Femto PK: A change in the corneal transplant paradigm

The advent of femtosecond (FS) laser technology has changed the landscape of modern corneal transplantation surgery. Laser corneal transplant surgery produces consistently excellent outcomes with numerous benefits for the patient, including a significantly shorter healing time, superior wound integrity, and lower levels of regular astigmatism.

Manual penetrating keratoplasty (PK) surgery is an inexact science historically plagued by its inherent unpredictability. Problems often en countered with manual techniques include graft/host-sizing disparity, prolonged recovery time of up to 1 year, and high levels of irregular astigmatism and wound instability, among others. Utilization of the iFS Advanced Femtosecond Laser (Abbott Medical Optics, AMO, Santa Ana, Calif.) in my practice has eliminated most of these elements due to the ability to produce precisely matching donor and host shapes and enhance the healing wound interface.
