Comparison of refractive outcomes after photorefractive keratectomy with different optical zones using Mel 90 excimer laser

A larger optical zone for photorefractive keratectomy may improve optical quality and stability. However, there is need for limiting ablation diameter in that a larger ablation diameter requires greater ablati...
