Comparison of Nd: YAG capsulotomy rate between 1-piece and 3-piece acrylic intraocular lenses: A STROBE-compliant article.

The aim of the study is to compare Nd:YAG capsulotomy rate between acrylic 1- and 3-piece intraocular lenses. Among 924 eyes of 762 patients who received cataract surgery, we selected the 303 patients (404 eyes) implanted with an SN60WF 1-piece intraocular lens (Alcon, Fort Worth, TX) or a YA-60BBR 3-piece intraocular lens (Hoya Co., Tokyo, Japan). For intraindividual comparison, we enrolled the 17 patients implanted with an SN60WF in 1 eye and a YA-60BBR in the contralateral eye. We compared Nd:YAG capsulotomy rate between acrylic 1- and 3-piece intraocular lenses 24 months after the operation. Of the 404 eyes in this study, Nd:YAG capsulotomy was performed in 20 of 268 eyes (7.5%) in the SN60WF 1-piece intraocular lens group and 24 of 136 eyes (17.6%) in the YA-60BBR 3-piece intraocular lens group; the difference was statistically significant (P = .002). Among the 17 patients (34 eyes) who were implanted with 2 different inraocular lenses, Nd:YAG capsulotomy was performed in only 2 eyes (12%) in the SN60WF group and 9 eyes (53%) in the YA-60BBR group; the difference was statistically significant (P = .020).The authors found a significantly greater incidence of Nd:YAG capsulotomy in eyes who received 3-piece lenses compared with those who received 1-piece lenses.

Choroidal volume in branch retinal vein occlusion before and after intravitreal anti-VEGF injection.

PURPOSE: The aim of this study is to evaluate the subfoveal choroidal volume change in the patients with branch retinal vein occlusion before and after intravitreal anti-vascular endothelial growth factor injection using the enhanced depth imaging optical coherence tomography. METHODS: We measured the bilateral subfoveal choroidal volume in 15 patients (mean age, 64.47 ± 7.13 years) with unilateral branch retinal vein occlusion by using the enhanced depth imaging methods of the Spectralis optical coherence tomography system. After an injection of intravitreal bevacizumab, we measured the subfoveal choroidal volume of the eye with regressed macular edema. RESULTS: The mean subfoveal choroidal volume measured in 15 eligible eyes of 15 patients was 7.74 ± 0.70 mm, which was significantly greater than the volume of the fellow eyes (6.38 ± 0.69 mm; P = 0.001, Wilcoxon signed-rank test). The subfoveal choroidal volume of the eye with regressed macular edema was 6.56 ± 0.79 mm, which was significantly lower than the volume before the treatment (P = 0.001, Wilcoxon signed-rank test). CONCLUSION: The subfoveal choroidal volume of the branch retinal vein occlusion eyes was significantly greater than the volume of the fellow eyes and decreased significantly after an intravitreal anti-vascular endothelial growth factor treatment.

Oral steroid therapy as an adjuvant treatment for severe epidemic keratoconjunctivitis in patients younger than 3 years.

PURPOSE: To evaluate the therapeutic effect of oral steroids given to patients younger than 3 years with epidemic keratoconjunctivitis (EKC) accompanied by severe eyelid edema and inflammatory ptosis, in whom eye drops were not feasible. METHODS: This study included 9 patients treated for EKC in local clinics whose condition failed to improve due to severe eyelid swelling together with difficulties in application of eye drops and pseudomembrane removal. We analyzed the extent of eyelid swelling, corneal damage, follicles, chemosis, and pseudomembrane formation in these patients before and after oral corticosteroid therapy in collaboration with the pediatrics department. RESULTS: After a mean of 1.8 ± 0.7 days of oral steroid treatment, eyelid edema, corneal damage, conjunctival injection, follicles, and chemosis improved in all patients. CONCLUSIONS: Oral steroids are an effective adjuvant treatment for EKC in patients younger than 3 years in whom eye drops could not be administered frequently due to severe eyelid edema.
