A New Surgical Technique of Microkeratome-Assisted Deep Lamellar Keratoplasty With a Hinged Flap

The Effect of Femtosecond Laser Lamellar Dissection at Various Depths on Corneal Endothelium in the Recipient Bed of the Porcine Eye

“…10,11 Despite the many advantages of lamellar keratoplasty over penetrating keratoplasty, the disadvantages of lamellar keratoplasty include suboptimal visual acuity outcomes and a time-consuming procedure. [3][4][5][6]12 As such, femtosecond laser lamellar keratoplasty is an attractive option because of its good predictability for flap thickness or diameter and because it is easy to adjust flap diameter, side cut angle, side cut depth, and flap thickness. 6,7,9,13 Use of femtosecond lasers may overcome the previously described problems associated with conventional lamellar keratoplasty.…”

Femtosecond Laser Keratome Creation of Partial Thickness Donor Corneal Buttons for Lamellar Keratoplasty

“…With this decrease in postoperative corneal edema requiring endothelial replacement and the advent of modern day keratorefractive surgery, interest in lamellar keratoplasty has been renewed. Lamellar keratoplasty has many advantages over penetrating keratoplasty, including preservation of the recipient endothelium, avoidance of complications associated with open-sky surgery, decreased risk for allograft rejection, and superior wound strength 3,15–23…”

“…14 Therefore, indications IntraLase for Lamellar Keratoplasty/Sarayba et al associated with open-sky surgery, decreased risk for allograft rejection, and superior wound strength. 3,[15][16][17][18][19][20][21][22][23] Traditionally, both the donor and recipient corneas are dissected manually, ideally to identical depths. This dissection can be performed with a blunt steel instrument and aided by gas, fluid, or viscoelastic substance.…”

A Risk Score as Part of an Evidence-Based Approach to the Selection of Corneal Replacement Surgery

“…Current techniques include full-thickness penetrating keratoplasty (PK) with donor tissue, 6,7,11,[17][18][19][20][21][22] lamellar keratoplasty (LK), 23 prosthokeratoplasty with traditional keratoprostheses, 24-26 penetrating keratoplasty with new-generation flexible, biointegratable keratoprostheses 27,28 or artificial corneas, limbal stem-cell reconstruction, with or without amniotic membrane, [29][30][31] or variations of donor lamellar tissue grafting techniques, [32][33][34][35][36][37][38][39][40][41] with systemic immunosuppression considered where indicated.…”
