Purpose: Explore the possibility of the OPESAVER in small-incision Ozil sleeve cataract surgery.

Method: To confirm the efficacy of this tool, we did an experiment using porcine eyes, aimed at measuring internal pressure of anterior chamber. We changed the height of the bottle a step at a time and tested pressure for 40 seconds with and without the OPESAVER at each height.

Results: Bottle height is 90 cm and the OPESAVER is not attached. Variance is extreme between the maximum 100 mmHg and a minimum 22 mmHg. Overall, intraocular pressure is clearly unacceptably unstable. Here bottle height is again 90 centimeters but the OPESAVER is attached. Variation in pressure is much better 79.5 mmHg maximum 40.5 mmHg minimum. Even using a tool with a high surge risk such as an Ozil and a bottle height as low as 60 centimeters the OPESAVER prevents instability in the anterior chamber, improving the safety of the operation.

Conclusion: The Ozil is excellent if the priority is efficiency. But from the point of safety and patient satisfaction as priorities, it is not enough. OPESAVER offers the best of all possible stages since you can use a low bottle height and maintain the stability of the anterior chamber.
