Purpose:
To report the selection procedure of complicated and uneventful cataract extractions included in the Swedish Capsule Rupture Study and to describe the additional care required after a capsule complication during cataract surgery.
Setting:
Ten ophthalmic surgery departments in Sweden.
Methods:
Consecutive cataract extractions with a reported capsule complication were selected from the national database. Surgical data and data from the matching ophthalmic records at the participating clinics were analyzed. Controls were selected as the first uneventful procedure in the database after each procedure with a complication.
Results:
Data on 655 cataract extractions were studied for evaluation of risks and additional care; a capsule complication occurred in 324 procedures and no complication in 331 procedures. Using these records, 369 patients were recruited for a follow-up examination of the outcomes 3 years after the original cataract extraction. The records showed a substantial increase in additional care after a capsule complication, including more visits after surgery, increased need for in-patient care, and a significantly greater percentage of reoperations than after the uneventful surgery. With additional care, the average cost of a procedure with a capsule complication was approximately double the cost of an uneventful cataract extraction.
Conclusions:
The combined study of the database and matching medical records showed a substantial increase in additional care after a capsule complication. Using the database allowed identification of a large number of capsule complication cases and uneventful cases, indicating that national databases are excellent sources of data for studying unusual complications.
