Abstract:
We evaluated the safety and efficacy of photo-astigmatic refractive keratectomy(PARK) with Schwind excimer laser for one year. We performed PARK procedures on 28 eyes with compound myopic astigmatism. Twenty eight eyes were divided into two groups according to their astigmatism: low(up to -1.5D, 15 eyes), high(over -1.5, 13 eyes). Mean preoperative astigmatism was 1.17+/-0.28 in low astigmatism group and 2.67+/-0.90 in high astigmatism group. Mean one year postoperative astigmatism was 0.40+/-0.39 in low astigmatism group and 0.48+/-0.56 in high astigmatism group. Correction rate of astigmatism was 62.3% in low astigmatism group and 79.4% in high astigmatism group. Complications were loss of best corrected visual acuity 2 line or more(2 eyes), temporary increased intraocular pressure(4 eyes), over 0.25mm eccentric ablation(2 eyes). We concluded that the Schwind excimer laser PARK appeared to be a safe and relatively accurate proceudre to correct myopic astigmatism, especially predictability of astigmatism correction was very satisfactory.
