Purpose: To report a case of a patient who underwent penetrating keratoplasty due to acute hydrops six years after undergoing a bilateral LASIK procedure. Methods: A 19-year old male patient with -2.75 diopter myopia received a bilateral LASIK operation at a local clinic. Forty-seven months later, -2.00 cyl axis 130o astigmatism was induced in his left eye and additional surgery was performed to correct the LASIK-induced astigmatism. The patient was referred to our hospital 16 months after the secondary operation due to reduced visual acuity in his left eye. He was diagnosed with keratectasia and acute hydrops, and penetrating keratoplasty was performed. Results: The retrospective analysis of the corneal topography prior to the LASIK surgery revealed that the inferior minus superior(I-S) value was 1.25 in the right eye and 1.3 in the left eye. At the time of the first evaluation at out hospital, a slit lamp examination showed an approximate 8x7.5mm sized area filled with aqueous humor between the corneal flap and residual stroma, and Descemet`s membrane rupture was observed. Furthermore, the histopathological section of the patient`s cornea confirmed keratocytes with myxoid degeneration and edematous change. Conclusions: In young patient, particularly those with suspicious asymptomatic keratoconus, LASIK and further enhancement surgery afterwards should be considered and approached in a cautious and deliberate manner.

The purpose of this study was to investigate the prevalence, toxin gene profiles, and enterotoxin producing ability of Bacillus cereus isolated from environment-friendly vegetables and good agricultural practices (GAP) vegetables. A total of 49 vegetables including 40 environment-friendly vegetables and 9 GAP vegetables were tested. The Vitek 2 system was used to identify B. cereus and the PCR was used to detect 6 toxin genes, respectively. B. cereus was detected in 34 (69.3%) of 49 vegetables and the prevalence of B. cereus in GAP vegetables (44.4%) was lower than in the environment-friendly vegetables (75.0%). The detection rates of entFM, nheA, hblC, and cytK enterotoxin genes, respectively, among all isolates were 100%, 97.0%, 88.2%, and 73.5%, respectively. All of the isolates had at least one or more enterotoxin gene and 20 isolates (58.8%) had hemolysin BL enterotoxin producing ability. The risk of food poisoning from the environment-friendly vegetables and the GAP vegetables has been shown as constant. Thus, it is necessary to expand the supply of GAP vegetables showing lower B. cereus contamination than the environment-friendly vegetables. The characteristics of the environment-friendly vegetables and the GAP vegetables that must be consumed after cleaning should be disseminated to consumers regarding food poisoning prevention.

Purpose: To compare the outcomes of IntraLase femtosecond laser-enabled keratoplasty (IEK) versus conventional penetrating keratoplasty (C-PKP). Methods: This retrospective study included 18 eyes of 17 patients who underwent C-PKP and 26 eyes of 25 patients who underwent IEK. Postoperative clinical results were compared between two groups. Results: The mean logMAR best spectacle-corrected visual acuity (BSCVA) was 0.70, 0.58, and 0.61 in the IEK group, and 1.06, 1.01, and 0.90 in the C-PKP group at postoperative 2, 4, and 6 months respectively. The difference between the two groups was statistically significant at 2 and 4 months postoperatively (p=0.033, 0.011). The mean refractive cylinder was 4.08 diopters (D), 4.01D, and 4.44D in the IEK group, while 5.75D, 5.75D, and 5.21D in the C-PKP group for each month, and the difference between the groups was statistically significant at 2 and 4 months postoperatively (p=0.037, 0.027). The complication rate showed no significant differences up to 6 months of follow-up between the two groups. Conclusions: The IEK showed better results in BSCVA and refractive astigmatism in the early postoperative period, in comparison with the C-PKP, and can be considered as a valuable method in penetrating keratoplasty.
