Purpose:The aim of this study was to describe clinical experience using femtosecond laser-assisted anterior capsulotomy in eyes with previous radial keratotomy.Methods:Eyes of patients with previous radial keratotomy and cataract-related vision impairment who underwent phacoemulsification and intraocular lens implantation were retrospectively reviewed. Eyes with any vision impairment cause other than cataract or previous radial keratotomy were excluded.Results:Sixteen postradial keratotomy eyes were included. In 5 patients, manual anterior capsulectomy was successfully performed. Six eyes underwent femtosecond laser capsulotomy using routine parameters (incision depth 500 m and 4 J power), of which in 3 eyes capsulotomies were complete, whereas in the other 3 eyes incomplete capsulotomy was evident. In 3 patients, both incision depth and power parameters were doubled (incision depth 1000 m and 8 J power), whereas in 2 patients, only the pulse energy was doubled (8 J power) and in all 6 cases, the capsulotomy was successfully completed. At the last follow-up, all capsulotomies were intact without radial tears, and the intraocular lenses were stable and central.Conclusions:Radial corneal scars after previous radial keratotomy may interfere with femtosecond laser-assisted anterior capsulotomy using routine parameters. Surgeons should be alert and ready to convert to manual anterior capsulectomy. Modification of the laser parameters may overcome this potential complication.
