgular: Ameliyat değerleri irdelendiğinde, ortalama fako zamanı gruplarda sırasıyla, 1.96 dk. (±1.33), 1.18 dk. (±0.43), 1.09 dk. (±0.48) ve ortalama etkili fako zamanı ise 21.62 sn. (±13.11), 12.84 sn. (±5.88), 10.58 sn. (±5.27) bulundu. Her iki değer için de 1.Grup istatistiksel olarak, 2. ve 3. Gruplardan farklılık gösterdi (p 0.05) ve (p>0.05). Per-operatuar (hemoraji, iris hasarı, arka kapsül yırtılması) ve post-operatuar (ön kamara reaksiyonu, fibriler membran oluşumu, kornea ödemi, göz içi basıncı artışı) komplikasyonlar yönünden fark bulunmazken (p>0.05), post-operatuar pupilla değerlendirmesi; pupillanın estetik ve fonksiyonel, estetik ama fonksiyonel değil, ya da düzensiz, şeklinde 3 ayrı kategoride yapıldığında farklılık tanımlanmadı (p>0.05). Post-operatuar ulaşılan görme keskinlikleri ise gruplar arasında istatistiksel farklılık göstermedi (p>0.05). Sonuç: Pupillası ameliyat öncesinde 4mm.'den fazla genişletilemeyen olgularda, pupilla germe uygulaması, ameliyatı kolaylaştırmakta ve kullanılan fako zamanı ve etkili fako zamanını kısaltmaktadır. Buna karşın per-operatuar ve post-operatuar komplikasyonlar yönünden olumsuz bir farklılık getirmemektedir.
