Successful Reposition of Prolapsed Silicone Tube Using Hole and Lacrimal Probe Method
Zee Yoon Byun,Bo Ram Lee,Sung Chul Kim 대한안과학회 2021 Korean Journal of Ophthalmology Vol.35 No.3
Purpose: Silicone tube intubation is the most common method for treatment of nasolacrimal drainage disorder or repair of lacerated canaliculus. However, some cases are prolapsed earlier than expected, subsequently affecting the success rate of silicone tube intubation. The author introduced a successful reposition of the prolapsed silicone tube. Methods: This study is a retrospective case series of 11 patients who were treated with reposition of prolapsed silicone tube using hole and lacrimal probe method. In all cases, the tubes were prolapsed within 2 months after the first surgery due to careless rubbing of the medial canthus by the patient. In all 11 cases, the development of a biofilm on tube was not observed at the time when the tube was prolapsed. All patients underwent immediate reposition of prolapsed tube without local anesthesia in the outpatient operating room on the day they visited. Results: In all 11 cases, the prolapsed silicone tube was repositioned without any complications using this hole and lacrimal probe method. At 6-month follow-up examination, all patients presented with a well-positioned silicone tube up to the day of extubation without replacing it with a new silicone tube. Conclusions: This hole and lacrimal probe method is effective for the repositioning of prolapsed silicone tube after bicanalicular intubation of lacrimal system. This procedure includes easy performance in a short time and without local anesthesia in the outpatient operating room.

유리체절제술 및 백내장수술을 시행한 군과 백내장수술만 시행한 군의 장기 수술 유발 난시도 비교
변지윤(Zee Yoon Byun),이정현(Jung Hyun Lee),이상목(Sang-Mok Lee),황덕진(Duck-Jin Hwang) 대한안과학회 2021 대한안과학회지 Vol.62 No.8
목적: 유리체절제술 및 백내장수술을 함께 시행한 환자와 백내장수술만 시행한 환자에서 수술 유발 난시의 장기 변화를 비교해 보았다. 대상과 방법: 백내장수술만 받은 군(1군)과 23게이지 무봉합 유리체절제술 및 백내장수술을 함께 시행 받은 군(2군)에서 술 후 1년간 수술 유발 난시의 변화를 후향적으로 비교하였다. 수술 전과 수술 후 1, 3, 6, 12개월 각각 자동각막곡률계검사를 이용하여 편평한 축 및 가파른 축의 각막곡률과 난시축을 측정하였다. 벡터분석법을 이용하여 수술 후 수술 유발 난시를 계산한 후 각 경과 관찰 시점별 값이 두 군 간 차이가 있는지 알아보았다. 결과: 총 86명 86안이 본 연구에 포함되었고 1군은 45안, 2군은 41안이었다. 수술 후 1, 3, 6, 12개월 경과 관찰 시의 수술 유발 난시 평균 값(diopter)은 1군에서 0.83 ± 0.37, 0.69 ± 0.39, 0.60 ± 0.33, 0.59 ± 0.33이었고, 2군에서 0.82 ± 0.47, 0.69 ± 0.38, 0.62 ± 0.28, 0.61 ± 0.30이었으며 시간 경과에 따라 수술 유발 난시는 두 군 모두에서 감소하는 추세를 보였다(모두 p<0.001). 각 경과 관찰 시점마다 두 군의 수술 유발 난시는 서로 유의한 차이를 보이지 않았다(모두 p>0.05). 결론: 유리체절제술 및 백내장수술을 함께 시행한 경우의 수술 유발 난시는 백내장수술만 시행한 군과 차이가 없었고, 이를 통해 23게이지 무봉합 유리체절제술이 각막난시에 유의한 영향을 주지 않음을 알 수 있었다. Purpose: To compare the long-term changes in surgically induced astigmatism (SIA) in patients who underwent 23-gauge sutureless vitrectomy and cataract surgery together with patients who underwent cataract surgery only. Methods: We retrospectively reviewed SIA changes for 1 year after surgery in patients who received only cataract surgery using phacoemulsification (group 1) and patients who underwent 23-gauge sutureless vitrectomy and cataract surgery together (group 2). Flat keratometry (K1), steep keratometry (K2), and astigmatism axis were measured with automatic keratometry before and after the surgery. Vector analysis was used to calculate SIA at 1, 3, 6, and 12 months postoperatively. We then examined whether the SIA values at each time point were different between the two groups. Results: A total of 86 eyes were included in this study (group 1, n = 45; group 2, n = 41). The mean SIA values calculated at 1, 3, 6, and 12 months after surgery in group 1 were 0.83 ± 0.37, 0.69 ± 0.39, 0.60 ± 0.33, and 0.59 ± 0.33, respectively. In group 2, the values were 0.82 ± 0.47, 0.69 ± 0.38, 0.62 ± 0.28, and 0.61 ± 0.30, respectively. Over time, SIA decreased in both groups (all p < 0.001). There was no significant difference in the mean SIA between the two groups at each follow-up time point after surgery (p = 0.296, p = 0.728, p = 0.361, and p = 0.356, respectively). Conclusions: When 23-gauge sutureless vitrectomy and cataract surgery were performed together, the astigmatism change caused by surgery did not show a significant difference compared with that of the group who received cataract surgery only. Thus, 23-gauge sutureless vitrectomy may not significantly affect corneal astigmatism.
