Accidental trauma involving the eye may necessitate surgical removal of the eye ball. Immediate management should consider future prosthetic rehabilitation. Insertion of eye ball implant after enucleation or evisceration preserves socket anatomy, maintains sulcus and fornix which ensures proper retention of ocular prosthesis in future. Placement of intraorbital ball implant also reduces the weight as well as enhances motility of the prosthesis, thus imparting life-like appearance. Custom-made acrylic prosthesis has been shown to deliver superior functional and esthetic result. Exact positioning of the iris disc on a custom-made scleral blank is critical from esthetic point of view. This clinical report describes prosthetic rehabilitation of an anophthalmic socket where intraorbital ball implant was inserted during evisceration. Custom-made acrylic ocular prosthesis with a prefabricated iris button was used. Here, digital photography and a specially fabricated spectacle gridded with mm scale were used for positioning iris button on the ocular prosthesis. These two methods of centration of iris button may be used to reduce chairside time and increase patient cooperation with a positive clinical outcome.
涉及眼睛的意外创伤可能需要手术摘除眼球。立即处理时应考虑未来的假体康复。眼球摘除或眼内容剜出术后植入眼球植入物可保留眼窝解剖结构,维持睑裂沟和穹窿,确保未来义眼假体的正确固定。眶内球植入物的放置还可减轻义眼重量并增强其活动度,从而呈现逼真外观。定制丙烯酸义眼已被证明能带来卓越的功能和美学效果。从美学角度来看,将虹膜盘精确放置在定制的巩膜坯料上至关重要。本临床报告描述了在眼内容剜出术中植入眶内球植入物的无眼球眼窝的假体康复情况。使用了带有预制虹膜纽扣的定制丙烯酸义眼。在此,利用数码摄影和专门制作的标有毫米刻度的眼镜来将虹膜纽扣定位在义眼上。这两种虹膜纽扣对中的方法可用于减少椅旁时间并提高患者配合度,从而获得良好的临床效果。
