<p>Purpose: To examine the long-term occurrence and course of Elschnig pearl (string of pearls) formation along neodymium:YAG (Nd:YAG) laser posterior capsulotomy margins. Setting: Department of Ophthalmology, Keio University School of Medicine, Tokyo, Japan. Methods: The clinical records of eyes having an Nd:YAG posterior capsulotomy to treat posterior capsule opacification after cataract surgery were retrospectively reviewed. Kaplan-Meier and Cox proportional hazards analysis were performed. Results: Among 201 eyes, string of pearls developed in 139 (69.2%). The mean follow-up after the Nd:YAG posterior capsulotomy was 32.1 months ± 25.3 (SD)(SID). At 2 years, the cumulative probability of developing string of pearls was 77.0% (95% confidence interval [CI], 70.6%-83.4%), after which it reached a plateau. Among the 139 eyes, 100 had sufficient data to be reviewed to assess the long-term outcome (mean follow-up from Nd:YAG posterior capsulotomy, 43.7 ± 26.0 months). A second Nd:YAG posterior capsulotomy was performed in 18 eyes (18.0%) to treat progression of string of pearls, typically within 2 years after the initial Nd:YAG capsulotomy. The string of pearls disappeared spontaneously in 31 eyes (31.0%). The probability of disappearance was 80.4% (95% CI, 63.4%-97.4%) 8 years after the Nd:YAG posterior capsulotomy. Cox proportional hazards analysis identified no factor significantly favoring the disappearance of the string of pearls. Conclusions: String of pearls was a common complication after Nd:YAG laser posterior capsulotomy. About 20% of cases were progressive and required a second capsulotomy; however, most regressed over several years. © 2002 ASCRS and ESCRS.</p>

　View Summary

<p>Purpose: To evaluate the efficacy and safety of an ozonated solution used as a preoperative disinfectant and to irrigate the corneal flap in laser in situ keratomileusis. Methods: In normal human eyes, the rates of positive bacterial culture before and after irrigation were compared for 3 kinds of solutions: a 1:16 solution of povidone-iodine, a hypotonic-ozonated solution, and an isotonic-ozonated solution. In white rabbit eyes, the conjunctival fomix of the eye was irrigated with one of the 3 solutions before a corneal flap was made. Then the flap was irrigated with one of these 3 solutions: a hypotonic-ozonated solution, an isotonicozonated solution, or a balanced salt solution (BSS). The degree of corneal epithelial damage, the degree of edema in the flap after irrigation, and postoperative wound healing were compared in rabbit eyes exposed to the 3 solutions. Results: In human eyes, all 3 solutions were effective preoperative disinfectants. In rabbit eyes, the degree of corneal damage was more severe in the eyes irrigated with povidone iodine solution than in those irrigated with other solutions. There was no noticeable difference in the degree of flap edema after irrigation under the flap or in wound healing among eyes irrigated with BSS or an ozonated solution. Conclusions: An ozonated solution is an effective preoperative disinfectant and causes less corneal damage than a povidone iodine solution. An isotonic ozonated solution could be used to irrigate under the corneal flap during laser in situ keratomileusis.</p>
