conclusions by using the normal angle kappa determined in this study, pseudodeviations can be identified more precisely in those who might undergo keratorefractive surgery. results a total of 977 healthy participants who aged 18 to 45 years were included consecutively. the study population consisted of 614 females and 363 males. the average angle kappa was 5.00º ± 1.36º at 240.21º ± 97.17º in m...

purpose: the impact of photo refractive keratectomy compared with using glasses or contact lens on patient’s quality of life (qol) in myopia. method: in this retrospective cohort study, 102 myopic patient who had undergone prk (at least 6 months ago) and 106 myopic patients using glasses or contact lens were included. changes in vision related qol, uncorrected and best corrected visual acuity (...

PURPOSE A seventh annual survey was carried out by mail in February 1999 to investigate the current trends in cataract and refractive surgery in Japan. METHODS Questionnaires were sent to 925 ophthalmologist members of the Japanese Society of Cataract and Refractive Surgery. Data received from 411 (44.4%) of the recipients were cross-analyzed and compared with those from the previous surveys....

Since the early 1980s, civil airmen have been allowed to correct refractive error (i.e., myopia, hyperopia, astigmatism) with corrective surgery. Prior Federal Aviation Administration research studies have shown that the number of civil airmen with refractive surgery continues to increase. A study that reviewed refractive surgery use in civil airmen for the years 1994-96, reported that the larg...

the coverage of soft- tissue defects of the hand specially volar side needs special consideration. although certain local flaps have been described and used for resurfacing the palm, extensive injury requires distant or free flaps for coverage. abdominal pedicle flap has been traditionally used for extensive hand injuries, however there is no doubt that one of the ideal tissues for resurfacing ...

introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...

Several laser and non-laser refractive surgical procedures have been used to modify the shape of the cornea and correct myopia, hyperopia, astigmatism, and presbyopia. Introduction of the excimer laser to reshape the cornea has resulted in remarkable developments in the correction of these refractive errors. Combined with other advanced ophthalmological instruments, laser refractive eye surgery...

purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...

The corneal wound healing response following refractive procedures represents a subject of high relevance, due to its direct influence on the postoperative results. Technical modifications of current refractive procedures, like the automated flap creation with the femtosecond laser, LASEK, PRK with mitomycin C and Epi-LASIK have been proposed as alternatives to traditional LASIK and PRK. Severa...
