The femtosecond laser is being used with increasing popularity to create incisions for customised trephination in penetrating keratoplasty.1 Several femtosecond laser assisted keratoplasty (FLAK) pattern designs have been studied,2–5 all demonstrating superiority of various shaped cuts (particularly the Top-Hat) over traditional vertical trephination in resistance of the wound to leakage from elevated intraocular pressures (IOP).
One of the disadvantages, however, of the more popular FLAK patterns such …
