This prospective study found that both OCT- and 3-D confocal structured imaging–guided femtosecond laser systems produced more centered, circular and predictable capsulotomies than manual continuous curvilinear capsulorhexis (CCC).
They randomized 60 patients to cataract surgery capsulotomy via LenSx femtosecond laser, the Lensar femtosecond laser or manual CCC.
At six months postop, there was a significantly better correlation between intended and achieved capsulotomy size in the laser groups compared to the manual group. Both laser groups also showed better capsulotomy circularity and better IOL centration than the manual group.
Furthermore, residual spherical equivalent and mean absolute error were statistically significantly smaller in the two laser groups than in the manual group. Between-group differences in corrected and uncorrected distance visual acuities were not statistically significant.
