Capsulotomy morphology in cataract surgery: comparison of five femtosecond lasers

Different laser platforms produce morphologically and quantitatively distinct irregularities, which may influence capsulotomy strength differently. FEMTO LDV Z8, a low-energy laser, did not produce a smoother capsulotomy than the high-energy lasers. Our results suggest that, with current technologies, the precision of the laser is more important than the pulse energy in determining the regularity of the capsulotomy surface.
