Objective: To determine the in-vitro activity of voriconazole and compare it with amphotericin B, fluconazole, itraconazole, ketoconazole, and caspofungin against local yeast and mold clinical isolates Candida albicans, Candida sp., Aspergillus terreus, Aspergillus niger, and Fusarium cylindrocarpone. Methods: Review of the Institute of Ophthalmology microbiology records were done and was the basis for the local isolates included in the study. Mean inhibitory concentration (MIC) was determined using YeastOne Sensititre Microtitre Colorimery method (TREK Diagnostic Systems, England). Two-way ANOVA, Duncan, and Pearson chi-squared tests were used to analyze the data. Results: All isolates tested were sensitive to voriconazole. Eighty percent (80%) of the isolates were sensitive to amphotericin B and 25% showed resistance to itraconazole. Yeast pathogens were all sensitive to amphotericin B and voriconazole. More than 50% of the yeast pathogens were resistant to ketoconazole. Molds or filamentous fungi showed higher susceptibility to voriconazole than amphotericin B and the other antifungals. Conclusion Voriconazole exhibited good in-vitro activity against the isolates tested. It has the same efficacy on yeast pathogens (Candida albicans and Candida sp.) when compared with amphotericin B. It has superior efficacy on filamentous fungi (Aspergillus and Fusarium). There is a role for voriconazole in the treatment of ocular infections, especially in the setting of poor antifungal drug availability.

OBJECTIVE

Successful intraocular lens (IOL) placement in cataract surgery is synonymous with the IOL being placed in the capsular bag. When the capsular bag is violated, the ciliary sulcus becomes an option to approximate an inthe- bag position. Studies report that single-piece foldable acrylic (SPA) IOLs are a poor choice for the sulcus. This study aimed to report the visual outcomes and complications of sulcus placement of single-piece intraocular lenses and three-piece intraocular lenses, and compare the design and characteristics to the occurrences of complications.

The medical records of patients were retrospectively reviewed in a single center from 2016-2019.

A total of 245 eyes from 237 patients were included in the study with a mean age of 61 years and male predominance. Majority of sulcus implantation occurred during phacoemulsification (87%). Around 82% (n=202) were implanted with single-piece IOLs and 18% (n=43) were three-piece IOLs. Best corrected distance visual acuity (BCDVA) was 20/20 after six months for both groups. Comparison between two groups showed no superiority with each other. Complications notable were elevated intraocular pressure, corneal edema, loss of IOL centration, and pigment dispersion. Smaller optic diameter and overall length predispose to higher probabilities of loss of centration. Pliability, hydrophobicity/hydrophilicity, and material do not correlate with postoperative complications. There were significantly higher numbers of pigment dispersions in IOLs with square-edged design.

In conclusion, visual outcomes remain equally excellent for both single-piece and threepiece groups. In contrast, there were more notable complications in single-piece group. Loss of centration tends to occur more with mean optic diameters lower than or equal to 5.50 mm and an overall length of less than 12.50 mm or lower. While appropriate for the capsular bag, square-edged designs were found to be inappropriate for the sulcus. The retrospective design does not allow strong inferences hence caution should be taken in correlating results.
