Randomized Clinical Trial of OCT-Guided Laser-Assisted Lamellar Anterior Keratoplasty in Adults for Stromal Opacities
The purpose of this protocol is to compare and develop new surgical technique of partial-thickness corneal transplantation for treating corneal opacities. Two newly developed techniques, “zigzag” dual laser-assisted lamellar anterior keratoplasty (LALAK) and “dovetail” LALAK, will be tested and compared with standard full-thickness corneal transplantation.
Eyes with corneal opacities that cannot be adequately or safely corrected with spectacles, contact lens or laser surface treatment.
