This document summarizes a retrospective study analyzing 84 cases of post-operative endophthalmitis following cataract surgery over 5 years. The study evaluated the effectiveness of the "Abou Shousha Triple Procedure" with and without vitrectomy. The Triple Procedure involves intravitreal and intracameral antibiotic injection along with removal of anterior chamber membranes. For patients presenting with light perception or worse, vitrectomy was also performed. The majority of cases saw visual improvement. The study concluded the Triple Procedure, with or without vitrectomy based on initial vision, is an effective treatment for post-operative endophthalmitis.

25. Conclusion
• Abou Shousha Triple Procedure may be
considered an effective modality of the
treatment of post-operative endophthalmitis
with or without Vitrectomy according to the
visual acuity of the patient on presentation.

26. • Cases presented with hand motion or
better visual acuity are treated with
The Triple Procedure without
Vitrectomy
• Cases presented with light perception
visual acuity are treated with the Triple
Procedure plus parsplana Vitrectomy
• Even in the additional procedure The
Triple Procedure should be considered
