    PURPOSE: To compare the efficacy of heparin-surface-modified (HSM), poly(methyl methacrylate) (PMMA) posterior chamber intraocular lenses (IOLs) with that of unmodified PMMA IOLs in reducing postoperative complications caused by inflammatory reactions after extracapsular cataract extraction in an Asian population.

    SETTING: Departments of Ophthalmology, University of Malaya, Kuala Lumpur, Malaysia, and Tan Tock Seng Hospital, Singapore.

    METHODS: In a randomized, double-blind study performed at two centers, 51 patients received an HSM PMMA lens and 48, an unmodified PMMA IOL. Cell and pigment deposits were evaluated by slitlamp at 1 to 6 days, 2 to 3 weeks, and 3 to 6 months postoperatively.

    RESULTS: Significantly more eyes with unmodified IOLs had inflammatory cell deposits than those with HSM IOLs at 3 to 6 months (P < .001) and 12 to 14 months (P = .018) postoperatively. The HSM group also had significantly fewer cell deposits per patient at these two follow-ups. Significantly more eyes in the non-HSM group had pigment deposits 3 to 6 months after surgery (P = .049). One year postoperatively, about 85% of patients in both groups had a best corrected visual acuity of 0.5 or better.

    CONCLUSION: Heparin surface modification significantly reduced the inflammatory response to PMMA IOLs in an Asian population for at least 12 to 14 months.

  2. Fulltext Role of intravitreal/intracameral antibiotics to prevent traumatic endophthalmitis - Meta-analysis

    Traumatic endophthalmitis is a devastating condition that can occur following an open globe injury and result in loss of vision. The use of prophylactic antibiotics is empirical as most surgeons fear complications associated with the same. No systematic review has been performed in English on the role of intravitreal/intracameral antibiotics in preventing traumatic endophthalmitis. We searched for randomized controlled trials and controlled clinical trials comparing intracameral/intravitreal antibiotics with placebos on PubMed, Google Scholar, Science Direct, and Cochrane Library using keywords open globe/trauma/penetrating/perforating injuries endophthalmitis. The last search was on 5 May 2017. We included patients of all ages with open globe injuries who received intracameral/intravitreal antibiotics, regardless of the dose. Quality of the trials was assessed using Cochrane collaboration tools to assess the risk of bias. The main outcome measures were endophthalmitis and visual acuity. We included three trials. Overall, intravitreal/intracameral antibiotics were noted to significantly reduce the occurrence of endophthalmitis in open globe injuries (relative risk [RR] 0.19, 95% confidence interval [CI] 0.06-0.57). The use of intravitreal/intracameral antibiotics did not have an effect in improving visual acuity (RR 1.17, 95% CI 0.61-2.23). Two trials (Narang 2003; Soheilan 2001) were observed to have no significant effect on visual acuity while another trial (Soheilan 2007) did not list visual acuity as part of its objectives. Intracameral/intravitreal antibiotics reduce the risk of endophthalmitis in open globe injuries; although, there was no improvement in the visual acuity. We, therefore, recommend the use of intravitreal/intracameral injections in open globe injuries to prevent this devastating complication.
