| Popis: | The purpose of this study was to investigate the efficacy and safety of arcuate cuts with a 5-mm optical zone to correct high postoperative astigmatism after extracapsular cataract extraction. We performed 5-mm optical zone arcuate cuts on 23 eyes of 23 patients with high postoperative astigmatism. Ophthalmic examination included uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA) and the amount of the refractive and keratometric cylinder before and 9 months after operation. Surgically induced refractive change was calculated in all cases. A significant reduction in astigmatism was achieved in all cases with minimal axis deviation. No case developed clinically significant irregular astigmatism. The mean magnitude of astigmatism of the surgically induced refractive change calculated from standard keratometry and refractive data was 3.73 ± 0.72 and 3.70 ± 0.77 dptr, respectively. The mean axis deviation calculated from the keratometric and refractive data was 1.18 ± 2.33 and 1.32 ± 3.62°, respectively. At the last examination, 78.2% of the eyes had UCVA of 20/40 or better. No eye lost more than two lines of vision, 6 eyes lost one line, 2 eyes gained one and 1 eye gained two lines of BSCVA. The above data show that the 5-mm optical zone arcuate astigmatic keratotomy is an effective and safe method of correcting high postoperative astigmatism. |
