Analysis of femtosecond laser assisted capsulotomy cutting edges and manual capsulorhexis using environmental scanning electron microscopy.

Purpose. To investigate the structure and irregularity of the capsulotomy cutting edges created by two femtosecond (FS) laser platforms in comparison with manual continuous circular capsulorhexis (CCC) using environmental scanning electron microscopy (eSEM). Methods.

Optimal parameters to improve the interface quality of the flap bed in femtosecond laser-assisted laser in situ keratomileusis.

Purpose: To analyze the interface quality of the anterior stroma after femtosecond laser flap creation using atomic force microscopy.

Setting: IRCCS Fondazione G.B.

Sixty-kilohertz femtosecond laser-assisted endothelial keratoplasty: clinical results and stromal bed quality evaluation.

Purpose: To evaluate preliminary clinical results and lamellar and side cut obtained with a 60-kHz femtosecond laser (IntraLase) using a new software designed to create penetrating cuts for keratoplasty to perform the donor and recipient dissection in femtosecond laser-assisted endothelial keratoplasty.

Design: Prospective interventional case series.

Methods: A femtosecond laser set in a raster spot pattern was used to create the posterior lamellar dissection and posterior side cut in 4 donor corneas and in 4 recipient human eyes of 4 patients with endothelial decompensation.

The use of the femtosecond laser in penetrating keratoplasty.

Purpose: To evaluate a new technique for penetrating keratoplasty (PK) with the use of a new software algorithm for a femtosecond laser that is designed to create penetrating cuts for PK in the treatment of a number of corneal diseases.

Design: Prospective, interventional case series.

Methods: All eyes were treated at the Ospedale Civile di Mestre, Umberto, Italy.

Visual acuity and contrast sensitivity comparison between Tecnis and AcrySof SA60AT intraocular lenses: A multicenter randomized study.

Purpose: To evaluate best corrected visual acuity (BCVA) and photopic and mesopic contrast sensitivity in pseudophakic patients implanted either with the aspheric intraocular lens (IOL) designed to correct for corneal spherical aberration or with a conventional IOL.

Setting: Three surgical centers participated this prospective randomized masked comparative study.

Methods: Thirty eyes of 30 patients after aspheric lens implantation (Pfizer/Pharmacia Tecnis Z9000) were compared with 30 eyes of 30 age-matched patients after conventional lens implantation (Alcon AcrySof SA60AT).
