RESUMEN
@#AIM: To study the effects between low concentration atropine and orthokeratology on myopia prevention and control.<p>METHODS: Totally 150 cases of juvenile outpatients with myopia were chosen in our hospital. They were divided into 3 groups randomly. Group A(50 cases)were treated with low concentration atropine. Group B(50 cases)were treated with orthokeratology. Group C(50 cases)were treated with spectacles. Refractive degree and ocular axial length had no statistically significant differences between three groups before treatment. After 1a follow-up, refractive degree and ocular axial length of three groups were statistically analyzed. <p>RESULTS: After 1a, the refractive degree changes of each group before and after treatment were statistically significant(<i>P</i><0.01). The results of refractive degree changes among the groups were as follows: there was no significant differences between low concentration atropine group and orthokeratology group(<i>P</i>>0.05); compared with orthokeratology and low concentration atropine group, that of spectacles group was significantly different(<i>P</i>>0.05). After 1a follow up, the ocular axial length changes of each group before and after treatment were statistically significant(<i>P</i><0.01). The results of ocular axial length changes among the groups were as follows: there was no significant differences between low concentration atropine group and orthokeratology group(<i>P</i>>0.05); compared with orthokeratology and low concentration atropine group, that of spectacles group was significantly different(<i>P</i><0.05). <p>CONCLUSION: The effects of low concentration atropine and orthokeratology on controlling juvenile myopia and ocular axial length have no significant difference. They are superior to spectacles on controlling juvenile myopia.
RESUMEN
To observe the clinical efficacy of Artisan iris-clip intraocular lens ( lOL) implantation on cataract with a wide range of lens dislocation. ●METHODS: Twenty-four hospital patients (28 eyes) of cataract with lens subluxation by trauma (20 patients, 20 eyes) and Marfan's syndrome (4 patients, 8 eyes) during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris - clip lOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo. ●RESULTS: Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0. 1-0. 5 was in 20 eyes, 0. 5-1. 0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed. ●CONCLUSlON: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris - clip lOL implantation and obtain a better outcome.
