尊敬的编辑：目前，前房角粘连分离术（GSL）[1]、内小梁切开术、内巩膜丘脑切开术[2]和前房角切开术期间，前房角镜片必须压在角膜上，以防止空气进入前房角镜片和角膜之间的空间。这种压力会导致后弹力层的形成，使虹膜角膜角的视野变得模糊。为了克服这一点，我们修改了Swan-Jacobs透镜（Ocular Instruments，贝灵汉，WA，USA），以便在手术过程中可以获得虹膜角膜角的清晰视图。我们切下7号手术手套的小指，并将其修剪至约17 mm的长度。然后，我们偏心地切下指尖，以形成直径约为5 mm的圆形开口。然后在距离圆形开口边缘6.5 mm处开一个直径1 mm的孔（图1a）。将Swan-Jacobs透镜的手柄穿过该孔，将Swan-Jacobs透镜向上拉至指尖，将Swan-Jacob透镜周围的裙边修剪至4 - 5 mm。然后在距离手柄对面圆形开口边缘4 mm处的裙边上切出4 - 5 mm的切口（图1b）。
Dear Editor: At present, the goniolens must be pressed against the cornea to prevent air from entering the space between the goniolens and the cornea during goniosynechialysis (GSL)[1], trabeculotomy ab interno, sclerothalamotomy ab interno [2], and goniotomy. This pressure can cause Descemet’s folds that blur the view of the iridocorneal angle. To overcome this, we have modified the Swan-Jacobs lens (Ocular Instruments, Bellingham, WA, USA) so that a clear view of the iridocorneal angle can be obtained during surgery.For our modification, we cut the little finger of a size 7 surgical glove off and trimmed it to a length of about 17 mm. We then cut the tip of the finger off eccentrically to make a circular opening whose diameter was about 5 mm. Then a 1-mm-diameter hole was made 6.5 mm from the edge of the circular opening (Fig. 1a). The handle of the Swan-Jacobs lens was passed through this hole, and the Swan-Jacobs lens was pulled up into the tip of the finger, and the skirt around the Swan-Jacob lens was trimmed to be 4 to 5 mm. Then a 4 to 5-mm notch was cut in the skirt 4 mm from the edge of the circular opening opposite the handle (Fig. 1b).
