After-cataract evaluation after using balanced salt solution, distilled deionized water, and 5-fluorouracil with a sealed-capsule irrigation device in the eyes of 4-week-old rabbits.
OBJECTIVE
To evaluate the Perfect Capsule sealed-capsule irrigation device (Milvella Pty., Ltd.) using 3 substances in young rabbit eyes.


METHODS
St. Erik's Eye Hospital, Stockholm, Sweden.


METHODS
Thirty 4-week-old rabbits had clear lens extraction in both eyes. In 1 randomly selected eye, the Perfect Capsule was applied and the lens capsule was irrigated for 5 minutes with 1 of 3 substances: balanced salt solution (BSS), distilled deionized water (DDW), or 5-fluorouracil (5-FU) 50 mg/mL. In the other eye, no sealed capsule irrigation was used. Forty days postoperatively, the animals were killed and the eyes fixed in formalin for histologic analysis. After-cataract was evaluated in 3 ways: clinically, from photographs, and histologically. Central posterior capsule thickness was evaluated using a microscope, camera, and computer.


RESULTS
The Perfect Capsule sealed-capsule irrigation system could be used in all selected eyes. The vacuum to the anterior capsule was tight, and the system was sealed in all eyes. After-cataract developed in the BSS group and DDW group, but not in the 5-FU group. The 5-FU group had significantly less after-cataract than the other 2 groups (P<.05). There was no difference between the groups in capsule thickness.


CONCLUSIONS
The Perfect Capsule sealed-capsule irrigation system could be used in small eyes. Distilled deionized water did not prevent after-cataract in rabbit eyes with highly proliferative cells, but 5-FU was effective in preventing after-cataract.
