DESIGN: Prospective, noncomparative case series. PARTICIPANTS: Twenty-one eyes (20 patients; age range, 58-87 years) treated at clinics of the Taipei Veterans General Hospital were included in this study. METHODS: Paired linear incisions (90 degrees in length) with a central optical zone (OZ) of 4.5 mm were made to correct high astigmatism in older patients. The incisions were 80% of the corneal thickness and parallel to the axis of the steepest cylinder. MAIN OUTCOME MEASURES: Refraction, keratometry, corneal topography, and visual acuity with and without correction were measured as the outcome indicators. RESULTS: The mean course of the stabilization of corneal curvature was 1.8 months. Significant improvement from a preoperative corneal astigmatism of 4.52+/-1.39 D to a postoperative value of 1.82+/-0.88 D (P<0.0001) was shown. Marked axis deviations of more than 30 degrees were observed in 5 cases and corneal perforation was observed in 1 case. When the corneal curvature stabilized, uncorrected visual acuity was improved by 2 lines or more in 15 eyes (71.4%). Spherical equivalents and best-corrected visual acuity did not change significantly. Postoperative glare was absent in all patients. CONCLUSIONS: We conclude that AK by linear-long incisions extending from a small OZ is effective and safe for correcting astigmatism. ------>tmu_sno=None ------>sno=20204 ------>authors2=Chen KH ------>authors3=Hsu WM ------>authors4=Lee SM ------>authors5=Chiang CC ------>authors6=Li YS ------>authors6_c= ------>authors=Ho HC ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Linear-long incisions with a small optical zone for the correction of astigmatism in older patients. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=1 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2004 ------>submit_flag=None ------>publish_month=1 |
