시력교정(라식, 라섹, 엑시머)수술이 근시환자의 삶의 질에 미치는 영향에 대하 기존 연구들이 있었으나, 수술을 받은 환자들을 대상으로 수술 전후의 삶의 질 변화를 조사하는데 그쳤다. 본 연구에서는 시력교정 수술을 받은 환자들과 수술을 받지 않고 안경이나 콘택트렌즈를 계속 착용하는 사람들의 삶의 질을 비교 분석하였다. 근시환자 470명에 시력관련 삶의 질을 평가하기 위하여 QIRC(The Quality of Life Impact of Refractive Correction)설문지를 한국어 번역판을 개발하여 사용하였다. 공분산분석(ANCOVA)을 이용하여 주요혼란변수를 보정 한 후 안경 및 콘택트렌즈 착용 자, 시력교정수술을 받은 자. 그리고 수술 후 안경을 재 착용하는 자 등 세집단간의 삶의 질을 비교한 결과 시력교정수술을 받은 군은 안경이나 콘택트렌즈로 교정을 받은 군에 비해서 삶의 질이 유의하게 높았다. 그러나 수술 후 근시로 이행하여 안경을 재 착용하게된 군의 삶의 질은 수술을 하지 않은 군보다 더 삶의 질이 낮은 것으로 조사되었다. 시력교정수술이 근시환자의 삶의 질에 미치는 영향을 평가하기 위해서는 시력교정수술 후에도 다시 안경을 착용해야 하는 경우 수술 전보다 삶의 질이 더 낮아질 수 있다는 점을 고려하여야 할 것으로 보인다.

This study was performed to analyze the optical aberrations of the cornea induced by myopic refractive surgery. Corneal total higher-order aberrations, spherical aberration and coma for 4-mm and 6-mm pupils were measured using a wave-front analyzer. The amount of aberrations of the oblate corneal optics by the achieved correction was found to be larger than for the prolate corneal shape with complete eye, in an emmetropia control group. The change in corneal shape acts as an optical factor that degrades the quality of the retinal image; it seems to be one of the important factors related to quality of vision.

The purpose of this study was to evaluate the cause of lens luxation and to determine the frequency of vision loss, glaucoma, cataract, and corneal edema before and after intracapsular lens extraction (ICLE). The medical records of 8 dogs underwent ICLE for the correction of anterior lens luxation at the Veterinary Medical Teaching Hospital of Seoul National University from August 2005 to September 2007 were reviewed. The most frequently affected breed was Miniature Poodle (n = 3). The mean age was $10.8{\pm}2.1$ years. Preoperatively, 5 eyes (67.5%) with anterior luxation had secondary glaucoma, 7 eyes (87.5%) had vision loss, and all eyes (100.0%) had corneal edema. Four weeks after ICLE, 6 eyes (75.0%) had normal intraocular pressure (IOP), and 4 eyes (50.0%) regained vision. Corneal edema was reduced after ICLE in all eyes, but still remained in 4 eyes. It was considered that ICLE was beneficial in the management of anterior lens luxation, but the eyes without glaucoma before ICLE had more favorable prognosis than eyes with.

Membranous obstruction of the inferior vena cava[IVC] is a rare congenital anomaly that may present clinical features of Budd-Chiari syndrome caused by chronic obstruction of hepatic drain. We have experienced a case of IVC obstruction caused by hour-glass constriction and membrane in its center. Operative correction was accomplished using profound hypothermia [20%] and total circulatory arrest of 26 minutes. This technique permitted resection of membrane with direct vision and removal of thrombus of IVC and hepatic vein. After then constricted IVC was repaired with autologous pericardial patch. Total circulatory arrest was used intermittently for good visual field. Postoperative course was smooth and postoperative angiography showed unobstructed flow through the IVC in spite of slight constriction of cavoatrial junction and nearly complete disappearance of collateral vessels.

Background Many people have an interest in the correction of facial scars or deformities caused by trauma. The increasing ability to correct such flaws has been one of the reasons for the increase in the popularity of facial plastic surgery. In addition to its roles in communication, breathing, eating, olfaction and vision, the appearance of the face also plays an important role in human interactions, including during social activities. However, studies on the importance of the functional role of facial appearance. As a function of the face are scare. Therefore, in the present study, we evaluated the importance of the functions of the face in Korea. Methods We conducted an online panel survey of 300 participants (age range, 20-70 years). Each respondent was administered the demographic data form, Facial Function Assessment Scale, Rosenberg Self-Esteem Scale, and standard gamble questionnaires. Results In the evaluation on the importance of facial functions, a normal appearance was considered as important as communication, breathing, speech, and vision. Of the 300 participants, 85% stated that a normal appearance is important in social activities. Conclusions The results of this survey involving a cross-section of the Korean population indicated that a normal appearance was considered one of the principal facial functions. A normal appearance was considered more important than the functions of olfaction and expression. Moreover, a normal appearance was determined to be an important facial function for leading a normal life in Korea.

Purpose: The aim of this study is to compare total high order aberrations between surgery which uses TransPRK and general laser assisted sub-epithelial keratomileusis. Methods: The patients who had general laser assisted sub-epithelial and TransPRK laser assisted sub-epithelial by visiting ophthalmic clinic in Ulsan from January 2014 to August 2014 was researched. Results: When comparing total high order aberrations before and after operation, it was found that total high order aberration in general laser assisted sub-epithelial group increased to $0.222{\pm}0.078{\mu}m$ from $0.074{\pm}0.019{\mu}m$ while that in TransPRK assisted sub-epithelial group increased to $0.179{\pm}0.045{\mu}m$ from $0.076{\pm}0.032{\mu}m$. When comparing the increment in total high order aberrations between two groups after surgery, it was found that the increments of TransPRK assisted sub-epithelial group were statistically smaller than that of general laser assisted sub-epithelial group (p<0.05). Conclusions: This study made a comparative analysis of total high order aberrations between general laser assisted sub-epithelial and TransPRK assisted sub-epithelial which was introduced recently and the result showed a significant difference. The findings of this study suggest that TransPRK assisted sub-epithelial can be used widely in simply improving eye sight and quality of vision by reducing an increase in high order aberration caused by orthokeratology surgery. It is expected that TransPRK assisted sub-epithelial will be helpful for improving the understanding quality of eye sight which occurs by several methods of vision correction surgery.

Purpose: Paraffin has been used to augment depressed nasal contour for many years by illegally. Reported complications of nasal paraffinoma were skin thinning, displacement of nasal profile, redness, chronic inflammation and malignant change to skin cancer. The current authors report results of the secondary rhinoplasty after excision of nasal paraffinoma. Methods: Through the open rhinoplasty incision, paraffinoma was removed under direct vision. Saline irrigation and meticulous hemostasis were performed. Simultaneously, the secondary depressed nasal deformity was corrected with autogenous dermofat graft harvested from inferior gluteal fold. The dermofat was fixed to the nasofrontal area with bolster suture, and the interdormal area of the tip. Results: A total of 13 patients underwent secondary augmentation with autogenous dermofat graft after removal of paraffinoma from 2000 to 2004. The mean follow-up period was 15 months. There were no postoperative complications. All patients were satisfied with their surgical results. However, there were 10 to 20 percent resorption of the grafted dermofat. Conclusion: It is suggest that autogenous dermofat be one of good materials for the correction of the secondary deformity after removal of nasal paraffinoma. In addition, autogenous dermofat graft presented easy harvesting and manipulation for transfer, high survival rate by firm fixation to the recipient site and stable surgical results.

Purpose: Reduction malarplasty is a popular aesthetic surgery for contouring wide and prominent zygoma. However a few patients complain postoperative results and want to revise the midfacial contour. We analyzed the etiology of unfavorable results and treated unsatisfied midfacial contours after reduction malarplasty. Methods: Total 53 patients were performed secondary operation for correction of unfavorable results after primary reduction malarplasty from elsewhere. Midfacial contour was evaluated with plain films and three-dimensional computed tomography. Unfavorable midfacial contours were corrected by secondary malarplasty. Flaring of zygomatic arch was reduced with infracturing technique and prominent zygomatic body was reduced with shaving. Drooped or displaced zygoma complex has been suspended to higher position and fixed with interosseous wiring. As adjuvant procedure, autologous fat injection has been performed in the region of depressed zygomatic body region. Results: The etiology of unfavorable midfacial contour after reduction malarplasty was classified into 7 categories: undercorrection of zygomatic arch(n=8), undercorrection of zygomatic arch and undercorrection of zygomatic body(n=6), undercorrection of zygomatic arch and overcorrection of zygomatic body(n=28), overcorrection of zygomatic body(n=3), simple asymmetry(n=4), malunion(n=2) or nonunion(n=2). Slim and balanced malar contour was achieved with treatment. And most of the patients were satisfied with the results of the surgery. Conclusion: To prevent the unfavorable results after reduction malarplasty, complete analysis of facial contour, choice of appropriate operation technique, precise osteotomy under direct vision, and security of zygoma position are important.
