Abstract
PURPOSE
To evaluate the learning curve of continuous curvilinear capsulorhexis (CCC) and to assess the number of surgeries required to master it among residents in a postgraduate teaching institute.
METHODS
The present prospective observational study was based on the completion time and complication rates related to CCC performed using various techniques by 10 students in the 2nd (JR2) and 3rd-year (JR3) of residency. CCC was performed either by a cystotome or capsulorhexis forceps or by a combined method in 253 eyes, of which 160 eyes (63.2%) were operated by JR3 and 93 (36.8%) by JR2. The complication rates were studied with respect to the number of capsular extensions, posterior capsular rent (PCR), zonular dehiscence, need for senior surgical assistance, and nucleus drop.
RESULTS
The average time required for the completion of CCC was 412 ± 90.5 s. The average number of times residents required to fill the anterior chamber with viscoelastic was 6.9 ± 1.4. The average size of CCC was 7 ± 0.66 mm. Extended CCC was the most common complication. JR2 required assistance from a senior surgeon in 47 eyes (50.5%), whereas JR3 required assistance in 39 eyes (24.4%) (P = 0.0001). The rate of PCR was not significantly different in JR2 (7.5%) and JR3 (8.8%).
CONCLUSION
CCC is a difficult step to master in the trainee. Focusing and practicing on this step will help to reduce the complications and maximize proficiency. Approximately 6-eight surgeries are required to master CCC.
