To define the use of modified bandage-contact-lens as a guide-marker for performing continuous-curvilinear-capsulorhexis by a first-year-post-graduate-ophthalmology-resident.
Phacoemulsification has now become the standard cataract surgery in which anterior capsulorhexis is the first and most crucial step. A perfect capsulorhexis is difficult to learn and even more difficult to master with a steep learning curve when performed free-hand especially by a first-year post-graduate ophthalmology-resident. There is paucity of simple, single-use, easily portable, cost-effective and affordable devices designed especially for performing CCCs in a safe and reproducible way.In our technique, the bandage contact lens (BCL) is trephined using a 6mm corneal trephine. After topical or peribulbar block (as the case may be), the 6mm-guide-marker (trephined BCL) is placed on the cornea. The CCC is then completed using the edge of the contact-lens as a guide for CCC.
AND IMPORTANCE: CCC with contact-lens-guide-marker is expected to yield better results in carrying out the procedure more accurately being closer to the target in terms of size, circularity and centration as compared to contact-lens-unassisted conventional CCC. This would eventually facilitate better surgical outcomes and we recommend this to be applied as the standard protocol for first-year post-graduate ophthalmology-resident performing the surgery.
确定改良绷带式隐形眼镜作为一年级眼科研究生进行连续环形撕囊引导标记物的用途。
超声乳化术现已成为标准的白内障手术,其中前囊撕囊是第一步也是最关键的步骤。完美的撕囊术很难学习,尤其是由一年级眼科研究生徒手操作时,由于学习曲线陡峭,掌握起来更是困难。专门设计用于以安全且可重复的方式进行连续环形撕囊的简单、一次性、便于携带、经济高效且价格合理的设备很少。在我们的技术中,使用6毫米角膜环钻对绷带式隐形眼镜(BCL)进行环钻。在局部或球周阻滞(视情况而定)后,将6毫米引导标记物(环钻后的BCL)放置在角膜上。然后以隐形眼镜边缘作为连续环形撕囊的引导完成撕囊。
与无隐形眼镜辅助的传统连续环形撕囊相比,使用隐形眼镜引导标记物进行连续环形撕囊预计在更准确地执行该操作方面能产生更好的结果,在尺寸、圆形度和中心定位方面更接近目标。这最终将有助于获得更好的手术效果,我们建议将其作为一年级眼科研究生进行手术的标准方案应用。
