ABSTRACT
Objective: To evaluate the results of photorefractive keratectomy [PRK] with mitomycin C in myopia correction after five years
Methods: This is a cross sectional study which included 145 eyes of 74 patients in 18 to 51 years age group that were undergoing Photorefractive keratectomy with mitomycin C using Allegretto Wave Eye-Q 400-Hz excimer laser platform in Markazi Eye Center, Tehran, Iran. All the surgical procedures were performed by the same surgeon. After five years follow-up evaluation including BCVA, UCVA, Refractive error measurement and external eye examination was performed
Results: The mean diopter of spherical equivalent before surgery was -3.40 +/- 1.73. The following findings were obtained after 5 years follow up visit: The mean spherical equivalent value: -0.08 +/- 0.40, the mean Log MARUCVA: 0.02 +/- 0.07, the mean Log MAR BCVA: 0.00 +/- 0.04
Conclusion: PRK is an effective, safe and predictable method used to correct myopia. The wave frontoptimized algorithm of the Allegretto Wave Eye-Q 400-Hz excimer laser platform demonstrated good refractive and visual results. Presence of variables such as gender, age and astigmatism before operation have no significant impact on the result of this operation
ABSTRACT
Objective: Although computer technologies are now widely used in medicine, little is known about its use among medical students in Iran
The aim of this study was to determine the competence and access to computer and internet among the medical students
Methods: In this descriptive study, medical students of Shahid Sadoughi University of Medical Science, Yazd, Iran from the fifth years were asked to answer a questionnaire during a time-tabled lecture slot
The chi-square test was used to compare the frequency of computer and internet use between the two genders, and the level of statistical significance for all test was set at 0.05
Results: All the students have a personal computer and internet access
There were no statistically significant differences between men and women for the computer and internet access, use wireless device to access internet, having laptop and e-mail address and the difficulties encountered using internet
The main reason for less utilization of internet was slow speed of data transfer
Conclusions: Because of the wide range of computer skills and internet information among medical students in our institution, a single computer and internet course for all students would not be useful nor would it be accepted
