This prospective, nonrandomized, consecutive and comparative study assessed 20 patients (40 eyes) who had bilateral cataract surgery performed using the IOLs described. Patients were divided into groups, bilateral trifocal implant and blended implant. Evaluation included measurement of binocular uncorrected and corrected distance visual acuity at 4 m (UDVA, CDVA) and uncorrected intermediate (60 cm) and near (at 40 cm) visual acuity; contrast sensitivity (CS) and visual defocus curve. Postoperative CDVA comparison showed no statistical significance between groups. UDVA was significantly better in the trifocal groups. Under photopic conditions, the trifocal group had...

A prospective study with random samples, performed at the Departments of Ophthalmology and Pathology of Santa Casa Misericórdia de São Paulo, in August of 2006. Eighty normal eyes of 40 healthy individuals were analyzed. Samples were collected in the right eye with a dry swab and stored in Stuart's medium, where all microbiological material is kept immersed in the medium and the tube is hermetically sealed. In the left eye, the conjunctival material was collected using a swab embedded in saline solution 0.9%, and stored in dry and sterile test tubes sealed with cotton. The samples were analyzed within 2 hours at most after collection. Out of 40 samples collected with wet swab and transported in dry tube, bacteria were observed in 10 (25%), whereas of 40 samples coll...

Patients were assigned randomly to three groups. Group 1 patients received a topical artificial tear substitute (placebo); group 2 received ketorolac tromethamine 0.4% (Acular LS, Allergan) and group 3 received nepafenac 0.1% (Nevanac, Alcon). The incidence and severity of CME were evaluated by retinal foveal thickness on optical coherence tomography (OCT) after 1, 4 and 12 weeks. One hundred and twenty-six eyes of 126 patients were included in this study. The between-group differences in visual outcomes, central corneal thickness and endothelial cell density were not statistically significant. In all retinal thickness measurements, an increase was detected starting from the postoperative first week until 12 weeks. There was no statistically significant difference between the three groups in...

This prospective comparative study included 78 eyes of 39 patients. The performed ophthalmologic evaluation included near, intermediate and distance corrected and uncorrected visual acuity, contrast sensitivity measurement (under photopic and mesopic conditions) and wavefront analysis with the OPD-Scan aberrometrer. Uncorrected near and distance visual acuity and aberrometry analysis were similar with both intraocular lenses; nevertheless, intermediate visual acuity and contrast sensitivity under photopic conditions were statistically better with Tecnis ZM900. Both studied intraocular lenses promoted excellent near and distance postoperative visual acuity, in high contrast situations. Tecnis ZM900 IOL provided good quality of vision with high contrast condition in low luminosity with reduction in spherical aberration and improvements in intermediate visual acuity when compared to Restor IOL.

A study performed in one center, simple masked, parallel-group compared ketotifen and olopatadine. These patients were evaluated on four visits during the treatment (days 1, 7, 14 and 21), defined by ratings scores. Adverse events were the main variable of safety rating. On evaluating ocular itching, burning, tearing, conjunctival hyperemia, mucous discharge and photophobia, the ketotifen group showed a significant improvement of total signs and symptoms (p<0.05). Between the baseline and the 2nd visit, treatment with olopatadine resulted in decreased burning, but after the 4th visit, ketotifen was slightly better. Sand sensation, papillae and Horner-Trantas dots were not significantly different in both groups. Both drugs were efficient and safe relieving the main symptoms and signs of vernal keratoconjunctivitis. Between the same timepoints, there was a significant difference in favor of ketotifen-treated patients (p<0.05), showing improvement of itching, tearing, conjunctival hyperemia, mucous discharge and photophobia.
