Abstract:
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.
Insights
This study introduces the kissing MVR technique for safe lens aspiration in microspherophakia. The method uses two blades to stabilize the capsular bag, preventing complications during surgery.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Microspherophakia presents surgical challenges due to lax zonules.
- Creating openings in the capsular bag is difficult in these cases.
Purpose of the Study:
- To describe a novel "kissing MVR technique" for safe and effective endocapsular lens aspiration in microspherophakia.
- To address challenges posed by lax zonules and mobile lenses during capsular bag opening.
Main Methods:
- Simultaneous use of two 23-gauge microvitrector (MVR) blades.
- One MVR blade stabilizes the capsular bag, providing counter-traction for the other.
- Incisions are made at or posterior to the lens equator.
Main Results:
- The technique effectively stabilizes the capsular bag and the lens.
- Minimizes risk of premature capsular extension.
- Avoids complications such as dropped lens matter and vitreous prolapse.
Conclusions:
- The kissing MVR technique offers a safe and effective approach for endocapsular lens aspiration in microspherophakia.
- This method enhances surgical control and reduces the risk of intraoperative complications.
