Femtosecond laser-assisted clear corneal incisions may cause less damage
Femtosecond laser-assisted clear corneal incisions resulted in less tissue damage and better wound morphology than manual incisions, according to a study.
The prospective study analyzed 60 eyes of 60 patients who underwent cataract surgery with clear corneal incisions. Femtosecond laser-assisted incisions were created in 30 eyes, and manual incisions were created in 30 eyes. The LenSx system (Alcon) was used in all laser-assisted procedures.
Patients underwent evaluation of manifest refraction, corneal topography, tonometry and endothelial cell counts before and after surgery.
Uncorrected distance visual acuity and corrected distance visual acuity improved significantly in both groups (P < .001). Both groups had similar surgically induced astigmatism. Keratometric astigmatism was significantly lower in the femtosecond laser group than in the manual incision group at 1 month and 6 months (both P < .05).
The laser incision group had significantly higher central endothelial cell count than the manual incision group at 7 days and 30 days after surgery (P < .05).
Corneal thickness at the incision site increased less in the laser incision group than in the manual incision group at 1 month and 6 months (P < .05).
Total phacoemulsification time was significantly lower in the femtosecond laser incision group than in the manual incision group (P < .05).
