OBJECTIVE
To compare the motility of scleral-covered hydroxyapatite and alloplastic enucleation implants.
DESIGN
Retrospective, nonrandomized comparative trial.
PARTICIPANTS
Measurements were obtained after surgery in 76 anophthalmic patients who had received either hydroxyapatite or alloplastic enucleation implants. METHODS/MAIN OUTCOME MEASURES: Horizontal and vertical excursions of the enucleation implants.
RESULTS
There is no clinically important difference between the movement of hydroxyapatite and alloplastic enucleation implants. Implant movement appears to decline with advancing age.
CONCLUSION
Scleral-covered alloplastic and hydroxyapatite enucleation implants show similar movement. Although directly coupling hydroxyapatite implants to the prosthesis via the motility peg provides enhanced prosthetic movement, there appears to be no motility benefit of nonpegged hydroxyapatite over spherical alloplastic implants.
目的
比较巩膜覆盖羟基磷灰石义眼座与异体材料眼球摘除植入物的活动度。
设计
回顾性、非随机对照试验。
研究对象
对76例接受羟基磷灰石或异体材料眼球摘除植入物的无眼球患者术后进行测量。
方法/主要观察指标：眼球摘除植入物的水平和垂直活动度。
结果
羟基磷灰石义眼座与异体材料眼球摘除植入物的活动度在临床上无显著差异。植入物的活动度似乎随年龄增长而下降。
结论
巩膜覆盖的异体材料和羟基磷灰石眼球摘除植入物活动度相似。虽然通过活动栓将羟基磷灰石义眼座直接与义眼连接可增强义眼活动度，但未使用栓子的羟基磷灰石义眼座与球形异体材料植入物相比，在活动度方面并无优势。
