Abstract Details


To describe the results of the first Bowman Layer (BL) Transplant performed in the United States


Parker Cornea/ Tertiary Referral Center


One eye of one patient with advanced, progressive keratoconus was treated by BL transplantation, in which an isolated donor BL was implanted within the mid-stroma of a recipient cornea. At one day, week, month, and three months postoperatively; visual acuity and corneal clarity, density, thickness, and topographic measurements were recorded and compared to their preoperative values.


The day after surgery, best spectacle corrected vision was 20/40. One week postoperatively, the cornea was thin and clear with the profile of the BL graft only barely visible by slit-lamp examination. By three months, whereas both corneal density and thickness were unchanged, maximum keratometry values had fallen from 62.9 diopters (D) to 58.3 D. With a rigid contact lens the preoperative visual acuity of 20/30 was restored. No intra- or postoperative complications were observed.


Early evidence suggests BL transplantation to be a safe and effective means of flattening and stabilizing corneas with advanced keratoconus.
