Comparative Study
Efficacy of topical povidone-iodine during the first week after ophthalmic surgery.
In the first postoperative day, povidone-iodine ophthalmic solution prevents an increase in conjunctival bacterial colony-forming units and decreases the species compared with antibiotic. We sought to determine whether these beneficial effects of povidone-iodine could be sustained during the first postoperative week. ⋯ Povidone-iodine ophthalmic solution is an alternative to postoperative topical antibiotics because of its effectiveness in controlling conjunctival bacterial colony-forming units and species, its relatively low cost, and its availability.

Comparative Study
Blinking is controlled primarily by ocular surface conditions.
To investigate the relation between blinking and ocular surface conditions and to introduce and examine a new index, the maximum blink interval. ⋯ There was an important association among blink rate, maximum blink interval, and ocular surface conditions. The blink rate and our newly introduced measurement, the maximum blink interval, should prove useful in assessing factors that cause dry eye. This prospective study should contribute to the understanding and treatment of dry eyes.
