PURPOSE: To determine the effectiveness of the method for preventing corneal opacity and minimizing the intraocular pressure (IOP) increase after photorefractive keratectomy treated with 0.1% fluorometholone and tranilast (0.5% tranilast, Krix®, JW pharmaceutical, Seoul, Korea), especially in cases with elevated IOP. METHODS: The patients who underwent photorefractive keratectomy from May 2014 to May 2015 were enrolled in the present study. The data of 49 patients (49 eyes) with elevated IOP at 1 month postoperatively and who used 0.1% fluorometholone and tranilast eye drops (tranilast group) were analyzed and compared with the control group consisting of patients who underwent the same surgery from December 2012 to October 2013 but used only 0.1% fluorometholone. RESULTS: The visual acuity at postoperative 6 months was log MAR -0.08 ± 0.05 and log MAR -0.08 ± 0.04 in the tranilast group and control group, respectively. The eye drops were used postoperatively for 17.7 ± 3.3 weeks in the tranilast group and for 20.5 ± 3.7 weeks in the control group (p < 0.01). Anti-glaucoma eye drops were used for 18.4 ± 3.2 weeks and 20.9 ± 3.7 weeks postoperatively in the tranilast group and control group, respectively (p < 0.01). CONCLUSIONS: Adding tranilast eye drops to patients whose IOP was elevated because of 0.1% fluorometholone use after photorefractive keratectomy is an effective method for preventing corneal haze and minimizing IOP elevation.

PURPOSE: To evaluate the change of accommodation-convergence parameters after implantation of Artisan phakic intraocular lens (PIOL). METHODS: Prospective study for the patients with the Artisan PIOL implantation was performed. A total of 37 patients (3 males and 34 females) enrolled the study. Preoperatively, convergence amplitude, the stimulus accommodative convergence per unit of accommodation (AC/A) ratio and the near point of convergence (NPC) were evaluated. After the Artisan PIOL implantation, the identical evaluations were repeated at 1 week, 1, 3, and 6 months after the surgery. RESULTS: Mean age was 24.3 +/- 4.8 years old, and preoperative refractive error was -8.92 +/- 4.13 diopters (D). After the implantation, mean refractive errors significantly decreased to within +/-1.00 D, and noticeable complications were not found. The convergence amplitude and the stimulus AC/A ratio increased 1 month after the surgery, but progressively stabilized afterward to near preoperative values. NPC didn't show any significant change over follow-up period up to 6 months. CONCLUSIONS: These results regarding implantation of the Artisan PIOL revealed the increase of accommodation-convergence relationship within first 1 month after the surgery, but progressive stabilization was noted during follow-up periods.

BACKGROUND: Rocuronium, a new nondepolarizing muscle relaxant, has been reported to develop a rapid onset of action and may be suitable as a component of a rapid-sequence induction of anesthesia. Therefore we have compared rocuronium with pancuronium and vecuronium about the onset time, intubation time, and tracheal intubating conditions. METHOD: Thirty patients were divided into three groups, who were receiving intravenously pancuronium 0.14 mg/kg, vecuronium 0.1 mg/kg and rocuronium 0.6 mg/kg respectively for tracheal intubation during induction of anesthesia. The onset time(Time from drug administration to zero count of PTC) and intubation time were checked using train of four responses of the adductor pollicis muscle after ulnar nerve stimulation(2 Hz, 40mA) every 10 seconds. The intubation conditions were recorded by a "blinded" assessor as excellent, good, fair or not possible. RESULT: The onset time of pancuronium, vecuronium and rocuronium was, 125.0+/-10.0, 256.0+/-18.4 and 90.0+/-22.1 sec. respectivly. The time of intubation was 94.0+/-12.6, 95.3+/-7.9, and 77.0+/-10.6sec.(pancuronium,vecuronium & rocuronium respectively). The onset time of rocuronium was significantly faster than the other two nondepolarizing muscle relaxants. The tracheal intubation with rocuronium was possible earlier than pancuronium or vecuronium but no statistical significance was observed and the condition of intubation was excellent compare to others in all ten patients. CONCLUSION: Rocuronium may have advantages over existing non-depolarizing neuromuscular blocking agents with faster rate of development of neuromuscular block with excellent intubation condition after administraction of a dose 0.6 mg/kg(ED 95 x 2).

PURPOSE: To evaluate the effects of transient prone position on vault and anterior chamber angle parameters in ICL implanted patients. METHODS: 40 eyes of 20 ICL implanted patients with at least 1 month of follow-up were included in the present study. The central ICL vault and anterior chamber parameters including angle opening distance at 500 (AOD500) were measured with the Visante anterior segment optical coherence tomography (OCT) (Carl Zeiss, Dublin, CA) in both the sitting and prone positions by tilting the OCT 90 degrees in the vertical axis and having the patient fixate downwards towards the floor. RESULTS: The mean central vault was 0.55 +/- 0.21 mm (SD) and 0.59 +/- 0.21 mm (SD) in the sitting and prone positions, respectively (p < 0.0001). The nasal and temporal AOD500 were 0.26 +/- 0.11 mm and 0.28 +/- 0.08 mm, respectively in the sitting position, which decreased to 0.24 +/- 0.10 mm and 0.26 +/- 0.08 mm in the prone position, however, both were not statistically significant (p = 0.08, p = 0.09). AOD500 was inversely correlated with vault (r = -0.47; p = 0.0024). There were no significant correlations between increase of vault and anterior chamber depth or white to white nor ICL vault. CONCLUSIONS: Transient prone positioning of ICL implanted patients can induce a significant increase in ICL vault.

PURPOSE: To evaluate the effect of combined medical treatment with anti-glaucoma eyedrops and 0.1% fluorometholone on visual acuity and refractive errors in patients complaining of blurred vision due to myopic regression after laser-assisted in-situ keratomileusis (LASIK) or laser-assisted sub-epithelial keratectomy (LASEK). METHODS: This study comprised 155 patients (155 eyes) who were diagnosed with myopic regression after LASIK or LASEK and received medical treatment from January 2015 to January 2016. The visual acuity and refractive errors were compared before and after medical treatment and evaluated to determine whether the results differ between LASIK and LASEK. RESULTS: The mean time of medical treatment was 64.1 ± 36.8 months after surgery. The responder group whose vision was improved and whose myopic error was decreased after medical treatment was comprised of 63 patients (41%). Their visual acuity in this group improved -0.21 ± 0.11 logMAR, and the amount of myopic error decreased 0.56 ± 0.32 diopters. The full responder group was 24 patients (15%), and the partial responder group was 39 patients (26%). The frequency of response to medical treatment was higher after LASIK than after LASEK, but the difference was not statistically significant. CONCLUSIONS: The combined medical treatment with anti-glaucoma eyedrops and 0.1% fluorometholone was effective in 41% of patients with regard to visual acuity improvement when used for post-LASIK or post-LASEK myopic regression. The medical treatment was effective after both LASIK and LASEK.

PURPOSE: To investigate clinical findings, diagnostic criteria and management for patients with congenital periodic alternating nystagmus (PAN). METHODS: A retrospective analysis of clinical findings and electrooculography (EOG) of patients with congenital PAN was performed. Thirteen patients diagnosed with congenital PAN from March 1992 to December 2002 were included. RESULTS: Of 13 patients, the median age at initial visit was 7 years old (range: 1 to 30 years). Eight patients had abnormal head posture. The mean value for the period of alteration was 265.7 seconds. Six patients who received either the modified Kestenbaum-Anderson procedure or four rectus muscle recession showed a significant decrease in amplitude and/or frequency of nystagmus, and showed statistically significant improvement in visual acuity in LogMAR after the procedures by 0.33+/-0.09 in right eye, 0.34+/-0.11 in the left eye, compared with preoperative acuities of 0.43+/-0.19 and 0.38+/-0.09 respectively. CONCLUSIONS: Congenital PAN requires the evaluation of nystagmus along with a thorough evaluation of eye movement and EOG. Close follow is necessary to evaluate the pattern of nystagmus. Also, either modified Kestenbaum-Anderson procedure or four rectus muscle recession could be effective, depending on the presence of abnormal head posture.

We evaluated the one-stage intraoperative adjustment strabismus surgery with adjustable suture under topical anesthesia. Medical records of the patients who had intraoperative adjustment surgery under topical anesthesia for horizontal or vertical strabismus in our hospital from March 1997 to March 2003 with follow-up of 6 months were analyzed retrospectively. Of the 71 patients, 48 patients had exotropia, 16 had esotropia, and 7 had hyper- or hypotropia. The overall success rates were 85.9% at 1 week, 83% at 1 month, 78.9% at 3 months, and 76.1% at 6 months after surgery. The procedure was not stopped in any patients, and no serious intra-operative or postoperative complications were noted. Intraoperative adjustment strabismus surgery under topical anesthesia is a simple, well-tolerated and effective procedure.

Giant cell tumors of the bone commonly occur in the epiphyseal scar of a long tubular bone, representing about 5% of all primary bone tumors. A short tubular bone, such as one in the hand or foot, is the site of less than 5% of all giant cell bone tumors. The authors report two cases in which giant cell tumors arose in the short tubular bone, and describe the clinical manifestations and radiologic findings.
