  1. Dr Harminder P. Singh MD Dr Priyanka Galhotra MD India Authors have no financial interest of any kind in the present study Comparative evaluation of intracameralMoxifloxacin and Cefuroxime in prevention of endophthalmitis in surgical outreach camps in India.

  2. Out reach camps in developing countries- Why we need intracameral antibiotics? • Bulk surgeries. • Preoperative screening and preparation a challenge. • Intraoperative factors e.g instrumentation, irrigating fluids,IOL etc. always a threat. • Postoperative care and medications are always doubtful because of socio-economic factors. Intracameral route is more preferred : • Immediate, high antibiotic levels above MIC that are sustained for a period of time. • Less chances of bacterial resistance development • Results of the European Society of Cataract & Refractive Surgeons study – A nearly 5-fold decrease in postoperative endophthalmitis in patients who received intracameral injection of antibiotic.

  3. Purpose To compare the effectivity and safety of intracameral Moxifloxacin and Cefuroxime in prevention of endophthalmitis during surgical outreach camps. Moxifloxacin- Available as preservative free 0.5% solution with a ph of 6.8 and osmolality of 290 mOsm/kg Cefuroxime –Available as 500mg injection vials which need fresh reconstitution on the day of surgery. Final solution has a ph of 7.4 and osmolality of 311 mOsm/kg *Aqueous pH is 7.4, Osmolality 305mOsm/kg ** Intracameral injection of moxifloxacin is an off label use.

  4. Non-randomized retrospective study No. of cases- 336 { 306 patients} Place of study- Surgical outreach camps in northern India. Routine outreach camp protocol: Basic examination and screening is done at some area of need having difficult access to proper healthcare. After screening procedure patients are transported to main hospital for surgery. Assistance of various NGOs is sought for out of hospital activities. Study patients divided into 2 groups Group 1 – Cefuroxime group {done in 2006} Group 2 – Moxifloxacin group { done in 2007} Methods

  5. Methods • Day care surgery • Preoperative assessment – General physical examination Ocular examination- - Visual acuity - Nucleus grading { LOCS 3} - Endothelial cell counts* - Fundus { 90D Examination} - IOL work-up *Specular microscope was used for the purpose of present study only. It is not a part of routine screening in outreach camps

  6. Methods • Preoperative prophylaxis- • Topical Gatifloxacin 2 times one hour before surgery. • Eye lash trimming and Povidone-Iodine paint after peribulbar anesthesia. • Repeat Povidone-Iodine application in conjunctival sac immediately before draping the eye. • Intraoperative measures • Phacoemulsification in all cases {stop and chop technique} • PMMA lens implantation with one 10-0 nylon suture in all cases. • In the bag injection of antibiotic through side port at the end of surgery. Cefuroxime – 1mg/ 0.1 ml.* Moxifloxacin – 0.5mg/0.1 ml.** *Fresh solution was prepared on each surgery day. ** 0.1 ml solution was used from a commercially available preservative free Moxifloxacin.

  7. Methods Postoperative assessment • Day – 1 Wound integrity, corneal clarity, AC reaction* • Day -7 Visual acuity, AC reaction* • Day – 30 Best corrected visual acuity, endothelial cell counts, 90D fundus examination. Post-operatively all patients received topical Gatifloxacin and Prednisolone drops 5 times/day for 7 days and topical Prednisolone eye drops for 21days in tapering doses. *AC reaction- Hogan grading

  10. Discussion When do we need intracameral antibiotic? • Final decision is left to the treating ophthalmologist. • Cases where risk of infection is high • Clinics with high volume surgery • When wound construction is not satisfactory • Traumatic cataract cases with associated open globe injury • Associated surgical complications • Older patients >75 years { Higher bacterial contamination of conjunctiva} Which is better-Cefuroxime or Moxifloxacin ? Both have good safety profile and efficacy. Cefuroxime- - We have more experience with it. Moxifloxacin- - Broad spectrum - Easy availability - Preservative free

  11. Conclusion • Intracameral injection of Cefuroxime and Moxifloxacin both are equally safe and effective in prevention of post surgical endophthalmitis. • Intracameral injection of antibiotics can be considered in specific surgical situations. • Commercially available single dose units of antibiotics for intracameral injection can be a better alternative for time saving and maintaining sterility. • Continuing studies are desired in this direction to determine optimal doses of different antibiotics and changing trends in bacterial resistance.
