Patients and Methods
This prospective study included the initial 200 consecutive femtosecond laser cataract surgeries, refractive lens exchange surgeries, or both performed at the Vision Eye Institute by 7 surgeons (M.L., G.S., T.V.R., Colin Chan, David Ng, Simon Chen, and Mark Jacobs) between April 2011 and June 2011. Three surgeons ((M.L., G.S., Colin Chan) had prior extensive experience with the use of the femtosecond laser in LASIK. The study conformed to the tenets of the Declaration of Helsinki. Ethics
Results
The initial 200 consecutive eyes were included in the study. The mean age of the patients was 69.2±9.8 years. Table 1 lists the baseline characteristics of patients included in the study.
Of the 200 eyes, the laser procedure was completed successfully with respect to capsulotomy, lens fragmentation, and primary corneal and secondary corneal incisions in 153 eyes. None of the cases underwent arcuate keratotomy. In 9 eyes, the laser procedure included capsulotomy and lens segmentation without the
Discussion
The ultrashort-pulse femtosecond lasers have been developed to increase the precision of and to minimize the collateral tissue damage in ocular surgery. Because power is a function of energy and time, the use of shorter pulses decreases the energy output and hence leads to better preservation of ocular structures. Recent experimental and human studies have reported the applicability of femtosecond lasers in cataract surgery.17, 18 Phacoemulsification surgery remains the standard for cataract
