Femtosecond laser-assisted in situ keratomileusis with topography-guided or asphericity-adjusted derived data: a comparative contralateral eye study.

Background: Wavefront-optimized laser-assisted in situ keratomileusis (LASIK) ablation is the most commonly performed procedure in refractive surgery, but new technologies have become available. Our goal was to compare topography-guided (Contoura) and asphericity-guided (Custom-Q) customized ablation treatments for the correction of myopia with or without astigmatism.

Methods: This prospective, randomized, double-blind, contralateral eye study included 60 eyes of 30 patients with myopia or myopic astigmatism requiring femtosecond LASIK (FemtoLASIK) treatment.

Artificial tears alone versus 0.45% ketorolac tromethamine with artificial tears for the treatment of acute viral conjunctivitis.

Purpose: To evaluate the effects of preservative-free 0.45% ketorolac tromethamine and artificial tears (carboxymethylcellulose) compared with those of preservative-free artificial tears alone on the symptoms and signs of acute viral conjunctivitis.

Methods: This was a randomized, double-masked clinical trial that included 50 patients who were diagnosed with acute viral conjunctivitis and distributed into two groups (Group 0: artificial tears and Group 1: 0.
