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.

The burden of intravitreal injections has increased tremendously over the past few years. Since traditionally the operation theatre setup is currently used for this procedure, it is increasingly becoming difficult to manage such a patient load in the theatres. To overcome this challenge, office-based setup for intravitreal injection was started. This study was planned to determine the incidence of endophthalmitis after office-based intravitreal bevacizumab injection and to compare it with previously reported incidence of endophthalmitis after operation theatre-based intravitreal injections. The study was conducted at Al-Ehsan Eye Hospital, Lahore, Pakistan, from July 2015 to June 2016, and comprised patients who received intravitreal injections of bevacizumab (Avastin) for different ocular indications. A total of 1,047 intravitreal injections were given in an office-based set-up. Of them, 2(0.19%) cases of clinically suspected endophthalmitis were identified. Office-based set-up for intravitreal bevacizumab injection was found to have comparable safety profile with traditional operation theatre-based set-up.
