Femtosecond laser-assisted cataract incisions: architectural stability and reproducibility.

There is considerable interest in the potential relationship between postoperative endophthalmitis and clear corneal tunnel incisions for cataract surgery. Earlier work from Ernest et al. clearly demonstrated that incisions that are square in surface architecture are significantly more resistant to deformation and leakage than those that are rectangular. The purpose of this preliminary investigation was to determine whether corneal tunnel incisions could be constructed with femtosecond laser technology and in a manner that would preclude deformation and leakage at any intraocular pressure (IOP).
