Thirty-eight patients with urethral injury treated during the period from January 1962 to August 1964 have been studied in particular reference to sexual ability following injury and the results are summarized as follows: 1. The incidence of urethral injury was 6.8% of the total inpatients and the average in age was 23.8 years. Twenty-three cases (61.5%) were accompanied by pelvic fracture. 2. The incidence of impotence following injury was 47%, 36.4% temporary and 11.0% permanent. 3. Of 14 cases of temporary impotence, urethral injury was accompanied by pelvic fracture in 11 and all 4 cases of permanent impotence followed urethral injury accompanied by pelvic fracture. 4. Of fourteen cases of temporary impotence, previous urethral injury was complete in 6 and incomplete. in 8. Four cases of permanent impotence followed 3 complete urethral injury and one incomplete urethral rupture. 5. The average interval between the reception of trauma and the recognition of impotence was 3 to 5 months.

PURPOSE: To evaluate near, intermediate, and distant vision, optical quality, and patient satisfaction with Acri.LISA aspheric diffractive multifocal IOL. METHODS: Forty eyes of 20 patients received phacoemulsification and implantation of Acri.LISA IOL. Visual acuity was measured postoperatively at 1 week, 1 month, and 6 months. Contrast sensitivity, wavefront aberration, and visual function via questionnaire were measured at postoperative 1 month. RESULTS: Uncorrected near, intermediate, and distanct visual acuity at 1 month were 0.09 +/- 0.14, 0.29 +/- 0.17 and 0.11 +/- 0.12, respectively. At 6 months, similar visual acuity results were measured. Total and higher-order wavefront aberration values were 0.66 +/- 0.29 and 0.24 +/- 0.08, respectively. Photopic contrast sensitivity at 1.5, 3, 6, 12, and 18 cycles/degree were 1.38 +/- 0.32, 1.73 +/- 0.24, 1.75 +/- 0.21, 1.33 +/- 0.18, and 0.77 +/- 23, respectively, and mesopic contrast sensitivity values were 1.37 +/- 0.27, 1.72 +/- 0.16, 1.63 +/- 0.14, 1.01 +/- 0.19, and 0.50 +/- 0.22. Total subjective visual function score was 3,127 +/- 354, near work was 244 +/- 36, distance work was 256 +/- 21, and night driving was 221 +/- 42. CONCLUSIONS: The Acri.LISA 366D multifocal IOL can be effective for improving patient satisfaction after cataract surgery as well as for presbyopia correction.

A pacemaker-induced venous obstruction is relatively common, but is rare in cases where chronic venous occlusion has developed and progressed after the removal of permanent pacemaker leads. We report a case of permanent pacemaker implantation following percutaneous balloon venoplasty in a patient with innominate vein stenosis. The patient had a history of permanent pacemaker implantation, using a right subclavian approach, with lead extraction due to infective endocarditis 6 years earlier. Although the epicardial leads were re-implanted, once more the ventricular lead broke. When we tried to implant a new pacemaker, using a left subclavian endovascular approach, extensive venous stenoses of the innominate, right internal jugular and subclavian veins were found. As it was impossible to advance the standard pacemaker lead; therefore, percutaneous balloon venoplasty of the innominate vein was performed, and a DDD-R pacemaker successfully implanted.

Purpose:
To compare the accuracy of standard and total keratometry data obtained using the Barrett Universal II and Barrett Toric Calculator.
Methods:
In total, 111 eyes of 111 patients who visited our hospital for cataract surgery from February 2019 to September 2019 were included in this study. Total keratometry and standard keratometry data were obtained using the Barrett Universal II and the Barrett Toric Calculator; mean absolute errors were derived by using preoperative IOL Master 700® (Carl Zeiss Meditech AG, Jena, Germany) data and 2-month postoperative manifest refraction data. The mean absolute errors of the two methods were compared in terms of a posterior corneal astigmatism greater than 0.3 diopter (D) in patients fitted with Toric intraocular lenses.
Results:
Using the Barrett Universal II formula, the mean absolute error spherical equivalent difference between total keratometry and standard keratometry was 0.021 ± 0.102 D (p = 0.65) when the Barrett Toric Calculator was used. The mean absolute error differences between the two methods were 0.015 ± 0.121 D for the spherical equivalent (p = 0.80) and 0.005 ± 0.870 D for the cylinder measurement (p = 0.94). In terms of a posterior corneal astigmatism greater than 0.3 D, the mean absolute error spherical equivalent and cylinder measurement differences were -0.020 ± 0.107 D (p = 0.70) and -0.023 ± 0.055 D (p = 0.50) in patients fitted with Toric intraocular lenses.
Conclusions
The total keratometry method, which directly measures posterior corneal curvature, yields data comparable to those of the standard keratometry method. When the posterior corneal astigmatism was greater than 0.3 D, we found no significant difference between the total keratometry and standard keratometry data of patients fitted with Toric intraocular lenses.

Purpose:
To calculate the intraocular lens (IOL) power using the Shammas-PL formula after laser in-situ keratomileusis (LASIK).
Methods:
Forty-one eyes of 29 patients that had undergone cataract surgery from September 2018 to September 2019 after LASIK were enrolled in this study. A preoperative AL-Scan® (Nidek Co., Gamagori, Japan) was used to measure the axial length, anterior chamber depth, and corneal curvature. An IOL power calculation was performed using the Shammas-PL (post LASIK) formula. Mean absolute error (MAE) and mean arithmetic error (MARE) were calculated using preoperative manifest refraction and postoperative manifest refraction.
Results:
Of the 41 eyes, 15 eyes (36.6%) were relatively hyperopic-shifted after surgery compared to the predicted refractive error before surgery, 25 eyes (61%) showed a relative myopic shift, and one eye (2.4%) showed no change with respect to the previous refractive predicted error. Refractive errors before cataract surgery were not related to myopic, emmetropic, or hyperopic shifting after surgery (p > 0.05).
Conclusions
When cataract surgery using the Shammas-PL formula was performed after LASIK, myopic shifting was more common than hyperopic shifting. The MAE was greater in myopic-shifted cases than that of hyperopic-shifted cases. Thus, it is better to determine IOL power toward the hyperopic side than the target refractive prediction.

PURPOSE: To report a case of irregular astigmatism caused by a free flap during laser-assisted in situ keratomileusis (LASIK) surgery that was treated with a flap rotation based on postoperative topography. CASE SUMMARY: A 21-year-old female underwent LASIK, which was complicated by a free cap on her right eye. Because the gentian violet markings were no longer present, the exact orientation of the cap was unknown. At 3 months after surgery, the astigmatism of the right eye was −3.00 diopters (D) with an uncorrected visual acuity (UCVA) of 0.4, and the astigmatism of the left eye was −0.75 D with an UCVA of 1.0. The corneal topography was analyzed in order to return to the existing position. Free cap repositioning was performed and irregular astigmatism was corrected to improve the UCVA to 1.0. CONCLUSIONS: If the preoperative markings cannot be identified on a free flap during LASIK, secondary postoperative corneal topographic analysis can be performed to restore the corneal free flap to its original position to minimize astigmatism with good visual outcomes.

In order to provide a physiological solution for patients with breast cancer-related lymphedema (BCRL), the surgeon must understand where and how the pathology of lymphedema occurred. Based on each patient’s pathology, the treatment plan should be carefully decided and individualized. At the authors’ institution, the treatment plan is made individually based on each patient’s symptoms and relative factors. Most early-stage patients first undergo decongestive therapy and then, depending on the efficacy of the treatment, a surgical approach is suggested. If the patient is indicated for surgery, all the points of lymphatic flow obstruction are carefully examined. Thus a BCRL patient can be considered for lymphaticovenous anastomosis (LVA), a lymph node flap, scar resection, or a combination thereof. LVA targets ectatic superficial collecting lymphatics, which are located within the deep fat layer, and preoperative mapping using ultrasonography is critical. If there is contracture on the axilla, axillary scar removal is indicated to relieve the vein pressure and allow better drainage. Furthermore, removing the scars and reconstructing the fat layer will allow a better chance for the lymphatics to regenerate. After complete removal of scar tissue, a regional fat flap or a superficial circumflex iliac artery perforator flap with lymph node transfer is performed. By deciding the surgical planning for BCRL based on each patient’s pathophysiology, optimal outcomes can be achieved. Depending on each patient’s pathophysiology, LVA, scar removal, vascularized lymph node transfer with a sufficient adipocutaneous flap, and simultaneous breast reconstruction should be planned.
