Clinical Study on Factors Associated with Recurrence and Reoperation in Intermittent Exotropia

PURPOSE: The purpose of this study is to analyze factors associated with recurrence and reoperation in intermittent exotropia. METHODS: The medical records of 285 patients who had undergone the bilateral lateral recti recessions for intermittent exotropia with at least 1 year of postoperative follow-up were reviewed retrospectively. Surgical success was defined as a final deviation less than 10PD, overcorrection more than 10PD and recurrence less than 10PD at postoperative 3 months but recurring later, so being exodeviated more than 10PD in primary gaze at postoperative 1 year. Reoperation was performed when the eye was excessively exodeviated with follow-up, requiring surgical revision clinically. We investigated factors associated with recurrence, comparing recurrence group to success group, and also investigated factors associated with reoperation, comparing reoperation group to recurrence group. RESULTS: Alignment at postoperative 1 day was proved to be significant factor influencing on recurrence. The age at the time of operation, preoperative alignment, stereopsis, etc were not associated with recurrence. Also, stereopsis was associated with reoperation, but there were no relationship between reoperation and other factors. CONCLUSIONS: Alignment at postoperative 1 day was related to recurrence and poor stereopsis (> or =400 sec) was associated with reoperation. Therefore, sensory function, such as stereopsis should be considered more important than motor control when considering reoperation.

2005 Survey for KSCRS Members: Current Trends in Cataract Surgery in Korea

PURPOSE: This study investigates the current state of and future trends in the field of cataract surgery in Korea. METHODS: Since 1995, the members of the Korean Society of Cataract and Refractive Surgery (KSCRS) have made annual surveys on cataract and refractive surgery. The 2005 annual survey, consisting of 76 multiple-choice questions, was mailed in February 2005 to 300 KSCRS members. Sixty-six (22.0%) members answered the questions. Current data were compared with those of previous annual surveys and with those of surveys in the United States. RESULTS: Forty-six percent of the respondents were in the fifth decade. The duration of hospital stay has decreased annually and the use of topical anesthesia (44%) did not change. Self sealing wound construction was the main wound closure technique in phacoemulsification (63%). The implantation of phakic IOL was performed by 38% of the respondents and the most preferred intraocular lenses for small incision cataract surgery were acrylic (79%). Interest in the value added IOL has increased annually. CONCLUSIONS: This survey summarized current trends and changes in cataract surgery in Korea.
