| Summary: | AIM: To investigate the main factors that affecting the positive rate of bacterial culture before the intraocular lens implantation. <p>METHODS:Conjunctival sac specimen form senile patients, who received cataract crystal implantation from December 2010 to December 2012 in our hospital, were collected and cultivated at the following 3 time points: on admission day, after the eye-drops and after the surgical eye preparation. Afterwards, a comparative analysis was made in terms based on of the following factors: age, gender, dominant eye, occupation, days for eye-drops as well as the intervention techniques. <p>RESULTS: Factors such as age, gender, intervention technique were significantly related with the rate of bacterial culture, while factors such as occupation, dominant eye and days for pre-operative eye-drops had few effects on the final results. <p>CONCLUSION: There are both internal factors and external factors affecting the bacterial culture. Inconjunctival sac intervention techniques play a crucial role in the bacterial culture in conjunctival sac, which deserves more attention.
