PURPOSE: To compare the effect of femtosecond laser-assisted cataract surgery with conventional cataract surgery on effective phacoemulsification time (EPT). METHODS: This study included 66 patients 100 eyes who underwent femtosecond laser-assisted cataract surgery and 68 patients 100 eyes who underwent conventional cataract surgery. Both groups underwent phacoemulsification using pulsed ultrasound energy and EPT was evaluated. The groups were further analyzed according to preoperative Lens opacities classification system (LOCS) III grading. Patients who had femtosecond laser-assisted cataract surgery underwent lens fragmentation with quadrant, hybrid, or grid pattern and the EPT was respectively evaluated. RESULTS: The mean EPT was 5.85 +/- 4.31 seconds in the femtosecond laser-assisted cataract surgery group and 10.34 +/- 6.61 seconds in the conventional group. Overall, EPT was statistically significantly lower in the femtosecond laser-assisted cataract surgery group compared to the conventional group. When the groups were analyzed according to LOCS III grading, this result was consistent for all cataract grades and the reduction in EPT was increased with the higher LOCS III grade. When the groups were analyzed according to lens fragmentation patterns, the mean EPT was lower with 350 microm grid pattern than the quadrant or hybrid pattern. CONCLUSIONS: The femtosecond laser-assisted system in cataract surgery can be an efficient cataract surgery using lower EPT compared to the conventional procedure. Additionally, significant differences were observed in the mean EPT of cataract surgery using the femtosecond laser-assisted system among the 3 lens fragmentation pattern groups.

PURPOSE: We report 2 cases treated with bilobed flap surgery for medial canthal reconstruction. METHODS: Two patients with black and painless lid mass, 1 x 1 cm size, developed at medial canthal area were excised, and medial canthal reconstruction was performed. Biopsy was done before the surgery, showing basal cell carcinoma. We designed and rotated bilobed flap to reconstruct medial canthal defect caused by the radical excision, and sutured it at the incision margin of the skin. RESULTS: Pathologic examination was done after the surgery, confirming basal cell carcinoma. No marginal cancer cell were detected. Cancer relapse did not occur during 12 months of follow-up. We obtained satisfactory results in all patients, not only clinically but also cosmetically. CONCLUSIONS: It is considered that the bilobed flap procedure is effective for reconstruction of medial canthal defect developed after eyelid tumor excision and offer a good prognosis.

Testicular lymphomas are rare, accounting for only 5% of all testicular tumors. The majority of these tumors are part of the disseminated disease process, and only rarely arise as a primary lesion. Most testicular lymphomas are B-cell lymphomas. Testicular T-cell lymphomas, are rarely detected, but have many subtypes according to the immunohistological feature, and have poor outcome and high relapse rates, even with a localized disease. Herein, 2 cases of testicular T-cell lymphoma, initially manifesting in the testis, are reported, with a review of the clinical features and outcomes.

Crossed testicular ectopia is a rare anomaly, in which both testes migrate toward the same hemiscrotum. Fewer than 100 cases of this condition have been reported in the literature worldwide. Occasionally, conditions initially suspected to be crossed testicular ectopia have proven to be other anomalies, including hypospadias, renal agenesis, and seminal vesicle cysts. In this case, we diagnosed ganglioneuroblastoma in a patient with testicular ectopia.

Ganglioneuroma is a rare benign tumor which originates in the neural crest, and is found along the path of the sympathetic chain, from the base of the skull to the pelvic cavity. Due to the slow growth of this type of tumor, it may be detected incidentally, or detected by virtue of the attendant pressure effects on adjacent structures. We report one case of ganglioneuroma arising in the pelvic cavity.

BACKGROUND: Elderly patients with underlying cardiovascular or respiratory diseases are more susceptible to anesthesiologic risks or serious complications following laparoscopic operations. We evaluated the safety of laparoscopic radical nephrectomy in elderly patients to compensate for the lack of Korean data on the subject in the field of urology. METHODS: From March 2003 and March 2009, 73 patients with localized renal cell cancer underwent laparoscopic radical nephrectomy. They were divided into two groups according to age; 75 years or older (elderly group, n=21) and under 75 years (young group, n=52). Operative parameters as well as oncological outcomes were evaluated. RESULTS: The mean age was 77.7+/-2.5 years for the elderly group and 55.9+/-10.5 years for the young group. No significant differences existed between the groups in terms of mean operative time, intraoperative blood loss, complications, and hospital stay. However, American Society of Anesthesiologists (ASA) score, co-morbidities (p<0.05), and rate of transfusion (p<0.05) were significantly higher in the elderly group. In overall analyses, we conclude that in elderly patients undergoing laparoscopic radical nephrectomy, close monitoring of hemoglobin level as well as intraoperative transfusion for maintenance of hemoglobin level at 10 mg/L or higher is necessary in elderly patients to achieve adequate circulation. CONCLUSION: Laparoscopic radical nephrectomy can be considered a safe and effective procedure for most elderly patients.

PURPOSE: The subconjunctival sparganosis is rare tissue helminthiasis which developed frequently in abdominal, urethral, ureteral and vertebral cases. Authors report a case of sparganosis in the subconjunctival mass. METHODS: A 51-year-old man with reddish non painful mass in his left eye on the subconjunctiva that was unresponsive to medications for 6months was evaluated and treated surgically. On surgical exploration, a white thread-like plerocercoid 0.2 x 4.7 cm in size was extracted from the subconjunctival mass and actively motile in the bottle filled with saline. It was confirmed as a typical sparganum under histologic examination. Three months after surgery, the lesion disappeared completely. RESULTS: Although rare, parasitic disease should be suspected in a palpable subconjuntival mass unresponsive to the medical treatment.

There are 3 surgical treatments for the management of post-prostatectomy incontinence, including endoscopic injection of periurethral bulking agent, perineal sling procedure, and artificial urinary sphincter (AUS). 4 patients with post-prostatectomy incontinence in our hospital underwent sling procedure using polypropylene mesh. All patients were evaluated for urodynamic result, pad count, operative time, hospital stay, complication, success, and satisfaction. Mean age was 67.8years (64-75). Mean follow-up time was 38.5months (30-51). 2 patients underwent radical prostatectomy, and other 2 patients underwent transurethral prostatectomy. Of the 4 patients, 3 (75%) were successful. In satisfaction, 2 (50%) were unsatisfied due to recurrent incontinence and erectile dysfunction. The male sling procedure using polypropylene mesh is a simple, effective treatment and an additional therapeutic option.

PURPOSE: To evaluate the efficacy of anterior segment swept-source optical coherence tomography (SS-OCT) for examining horizontal extraocular muscle thickness, distance from the corneal limbus to the insertion of the horizontal extraocular muscle (limbus to insertion distance), and scleral thickness in Korean pediatric strabismus patients. METHODS: This study included pediatric strabismus patients between 5 and 10 years of age. Children with any ocular disease other than strabismus or a history of ocular surgery were excluded. SS-OCT was used to measure horizontal extraocular muscle thickness, limbus to insertion distance, and scleral thickness. Eyes were classified into subgroups by sex, spherical equivalent of the refractive error (measured with cycloplegic refraction), and fixating/deviating eye. RESULTS: One patient initially included in this study was excluded due to poor cooperation. Of the remaining 35 eyes of 20 patients, 19 eyes (54.3%) were from male patients and 16 eyes (45.7%) were from female patients. The mean patient age was 7.86 ± 1.38 years. Lateral scleral thickness was greater in male eyes than in female eyes (p = 0.048). No other differences were noted between male and female children. Additionally, there were no statistically significant differences between fixating and deviating eyes or among spherical equivalent groups for any parameter examined. CONCLUSIONS: Anterior segment SS-OCT can successfully and comfortably measure horizontal extraocular muscle and scleral anatomy in children. These measurements may be helpful for treatment and follow-up of pediatric strabismus patients.
