Purpose To report the visual out comes and graft survival rate of mushroom keratoplasty using femto second laser for the treatment of full thickness cornea opacities and healthy endothelium. Methods Retrospective chart view of 23 eyes (low risk of immunologic reactions n = 12; high risk n = 11) undergone femtosecond assisted mushroom keratoplasty. The mushroom shaped graft consisted of a large top hat (9 mm diameter + 250 microns in thickness) and small stalk (6–6.5 mm). The wavelight FS 200 laser parameters used on this platform for the donor and recipient corneas are described. Outcome measures were BCVA best corrected visual acuity refraction, corneal topography, endothelial cell density, graft rejection and graft failure at 1, 3, 6 and 12. Results Average follow up was 9 months (range 6–15) months. All grafts were clear at the last follow up visit. Excluding eyes with pre existing ocular co‐morbidities. The percentage of patients achieving BCVA of 20/40 or better at 1, 3, 6 and 12 months was 66.7%, 90.50%, 95.2% and 100%, respectively. At last follow up the refractive cylinder was 6 diopters (D) or less in all eyes, averaging 3.7 D. Two eyes (8.7%) had rejection that were easily reversed with topical steroids. Conclusions Femtosecond‐assisted mushroom keratoplasty ( FAMK ) shows faster visual recovery, better visual acuity and limited postoperative astigmatism with no increase risk of rejection.
