Data were analyzed by SPSS₁₈ using Mann-Whitney and Chi-Square tests.<br> <strong>Results</strong>: Pre-surgery consultation unit startup was able to significantly reduce the patient waiting time before surgery (P-value < 0.001). No significant change was observed in cancellation rate and length of stay after the pre-surgery consultation unit startup (P-value > 0.05).<br> <strong>Conclusion</strong>: Considering the reduction of patients&#39; waiting time as one of the key indicators in eye surgery, preoperative consultation process and other effective processes should be improved to maximize benefits of establishing a preoperative consultation unit at Farabi Hospital.<br> &nbsp; Preoperative counseling, Quality, Waiting time, Cancellation of surgery, Patient 244 249 http://jebhpme.ssu.ac.ir/browse.php?a_code=A-10-146-1&slc_lang=en&sid=1 Seyed Jamalaldin Tabibi No Department of Health Care Management, Science and Research Branch, Islamic Azad university, Tehran, Iran Mohammad Reza Maleki No Department of Health Care Management, School of Health Management and Information Sciences, Iran University of Medical Sciences, Tehran, Iran Jamil Sadeghifar https://orcid.org/0000-0002-9422-7403 No Department of Health Education, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran Reyhaneh Sharifi Rhn_sharifi@yahoo.com https://orcid.org/0000-0003-0317-5917 Yes Razi Hospital, Tehran University of Medical Sciences, Tehran, Iran
