15.1 Case 1: Corneal scar with RK incisions and cataract
This patient was referred with a central on-corneal scar with multiple RK incisions and cataract. As
a first step, he underwent scar peel with excimer laser myopic ablation to clear the cornea and make
it measurable. After IOL power calculation, he then underwent cataract surgery with a precisely
calculated lens implant and was brought to emmetropia and unaided 20/20 vision.
