PurposeWe report on 15 cases of suspected toxic anterior segment syndrome after uneventful phaco surgery.MethodsWe retrospectively reviewed the charts of patients who had developed toxic anterior segment syndrome (TASS) after uneventful phacoemulsification for senile cataracts between April and December of 2005. Clinical features and all possible causes were investigated including irrigating solutions or drugs, surgical instruments or intraocular lenses, sterilization techniques for instruments, or any other accompanying disease.ResultsThe patients consisted of 2 males and 13 females with an average age of 64.7±10.9 years. Five different surgeons had performed their phaco surgeries. No abnormal preoperative or operative findings were reported. Nevertheless, all 15 patients developed a moderate degree of corneal edema. Ordinary treatments were not helpful. We suspect that lack of sterilization resulted in the development of the syndrome, because after ethylene oxide gas sterilization was replaced with autoclaving, no such incidents have occurred.ConclusionsToxic anterior segment syndrome requires special attention and thorough management, including sterilization of reused surgical instruments.
In this study in which a properly constructed continuous curvilinear capsulorhexis was created and IOLs were accurately placed in normal capsular bags, changes in ACD, IOL decentration and tilt, and BCVA were similar in eyes with a PMMA, silicone, or soft acrylic IOL.
Purpose: To compare posterior capsular opacification (PCO) between a combined procedure and a sequential procedure of pars plana vitrectomy (PPV) and cataract surgery (CS). Methods: The medical records of 89 eyes of 85 patients who underwent PPV and CS were retrospectively reviewed. There were 56 eyes of 52 patients with a combined PPV and CS (the combined surgery group), and 33 eyes of 33 patients with CS in a previously vitrectomized eye (the sequential surgery group). The control group was comprised of 130 eyes of 102 patients who underwent CS alone. All patients were followed up for at least 1 year after CS. The major outcome measures were the PCO rate and the interval between CS and PCO formation. There were no significant differences in age and the incidence of diabetes among the 3 groups. Results: The PCO rate checked at 1 year after CS was 12.5% (7/56) in the combined surgery group, 24.2% (8/33) in the sequential surgery group, and 4.6% (6/130) in the control group. The differences in the PCO rate between the subgroups as well as among the 3 groups were statistically significant (p < 0.05). There were no significant differences in the interval between CS and PCO formation among the 3 groups. Conclusion: This study demonstrates that the PCO rate may be lower in patients who have a combined procedure of PPV and CS than in those who have a sequential procedure.
A 33-year-old woman visited our clinic with blurry vision and periorbital swelling after experiencing blunt trauma to left eye. Ten months earlier, she had implantable contact lens (ICL) implantation in the left eye. Biomicroscopic examination showed that that 1 footplate of the ICL was entrapped in the pupillary aperture at the 7 o'clock position and the ICL was placed vertically. The patient had limited ocular movement in lateral gaze, and the computed tomography showed a medial orbital wall fracture. Pupillary capture of the ICL was surgically corrected with an iris manipulator under topical anesthesia. After the ICL was repositioned, the patient's uncorrected visual acuity was restored to 20/32, as before the injury. Pupillary capture of the ICL may occur after blunt ocular trauma.
Purpose: This study investigated the current trends and changes in the field of cataract surgery in Korea. Methods: The members of the Korean Society of Cataract and Refractive Surgery (KSCRS) and the members of the Korean Ophthalmological Society (KOS) participated in a survey on cataract surgery in 2012, the 16th survey, consisting of 108 multiple-choice questions, mailed in July 2013 to 301 KSCRS and KOS members. Sixty two (20.6%) members answered the questions. Current data were compared with previous surveys performed in 2006 and 2009. Results: Most of the respondents (46%) were in the fourth decade, 43% in the fifth decade and 10% in the sixth decade of life. The duration of hospital stay had decreased annually and the use of topical anesthesia (69%) was the most preferred. Self-sealing wound construction was the main wound closure technique in phacoemulsification (72%). The most preferred intraocular lens (IOL) for cataract surgery was hydrophobic acrylic (76%) which showed an increasing trend. The implantation of phakic IOL was performed by 41% of the respondents and interest in the value added IOLs such as presbyopia IOL and toric IOL had increased annually. In addition, to minimize astigmatism following cataract surgery, several methods were performed according to the degree of astigmatism. However, there was little interest in new cataract surgery techniques such as femtosecond laser and many respondents were skeptical whether to adopt the femtosecond laser cataract surgery system. Conclusions: This survey summarized current trends and changes in the field of cataract surgery in Korea.
