Customized disposable kit versus a conventional stainless steel instrument for an intravitreal injection: A comparison.

Comparison of a customized disposable kit with a conventional stainless steel instrument was performed for an intravitreal injection. A total of 2700 eyes of 2250 patients were enrolled in two groups. Comfort level of the patients was assessed using a 'Pain Scale' and any post intravitreal injection complications were examined clinically by a slit lamp biomicroscopy. Surgeon's ease was assessed by a questionnaire. In group A, no pain was recorded in 1231(82.06%) eyes, mild pain was d escribed in 184(12.27%), moderate pain was documented in 78 (5.2%) while, severe pain was noticed in 7(0.47%). In group B, no pain was seen in 1014(84.5%), mild pain was present in 123(10.25%), moderate pain was perceived in 58 (4.83%) while, severe pain was recorded in 5 (0.42%). With respect to surgeon's ease, 6 out of the 7 surgeons found the kit to be more convenient and cost effective as compared to the conventional instruments. Disposable intravitreal kit is beneficial for both the patients as well as the surgeons.
