Photorefractive keratectomy (PRK), Keratomileusis In Situ (KM), Laser Assisted In Situ Keratomileusis (LASIK), and clear lens extraction have been performed for high myopic patients. Among the above surgical procedures KM and LASIK are applied to young patients in general. However, comparison of clinical results of these two procedures was not reported yet in Korea. To evaluate the clinical results of KM (n=16) and LASIK (n=11) for high myopic patients between -15 diopter (D) and -23 diopter (D), spherical equivalent (S.E) and uncorrected visual acuity were studied for more than ten months, retrospectively. The mean S.E. was changed from -17.36 D before operation to -3.70 D ten months after operation in KM, whereas it was from -17.41 D to -0.31 D in LASIK. At ten months after operation, uncorrected visual acuity equal or better than best corrected visual acuity before operation was 43. 8% in KM and 63. 6% in LASIK. This results show that the clinical result of LASIK were superior to that of KM for high myopia.

A case of bilateral absence of vas deference with sterility is reported. By new 15O cases of congenital absence of the vas deference, rather a rare congenital anomaly, were reported.

The superficial palmar arch of the hand is formed by the anastomosis of the palmar branch of the radial artery and the distal part of the ulnar artery. The variation of the superficial palmar arch and its branches have been known to occur frequently. There are many reports about the formation of the arch and the branches of it and the incidence of the median artery. These variations of the arch are considerablly valuable in the surgical management of the hand injuries, especially in vascular injury. This study deals with the Korean hands. The author observed the pattern of the superficial palmar arch, the presence of the median artery and the pattern of the common palmar digital arteries and the results are as followings; 1. The superficial palmar arch was complete type in 97.2% and incomplete type in 2.8%, The majority of the complete arch was type 1 and type 2. 2. The median artery was present in 2.8%. 3. The common palmar digital artery was present as type 1 in 65.3% type 2 in 13.9% type 3 in 4.2%, type 4 in 5.5%, type 5 in 6.9% and type 7 in 1.4%.

Authors decided to test whether differences occurred in automated and subjective refraction in untreated, PRK, and LASIK-treated eyes. Ninety six eyes of 50 patients(96 eyes) who underwent PRK(57 eyes) or LASIK(39 eyes) for myopia and myopic astigmatism were routinely autorefracted with the CANON RK-3 before subjective refraction was done, using several parameters. This two procedures were done preoperation and 3 months after operation. In comparing the postoperative(PRK, LASIK) results, automated refraction showed more myopia and higher cylinder power, without significant difference in refractive axis, than those of subjective measurement. The difference of cylinder power were found in the cases of large ablation depth(above 100micrometer), high degree of eccentric ablation(above 0.25 mm), LASIK operation. The significant differences of cylinder power and axis were found in the cases of high degree of eccentric ablation(above 0.25 mm). So we recommend the method of subjective refraction before PRK and LASIK operation instead of using automated refraction. Postoperatvely, we also should evaluate the postoperative status of the patient by subjective refraction. And we should decide the amount of ablation in case of retreatment by subjective refraction, instead of autorefraction. We have to be cautious of evaluating the automated refraction results after operation, especially in cases of large ablation depth, high degree of eccentric ablation, and LASIK.

Pigmented villonodular synovitis (PVNS) is a relatively rare condition. The disorder almost always involves a single joint and the knee is most commonly affected. We report on three cases of localized PVNS that involved the patella fat pad and synovium. Diagnostic and therapeutic arthroscopies were performed, and typical findings of localized PVNS were found. Complete resection of the lesions were performed arthroscopically. Arthroscopy can be used as an effective diagnostic and therapeutic tool for identification and resection of intraarticular localized PVNS of the knee.
