RESUMO
The purpose of this research was to carry out a prospective clinical study of patients with transverse maxillary deficiency, orthopaedically expanded after minimum osteotomies of the zygomatic pillars and the median palatine suture, with quantitative assessment of the stability of the transverse dimensions of the maxilla. The distance between the superior canines and the first superior molars was measured six times during the clinical experiment. The desired expansion was achieved by 15 days postoperatively for all patients. After one year of follow-up, clinical measurements showed a relapse rate of 23% in the superior canine area and 18% in the superior first molar area.

PURPOSE: The aim of the study was to study the results of LaAIK for myopia over -12.00 D. METHODS: Surgery was done using Hansatome microkeratome and Nidek EC-5000 excimer laser. One hundred forty-five eyes were followed for a minimum of 6 months to assess the extent of correction and the gain or loss of lines as compared of previous spectacle correction. RESULTS: Forty percent of eyes gained at least one line, 56% remained the same, and 4% lost one line of visual acuity. Thirty-five eyes were undercorrected with the majority between 0 and -5.00 D. One hundred ten eyes achieved their preoperative best spectacle-corrected visual acuity with no correction. Complications were minimal. CONCLUSION: LASIK with the Nidek EC-5000 excimer laser achieved good results in eyes with myopia over -12.00 D. [J Refract Surg 2000; 16(suppl):S247-S250].
RESUMO
The first 500 posterior chamber lenses inserted in the capsular bag, have been analysed in detail. The cases included in this study were developmental, traumatic and complicated cataracts in addition to senile cataract. The follow-up ranged from 6 months to 2 years. Although posterior capsule rupture occurred in 23 cases, the lens was inserted in 12 cases with a small tear. In general the complications were found to be minimal and visual recovery was good in more than 80% of the cases. The only problems we have been facing were thickening of the posterior capsule (11.6%), high astigmatism (12.2%), pupillary capture (5.6%) and decentering of the lens (2.8%).
