RESUMO
PURPOSE: To report posterior capsular opacification in acrylic intraocular lenses. METHODS: Retrospective review of notes of patients with cataract surgery involving implantation of a hydrophilic acrylic intraocular lens (IOL) (MDR SC-60B-0UV) in at least one eye. This was done as a retrospective audit for clinical risk following adverse event reports, regarding MDR SC-60B-0UV intraocular lens, were published. Data regarding the pre- and post-operative visual acuity, ocular co-morbidity, posterior capsular thickening, Nd-YAG capsulotomy, final visual acuity, and changes in the lens clarity in both eyes were noted from the clinical notes. RESULTS: 45 patients and 90 eyes were identified. Posterior capsular opacification (PCO) as determined by slit-lamp examination was 40% for the hydrophilic IOL (SC-60B-0UV) and 8% for the contra-lateral eye (hydrophobic IOL). In 22 eyes opacification of the SC-60-0UV IOL was observed at slit-lamp examination (44%). CONCLUSION: The hydrophilic acrylic IOL (SC60B-0UV) appears to have a high incidence of PCO.

INTRODUCTION: We report a rare case of Mycobacterium fortuitum affecting the corneal graft of a patient 6 years post-graft, possibly associated with contact lens use. CONCLUSIONS: This case shows the need for careful microbiological techniques when dealing with patients presenting with microbial keratitis. It must be kept in mind that unusual and slow growing organisms may also be responsible for corneal ulceration. If a slow growing organism is suspected, a microbiological diagnosis may not be forthcoming for weeks. Misidentification of the responsible pathogen may further complicate management for the clinicians. Cases such as these, which may not respond to medical therapy as expected, may prove a difficult therapeutic challenge to physicians.
