Purpose
To analyze the timing of anterior capsule tear outs in intumescent cataracts from the point of contact with a capsulotomy instrument to when the capsulorrhexis extends beyond the pupillary margin and compare it to femtosecond capsulotomy speeds.
Methods
This is a retrospective study in which 11 cases of anterior capsule tear outs in intumescent cataracts were selected; 4 of which were from our institution, 4 from published videos in peer reviewed literature, and the remaining 3 from online published videos. Using slow motion videography, we analyzed all recent cases of anterior capsule tear outs in intumescent cataracts at our institution and perused peer-reviewed literature for capsular tear outs in intumescent cataracts. Average time for tear outs were recorded using an embedded timer.
Results
The average tear out time for the 11 cases was 12.95 +/- 10.05 and the average time for tear outs at our institution was 3.88 +/- 2.50 seconds. The fastest recorded tear out occurred within 1.53 seconds, whereas femtosecond laser capsulotomy can be performed in 1.1 seconds
Conclusion
The average time for capsular tear out was not instantaneous and even the fastest observed tear out was slower than the time that it takes to perform a femtosecond laser capsulotomy, which may be considered as an alternative approach to the intumescent cataract
