Abstract Details

Purpose:

To determine the importance of wet-lab training on sclerocorneal wound construction, by 1st year trainee residents, and surgically induced astigmatism thereof by manual small incision cataract surgery(MSICS).

Setting:

Retrospective, observational study at a single centre in coastal Odisha, India

Methods:

Data of 64 eyes operated for MSICS by residents were collected. They were divided into 2 groups. Group-A had 32 eyes wherein wound construction was performed by 1st year trainees with prior wet-lab experience. Group-B had 32 eyes in which wound construction was performed by 1st year trainees without wet-lab experience. Intervention by expert trainer , where required, had been undertaken. Information on type of incision, extent, complications during tunnel construction was obtained . Post-operative vision on day 1, 2 weeks and 4 weeks was obtained. Surgically induced astigmatism(SIA) as on 4 weeks post-op was obtained and noted.

Results:

Complications encountered were button-holing (Group-A -6.2%, Group-B - 15.6%) and premature entry(Group-A - 6.2%, Group-B - 12.5%). Frown incision had been performed by 37.5% in Group-A as compared to 9.4% in Group-B. Mean SIA was also found to be higher in Group-B as compared to Group-A (p<0.05).

Conclusions:

Proper wound construction is the first step to a complication-free MSICS. Hence it is important for 1st year trainee residents to undergo wet-lab training before proceeding to operate on human eye, so as to get better hand-eye co-ordination for carrying out the procedure.
