We herein describe the kissing MVR technique in cases of microspherophakia for safe and effective endocapsular lens aspiration. Microspherophakia is associated with abnormally lax and broken zonules, which pose a great challenge to the operating surgeon, especially while creating the openings in the capsular bag. In this novel technique, simultaneous use of two 23 G MVR blades reduces the above problem associated with the severely mobile lens. Here, one MVR blade stabilizes the capsular bag and, at the same time, provides counter-traction for the opposite MVR blade while puncturing the capsular bag. Furthermore, the creation of openings in the lens at the equator or just posterior to it is beneficial as the capsule is relatively thicker and stronger at this location. This also minimizes the risk of premature extension to the anterior or posterior capsule, thereby avoiding complications like dropped lens matter, vitreous prolapse, and vitreous traction.
我们在此描述了微球形晶状体病例中用于安全有效进行囊内晶状体抽吸的亲吻式 MVR 技术。微球形晶状体与异常松弛和断裂的悬韧带有关，这对手术医生构成了巨大挑战，尤其是在囊袋中创建开口时。在这种新技术中，同时使用两个 23G MVR 刀片可减少与严重移动晶状体相关的上述问题。在这里，一个 MVR 刀片稳定了囊袋，并在刺穿囊袋时为对面的 MVR 刀片提供反向牵引。此外，在晶状体赤道或稍后方处创建开口是有益的，因为此处的囊袋相对较厚且较强。这也最大限度地降低了前囊或后囊过早延伸的风险，从而避免了晶状体物质脱落、玻璃体脱出和玻璃体牵引等并发症。
