人工晶体眼大泡性角膜病变的穿透性角膜移植

The Penetrating Keratoplasty for the Pseudophakic Bullous Keratopathy

目的:研究人工晶体眼大泡性角膜病变行穿透性角膜移植的临床效果和保留或取出原人工晶体的适应证。方法:应用穿透性角膜移植治疗人工晶体植入术后大泡性角膜病变。结果:13例(13眼),术中保留原人工晶体11眼,取出原人工晶体2眼。术后随访平均16个月。随访期间角膜移植片全部透明,术后绝大部分病例视力获得提高,其中视力矫正达到0.2以上有5眼。结论:穿透性角膜移植是治疗人工晶体植入术后大泡性角膜病变有效方法。只要人工晶体位于囊袋内,位置正常,术中应保留原人工晶体,手术安全,术后视力恢复良好。眼科学报1998;14:227～228。

Purpose:To investigate the clinical effectiveness of penetrating keratoplasty for pseu-dophakic bullous keratopathy and the indication for keeping or removing intraocular lens. Methods : 13 cases(13 eyes)of pseudophakic bullous keratopathy were treated by penetrating keratoplasty. Rsults: The intraocular lens were kept in 11 eyes and were removed in 2 eyes during operation,The average follow-up time was 16 months. All corneal grafts remain transparent, Visual acuity of most cases were improved,The best-corrected visual acuity of 5 eyes was 0.2 or better. Conclusion : The penetrating keratoplasty is an effective treatment for the pseudophakic bullous keratopathy. It should be kept if intraocular lens is in nomal position and located in lens capsule,and it is helpful for safety of the surgery and improvement of visual acuity. Eye Science 1998 ; 14 :227 - 228.
